I suffer from idiopatic polyneuropathy, and found the Hsin Kuang site, where they offer herbal medicin for curing this.
I have tested it for two months, and it helped a bit, but didn´t cure the disease. I am quite convinced that it´s not herbal things I have been eating, but cortison.
My inflammations has gone down, but my skin is quite weaker and affected - just as a side effect of cortison cures.
I also asked the Hsin Kuang to get the money back - nothing has happened for two months, so I consider my selves as cheated.
