Dear student, BHMS will seek you a degree for practising medicine. Whereas, B.Pharma will let you become only a graduate in pharmacy. You will be able to work in the production or QA or QC department in a pharma company. At max, you will be able to open your own medical shop. However, as a doctor, you shall not only be able to get a job but also you shall be free to practice privately. The best part is that you shall be authorized to treat patients which you will never ever be able to do after B.Pharma. 

The scope of Homeopathy medicine is quite wide. It is one of the best systems with minimum drug and maximum results with no side effects. I hope this would suffice.

All the best

Hope this helps
