When I was taking Zhang's herbs, a couple of times I forgot to order on time and I used Cowdens cumanda and samento while waiting for my orders from Zhang to arrive. I took more than the recommended amount and they did not work for me. Both times I got sick again and then when I got zhang's I continued to decline using both of them. It was not a herx as I never got better and after three months finally realized it and started abx again. I think whatever strain I have became resistant to the herbs. I used herbs after doing abx several months and getting to the point of feeling nearly well but having bad side effects from the drugs. The herbs worked for about 5 months each time and then I went backwards. Maybe the key is to rotate them frequently and start off using them with abx. I think I was sticking to just one thing, one abx (doxy, ketek or levaquin) and one basic herbal protocol. I am just too foggy brained to figure out a good treatment plan and too poor to pay a doctor right now. The herbs need to be taken in much higher amounts than what is recommended and it is very expensive. I was paying between 5 and 6 hundred dollars a month for them.
