What cupping method is commonly used for treating erysipelas and sprains?

Generally, cupping therapy is a treatment method that creates negative pressure on the skin surface to promote the circulation of qi and blood and unblock meridians. For treating erysipelas and sprains, common cupping techniques include dry cupping, wet cupping, fire cupping,刺络拔罐 (pricking and cupping), and medicinal cupping. If discomfort occurs, it is recommended to seek medical attention promptly. Specific details are as follows:

1. Dry Cupping

Dry cupping is one of the most common cupping methods. When treating erysipelas or sprains, the practitioner applies ointment or salt to the affected area, then places a glass or plastic cup over it and removes the air inside the cup to create negative pressure. The cup adheres to the skin, stretching and stimulating local tissues, thereby improving blood circulation and lymphatic drainage, helping to relieve symptoms of erysipelas and sprains.

2. Wet Cupping

Wet cupping involves placing the cup on the affected area after heating it with hot water to create internal pressure changes that generate suction. This method is suitable for acute inflammatory conditions such as sprains, and helps relax tendons, unblock meridians, and regulate qi and blood flow.

3. Fire Cupping

Fire cupping uses a flame to heat the inside of the cup before placing it on the skin, creating a negative pressure effect that promotes the circulation of qi and blood and clears blockages in the meridians. It can help alleviate pain and swelling caused by erysipelas and sprains. Fire cupping should be performed by an experienced traditional Chinese medicine (TCM) practitioner to avoid burns and other adverse reactions.

4. Pricking and Cupping Method

The pricking and cupping method involves lightly tapping the affected area with a dermatological needle before applying cupping. Acupoint selection is based on TCM meridian theory and the patient's specific condition. For erysipelas, points with blood stasis such as Xuehai (SP10) and Sanyinjiao (SP6) may be selected. For sprains, corresponding acupoints near the injury site, such as Chengshan (BL57), are commonly used.

5. Medicinal Cupping

Medicinal cupping is a commonly used TCM therapy that combines the effects of herbal medicine with the negative pressure of cupping. It involves placing ignited medicinal herbs into the cup, then quickly applying the cup to specific acupoints or affected areas, producing both thermal and transdermal herbal effects. Herbs are selected according to the individual’s condition and may include those that dispel wind-cold, invigorate blood circulation, resolve blood stasis, reduce swelling, and relieve pain. Commonly used herbs include mugwort leaf (Ai Ye), Chuanxiong (Ligusticum), safflower (Hong Hua), and dang gui (Angelica sinensis).

In addition to cupping therapy, rest is very important. Excessive movement or use of the injured area should be avoided to prevent worsening symptoms or further injury.
