The US National Cancer Institute has found that Maharishi Amrit Kalash (MAK) 4 and 5, ayurvedic formulations developed by the Maharishi International University, significantly inhibit cancer cell growth in both human tumour and rat epithelial cell systems. Prepared from a wide variety of herbs and spices in a base of wholecane sugar, ghee and honey, MAK has also been found to enhance cognitive functioning, prevent illness and alleviate detrimental effects of the aging process.
