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: arrow poison use, 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. Some have caused accidental deaths, while some have been used with suicidal or homicidal intent.

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.
