I am pursuing B.Sc (Honors) botany. Is M.Sc herbal sciences a right choice for career?

Dear, There is a very less scope as a career prospect as herbal industry has limited bounds. But you can apply to a good agricultural university as a lecturer or government department as a scientist or research associate.

M.Sc (Herbal Science) degree holders have plenty of opportunities in some of its specialised fields such as in Herbal Medicine, Anthropology, Acupuncture, Naturopathy, Health Sciences, Botanical Medicine, etc. These degrees serve as a basis for higher studies in this field such as Ph.D and M.Phil He

Yes, you can do M.Sc in herbal science. It is a good choice for your career as it has a lot of scope. So, you can do M.Sc in herbal science after completing graduation. Good luck.
