Histamine

Histamine, also known as histaminum or eramin, belongs to the class of organic compounds known as 2-arylethylamines. These are primary amines that have the general formula RCCNH2, where R is an organic group. Histamine is a very strong basic compound (based on its pKa). Histamine exists in all living species, ranging from bacteria to humans. This can lead to three clinical responses:sneezing due to histamine-associated sensory neural stimulationhyper-secretion from glandular tissuenasal congestion due to vascular engorgement associated with vasodilation and increased capillary permeability Sleep-wake regulation Histamine is a neurotransmitter that is released from histaminergic neurons which project out of the mammalian hypothalamus. Within humans, histamine participates in a number of enzymatic reactions. In particular, histamine can be converted into histamine; which is catalyzed by the enzyme histamine H2 receptor. In addition, histamine can be converted into histamine; which is catalyzed by the enzyme histamine H2 receptor. In humans, histamine is involved in intracellular signalling through histamine H2 receptor and histamine. Histamine is a potentially toxic compound. Histamine is expected to be in Cannabis as all living plants are known to produce and metabolize it.
