5. Potentially Prevents CancerBased on castor oil’s effect on the lymph system, many researchers are interested in how this natural remedy influences certain cancers. Although more research needs to be conducted, it appears that castor oil can inhibit tumor growth. Within one study, published in the International Journal of Toxicology, castor oil extracts were shown to actually suppress tumors in mice.
Researchers found a similar effect when studying castor extract in relation to melanoma, as apoptosis (or death) was observed in cancer cells. Researchers have documented these effects while studying colon, prostate, ovarian and breast cancer cases as well.
