Strychnine (nux vomica)

Tier 4 — risky / avoid · Neurotoxin · Fatal seizures

Nux vomica seeds contain strychnine, one of the most potent convulsant poisons known. It causes uncontrollable muscle spasms and seizures that can lead to respiratory failure and death. Despite this, it is still found in some homeopathic and traditional medicine products, sometimes at concentrations high enough to cause poisoning. The lethal dose in humans is approximately 30 to 120 mg. There is absolutely no legitimate supplement use.

Dose: AVOID completely; strychnine causes fatal seizures; lethal dose is 30–120 mg; no safe supplement use
