There are about 30 species of Veratrum. Some of the most well-known include:

Uses

Historically, Veratrum species have been used medicinally for their emetic, cathartic, and narcotic properties. However, due to their high toxicity, they are rarely used today except in homeopathy.

Toxicity

All parts of the plant are poisonous, containing steroidal alkaloids such as veratridine and cevadine that affect the nervous system. Symptoms of poisoning include nausea, vomiting, abdominal pain, headache, and death in severe cases.

Etymology
