What Is Gua Sha?
Gua sha is a traditional Chinese medical practice dating back to the early Imperial period that is making waves in modern holistic health circles. Known by different names throughout south-east Asia, the practice involves the stroking of the skin (a technique known as gua) with a smooth blunted instrument to produce light petechiae (sha).
This stroking process releases toxins from the blood and promotes metabolic cell repair by stimulating blood flow to the affected areas, offering both a medical and cosmetic treatment. Gua sha is used to treat a range of muscular injuries and chronic pain symptoms, often used in conjunction with massage, acupuncture, and heat therapy. This practice targets inflamed areas on the back, buttocks, neck, arms, legs, and even face. Gua sha is certainly versatile and new scientific research continues to highlight its effectiveness in treating a broad range of health conditions.
The earliest reference to this practice can be found in the foundational Chinese medical treatise Shanghan Lun, compiled by prominent physician Zhang Zhongjing after an epidemic swept through his hometown of Changsha (in present day Hunan province). Shanghan Lun, translating as the Treatise on Cold Damage Diseases, is one of the oldest complete clinical textbooks in the world and revolutionised Chinese medicine when it was first published in the early 3rd century.
Shanghan Lun established the “six-syndrome identification system”: Tai-Yang, Yang-Ming, Shao-Yang, Tai-Yin, Shao-Yin, and Jue-Yin, along with the associated symptoms and treatments for each type. The ingenuity of Shanghan Lun was that it addressed illness as an evolving condition unique to each patient and not as a fixed disease. For this reason, the methods outlined in this ancient medical text continue to be used in modern forms of traditional Chinese medicine.
The Chinese medical paradigm of treating cold diseases has interesting parallels with European holistic traditions as both focus on stimulating blood flow and increasing the production of white blood cells.
Although they advocate different processes–direct pressure on the skin and heat therapy—each practice produces similar results. This indicates that a unique synergy exists between these diverse cultural practices.
Harnessing the benefits of gua sha and combining it with Western medical traditions therefore offers an exciting new frontier for holistic practitioners.
How Does Gua Sha Work?
A gua sha treatment begins with the practitioner massaging oil or lotion into the targeted areas, establishing a smooth base for the instrument to glide over. Then, they will use the gua sha instrument to stroke the skin in a series of downward motions with varying pressure.
Working down the muscles and along acupuncture medians, each stroke leaves light red or purple marks as blood is released from capillaries. The distribution of these marks reveals any disruption in flow to the circulatory system, indicating where any problem areas may lie.
The end result is a series of minor bruising across the affected areas, prompting your body to begin cellular repair. Any skin bruising and minor bleeding usually disappears within a couple of days.
When treating facial areas, a much smaller and lighter gua sha instrument is used that does not leave any visible marks. This type of treatment is aimed at exfoliating, treating pigmentation, congestion, and other blemishes.
After massaging moisturiser or lotion into the skin, the gua sha instrument is used to gently stroke the exposed areas. It is advisable to start at the neck and then work up to the face, releasing tension across the entire area. This ensures that any latent toxins are flushed out from the extremities and don’t pool in the body.
