If you only wish to sell Ayurvedic products, then you will only require a retailer license. Both the online and offline sale of such drugs requires only this trade license. However, to acquire such a permit, the business needs first to register itself under the Companies Act. Moreover, only after incorporating itself as a legal business entity in India, can the owner apply for an AYUSH retail license. Afterward, they will need to open a company bank account and complete tax registrations. In case you want to start a manufacturing unit, you will need an Ayurvedic medicine manufacturing license from the State Drug Controlling Authority.
