Have you ever used Dang Gui(female ginseng) to treat period pain, pms or heavy periods?

Please consider discussing this with a GYN instead of trying home remedies. There are female problems such as endometriosis that can cause real problems, including anemia, if left untreated. Such problems can become very severe, including possibly requiring minor surgery, so have a doctor advise you. Make sure that you have sufficient iron in your diet too. One sign that you may need a supplement is if you are very out of breath after walking upstairs.
