Histamine

Definition of Histamine:

A chemical in the body tissues, produced by the breakdown of histidine.  It is released in allergic reactions and causes widening of capillaries, decreased blood pressure, increased release of gastric juice, fluid leakage forming itchy skin and hives, and tightening of smooth muscles of the bronchial tube and uterus.  Histamine is the chemical that drives the initial acute allergic reaction, causing itching, swelling and congestion.

“Doctors using MSM agree that patients who have used antacids and histamine receptor antagonists to control hyperacidity can employ MSM with good results.”

Histadelia (Histamine High)

...our question about Level of motivation
“Those with elevated histamine (histadelics) tend to work compulsively.”
...recommendation against Folic Acid
“Histadelics should avoid supplemental folic acid as it can produce excess histamine.  In fact, anti-folate drugs may be required...”
...recommendation Methionine
“Methionine supplements lower blood levels of histamine by increasing histamine breakdown.”
...recommendation Copper
“...Copper is part of the enzyme histaminase, which is involved in the metabolism of histamine.”
...recommendation Plant-Based Nutrition
“...Histidine, which is more common in animal proteins, should be avoided as it can be converted into histamine.”

Histamine Therapy

...as a treatment
“...The strategy of administering small doses of histamine is meant to balance out the parts of the immune system that stimulates allergies or auto-immunity, and the parts of the immune system that keep the allergic or autoimmune reactions under...”

Histapenia (Histamine Low)

...the condition
“...Since copper is a brain stimulant and destroys histamine, the elevated serum (and presumably brain) copper level probably accounts for many symptoms, including the low blood histamine level...”
...our question about Childhood hyperactivity
“Low histamine children are hyperactive while often healthy in other respects.”
...recommendation Zinc
“...Zinc and manganese allow for the normal storage of histamine in both basophils and the brain...”
...recommendation Vitamin C (Ascorbic Acid)
“...Copper destroys histamine and therefore as copper levels decrease, histamine levels should return towards normal.”
...recommendation Folic Acid
“The rationale underlying this treatment is that folic acid in conjunction with vitamin B12 injections raises the blood histamine while lowering the degree of symptoms.”
