The herbal mixture Maharishi Amrit Kalash-5 (MAK-5) was tested for antineoplastic properties against 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary tumors in rats. The 0.2% (w/w) MAK-5-supplemented diet protected against DMBA-induced carcinogenesis during the promotion phase by reducing both tumor incidence and multiplicity. MAK-5 provided up to 62.5% protection (p<0.05) during the promotion phase of carcinogenesis. Also, a MAK-5-supplemented diet fed for four weeks to control rats which had developed mammary tumors, decreased tumor size in 60% of these rats.

There was no significant difference in weight gain in rats on the MAK-5-supplemented diet. Thus, the MAK-5-supplemented diet did not influence the food intake, but protected against DMBA-induced mammary tumors in rats.

Please Note

MAK-5 is now called Amrit Kalash Ambrosia.
