Can cupping therapy be used for excessive dampness?

Under normal circumstances, cupping therapy can be used to address excessive dampness. Cupping is an important clinical and health-preserving method in Traditional Chinese Medicine (TCM), particularly effective at expelling pathogenic factors—such as wind, cold, and dampness—that reside on the skin and muscular surface.

As a traditional therapeutic modality, cupping effectively eliminates internal dampness. By stimulating meridians and acupoints, it promotes blood circulation, resolves blood stasis, regulates Qi and blood flow, dispels cold and dampness, harmonizes Qi and blood, and balances Yin and Yang—thereby facilitating the expulsion of cold-damp pathogens from the superficial musculature.

Patients with excessive dampness commonly undergo cupping along the Spleen, Stomach, and Bladder meridians to remove dampness. Acupoints especially effective for dampness removal include Fenglong (ST40), Chengshan (BL57), Zusanli (ST36), Yinlingquan (SP9), and Pishu (BL20).

However, it should be noted that cupping for dampness removal may cause minor trauma to local skin and mucous membranes; therefore, daily cupping is not recommended. Two to three sessions per week are generally appropriate. Additionally, after cupping, local pores remain open; thus, patients must take care to stay warm and avoid re-invasion by external damp pathogens.

Excessive dampness primarily arises from dysfunction of the Spleen. While undergoing cupping therapy, individuals with dampness accumulation should also focus on Spleen nourishment—specifically avoiding raw, cold, or hard-to-digest foods, and instead consuming more foods that strengthen the Spleen and resolve dampness. Regular physical activity is also essential to promote Qi and blood circulation, enhance Yang Qi, and accelerate metabolism.
