Histidine is an essential amino acid that gives rise to histamine, a substance that regulates the body's inflammatory responses. When histidine is used to treat allergies it should be taken as a supplement in portions that can vary between 100 to 150 mg per day, and which are prescribed by the doctor.
When the fish is not properly preserved, histidine is transformed into histamine by bacteria, causing the fish to have high amounts of histamine, which can cause poisoning in humans.
