In the past I took this with a combination of other herbs to stabilise heavy periods. I have to say it worked very well for me and did not affect me adversely in anyway. I am type 1 diabetic. I would advise you to see a qualified herbalist for example someone who has a qualification in Phytotherapy and has studied the things formally.(In London there is a Clinic of Phytotherapy) It is just herbs do make a difference and depending on what your problems are you need to get advice on the dosage and the form in which you take it. If you can access Baldwins on Walworth Road. London SE17 they sell herbs and give advice.
