SAN FRANCISCO, Aug. 4 (Xinhua) -- More than 250 U.S. and Chinese practitioners of traditional Chinese medicine (TCM) met in Seattle Saturday to share their knowledge and experience as the fourth American TCM Congress kicked off.

The two-day annual event is focusing on gynecology, germatology and cosmetology, according to the event's general affairs chief Ma Lei.

Ma said a lecture given by a Chinese professor on women's healthcare and polycystic ovary syndrome (PCOS), a hormonal disorder, interested many people.

"A lot of American women here are suffering from PCOS and TCM prtactitioners here wanted to more know about the insights of Chinese TCM grandmasters on the treatment of the disease by using TCM," she said.

Dan Bensky, a veteran TCM practitioner in the United States and co-founder of the Seattle Institute of Oriental Medicine, was a special guest.

The event, hosted by the American TCM Association and the TCM American Alumni Association, is supported by several Chinese healthcare product manufacturers.
