I used MilkThistle powder, Astragalus powder, Yellow Dock Root Powder and Gingseng powder together regularly at every meal (breakfast & dinner, I always skip lunch) and started to experience positive effects in 2 days; first my left-knee pain got less then my face started to turn from red to white (my original skin color). I ordered these again and started using them and I do not think I will stop using them even after completely healed.
I am not an expert at all but believe that SpiritOfHealth does a good job in picking up the best quality herbs in the market.
