By taking 500 mg of Ashwaghandha twice a day, i.e after breakfast and after dinner, all my symptoms of Hyperthyroidism/ graves disease came down in two weeks and I am permanently cured. If this remedy works for you, continue the treatment for one and a half years since it takes a long time for the adrenal glands to heal (see article by Dr. Axe for the connection between adrenals and thyroid glands).
I also took and continue to take Patanjali's Madhunashini Vati and Mukta Vati to stabilise blood sugar and blood pressure, both of which were not normal due to hyperthyroidism. Now I take no allopathic medicine at all.
Ashwaghandha is also curing my melasma which was on my entire back, hands and face. This is happening gradually and permanently.
