The use of honey as a therapeutic agent dates back at 8000 years and has markedly increased interest into its potential
health benefits. The by-products of the flower nectar have a complex chemical composition which promotes benefits in
underlying mechanism of human diseases. Malaysian Tualang Honey (MTH) is a multifloral jungle honey produced by
the rock bee (Apis dorsata). This review consolidates the results of carious studies involving biochemical assays of tissue
culture and animal trials of anti-cancer properties of MTH. Often studied in the context of breast cancer cell lines, MTH
has promising data for possible mechanisms in anti-cancer activity. These include apoptosis via depolarization of the
mitochondrial membrane, caspase-dependent apoptosis, reduction of angiogenesis and the promotion of cell cycle arrest
without posing cytotoxic effect on normal cell lines. Despite positive outcomes in tissue cultures, the oral administration
of MTH in breast cancer animal models showed slower tumour progression, reduction in tumour size and better grading
of histological features. The alleviation of breast carcinogenesis via modulation of hematologic, estrogenic and apoptotic
activities promotes MTH as a promising anticancer agent. With confidence in a conclusion that MTH is a useful treatment
for cancer, further experimental and clinical studies should be conducted.
