GABA worked amazingly for 18-year-old during a MCAS/histamine flare, helping with OCD, anxiety, rage and skin issues

By Trudy Scott Leave a Comment

gaba mcas

Bonnie shared how effective GABA was for her 18 year old son with suspected MCAS (mast cell activation syndrome/histamine issues) and his associated anxiety/OCD/rage and skin issues:

GABA worked amazingly for us during a flare! Flares began with OCD [obsessive compulsive disorder]and anxiety increasing before our eyes and then the rage followed.

He would wake up very early and his upper back, shoulders and upper chest would have acne all over, this would come and go, but never completely go.

GABA capsules worked in 20 minutes and thanks to you Trudy, I read and found GABA chewables worked in 5 minutes. We used to buy GABA all the time to stop the flares and to prevent them from coming! The GABA was absolutely 100% a godsend!

Once I started focusing on keeping histamine down, we don’t buy or use GABA much! Haven’t had a flare in almost a year!!

It’s so wonderful to hear that GABA helped Bonnie’s son so much. No MCAS/histamine flare in a year!

I checked with Bonnie and they primarily used 3 x Source Naturals GABA Calm chewables (each one contains 125 mg GABA). They initially used up to 3 x 250 mg GABA if he was having a really bad flare, 1 if he was not so bad and 2 if somewhere between.

Histamine issues frequently cause physical tension and anxiety so we’d expect GABA to help. Wth rage and OCD, we typically consider low serotonin as a possible cause but in her son’s case, GABA clearly was his root cause. I share another case where GABA helped ease symptoms of anger, rage, and dark moods.

It’s been a long road – ruling out PDD-NOS, PANDAS and PANS

But as amazing as GABA was for him there was more to it and it has been a long road for him. Bonnie shared this too: “At 4 years old he was diagnosed with PDD-NOS, then at 5 years old they said no it’s PANDAS, and at 6 years old no it’s PANS.”

Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS) refers to a group of disorders characterized by impairment in the development of social interaction, verbal and non-verbal communication, imaginative activity and a limited number of interests and activities that tend to be repetitive.

Both PANDAS and PANS are associated with OCD, rages and other mental health issues which are often sudden onset and caused by infections – PANDAS is Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections, and PANS is when the severe onset of OCD symptoms is linked to another infection. More on these conditions here. It’s important to either rule out or address these conditions.

They tried several doctors and several protocols over the years: “B12 injections early but only saw a small gain. No reactions for years whatever we tried. IV treatment about 5 years ago was the second time we had gains.

Histamine was off the chart and flares were worse during allergy season and better in winter

I share all this to give you hope and to send the message that you don’t want to ever give up. Even with few gains, Bonnie persevered and started making the connections with allergies. She shared this: “During these years 2 different allergy tests matched and histamine was off the chart for both, but 2 different doctors did not address it. Maybe there was no connection then.”

She noticed flares were worse during the beginning of allergy season and better in winter, and started to histamine support:

We use DAO enzymes with high histamine foods. We tried quercetin, isoquercetin and curcumin with no gains. Started stinging nettles and bromelain and they are definitely helping us with gains.

Our son seems to be much better, being more social and we are just seeing better connections socially.

Just started Seeking Health Serotonin Nutrients to see if this can further add gains. Probably a different topic now! Sorry so long!! Love to share!!!

Bonnie noticed her son’s flares were better in winter but keep in mind there may be seasonality of GABA with worsening anxiety, insomnia and intrusive thoughts in winter (and the need for increased GABA supplementation). I blog about this here.

The research: Neurotransmitter and neuropeptide regulation of mast cell function

Bonnie shared her son’s results in response to a Facebook post where I shared the research that GABA (a well-known inhibitory neurotransmitter) helps with MCAS/mast cell activation syndrome and histamine issues.

This 2020 paper, Neurotransmitter and neuropeptide regulation of mast cell function: a systematic review, reports that:

Some reports link GABA to the inhibition of MC (mast cell) activation in allergies. GABA suppresses degranulation in rat basophilic leukemia RBL-2H3 cells via the GABA(B) receptor on the cell surface

….The administration of GABA in a dose-dependent manner reduced the development of AD [atopic dermatitis] – like skin lesions in mice by suppressing serum IgE and splenocyte IL-4 production.

