None

Storage method

Seal and store in a cool place away from light.

Synthesis method

Can be produced by decarboxylation of histidine.

Purpose

It can cause smooth muscle spasm, capillary dilation, and increased permeability. In allergic diseases, there may be a release of histamine or similar substances in the body. In medical treatment, it is mainly used to promote gastric acid secretion to check the secretory function of the stomach.
