In Latin America, found primarily in second growth forests, species of
Croton are used for all kinds of stuff. I don't have a reference for C.
tiglium, but I do know that C. lechleri is a tree that has potent
antifungal/antiviral properties. A drop of the sap (reddish-bronze) is
put on the skin and rubbed...it foams into a lather and seems to do the
trick on infamous "jungle rot". It is also a common ingredient in soaps
for such a purpose.
Other species, C. persicaria have had morphine-like alkaloids (Tiwari,
1981),; Schultes and Raffauf found that the Witoto Indians of Columbia
use the leaves of C. glabellus for eczema-like symptoms...
All kinds of stuff...but I don't know anything about C. tiglium or if its
sap will promote tumor growth.