(Keep in mind that the RBL-2H3 cell line mentioned in the above research is a commonly used histamine-releasing cell line used in inflammation, allergy and immunological research.)

My additional feedback about serotonin support and pyroluria

They also used (and still use) 5 mg lithium orotate and 100 mg 5-HTP. Bonnie will soon be stopping one at a time to see if that makes a difference. I’ll share what she reports back.

Bonnie mentions wanting to trial a combination product for serotonin support. I shared with her that I prefer individual amino acids so we know what’s helping. This is especially important with sensitive folks who may react to any one of the ingredients. My choice would be exploring 5-HTP further or doing a trial of tryptophan instead of 5-HTP (or possibly a combination of both) if there are still low serotonin symptoms.

She also mentions that her son is “more social and we are just seeing better connections socially.” This is great but if she feels he could make even more social gains I’d encourage looking into the pyroluria protocol too. There are many added benefits of addressing pyroluria (a social anxiety condition) when someone has MCAS, histamine issues, Lyme or another chronic condition. The zinc, vitamin B6 and other nutrients also support neurotransmitter production.

Resources if you are new to using amino acids as supplements

We use the symptoms questionnaire to figure out if low GABA or low serotonin may be an issue.

If you suspect low levels of any of the neurotransmitters and do not yet have my book, The Antianxiety Food Solution – How the Foods You Eat Can Help You Calm Your Anxious Mind, Improve Your Mood, and End Cravings, I highly recommend getting it and reading it before jumping in and using amino acids on your own so you are knowledgeable. And be sure to share it with the practitioner/health team you or your loved one is working with.

There is an entire chapter on the amino acids and they are discussed throughout the book in the sections on gut health, gluten, blood sugar control, sugar cravings, anxiety and mood issues.

The book doesn’t include product names (per the publisher’s request) so this blog, The Antianxiety Food Solution Amino Acid and Pyroluria Supplements, lists the amino acids that I use with my individual clients and those in my group programs. You can find them all in my online store.

If, after reading this blog and my book, you don’t feel comfortable figuring things out on your own (i.e. doing the symptoms questionnaire and respective amino acids trials), a good place to get help is the GABA QuickStart Program (if you have low GABA symptoms too). This is a paid online/virtual group program where you get my guidance and community support.

If you are a practitioner, join us in The Balancing Neurotransmitters: the Fundamentals program. This is also a paid online/virtual program with an opportunity to interact with me and other practitioners who are also using the amino acids.

I really appreciate Bonnie for sharing her son’s story and giving me permission to share as a blog.

Has GABA helped with your symptoms (or your loved one’s symptoms) triggered by MCAS/mast cell activation syndrome and histamine issues – like anxiety, insomnia, OCD, racing heart, rage, allergy symptoms and even rashes/dermatitis?

Do you also find that the sublingual/chewable GABA Calm product worked/works quicker than swallowed GABA products?

Has addressing pyroluria helped MCAS/histamine issues and social anxiety?

Seriphos lowers high cortisol: prevent waking in the night and nighttime anxiety

By Trudy Scott 63 Comments

seriphos and cortisol

Seriphos is my favorite nutrient for lowering high nighttime cortisol in order to reduce night waking and nighttime anxiety. I’ve used it with success in the past and have just needed it again:

After coming back from Hawaii (I was there for just under 2 weeks), I was still waking a few times each night. Sometimes I would be awake for 2-3 hours! I’m a hot mess when I don’t get sleep through the night. With just 1 Seriphos before bed for 9 days I was sleeping through the night again. It was glorious!

High cortisol can be a temporary issue after international travel i.e. caused by jetlag and out of balance circadian rhythm. I will admit that I have a number of confounding factors – like my loss and grief (my darling mom has just passed away), being sprayed with insecticide on landing in Australia (which I suspect caused severe vertigo the day after I got back), and high blood pressure (and likely higher cortisol too) after drinking too much licorice tea for my voice loss. Whatever the causes of my high cortisol, Seriphos really helped me sleep through the night.

