Maharishi Ayurveda, a recent restoration of the traditional health care system of India, upholds an herbal fruit concentrate (M-4) and an herbal tablet (M-5) as rasayanas—food supplements that promote physiological balance, health, and immunity. The superoxide scavenging properties of M-4, M-5, and ascorbic acid were investigated with superoxide radicals generated during the catalytic activity of xanthine oxidase. M-4 and M-5 (10 mg/ml prior to centrifugation) inhibited the reduction of nitroblue tetrazolium (NBT) 98% and 96%, respectively. 50% inhibition of NBT reduction was obtained with 0.04 mg/ml M-4 and 0.15 mg/ml M-5. Ascorbic acid inhibition of superoxide radical reduction of NBT reached 88% at 1 mM, but declined to 42% at a concentration of 10 mM. The rate of uric acid production monitored at 290 nm demonstrated negligible inhibition of xanthine oxidase by M-4, M-5, or ascorbic acid. The results contribute to an understanding of previously reported antineoplastic, antioxidant, and anti-aging properties of M-4 and M-5, and warrant consideration in the light of present preventive, nutritional, and chemotherapeutic approaches to health, antioxidant defense, and carcinogenesis.

MAK-4 is now called Amrit Kalash Nectar.
MAK-5 is now called Amrit Kalash Ambrosia.
