Aconitine (from Aconitum species)

Aconitine is a potent toxin found in Aconitum plants, also known as monkshood or wolfsbane. It affects the nervous system by disrupting sodium channels in nerve cells, leading to symptoms like numbness, weakness, and potentially dangerous heart rhythm problems. While historically used in traditional medicine, it is highly toxic and can be deadly if ingested or improperly handled. Its potency means it should be treated with extreme caution and is generally considered a hazardous substance rather than a medicinal one.