I ran out of Seriphos 2 nights ago and I was awake for 3 hours last night. I’ll be adding it back to my nighttime protocol as soon as my order arrives.

Seriphos is made by Interplexus and is a phosphorylated serine product. It is similar to the more recognized phosphatidylserine which is also used and known for lowering high cortisol – clinically and in the research.  However, clinically, I have found Seriphos to be more effective and work more quickly.

UPDATE Feb 2024: I did end up tweaking my Seriphos dose a few times. After a few weeks I decided to trial 2 per night – this worked well. Then a few weeks later I trialed 3 per night – but after a few days I realized that even though it worked well for sleep it made me too tired the next day. For this reason I went back down to 2 Seriphos at bedtime.

UPDATE August 2024: I’m now using just 1 Seriphos at night and have added ox bile supplementation and a bright light panel in the morning because of bile issues. More on this below.

Seriphos for high cortisol due to trauma, loss of beloved cat and more

When I posted this on Facebook, I had a number of folks share how Seriphos has also helped them.

Kathy shared this: “I take two Seriphos at night for high cortisol that causes insomnia. It works well for me and helps me to relax. I have a significant trauma background that keeps me in fight or flight, so Seriphos is a must have at night. I do take a break from time to time if I am going through a less stressful time.”

Hopefully Kathy is also working on the trauma, doing trauma work and even incorporating other nutritional approaches which help so much with recovery – like zinc, vitamin D, a B complex, GABA and tryptophan etc. Taking a break from time to time is a good plan – I share more about this below.

Kim shared this: “Seriphos is a life saver – I started it when I was having cortisol/adrenaline issues a few years ago and have continued using it. I don’t ever want to be without Seriphos. A little over a month ago I unexpectedly lost my youngest cat. She was emaciated when I rescued her over 4 years ago and we turned around health issues. I feel so sad that she was dealt such a bad hand but we got her a loving home. My animals are everything to me and the grief is so difficult. She was a character and I love her so much.”

She uses one capsule in the evening but also uses a capsule during the day if she feels off. Hopefully Kim is also doing trauma work and other nutritional support too.

Janie shared this: “I have used it, years ago when my cortisol was off the charts, morning and at night. I was awake every night until 2am, unable to sleep. Seriphos certainly helped.”

She used 1 Seriphos per day for about 3 months.

Patricia said: “Please remember that there is Original Seriphos and the next gen Seriphos. I was one of thousands of people who had used original Seriphos for sleep and then they changed their formulation without telling us and then so very many of us were wide awake at night until we realized that they had changed the formulation.”

This happened in 2016/2017 and I blogged about that whole fiasco here –  Seriphos Original Formula is back: the best product for anxiety and insomnia caused by high cortisol. You can read many other success stories on the blog and in the comments.

Address the causes of your high cortisol: jetlag, grief, toxins, licorice intake

As you can see from my example there can be a number of causes of high cortisol and you always want to address these causes while using Seriphos so you can eventually stop using it:

  • International travel i.e. caused by jetlag and out of balance circadian rhythm. I’m home so this is no longer a contributing issue.
  • Loss and grief can have physiological effects and high cortisol is one of many effects: “It appears that cortisol remains elevated for at least the first 6 months of bereavement. For some, cortisol elevation may become chronic”. The loss of my darling mom is going to take time but I am making time for grieving and I’m nurturing myself. As I navigate this period in my life I’ll continue to share what has helped me. I suspect I may need Seriphos for longer than the usual 3 months.
  • Being sprayed with insecticide on landing in Australia (which I suspect caused severe vertigo the day after I got back). It’s well-recognized that environmental toxins are hormone disruptors and affect the hypothalamic-pituitary-adrenal (HPA) axis and cortisol. I’m addressing this with active detoxification and my portable infrared sauna.
  • High blood pressure and likely higher cortisol too after drinking too much licorice tea for my voice loss. I have stopped the licorice consumption and my blood pressure is back to normal.

