My Brother

My brother has been useing, Herbal Bowel Cleanser and de wormer for about three months and also began fasting and a monodiet. He lost about 50lbs, which he did not need to. He began to behave differently parinod, aggressive withdrawn, sucidal. Now what all of this started with this diet and suppliments. We had to put him in the hospital. He can not think correctly and refuses to stop the diet, now where do we get help to reach him?
