The herbal mixture MAK-4 (Maharishi Arnrit Kalash-4) was tested for anticarcinogenic and anticancer properties against 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary tumors in rats. The 6% MAK-4-supplemented diet protected against DMBA-induced carcinogenesis by reducing both tumor

incidence and multiplicity during initiation and promotion phases. MAK-4 provided up to 88% protection (p<0.05) during the promotion phase, and 60% (p<0.05) during the initiation phase of carcinogenesis. Also, 60% of the control animals which had developed fully-formed tumors showed tumor regression when their diet was subsequently supplemented with MAK-4 for four weeks. In 30% of these rats, the tumor regressed completely.
