Histamine has an additive effect on estrogen, which can raise estrogen levels (think heavy periods, endometriosis, migraines). When your estrogen levels are high, mast cells are stimulated to release more histamine.
Estrogens promote the degranulation of mast cell/basophils
The release of the major mediators of acute hypersensitivity (e.g. histamine, cysteinyl leukotrienes) is an obligatory event in allergic reactions.
The interaction between estrogen and histamine goes both ways: Histamine has an additive effect on estrogen, which can raise estrogen levels (think heavy periods, endometriosis, migraines). When your estrogen levels are high, mast cells are stimulated to release more histamine.
In theory cortisol contributes to lowering histamine levels, but in those cases where adrenals have been working hard for an extended period of time, as is the case with many people with an autism diagnosis, cortisol levels tend to be low and so CRH stays high, contributing to releasing inflammatory cytokines such as ...
Histamine intolerance is more common in people with underlying digestive issues. Conditions such as inflammatory bowel disease, celiac disease, IBS, and SIBO increase the risk of histamine intolerance. There is minimal information on the actual incidence of HIT. Its correlation with other health issues is emerging.
Drinking plenty of water every day is essential for all bodily functions, including the regulation of histamine levels. Water does aid in the removal of histamines from the body as more that 95% of excess histamines are removed from the body through the urine.
If you're experiencing a histamine reaction, try chewing on fresh ginger or pouring boiling hot water over sliced ginger to make fresh ginger tea. In general, you can also drink ginger tea before bed to act as a natural antihistamine and prevent histamine reactions.
Vitamin C is a natural antihistamine, which means it can lower histamine levels and mitigate allergic reactions and symptoms. Consume plenty of Vitamin C rich foods, like tropical fruits, citrus fruits, broccoli and cauliflower, and berries.
Claritin and Zyrtec are effective and safe for most people with minor allergies.
Natural antihistamines may help you control your seasonal allergies. Common ones are stinging nettle, vitamin C, quercetin, butterbur, bromelain, and probiotics. Some alternative practices—such as acupuncture, nasal irrigation, and exercise—may also help you manage symptoms.
Degradation of histamine in gut. (A) Healthy individual. Normal concentration of histamine in food. Most histamine is inactivated by DAO and HNMT enzymes in gut, only a small amount of histamine passes to blood stream and does not cause histamine-mediated symptoms.
Studies suggest that vitamin B12 can trigger histamine release in the body. Certain bacteria or yeasts can convert histidine into histamine in the body, triggering an allergic reaction. Fermented foods high in certain types of microorganisms can trigger a histamine allergy in the body.
Histamine intolerance (HIT) is assumed to be due to a deficiency of the gastrointestinal (GI) enzyme diamine oxidase (DAO) and, therefore, the food component histamine not being degraded and/or absorbed properly within the GI tract.
MCAS (mast cell activation syndrome) You often hear histamine intolerance and mast cell activation syndrome or MCAS used together or even interchangeably.
These include: Flushing, difficulty regulating body temperature, sudden excessive sweating. Hives, rashes, swelling, itchy skin, eczema. Racing heart, palpitations, arrhythmia.
Boswellia, also known as frankincense, is a potent anti-inflammatory herbal medicine that can help to stabalise mast cells and reduce histamine load in the body.

Coffee contains histamines in low amounts, but for people who are sensitive to them, it contains plenty to get a reaction out of them. While the natural histamine content in coffee is low, some coffee processes can increase histamine levels.
Vitamin C: lowers the histamine level in the blood. Vitamin B6: is an important co-factor of the enzyme diamine oxidase and its activity. Calcium: reduces the development of wheals and flushing of the skin. Zinc: has anti-allergic and anti-inflammatory properties and constrains histamine release.
