Hello, 

BAMS, of-course has the greater potential than BHMS. Ayurveda is getting an edge over allopathy etc. Also, 

After the course completion (BHMS), you may find employment as

:1. Homeopathic practitioner in both India and abroad.2. Medical representative at a private or government hospital.3. Professor or a researcher in any homeopathic college.4. You may start personal clinic.5.  You may work in industries dealing with homeopathic preparations.6. You may work in public and private sector

Opt for the course that you love the most and are most passionate about and analyse the future work conditions. 

Hope this helped. 

Good luck!
