Clinical trials on Ayurvedic drugs
Preliminary research has been conducted into the use of ayurvedic remedies for treating rheumatoid arthritis, but no firm evidence was produced.
The U.S. National Institutes of Health states that "Most clinical trials of Ayurvedic approaches have been small, had problems with research designs, or lacked appropriate control groups, potentially affecting research results."
The Indian Council of Medical Research has issued guidance on conducting trials of ayurvedic substances. It says the substances must adhere to the recipes traditionally used and care must be taken to ensure there is no contamination of plant ingredients.
The government of India has issued draft guidelines.
According to Cancer Research UK, "there is no scientific evidence to prove that Ayurvedic medicine can treat or cure cancer or any other disease".