Other possible causes of high cortisol include day to day stresses, food sensitivities such as gluten, high sugar consumption, parasites and so on. Each factor needs to be addressed.

I do recommend Salivary cortisol testing before using Seriphos

Salivary cortisol testing is something I do with all my clients anyway. And I do recommend salivary cortisol testing before using Seriphos and the other cortisol-lowering nutrients mentioned below.

I will admit that I didn’t follow my own recommendation because I’ve had high nighttime cortisol in the past and recognized the symptoms. I had also identified all the above root causes and I desperately needed to sleep. I now have an adrenal saliva test kit on hand and will report back when I get the results.

Seriphos will only work for waking in the night if cortisol is high

One woman shared “I have never slept through the night in years. It would be delightful to get to the morning without waking.” Seriphos will very likely help if her cortisol is high.

Keep in mind there are many causes of not being able to sleep through the night and Seriphos will not help if cortisol is not high. Other root causes for insomnia/waking in the night (and nighttime anxiety) we consider and investigate are:

  • Low GABA and low serotonin (I always start with these while waiting for salivary cortisol results to come back),
  • Low melatonin

The following factors need to be addressed as root causes of sleep issues, anxiety and other symptoms (like gut issues, pain etc.), and also keep in mind that they are very possibly contributing to your high cortisol too:

A few folks reported they had tried Seriphos without success and it may well be that they don’t have high cortisol. Or they would possibly benefit from another approach to lower their cortisol (more on this below).

What are my options if I have high cortisol at night and Seriphos has the opposite effect?

One person said it had the opposite reaction. Joanne shared this: “Seriphos had the opposite effect on me. [One Seriphos] gave me extreme anxiety, kept me awake all night. Saliva tested consistently high cortisol at night so it should have helped. Been trying to work out why it would and how it might inform how I treat my insomnia.”

I’ve had a few clients do better with less than the recommended 3 per day and one not being able to use it at all. I suspect an allergic reaction or that it’s just too high a dose for some folks. The capsule could be opened and less could be used.

If this doesn’t work, other options for lowering high cortisol include lactium/hydrolyzed casein, Relora® (which contains Magnolia officinalis and Phellodendron amurense), essential oils such as bergamot and some herbal adaptogens. You can also read about some phosphatidylserine products I looked into when the Seriphos product was changed.

Forest bathing also helps to lower high cortisol levels and I recommend it for everyone.

Where does using Seriphos fit into everything else that I’m doing to address my insomnia and/or anxiety?

I typically don’t start with Seriphos right away with clients unless we know cortisol is high. As mentioned above I always start with assessing for low GABA and low serotonin and we do trials of the respective amino acids based on the symptoms questionnaire.

I also assess for low blood sugar and dietary factors like gluten, caffeine, sugar, quality animal protein intake etc. as covered in my book “The Antianxiety Food Solution.” More about my book here.  It does include a chapter on the amino acids and how to use them too.

Then we start to dig deeper and would consider Seriphos or lactium for anxiety caused by high night time or even high morning cortisol or high cortisol at other times of the day.

With many folks all of the above often applies. And we continue with assessing for each of the 60+ nutritional and biochemical root causes of anxiety/waking in the night (which does include liver/gallbladder/bile issues).

Where do I purchase Seriphos and how much do I use? What about taking a break?

seriphos

You can purchase Seriphos from my online store (Fullscript – only available to USA customers – use this link to set up an account) and you can also find it on iherb (use this link to save 5%).

The bottle states to use 1 capsule with water 15 minutes before a meal. Clinically, using 1-3 capsules a few hours before the high cortisol seems to be most effective. For 2-4am waking this typically means taking Seriphos right before bed. In some instances, taking 1 on waking in the night can help too (for a maximum of 3).

With high cortisol in the night and on waking, I have clients use Seriphos before bed and lactium on waking.

It is recommended to take a one-month break after 3 months of Seriphos use. Ideally, once the root causes of high cortisol are addressed, you should be able to stop anyway.  Or take a break, retest cortisol and then continue.

I’ll share some research and how Seriphos differs from phosphatidylserine in a follow-up blog if there is enough interest.

