"Poisonous" does not mean deadly. Some manifestations of toxicity are subtle. The dose, as always, determines if a plant is safe source of nutrients or a toxic hazard.

BRIEF: Can you help me find information on these plants?

I am doing a class research project on medicinal plants and I am having difficulties finding some information. Would you happen to know about or know where I might find information on the following plants: stemmadenia litoralis, spp, Ixora Coccinea (nora grant), houttaynia cordata. Thank you for any information you might have.


I don't know much of those plants, so I would try a trip to the library. If these Latin names are not current, you won't find them on line... I think Ixora coccinea is used as an ornamental down South, so check with a Florida source Stemmadenia litoralis is in the Apocynaceae, so it might have some toxic cardiac glycosides, many of them do...and it may have the ibogaine type material in it that other members of that genus have..these compounds have been suggested for both treating drug abuse and as possible drugs of recreation...Make your window wide for this one... 14. Obovamine, a New Indole Alkaloid from Stemmadenia Obovata. Madinaveitia, A., Reina, M., Delafuente, G., Gonzalez, A.G. and Valencia, E. J NAT. PROD. 59:185-189, 1996. Abstract: The stem bark of the Panamanian plant Stemmademia obovata has afforded a new ibogaine-type alkaloid, obovamine (1), whose structure was determined by a combination of spectral interpretation and chemical correlations. Ten known alkaloids, coronaridine, coronaridine hydroxyindolenine, voacangine, voacangine hydroxyindolenine, (19S)-heyneanine, (19S)-heyneanine hydroxyindolenine, (19S)-voacristine, (19S)-voacristine hydroxyindolenine, ajmalicine, and ajmalicinine, were also isolated. Voacangine was the main alkaloid constituent Houttaynia cordata? Don't know anthing about this one.
