Think twice on herb Japanese Knotweed
Nice trusted brand, but for herb it was a bit pricey when I bought it. Also the active ingredient is the half of 500 mg. The remaining herb stuff, includes molecules that can cause diarrhea (known possible side effect, nothing to do with the brand), at some people as it happened to me. So I opened it, and took the capsule in thirds and halves, and that prevent diarrhea for me. It tastes like soil, but I can manage a lot of weird tastes. Now I have moved to condensed forms from grapes (like 99% active trans form), with no side effects.
