I am extremely sensitive to plant hormones or precusors (for instance, using a very strong cup of chamomile tea to help me sleep, will spike my hormones the following day—it contains apigenin, which has benzo-like properties but also functions as a phytoestrogen). This makes certain herbs and essential oils impossible for me. I worry about resveratrol therefore. Will knotweed have a similar effect? Thanks.
Resveratrol has been found to have some estrogenic properties. The only way to know if it will affect you negatively is to try it alone and see. If it does, I would suggest stephania instead.
