Croton glabellus has been reported to be alkaloid-positive 
(Haynes, L. J. et K. L. Stuart: Journ. Chem. Soc. 1963 (1963) 
1784, 1789). The genus appears to be relatively well furnished 
with alkaloids (Raffauf: loc. cit. (1970); Gibbs: loc. cit. 3 (1974) 
1353, 1359).

The sap of this tree is applied to ulcers and boils to reduce pain. 
Euphorbia sp. 
Amongst the Kofans, the latex of this Euphorbia is put into 
infected cracks in the skin on the bottom of the feet—an 
infection caused probably by fungal organisms. The Kofan name 
is shi-vak-o-sehe ’-pa (H. V. Pinkley 42, cited in Pinkley: The 
Ethnobotany of the Kofan Indians. Unpublished Ph.D. thesis, 
Harvard University (1973) 217).

According to Kubeo informants, the oil extracted from the 
seeds was in former times rubbed into the scalp to prevent or 
delay loss of hair. 
The genus Mabea has not been chemically investigated.