I appreciate all the feedback from these women in my community.

Have you used Seriphos (a phosphorylated serine product) to help with high cortisol and waking in the night/nighttime anxiety caused by any of the?

What do you suspect the cause(s) of your high cortisol is or was? And have you confirmed high cortisol with a saliva cortisol test?

Have any of the other products mentioned above helped to reduce high cortisol? If yes, have you compared them with Seriphos?

Let me know if you’re interested in a follow-up blog that includes some research and how Seriphos differs from phosphatidylserine.

Licorice intake, the renin-angiotensin-aldosterone-system and licorice-induced adverse effects on the cardiovascular system

By Trudy Scott 28 Comments

licorice intake

Licorice, today chiefly utilized as a flavoring additive in tea, tobacco and candy, is one of the oldest used herbs for medicinal purposes and consists of up to 300 active compounds.

The main active constituent of licorice is the prodrug glycyrrhizin, which is successively converted to 3β-monoglucuronyl-18β-glycyrrhetinic acid (3MGA) and 18β-glycyrrhetinic acid (GA) in the intestines.

Despite many reported health benefits, 3MGA and GA inhibit the 11-β-hydrogenase type II enzyme (11β-HSD2) oxidizing cortisol to cortisone. Through activation of mineralocorticoid receptors, high cortisol levels induce a mild form of apparent mineralocorticoid excess in the kidney and increase systemic vascular resistance.

Continuous inhibition of 11β-HSD2 related to excess licorice consumption will create a state of hypernatremia [high sodium], hypokalemia [low potassium] and increased fluid volume, which can cause serious life-threatening complications especially in patients already suffering from cardiovascular diseases.

The above is from the paper, Bioactive Candy: Effects of Licorice on the Cardiovascular System and builds on the recent licorice-hypertension blog, showing a “correlation between licorice intake, the renin-angiotensin-aldosterone-system and licorice-induced adverse effects on the cardiovascular system.”

Adverse effects on the heart

As you can see from the above image, there are many ways that licorice intake can adversely affect the heart.

Most folks are aware of the issues with licorice causing high blood pressure and some folks know it can lower potassium. However, many folks are not aware of some of these more severe cardiovascular consequences caused by high blood pressure and  severely low potassium:

Hypertension is one of the major concerns for our healthcare system and was the leading contributor to premature death in 2015.  It has been proven to be a major risk factor of cardiovascular diseases.

Some of the mechanisms include “increased stiffness of large arteries” and “pulmonary edema …caused by the sodium retaining effect of licorice” (this is high blood pressure in your pulmonary arteries, which carry oxygen-poor blood from your heart to your lungs. The earliest symptom is shortness of breath during your usual routine).

In addition to hypertension, the paper mentions the following:

  • “Cardiac arrhythmias are the most serious side effect caused by licorice intake due to severe hypokalemia” (i.e. irregular heartbeat due to low potassium).
  • “Depletion of the body’s potassium stores can cause a prolongation of the QT interval, which is closely connected with ventricular arrhythmias and tachycardia” (i.e. abnormal heartbeats and increased heart rate).
  • “As a consequence, several patients experienced a cardiac arrest with a subsequent recovery.”

I encourage you to read the entire paper in order to fully understand the “correlation between licorice intake, the renin-angiotensin-aldosterone-system and licorice-induced adverse effects on the cardiovascular system.”

Who may be more susceptible to the adverse impacts of licorice intake?

There are many documented health benefits of licorice and the above paper outlines how it may even benefit the heart. However some folks are more susceptible to the adverse effects and the above paper shares who may be more adversely impacted by licorice intake:

  • People aged over 40
  • Patients with a history of cardiac disease (and high blood pressure). I’ll also add those with family members with heart or blood pressure issues
  • Patients who are on medicines lowering potassium levels (such as thiazide or loop diuretics)
  • Patients treated with antihypertensive drugs such as ACE-inhibitors and diuretics
  • Patients suffering from diarrhea or alcoholism, which can worsen hypokalemia
  • Patients with congestive heart failure or resistant hypertension
  • Patients taking digoxin or warfarin to avoid the risk of toxicity

The authors also state that “women seem to be more susceptible to licorice intake. A possible explanation for this gender difference are many other hormonal (estrogenic and antiandrogenic) effects exhibited by licorice in addition to its activity via mineralocorticoid receptor.” And that licorice should also be avoided during pregnancy “because the conversion of cortisone into cortisol plays an important role in lung maturation.”

