The use of Calamus in foods is prohibited in the United States by the FDA. Whether or not it can be used as an ingredient in a dietary supplement is not clear. In the 70's and '80s, studies demonstrating carcinogenic activity in animals were conducted with rodents fed or injected massive doses of beta - asarone. The Indian variety of Calamus contains beta-asarone and was subsequently banned from use in foods in the United States. Pending clarification on this issue, Banyan's bulk Calamus powder is not for human consumption.
Calamus powder is commonly used externally during Pancha Karma or after Abhyanga (self-oil massage) to remove oil. It is a highly aromatic herb that supports the proper function of the lymphatic system and enlivens the skin. As an ingredient in massage oils, Calamus stimulates the body and helps to remove natural toxins. It can also be used in nasya (nasal) oils to sharpen the mind and increase awareness.*
