Apart from those plant sources which have already been researched and proven to be effective when used with differing compounds to treat many forms of illness - like for instance the one that
Zigs has mentioned Taxol which is now widely used in cancer treatments - there are many. many plant substances as well as herbs that have as yet not been thoroughly researched and proven to be effective.
Which as they haven't yet been fully researched and there is as yet no conclusive scientific evidence to say whether any are effective in treating certain medical conditions - maybe some of those would be of interest to you - as there are many to choose from.
Like for instance the two that have already been mentioned - especially as - although there has been quite a bit of research into garlic and some studies have shown that Garlic may possibly be effective in lowering blood pressure and maybe even help in fighting fungal infections of the skin - there is still a lot more research needed - as there is as yet no conclusive evidence to support any of those claims - as one of the major concerns are the side effects - with the main one being - that as garlic is known to thin the blood - it puts patients at risk and particularly those undergoing surgery as well as those taking heart medications and anticoagulants.
Turmeric or Curcumin on the other hand might be a particularly good choice as a leading edge research project - mainly because - as of yet - their is no conclusive evidence to say whether or not Turmeric may be an anticancer agent or in fact have any other medical uses either.
Due to the fact research into Turmeric and Curcumin for cancer prevention and treatment as well as other medical uses - has only just begun and is therefore still in the very early stages of development and as all the scientific studies so far have found - that it does not absorb well from the intestine and that very large doses are required just to get small amounts into the blood stream - as a great deal more research is needed in order to ascertain what role, if any, turmeric and curcumin may play in the prevention or treatment of cancer.
Maybe researching curcumin or turmeric and making some ground breaking discoveries - might be just the kind of research you are looking for
