The Supreme Court on Tuesday came down heavily on yoga guru Ramdev’s Patanjali Ayurved for prima facie violation of the undertaking given by it in the court about its products and also about statements claiming their medicinal efficacy.

A bench of justices Hima Kohli and A Amanullah issued a notice to Patanjali Ayurved and its managing director asking why contempt proceedings should not be initiated against them. The bench also cautioned Patanjali Ayurved and its officers from making any statements adverse to any system of medicine in the media, both print and electronic, in any form as they said in their undertaking before the court earlier.
