Surveys estimate that between 30 percent and 90 percent of all women have suffered from premenstrual syndrome, or PMS, at some point in their lives. PMS is characterized by a variety of physical and emotional symptoms that appear during the week before menstruation and continue for about a week afterwards. Among the negative effects associated with PMS are pain, water retention, weight gain, changes in sleep patterns, and general irritability. From a traditional Chinese medicine perspective, the symptoms of premenstrual syndrome may be attributed to an impeded flow of qi caused by stagnation or blockages in the body, leading to irregular menstrual flow and disharmony between qi and blood.
In the United States, severe cases of PMS are often treated with different types of drugs, ranging from synthetic hormones to diuretics to anti-anxiety medications. However, recent studies have shown that a variety of drugless therapies, including relaxation techniques, reflexology, massage and cognitive exercises, may also be effective in alleviating premenstrual symptoms.
Another drugless intervention that may provide relief from PMS is external qigong. In external qigong, a trained practitioner directs his or her own qi outward, with the intention of helping patients clear blockages, remove negative qi and balance the flow of qi in the body, thus relieving pain and helping the body to rid itself of certain diseases. In a recent study published in the Journal of Alternative and Complementary Medicine, scientists in South Korea tested the theory that external qigong could reduce or alleviate the effects of PMS in young women. Their research suggests that qigong can improve many of the symptoms associated with PMS, and that it may work as well as other, more traditional methods of relief.
In the study, 36 women were randomized into two groups. Women in each group received 10 minutes of daily qi therapy (or sham therapy) at 14 days, 7 days, 4 days and 1 day before the menses of two successive menstrual cycles, for a total of eight qi sessions over two cycles. In addition, the women were asked to complete a PMS diary, which documented the severity of 27 common symptoms throughout the study.
External qi therapy was delivered by a female nurse who had practice qi training for eight years and was considered a qigong master. Subjects in the qi therapy group received treatment in the following sequence:
Placebo qi therapy was also performed by a qi master, who mimicked the same techniques and gestures used in real qigong therapy, but without making any effort to emit real qi. To maintain consistency and minimize bias, the same qi master performed the intervention on both groups of patients.
Results
The researchers reported "significant differences" in total PMS symptoms between patients in the qi therapy and control groups. On average, total PMS diary scores for women receiving qi therapy were more than 15 points lower at the end of the study compared to baseline. For women in the placebo group, the average reduction of total PMS scores was less than four points.
On a symptom-by-symptom basis, the scientists also noted "significant improvements" in terms of water retention, pain and negative feelings in the qi therapy group following treatment. They theorized that an improved supply of qi may have harmonized the qi and blood, restoring the health of meridians related to the uterus and accounting for the positive effects.

Some limitations were noted in the study. For instance, the positive results seen among women in the qi therapy group were lower than those seen in women given other drugless forms of care in previous studies, such as massage, cognitive therapy and reflexology. However, the researchers pointed out that the other studies used different measurements when evaluating PMS symptoms. To see how qigong measures up against other treatments, they suggested that "a clinically controlled comparison of several different noninvasive therapies for women using the same PMS assessment form would be valuable."
While external qigong appeared to provide a definite benefit for women suffering from PMS, the authors cautioned that more research needs to be conducted, saying that "... additional evaluation of residual effects of qi therapy is needed for clinical applications. They added that further studies "should also examine the possible effects of qi therapy on the hormonal changes associated with the menstrual cycle to clarify the possible mechanisms involved."

Chronic pain afflicts over 20% of the adult population. Sadly, most MDs have essentially no education in treating pain, beyond offering a few toxic medications. Then they tend to steer people with pain away from those health practitioners who are trained. This puts the acupuncture community on the front lines for addressing this epidemic.
When the body is going through a stressful event, the sympathetic system is activated. This activation will help the body with a life-threatening situation. If this state is activated for prolonged periods of time, it starts to consume energy. These traumatic events that generate stressors in the autonomic nervous system (ANS) will eventually become internalized.

One of the things that makes acupuncture so difficult to measure is that the medicine actually does contain some esoteric aspects. There have been numerous studies that demonstrate the neurochemical reasoning behind why acupuncture points stimulate the autonomic nervous system to enact change However, not all the benefits of TCM can easily be measured by randomized, controlled trials. But does that make them fundamentally and definitively untrue?
