The drug regulatory agency in Canada , Health Canada has warned the consumers not to use certain ayurvedic medicinal products from India, based on the recent controversial JAMA study report accusing Indian Ayurvedic drugs of containing high levels of toxic metal content. Health Canada has also stated that it would soon take action to remove these products from the market and to prevent further imports into Canada.
Canadians have also been advised by the drug regulatory agency not to use any Kerela, Safi, Maha Sudarshan Churna, Yograj Guggul, Sudarshan or Shilajit products as they lack market authorization .Some of drugs that have been banned include the Karela tablets (Shriji Herbal Products); Karela capsules (Himalaya Drug Co); Maha Sudarshan Churna powder (Zandu Pharmaceuticals), Maha Sudarshan Churna powder (D& K Pharmacy, Bhavnagar), Maha Sudarshan Churna powder (Chhatrisha, Lalpur), Maha Sudarshan Churna powder (Dabur India Ltd); SAFI liquid (Hamdard-WAKF); Yograj Guggul tablets (Zandu Pharmaceuticals); Sudarshan tablets (Zandu Pharmaceuticals) and Shilajit capsules (Dabur India Ltd).
Findings of a study recently published by Journal of the American Medical Association (JAMA) has indicated that one of the 5 Ayurvedic herbal medicine products (HMP) produced in South Asia contains potentially harmful levels of lead, mercury or arsenic above permissible levels, and it said users of Ayurvedic medicine may be at risk for heavy metal toxicity, and testing of Ayurvedic HMPs for toxic heavy metals should be mandatory.
However a spokesperson from Darbur India when asked to comment on the article published by JAMA has been stated as saying that" Metals form an integral part of many Ayurvedic medicines as they (metals) have therapeutic properties and that Ayurveda has well established detoxification procedures to remove toxicity from these metals and make them safe for human use and Companies like Dabur use Good Manufacturing Practices and follows API standards, issued by Government of India, for procurement of raw materials, detoxifying them and for processing them into different formulations hence making all the medicines manufactured by them safe for human consumption."
