Bufotoxin

Bufotoxins are a family of toxic substances found in the parotoid glands, skin and venom of many toads (genus Bufo); other amphibians; and some plants and mushrooms. The exact composition varies greatly with the specific source of the toxin. It can contain: 5-MeO-DMT, bufagins, bufotalin, bufotenine, bufothionine, epinephrine, norepinephrine, and serotonin. The term bufotoxin can also be used specifically to describe the conjugate of a bufagin with suberylargine.

The toxic substances found in toads can be divided by chemical structure in two groups:

• bufadienolids which are steroidal glycosides (e.g. bufotaline, bufogenine)
• tryptamine related substances (e.g. bufotenine)

Extract from the skin of certain Asian toads, such as Bufo gargarizans, is often found in certain Chinese folk remedies.
