Plants with Known Toxicity

List of toxic plants

This is a list in progress, far from complete, added on as I do the updating of the medicinal plants for scientifc studies. While some are known in the rural grapevine for their toxicity, many, surprisingly, are not. The toxicities are quite varied: fish poison and arrow poison uses, abortifacient properties. hallucinogenic effects, liver, renal, and other organ toxicities. Many have short-term gastrointestinal effects. Some toxicities are dose-dependent; some are toxic simply because of over-consumption of certain plant parts. Sometimes toxicity is brought about by herb-drug interactions. Fruits may be toxic when unripe, but safeky edible when ripe. Some have caused accidental deaths, while some have been used with suicidal or homicidal intent.

Patients may be well-advised to discuss their alternative herbal plant regimens with their physicians. But, alas, there never enough time for this in the hurried consultations.

New plant names needed The compilation now contain more than 1,100 medicinal plants.The last 100 plants came with great difficulty, many by happenstance, a few contributed to or suggested by site visitors. I believe there are hundreds more that can be added to this compilation. Please send suggestions for inclusion with as much of the following information: local plant name, scientific name, known folkloric medicinal use, and a photo.
