Mescaline Mexico. Europeans noted use of peyote in Native American religious ceremonies upon early contact, notably by the Huichols in Mexico. Other mescaline-containing cacti such as the San Pedro have a long history of use in South America, from Peru to Ecuador. In traditional peyote preparations, the top of the cactus is cut off, leaving the large tap root along with a ring of green photosynthesizing area to grow new heads. These heads are then dried to make disc-shaped buttons. Buttons are chewed to produce the effects or soaked in water to drink. However, the taste of the cactus is bitter,
Sodium fluoroacetate brand name. The salt is synthesized by treating sodium chloroacetate with potassium fluoride. Potassium fluoroacetate (as opposed to the commercially manufactured sodium salt) occurs naturally in at least 40 plant species in Australia, Brazil, and Africa. It was first identified in "Dichapetalum cymosum", commonly known as gifblaar (Afrikaans) or poison leaf, by Marais in 1944. As early as 1904, colonists in Sierra Leone used extracts of "Chailletia toxicaria", which also contains fluoroacetic acid or its salts, to poison rats. Several native Australian plant genera contain the toxin, including "Gastrolobium", "Gompholobium", "Oxylobium", "Nemcia", and "Acacia". "Gastrolobium" is a genus of flowering