These other possible factors from this paper, Licorice abuse: time to send a warning message, should also be considered:

  • Patients with less common causes of hypokalemia that include Cushing syndrome, Conn’s syndrome and Anorexia nervosa
  • Patients with prolonged gastrointestinal transit time (The amount of glycyrrhetic acid reabsorbed depends on its transit through the small and large intestines, therefore patients with prolonged gastrointestinal transit times are more prone to toxicity after repeated intake)

And I’d add these as factors to consider too:

  • Someone with known high cortisol levels
  • Someone with dietary oxalate issues and/or kidney issues. Licorice tea is listed as low oxalate on the Trying Low Oxalates Facebook group but they will be updating their spreadsheet based on a paper I just shared with them – Oxalate in Foods: Extraction Conditions, Analytical Methods, Occurrence, and Health Implications “Licorice was the highest-oxalate food reported in this review with 3569.3 mg total oxalate/100 g FW (fresh weight).” (this is higher than spinach, sweet potatoes and rhubarb which are really high oxalate)

As with everything, there is no one-size fits all and we need to be diligent about what works for us and what can cause issues.

What are the lasting cardiovascular effects of high blood pressure caused by drinking up to 6 cups of licorice tea a day?

As I shared on the recent licorice-hypertension blog, high blood pressure is one of the many cardiovascular issues with licorice – Beware! Too much licorice tea can cause hypertension even if you have low or normal blood pressure

In that case report, Hypertension induced by liquorice tea, a 45-year-old woman with hot flushes, sweating and headaches, was found to have high blood pressure and low potassium (mild hypokalemia) when she visited her doctor.

She had been drinking up to six cups of liquorice/licorice tea per day and within 2 weeks of stopping this, all her symptoms, the hypertension and the hypokalemia entirely resolved.

This case report is eye-opening because she had always had low blood pressure. I share more about this, my concerns and a very similar incident that I experienced when drinking Throat Calm tea – on the above blog.

What I do want to add is this woman’s concern about possible longer term effects. She says this: “I don’t know if I’ve had any lasting effects on my body by drinking this tea on a daily basis for over a year.” Hopefully her medical team explained much of what I’ve shared here and she was given a thorough cardiovascular work-up.

My cautions for consuming licorice in any form

I am of the opinion that licorice should be treated like the medicinal/therapeutic herb that it is and only be used when working with a knowledgeable practitioner.

This statement in this paper, The cardiovascular complications of licorice, sums up my beliefs:

The health benefits of licorice are minor compared to the adverse outcomes of chronic use which is never justified nor recommended. The long-established belief among the community that licorice is a natural healthy substance free of side effects promotes its liberal consumption and predisposition to toxicity.

I recommend ongoing blood pressure home monitoring if you regularly consume licorice in any form. I also recommend looking at the list of factors that may make you more susceptible to the adverse effects of licorice and discussing these with your practitioner.

I’d also encourage a thorough cardiovascular work-up for anyone who has observed high blood pressure and/or low potassium after consuming licorice for any duration. My blood pressure increased from 110/80 to 137/84 in just a week and it concerned me enough that I went to the doctor to get my potassium checked (it was in range but was only tested 10 days after I quit the licorice tea). I’ll also be discussing all this with my cardiologist and I’ll update this blog when I learn more.

Learning about all this and reading all this research – together with my personal experience and feedback from my community – has been eye-opening to me and hopefully these licorice blogs will help to create more awareness.

Has intake of licorice from tea, candy, herbal products, cough medicines and even smoking cigarettes caught you by surprise?

How much licorice did you consume and over what period?

Did you know about the caution to avoid licorice if you have high blood pressure? What about if you have low blood or normal pressure?

Are you more susceptible to the adverse impacts of licorice intake? And which factors do you suspect played a part if you had issues?

