BAMS

According to a survey in 2020 around 80 antibiotics won't work in human bodies. Howa days whatever we are eating has chemicals and that is why we are getting ill so early.
Looking to such scenario people around the world not even India are opting Ayurveda. So as ayurveda is increasing since few years and jobs related to ayurveda is. So as for as i think either BAMS or B pharmacy in ayurveda is good to opt. After 5 years definitely it will offer good career.

To open n run medical stores you must have either d pharma or b pharma ( allopathy or ayurved). You will have to be registered also to run medical store. BAMS is a Pantone in ayurvedic system. So its quite not possible.

I think B. Pharmacy is the better option.

Under graduate in ayurvedic or homeopathy is a good idea and since you are from bio background it totally depends on your interest. Both ayurveda and homeopathy are two different domains in medical studies. Both are having equal importance in present time. Most of the people using homeopathy and ayurvedic medicines for curing their diseases. So better think and choose one out of two in which you are really interested.
All the best!
