Sir,The present global public health crisis is nuclear denotation which is a result of tsunami attack to nuclear electricity power plant in Japan. The prevention of leaked ionizing radiation is the focus topic in medicine. At least, the potassium iodide prophylaxis is recommended for the people living in high contaminated area. The drugs/formulation mentioned in Ayurveda like Triphala can help for health prevention in post crisis is interesting. Here, the author briefly discusses on this topic.Triphala is an Ayurveda regimen with many evidences on its preventive usefulness for exposure to ionizing radiation. According to the animal model study, Jagetia et al. detected that “the ability of triphala as a good radioprotective agent and the optimum protective dose of triphala was 1/28 of its LD50 dose.”[1] Jagetia et al. reported that “triphala was found to scavenge (.)OH, O(2) (.) 2,2’-azinobis(3-ethylbenzthiazoline-6-sulfonate) diammonium salt (ABTS)(.+) and NO(.) radicals in a dose dependent manner.”[2] It is concluded that triphala is a possible useful drug in the treatment of cancer due to its antioxidative property.[3]Similar to triphala, chyavanaprasha is also reported for its radioprotective property. It is reported that “chyavanaprasha can provide good radioprotection at a very low non-toxic dose.”[4] This regimen is a potent and possible novel therapeutic agent that poses anti nitric oxide activity. In a study, the scavenging of nitric oxide by chyavanaprasha is more than that by triphala.[5] Hence, it is regimen as an Ayurveda regimen for use during cancer treatment.[6]In conclusion, Ayurveda regimens have radioprotectant potentials and, therefore might be the useful alternative preventive regimens in the present nuclear materials contamination crisis.
