The Union health ministry should take action against yoga guru Ramdev as he has misled people by making "unlearned" statements against allopathy and defamed scientific medicine, the Indian Medical Association said on Saturday.

Ramdev should be prosecuted under the Epidemic Diseases Act as "untutored" statements are "a threat to the literate society of the country as well as to the poor people falling prey to him", the apex doctors' body said in a statement.
