Nope! A BEMS doctor can't prescribe homeopathic medicine. As per the guidance of MCI, only an registered practitioner under MCI having a minimum of MBBS/BDS degree can only prescribe Allopathic medicine.

BEMS is an advanced technique for treatment in which focus on the homeostasis between the lymph and blood of perished people. You can recommend homeopathic medicines.

I hope this answer helps. All the very best for your future endeavors!
