Joseph S. Karas, Common poisonous plants of New England (1964)
“ Leaves and seeds contain smaller quantities and can be harmful. Poisoning is characterized by salivation, abdominal pain, and attempts to vomit. Large quantities produce a cold and clammy skin and depressed circulation due to effects of veratrum alkaloids on the heart muscles and on respiration. Death may result.Antidote: Call your doctor. Have patient vomit if the victim has not become unconscious and appears calm. If shock has developed, use standard first aid measures. Physicians treat for veratrum alkaloid poisoning. ”
