Salicylate sensitivity doesn’t get as much attention as histamine intolerance or oxalates — but for some people, it’s the missing piece of the puzzle.
If you’ve been dealing with vague symptoms like rashes, sinus congestion, headaches, or food reactions that don’t quite make sense, salicylates could be playing a role. These natural compounds show up in healthy foods like fruits, herbs, and spices, but in sensitive individuals, they can trigger a surprisingly wide range of symptoms.
In this article, we’ll explore what salicylates are, how to recognise signs of a sensitivity, and two key strategies I use in clinic to assess and support patients who may be reacting to them.
What Are Salicylates?
Salicylates are natural chemical compounds produced by plants as a defence mechanism. They help protect against bacteria, fungi, and environmental stress — which is great for the plant, but not always so great for sensitive humans.
These compounds are found in a wide range of healthy, everyday foods — especially fruits, herbs, and spices — and that’s part of what makes salicylate intolerance so tricky to spot. You could be reacting to foods that are generally considered anti-inflammatory and nutrient-dense.
They are found in a range of foods and herbs in differing levels. Top of the list here would be
There are many more, but this list covers the heavy hitters I see trigger reactions most often in clinic.
If you’ve ever felt worse after eating a big Mediterranean-style salad, or noticed flares after coconut yoghurt or spicy dishes, salicylates might be worth investigating.
Salicylates are natural plant compounds that show up in a surprising number of everyday foods, especially fruits, herbs, spices, and oils. While they’re usually seen as healthy, they can cause problems for people who are sensitive to them.
What Does Salicylate Intolerance Feel Like?
Salicylate intolerance doesn’t always present in obvious ways. The symptoms can feel random, vague, and frustratingly disconnected — which is why many people go years without realising salicylates are part of the picture.
Some of the most common symptoms I see in clinic include:
These symptoms often overlap with histamine intolerance, which can make it tricky to tease apart the root cause. If you’re unsure where salicylates end and histamine begins, this article breaks down how histamine impacts digestion.
Here you can see strong overlaps with other food triggers so testing for salicylate intolerance is key. I recommend the Great Plains (aka mosaic) Organic Acid Test to patients all the time in the Byron Herbalist clinic. See here for more information on working together.
Candida is a common underlying driver of salicylate intolerance, but it can be notoriously difficult to detect. I often use the Organic Acids Test (OAT) in clinic to help rule it in or out. There are also two other commonly used tests for Candida, which you can explore in more detail here.
Beyond the OAT test (image below) I haven’t found a great way to test for salicylate intolerance. From here we go with the treatment being the test which is equally as helpful. How much better do you feel when we restrict salicylates and treat with some approaches below.
Salicylate Treatment Approach #1: Urinary pH Testing
One of the simplest ways to assess your ability to clear salicylates is by tracking your urinary pH. It might sound basic, but it gives real clues about how well your kidneys are handling these compounds.
For your body to effectively eliminate salicylates, the urine needs to be slightly alkaline. If your pH is too low (acidic), you may end up reabsorbing salicylates instead of excreting them — which I often describe to patients as “re-toxifying yourself.”
How to test urinary pH at home:
If your urine is consistently below that, it may be a sign that your body can’t effectively eliminate oxalates well and symptoms can start to build.
In those cases, I often recommend alkalising mineral support. Magnesium, potassium, calcium, and sodium bound to citrate (not oxide or carbonate) can gently nudge pH upward and support detoxification without being aggressive.
Urinary pH below 6.5 can make it harder to eliminate salicylates. Testing at home with pH strips is a simple first step. If you’re consistently acidic, adding citrate-bound minerals can support clearance and reduce symptoms.
Salicylate Treatment Approach #2: Support the Sulphate Pathway
Another essential evaluation for salicylate intolerance and support revolves around the sulphate (or sulfate) metabolism pathway. Adequate sulphate levels in the body are required to power the phenyl sulfur transferase enzyme, which detoxifies phenols and salicylates. While direct testing for sulphate levels is challenging, a promising approach involves optimising sulphate availability through methods like Epsom salt baths. You can get these at an affordable price online as I like to dose high (as tolerated) and work back.
This approach involves a strong Epsom salt bath (up to four cups of magnesium sulphate) in hot water for approximately 10-15 minutes each night for a week. Epsom salt baths provide sulphate that can support the enzyme’s function, aiding the detoxification of salicylates. It’s important to start slowly and gradually increase the frequency and duration of Epsom salt baths, especially for individuals who are sensitive to changes.
Another Angle to Salicylate Intolerance
While salicylate intolerance presents with diverse symptoms and challenges, there are practical and effective ways to manage the condition.
Initially testing using the Great Plains OAT test then moving onto evaluating urinary pH and optimising sulphate metabolism which can significantly improve the body’s ability to process and eliminate salicylates. These evaluations, combined with addressing underlying factors like microbial imbalances, nutrient deficiencies and metabolic stress, can offer a comprehensive approach to managing salicylate intolerance.
Remember everyones response to these recommendations may vary, and a personalised approach, guided by healthcare professionals, is essential.

