Studies
Tumor Promoter Activity:
In a Malaya study for long-term side-effects of herbal medications, 48 species of Euphorbiaceae were screened for tumor-promoter activity using a human lymphoblastoid cell line harboring the EBV genome. 27% (13/48) were found to be positive, and four, including E atoto, were found to have EBV-induciing activity at low concentrations in cell culture. The observation warrants study for an etiologic factor for the promotionn of tumors among rural Malaysian Malays.