Beware! Too much licorice tea can cause hypertension even if you have low or normal blood pressure

By Trudy Scott 38 Comments

licorice tea and hypertension

A 45-year-old woman presented to her general practitioner with a 4-month history of hot flushes, sweating and headaches. On examination, she was found to be hypertensive, and blood tests revealed mild hypokalaemia [low potassium].

While awaiting the results of further investigation into the cause of her elevated blood pressure, the patient conducted her own research and identified liquorice tea [licorice tea] as the potential cause of her symptoms. The patient had been drinking up to six cups of liquorice tea per day as a substitute for caffeinated tea and fruit-based infusions.

The patient immediately stopped consuming the drink and within 2 weeks her symptoms, hypertension and hypokalaemia, had entirely resolved.

This case report, Hypertension induced by liquorice tea, is eye-opening because this woman had always had low blood pressure and so she ignored the small print on the box that states “not advised for people with hypertension.”

I often see this caution about avoiding licorice if you have high blood pressure (hypertension). But I have yet to see a warning on a box of tea about the fact that licorice can actually cause high blood pressure with high consumption – even when your blood pressure is low or normal. I feel the latter aspect is not as well known, which is the reason for this blog.

I’m also sharing this case report and additional information because something similar has just happened to me (more on my story below).

Here are a few more facts about this patient’s case:

  • She went to her doctor “with a history of hot flushes, night sweats and headaches. These symptoms had started over the preceding 4 months. The patient suspected that her symptoms were due to the onset of menopause.”
  • Initially her blood pressure was 162/82 and “Repeat blood pressure measurement confirmed ongoing hypertension of 150/80 mm Hg”
  • “Blood tests demonstrated mild hypokalaemia” (i.e. low potassium of 3.3 mmol/L).
  • Two weeks after she stopped drinking the licorice tea, “repeat blood pressure measurement was 128/84 mm Hg and her hypokalaemia (and other symptoms) had resolved.”

I encourage you to read the entire published case report to get an understanding of the mechanisms of licorice mediating “its effect on blood pressure via the action of glycyrrhizin on the kidney.” And the impacts on sodium, potassium, aldosterone, cortisol/cortisone and blood pressure. I will add that this is one of many such case reports in the published research.

My story with elevated blood pressure after drinking Yogi Throat Comfort tea

As I mentioned above, I’m sharing this case report because something similar has just happened to me! I had been drinking Yogi Throat Comfort tea for just over a week to soothe my throat and help after my voice loss. It contains licorice root as well as slippery elm and other herbs.

My blood pressure is typically low at 110/80 or less (sometimes as low as 102/80) and last Friday it was 130/80 which is the highest it had ever been.

I didn’t make the connection to licorice right away because I had just flown internationally from Hawaii to Australia and we were sprayed with insecticide on the plane when we landed in Australia. We all had to sit there in the toxic soup for 10 minutes. (I’ll be sharing more about all this in a future blog).

I suffered severe vertigo the next day and it was at the doctor’s office that I found out my blood pressure was 130/80. I was very surprised but he felt it could be due to the travel or vertigo or voice issues. I also know that bereavement can have major physiological impacts and increased blood pressure is one of them (I was in Hawaii for my darling mom’s memorial).

I finally made the connection when my blood pressure measured 137/84 a few days later and stopped drinking the tea immediately. Over the next few days it came down to 127/93 and then 121/90 and then 118/84.  I expect it to continue to come back down to my normal low blood pressure and will update this blog when it does.

As far as symptoms, I was just not feeling myself and had a strange feeling of apprehension, spaciness and breathlessness when talking too much. These are much improved having stopped the tea. My naturopath also recommended eating a banana each day to increase my potassium levels and to have epsom salt baths to help regulate the electrolytes in my body.

I will admit there are the above confounding/contributing factors – grief, voice loss, travel, vertigo, insecticide exposure – so I can’t be sure it’s only the licorice in the tea, and I’m not willing to test it out right now.

