During your period, the wall of your womb starts to contract more vigorously, to encourage the lining of your womb to shed away as part of your monthly menstrual cycle. When the muscular wall of your womb contracts, it compresses the blood vessels that line your womb. This temporarily cuts off the blood supply (and hence oxygen supply) to your womb. Without oxygen, the tissues in your womb release chemicals that trigger pain in your body. While your body is releasing these pain-triggering chemicals, it's also producing another set of chemicals known as prostaglandins. Prostaglandins encourage the womb muscles to contract further, therefore increasing the level of pain.If you have the Symptoms of Adenomyosis--Painful period, we would say herbal medicine is a safe and effective form of treatment.
