In an effort to validate Ayurvedic medicine, a team of city scientists and medical practitioners have started work towards gathering evidence on how 40 traditional herbal drugs prescribed by the 6th century physician Vaghbhata, function at a cellular level in animal tissues and organs through the use of radionuclides. Radionuclides, also referred to as radioisotopes, are chemical substances that exhibit radioactivity. Presently, Ayurvedic doctors prescribe drugs without knowing how they function at a molecular level in the human body. Even the extent of its localisation around the organs, to gauge effectiveness of prescribed dosage, is not known,” said Dr RD Lele, head of nuclear medicine at Lilavati Hospital and the brain behind the project. “We want to study the mechanism of action of the drug in the body
