What should you consider when using gua sha?

Gua sha, a traditional Chinese medicine practice, involves scraping the skin with a smooth-edged tool to enhance circulation and provide various health benefits. It is typically performed on areas such as the back, buttocks, arms, and legs, with a more delicate approach on the face and neck. Practitioners often use oil or serum to ensure the tool glides smoothly across the skin.

This technique is believed to clear stagnant energy (or chi) in the body, which is thought to contribute to inflammation. By scraping the skin in specific patterns, gua sha is said to enhance blood flow and relieve pain.

A 2007 study found that gua sha could boost circulation in micro-vessels for up to 25 minutes post-treatment. Participants also reported immediate relief from muscle pain, and these benefits persisted in follow-up visits.

According to Medical News Today, applying pressure to specific points on the face and neck during gua sha can help reduce puffiness by promoting lymphatic drainage and muscle relaxation.

A 2022 article in the Journal of Cosmetic Dermatology suggested that short-term use of gua sha can reduce puffiness through improved lymphatic drainage. Regular sessions may also lead to better vascular dilation responses.

While gua sha is generally safe, there are some potential side effects to consider:

Bruising
The technique may cause small capillaries near the skin's surface to burst, resulting in red or purple bruises (known as sha). These bruises are typically tender but heal within a week. They can be managed with over-the-counter pain relievers like ibuprofen, and gentle heat may help reduce inflammation.

Skin Damage
There is a slight risk that the practice could cause the skin to break, increasing the possibility of infection. Practitioners must ensure their tools are properly sterilized between sessions.

Bacterial Infection
Although rare, bacterial infections can occur if the skin is torn or bleeds. To minimize this risk, it’s essential to sterilize tools properly or select a provider who follows strict hygiene practices.

Additionally, gua sha should not be performed on open wounds or irritated skin. Individuals who take blood thinners or have clotting disorders should consult healthcare professionals before starting gua sha treatments.
