I am still concerned when using a drug of any kind. Never have a found the body deficient in a drug. It may try to normalize the immune system and cause the symptoms of the disease to dissipate but curing a disease is not accomplished.
An autoimmune disease is brought on by an imbalance in cells, something goes wrong; a drug does not alter the cause. Such diseases if the cells are studied within the disease area, such as MS along the nerves or cancer or lupus, etc; all have locations where the cells diseased will have a bacterium living inside causing the cells to do what they do. Kill the bacterium and the disease reverses. As incredible as it sounds if you look at the Science of it, you will find it is as logical as giving an Antibiotic for a bacterial infection. Take a look at jesichashope.org and read up on the BX Antitoxin, many like you with MS are now living life without it; as does others with autoimmune diseases. Why live it when you can live without it?
