I am planning to work on the integration of ayurvedic drug and allopathic system using an animal model. So kindly suggest good ayurvedic or herbal medicine for the treatment of diabetes but which are not scientifically validated.
There are number of herbal medicines useful for diabetics available in India which has been not recognized yet for general treatment purpose. There are several Herbal medicine companies claiming that they have a unique combination of herbs for the management of Diabetes mellitus but I dont think they are available easily and well recognized.
First you need to identify herbs or minerals that are used in the treatment of diabetes by searching in research papers.This will give a base to start from.Thereon you will be able to develop data that will lead to an answer to your question.
