BDS

I think you should opt for BAMS because day by day, the scope of Ayurveda is overlapping the other medical systems, not only in India but also in the world.
In many cases, people have taken the experience for the trustfulness of the Ayurvedic system and medicinal treating for chronic and non-healable diseases.
In many cases, when the allopathic system becomes a failure with a particular disease and surrenders, the Ayurvedic medicine does the magical effect to rejuvenate the illness or the patient.
Job opportunities also exist in the government sector. One can get a job in a government Ayurveda hospital as an Ayurvedic pharmacist.
After the completion of this course, candidates also have the opportunity to open their own retail shop of Ayurveda medicines. Teaching field is also open for BAMS graduates. They can find employment in private and government Ayurveda institutes.
All the best.
