Well, I found one of thing things I was looking for.

This should be the translation of a study that attempted to determine if Carao (an anemia cure) was toxic to rats. The conclusion was that 2000mg/kg was not toxic.

I could tease you and tell you about the huge weight gain seen by the rats, but for some reason between day 1 and 7 all rats, control (no Carao) and the 3 types of extract all gained similar weight.
Also, it looked to me like the liver of the Carao treated rats (both male and female) showed a statistically significant increase in weight for 2/3 Carao groups. This subset of the data is not viewed as a positive thing by me, but the authors of the study declared all is well so as a whole the study is viewed by me as good news.
This tree Cassia Grandis POTENTIALLY has a lot of uses. Leaves have been used for a tea to help with diabetes (some claimed a diabetes cure, but I think it is a treatment). As I read this if you wish you can dilute your extract and rub it on your body to cure ring worm. The leaves can be used for an ointment that could potentially even effect herpes (positively).
This tree is not just found in Costa Rica. I am fairly certain when I lived in Hawaii I played with the seed pods of this very tree (but I do not remember in flowering pink). It seems it is in a number of fairly warm and humid climates.
I am certain that I have been over paranoid, but I do not believe everything the FFDA says I can put in my body will not hurt me (and everything the FFDA says will hurt me actually will).
Enjoy, TOm
