Menstrual cramps affect more than 50 percent of women worldwide and more than 15 percent suffer from severe cramping that limits physical activity. The process of acupressure, which involves applying pressure to spots on the body known as acupoints that correspond to junctions of physiological systems, can reduce the pain associated with menstrual cramps.

Women suffering from menstrual cramps can use a variety of acupressure points to relieve pain and other symptoms. The basic technique is to locate the acupressure point and apply pressure using the tip of the finger, the knuckle or a soft rounded object, such as a pencil eraser. Pressure should be applied for 1 to 3 minutes, but care should be taken to ensure that the fingers remain comfortable while applying pressure.

Acupoints are named for the part of the body they correspond to rather than the part of the body where the acupoint is located. For instance, an acupoint commonly used for menstrual cramping is "Three Yin Intersection" (the Chinese term for which is San Yin Jiao), which is located behind the calf, about three inches from the ankle. The acupoint is also known as SP-6 or "Spleen 6" because it is part of a pathway that Chinese medicine specialists believe includes the spleen.

Other acupoints known to help with menstrual cramping include:
The Sea of Energy (Qi Hai) located two finger widths below the belly button. Also called Conception Vessel (CV) 6. The CV-6 point is also used to treat digestion problems, edema, and bloating.

The Inner Pass (Nei Guan) located approximately 2 inches from the wrist on the inner arm. Also known as Pericardium (PC) 6. This point has also been demonstrated, in clinical studies, to relieve vomiting and abdominal problems during pregnancy.

The Union Valley, Hegu (LI 4), located in the webbing between the thumb and the forefinger. Also known as Large Intestine (LI) 4. This point is believed to aid in any problem involving chronic pain.

The Wind Pool, Acupuncture Single Point Fengchi, located at the rear of the skull about two to three inches from the ear. Also called Gall Bladder (GB) 20. The GB-20 point is often prescribed for headache and hypertension.

The Leg Three, Zusanli (ST 36), located about one finger width from the juncture of the tibia on the outside of the leg. Also known as Stomach (ST) 36. The ST-36 point is also used to relieve any other issue involving the stomach or spleen.

The Middle Gate, (Mu Guan) located about one finger width from the wrist crease on the palm. This is an extra point discovered by Master Tong, although it is on the Pericardium (PC) pathway. Mu Guan is also used for heel pain.