Hi my son is 10 yr old he is having lots of food reactions one of the symptom is bed wetting and asthma he is salicylate intolerant we have done testing
Hi Aaron, which test have you done for salicylate intolerance please? Thanks
I would bet anything you are living in mold, even if unseen. Get the house tested using an ERMI test. Every one of his symptoms are triggered by mold. Especially the bedwetting and asthma. The food sensitivities too, b/c the mold affects the gut or he is already developing mast cell activation, which can also cause the food sensitivities and the salicylate sensitivity. I have MCAS and salicylate sensitivity (along with 100 other issues now) and my daughter had the regression into night time bedwetting. I was a neat freak and missed hidden mold. Took 5 inspectors and several tests to find it. Good Luck.
Hi there thanks for sharing Im in the same boat difficult to find a safe place when you’re so sensitive to everything..what as helped you so far if you don’t mind sharing
Hi byron, does taking calcium D- glucarate help with salicylate intolerance? thank you
Does glycine help ? What if I feel the vegetable cellulose is a problem? I’ve been dismissed for 4 years and now I can’t tolerate anything plant related –
Look into Mast cell activation syndrome and make sure you are not living in mold. You need to test the home using an ERMI dust sample. I lost all of my food except chicken and carrots at one point and plants were the worst for me. If you are sensitive to all plants, you are probably also having an issue with oxalates and lectins, which many mast cell patients struggle with. Mast cell is most generally triggered by mold.
Hi Nicole My husband is chronic with salycilate intolerance, very severe. He tried Glycine and it seemed to make him feel so much better. The nasty side effect was horrendous breath. I couldn’t sit too close to him at all. In the end he gave it up.
Hi, thank you for this insightful article. I am salicylate intolerant and I am affected severely by some foods more than others. I will be 40 years this year but I’ve realized that some of the symptoms that I’ve experienced for years, such as eczema and bed wetting as a child, swelling of the fingers, rhinitis, tinnitus and panic attacks, confirm that I’ve had this for quite some time. I’m going to send this article to my health care provider to see if the approaches that you mentioned can be used to help me. Thank you again
No problem! Glad it was helpful :-)
You need to look into WHY you have the intolerance. Your symptoms also describe mold toxicity to a tee, which is a major trigger for food intolerances. I have salicylate, lectin and oxalate intolerance along with histamine intolerance all starting AFTER major mold exposure but had probably been exposed early in life and struggling unknowingly throughout my entire life. I have or have had every single one of your symptoms. This indicates an issue detoxifying mold, which can also have a genetic cause. Treat the root cause (mold) and you can get rid of or significantly minimize all of the intolerances. Definitely related to detox pathways which can get clogged by mold, thus increasing issues with food. Probably have complete gut health destruction too, which mold is good at. Good Luck.
ESF, I agree with you 100%. Mold is a phenol, salicylates are a type of phenol. And those who are the sickest from mold exposure and illness develope salicylate intolerance as well as phenol intolerance, so herbal treatments are not an option until this can be resolved (not easy to do).. And we are often those who are most the difficult to treat as often practitioners don’t know what to do with us. sals/phenol intolerance isn’t studied as in-depth as say histamine, Sals, phenols and mold are all detoxified via the same glucuronidation & sulphur pathways, which are plugged up with toxic metabolites and overload due to impact mold causes the body. Oxalates & sulphur intolerance join the spiral as well as many other intolerances.
I also totally agree about the link between mould sensitivity & salicylate intolerance (as well as histamine, oxalate issues). I thought I had the salicylate problem under control and could tolerate a lot more, until I got exposed to black mould again and it set me back completely. Some of the things that help me (along with a low salicylate diet obviously) – activated bamboo charcoal capsules, dandelion root tincture, slippery elm. In case that’s useful to anyone.
Many thanks to Byron Herbalist for the article, I will look into the alkalising minerals
My name is Steven I’m 26 years old, I have a salisylate intolerance, how do I calm down a reaction if I consumed something with, the many things I like eating is fish,eggs,bread and meat, but I wanna avoid eating things like tomatoes, apples, plums, cherries, or any other type of fruit, I can only have bananas and pears. (Peeled), is fish oil, a good remedy, stopping a salisylate reaction?
Hi Steven, thanks for the input. I haven’t seen fish oil to be particularly helpful for dealing with a salicylate intolerance. Treat any gut imbalances in the small bowel, improve detox substrates (sulphur mainly) and alkalise the urine if necessary too.
I just found this trial where people pre-medicated with Capsaicin pills before ingesting Salicylate-containing foods and they had no adverse effects.
The capsaicin dose they used only worked to counteract the effects of Moderate and High Salicylate foods, but not Very High.

I found on the Internet that salicylate is sensitive due to a malfunction of the second phase of liver detoxification. Grapefruit juice, cigarettes (tobacco), pomegranate juice, turmeric accelerate this process. I smoke and there are no problems.
You mean these help detox the second phase?
Is it proven that Calcium D-Glucerate is effective to reduce and help to eliminate salicylate in our body?
What if we are sulfur intolerant as well
