Another recent study compared the effect of Tualang honey with that of the pharmaceutical tamoxifen (an estrogen receptor antagonist) in two breast cancer cell lines (MCF-7 and MDA-MB-231). The study found that the anti-cancer effect of tualang honey on breast cancer cells was comparable to that of tamoxifen, a multi-billion dollar blockbuster drug. This is all the more remarkable, considering that Tamoxifen is classified by the World Health Organization and the American Cancer Society to be a human carcinogen, and is technically a xenobiotic chemical – inherently toxic and biologically alien to human physiology.
