Holistic Chronic Pain Management: Natural Therapies and Supplements

I have been taking epsom salts all year every morning a few spinkles in my 500m water bottle (room temp water) and my aches and pains have all but disappeared. I remember my grandmother always put epsom salts in her tea each morning just a few sprinkles and she said so she did not get arthritus. Well I have to say I think it works but what I want to know is too much bad for you internally anyone know thanks
