Legally and technically the degree of BHMS is accepted as one of courses to be practiced just as Allopathy, Ayurved, Unani etc. There’re other degrees as well like BNYS which are allowed to practise but they can’t be called a “Doctor”. Similarly, an Ayurvedic medical professional will better be called a Vaidya and a Unani professional be called a Hakim rather than “Doctor”. But once again, legally all of them are doctors and can be called doctors.
