Regarding Insulin plant I had clarified with an Aayurveda doctor. He said "this is not a plant/herb of Indian origin & so there are no details available in our shaastra (science) literature (scriptures) & so we (Aayurveda practitioners) do not prescribe or administer any part or preparation of Insulin plant to patients."
I have the plant with me but could not use or test it because before getting it, my blood sugar was normal with LWMDR. I have not destroyed the plants completely, due to curiosity or fancy . Occasionally pull out few ones to keep the bush not grow to a forest ; it requires no attention than watering.
