Are you curled up in bed for a day or more each month with one thought:  "What am I going to do about these period cramps?"  You are not alone, as 50% of menstruating women have the same experience month after month.   But why suffer when you could be living pain free?  NSAIDs (Non-steroidal anti-inflammatory drugs*) only mask the pain for a few short hours.  Chinese herbal medicine, on the other hand, has been used for centuries with well-documented results. 

An international nonprofit organization, known as the Cochrane Collaboration, studied the effectiveness of Chinese herbal medicine in relieving menstrual pain compared to western drugs.  Their conclusion:  "Chinese herbal medicine for primary dysmenorrhea roughly doubled pain relief and improvement in overall symptoms compared with conventional Western pharmaceuticals," reported Xiaoshu Zhu.

Here are a few common Chinese herbs used for painful menstrual cramps:
1. Radix Angelicae Sinensis (Danggui)
Also known as the "female ginseng," it is commonly used to regulate the menstrual cycle and relieve menstrual cramps.  It also helps to relieve menopausal symptoms, reduce PMS and anemia and to re-establish a menstrual cycle after cessation of birth control pills.  It is commonly sold as a single herb tea, bagged or loose.  It is considered a king herb or premier herb in Chinese gynecological disease because of its ability to harmonize the blood in Chinese medicine.  Dong Gui is also considered antispasmodic.  The coumarin chemicals present in this herb may help dilate blood vessels and relax the smooth muscles of the uterus, thus relieving menstrual cramping.

2. Chuanxiong (Rhizoma Chuanxiong)
This herb is also a key medicinal herb for treating pain.  It improves blood circulation and promotes the flow of "qi" or vital energy.  Chinese women, dating back to the Song Dynasty, used to take this Chinese herb in the form of soup.  The soup is called a Four Substance Decoction and includes three other herbs:  angelica, red peony and Chinese foxglove.  The soup and tea are still used today as a blood tonic to relieve PMS, stop menstrual pain and improve overall health, especially after giving birth.

3. Radix Paeoniae Alba (Baishaoyao)
White Peony Root nourishes the blood and improves circulation.  It is also used for a wide variety of gynecological problems.  The peony root is considered a   liver tonic in Chinese medicine.  By strengthening the liver, it helps to increase the efficiency of protein and fat metabolism, thus inhibiting the excessive synthesis of prostaglandins that may cause an over-active uterus and endometrial pain.

4. Herba Leonuri (Yimucao)
Leaves from this herb are used to treat menstrual problems.  They have been shown to improve blood circulation and clear blood clots that occur in menstrual disorders and after childbirth.  The leaves also promote diuresis and relieve edema.  Studies on the alkaloid leonurine showed that this substance stimulates the uterus of rabbits, cats, dogs and guinea pigs.

5. Rhizoma Corydalis (Yanhusuo)
There are two main functions of this Chinese herb:  to strengthen blood circulation and to relieve pain.  In conjunction with chuan xiong it is known to help both body aches and headaches.  Corydalis is related to the opium poppy.  Although only 1% in strength compared to opium, it is a very effective pain reliever.  The active chemical constituent di- tetrahydropalmatine (THP) is a neuroactive alkaloid with analgesic action that relieves cramping pain.

Groups of Chinese herbs, also known as formulas, are more beneficial than single herb remedies because the herbs work synergistically for conditions such as menstrual cramps.  The Cochran study also stated that:  "The herbal remedies were also significantly better at relieving painful cramps and other symptoms than acupuncture or a hot water bottle, with overall promising findings  Chinese herbs overall, whether standardized or tailored, yielded better pain relief than conventional pharmaceutical therapies."
