But the case is different with cocculus indicus, and stramonium, and sulphuric acid, and sugar of lead, and the like. I take the following accounts, so far as they are medical, from a standard work by Dr. Dunglison: Aloes is a cathartic. Cocculus indicus contains picrotoxin, which is an "acrid narcotic poison;" from five to ten grains will kill a strong dog.
Ether from the acid solution dissolves out colchicin, digitalin, cantharidin, and picrotoxin, and traces of veratrine and atropine. Separate the ethereal solution and evaporate. Hot water will now dissolve out picrotoxin, colchicin, and digitalin, but not cantharidin.
Deepened colour and dense white fumes with nitric acid. Pale red, deepening, with hydrochloric acid. There are several other umbelliferous plants which are poisonous. It contains an active principle, cicutoxin, which in some respects is allied to strychnine and picrotoxin.
Contains a poisonous active principle, picrotoxin; used to adulterate beer, and by poachers to stupefy fish. Symptoms. Convulsions, followed by stupor and complete loss of voluntary power. Symptoms. Gastric symptoms and marked jaundice. This may be followed in days or weeks by stupor, coma, death. Post-Mortem. Fatty degeneration of internal organs, chiefly liver. Symptoms.