(Update Oct 13, 2023:  A week later and it’s now pretty much back to my usual low blood pressure. Over the course of this last week it measured 125/82, 118/91, 127/84, 118/85 and today it’s 112/85. I will continue to track.)

How much licorice tea is too much?

The authors of the above case report mention this about the dose of glycyrrhizin:

  • Experimental studies have shown that the rise in blood pressure caused by liquorice follows a linear dose–response relationship. Doses of as little as 75 mg of glycyrrhizin (equivalent to 50 g of standard liquorice confectionery) given daily for a 2-week period have been shown to cause a significant increase in systolic blood pressure (the first number).
  • In a survey of 33 brands of liquorice tea, the mean glycyrrhizin content was found to be 126 mg/L (range 2–450 mg/L). A cup of liquorice tea with a volume of 250 mL could therefore be expected to contain, on average, approximately 31.5 mg of glycyrrhizin.”
  • The European Scientific Committee on Food advises that regular glycyrrhizin doses of 100 mg/day present a risk to health, and advocate a safe average daily intake of no more than 10 mg/person/day. This is an amount equivalent to less than half a cup of liquorice tea or just 6 g of liquorice confectionery daily.

In the above published case, the patient had been “averaging around 4–6 cups per day, and had been consuming the licorice tea for about a year.” She was “unwittingly consuming daily volumes of liquorice tea containing up to 190 mg of glycyrrhizin, well in excess of the recommended limit” of 10 mg per day. It was 8 months before she started to notice the adverse effects, but I do wonder how long she had high blood pressure.

We have a home blood pressure monitor but I haven’t used it for ages and if I hadn’t gone in to the doctor for my vertigo, my elevated blood pressure may have gone unnoticed for a while too.

How much did I consume: a total of 10 Yogi Throat Comfort tea bags over the course of a week. The day before leaving I had a few cups of hot tea and was thrilled to be able to talk on my last day there.  I then drank it all day on the 15+ hour flight back: I had 2 tea bags in my 2 liter / 2 quart water bottle and filled it up a few times with cold water.  And I continued to do this once I was home, having it next to my bed if I woke up coughing in the night. I was probably getting 3 or 4 times more than the safe average daily intake of 10 mg/person/day.

I love licorice tea and drink it from time to time, maybe 2-4 cups a month. I’m quite surprised it affected me so quickly but have never consumed this amount and in such a concentrated time period.

Will I drink Yogi Throat Comfort tea or other herbal teas that contain licorice?

For now, I think I will – the Throat Comfort tea helped so much with my voice – but when I do I will monitor my blood pressure carefully and then make a final decision.

I also plan to dig a bit further into some of the confounding factors I mention above to see how they could possibly have made me more susceptible.

I do also have dietary oxalate issues so this could play into the effects of glycyrrhizin on the kidney. I’m finding mixed results on the oxalate content of licorice: some papers say high and some say low. But I didn’t have any of my typical oxalate reactions such as painful feet or eyes. I have, however, noticed some stiffness in my left hip the last few days so will be looking further into this aspect.

(Update Oct 13, 2023: Licorice tea is listed as low oxalate on the Trying Low Oxalates Facebook group but they will be updating their spreadsheet based on a paper I just shared with them – Oxalate in Foods: Extraction Conditions, Analytical Methods, Occurrence, and Health Implications “Licorice was the highest-oxalate food reported in this review with 3569.3 mg total oxalate/100 g FW (fresh weight).” (this is higher than spinach, sweet potatoes and rhubarb which are really high oxalate)

My takeaway messages – a warning and listen to your body

There is no licorice hypertension warning on this Yogi Throat Comfort tea box (or my Tulsi Licorice tea) and I do feel there should be 2 warnings: the usual warning about licorice if you have high blood pressure AND a general warning that licorice may also affect you if you have low or normal blood pressure.

My other takeaway message is this: listen to your body and get checked out when things don’t seem as they should be.

Has something like this happened to you? How much licorice tea did you consume, which brand and over what period?

Do you typically have low blood pressure and were you also caught by surprise?

Did you know about the caution to avoid licorice if you have high blood pressure?

And what about the fact that licorice may also affect you if you have low or normal blood pressure?
