Researchers at National Institute of Technology (NIT), Warangal are developing a cure for cancer from the abundantly available Tulsi leaves. The plant is a bush that grows extensively in the tropics and is even worshipped at homes locally. Medicinal value of Tulsi leaves is known to Indians since ages. At NIT, they have extracted the substance from Tulsi leaves, which they have discovered, is a sure cure for cancer. Thus a cheap drug for cancer can be manufactured, the researchers said.
