Anyone who tries to post scientific literature gets an A+ in my book. Even if it's not dead on, it means SO much more to some people then anecdotal hulabaloo. Sorry to derail this further but I selfishly wanted to reward elusivemind

Hahaha, many thanks Mydriasis.
So I finally had some more free time and did more searching and "reading/trying-to-understand" of different papers around the web. It seems when searching for anything relating to the tumor or irritant properties of the root, the papers always refer to the first paper I posted on this topic. So I looked a little deeper into that paper and others... and these are my findings... (in no particular order)
- The neurotrophic compound in Kirkii is kirkinine. In the articles that I have read, the finished extraction from the Kirkii plant was a colourless gum (Paper 1, page 1)
- "Compounds with neurotrophic activity are known, but kirkinine is remarkable for its potency and structural diversity when compared with all other compounds endowed with NGF-like activity described so far" (Paper 1, page 2) AKA should have a lot more attention then it currently does
- Gnidimacrin is the anti-leukemic compound in the plant roots. Approximate isolation results are 0.0005% (no reference to isolation number). (Link 1)
-Kirkinine isolation was approxamitly 0.00002%. (again no reference to isolation number) (Link 1)
- "Previous studies led to the isolation of numerous phorbol and related esters, some of which showed powerful skin irritancy as well as antineoplastic and immunostimulating activities." (Paper 1, page 1) Still looking into which compounds are responsible for the tumor growth and now the antineoplastic (cancer fighting) and immunostimlating activities (stimulates the immune system, like Maitake mushrooms

)
SIDE NOTE:
- As I was looking into it more it seems that "9,13,14-ortho-(2-hexadecenoate)" and the "12
B-acetoxy derivative of 9,13,14-ortho-(2-hexadecenoate)" are the most potent tumor promotors from the 1a-Alkyldaphnane type of DTE (Diterpene Esters) isolated, and "9,13,14-ortho-(2E-hexadecenoate)" was the most potent from the Daphnane type DTE isolates. Just throwing this information up there to see if any SWIMmers can help verify this and maybe help find more information on these DTE's.
I found this information in the first paper I posted on this topic on page 8 under the italicize heading "Tumor promoting activity -structure/activity relations"
So that is the information I have been able to find so far. But with the little known information on the tumor and irritant properties and being that it IS sold at multi stores, etc as Phlux stated, its looking more like they are extremely low concentrations in the root.
