Hi Lewood, I'm glad you asked about Vitex, agnus cactus. I heard wonderful things about it too. It supposedly takes a few weeks or even months to build up in your system. After 2 months my cycles lengthened from 25 to 27 days, which I was happy about. BUT.... I got terrible hormonal acne, and I'm pretty sure it was from Vitex. I think it was just too much for my body to handle. I'm now having to treat cystic acne that is all over my neck and chin. Also, I had an ovarian cyst rupture the 2nd month taking it. I think that may be from it too.
Maybe, talk to you doc before taking it. I think it's safe, but if you have side effects it may be working too well, and contradicting what you are intending to use it for.
GL!!!!!
