Cupping Techniques
1. Retention Cupping
This is the most commonly used method of cupping, also known as stationary cupping, which involves placing the cup on the skin and leaving it for a period of time. The retention time ranges from 5 to 20 minutes, depending on the patient’s condition, the disease, and the season. Generally, in summer and on thinner skin areas, the retention time should not be too long.
Retention cupping has two forms:

One is single cup cupping, which uses a single cup and is suitable for small areas of pathology.
The other is multiple cup cupping, also known as dispersive cupping. The cups are generally placed along the muscle bundles, nerves, or meridian pathways. If the body is strong, the cups can be placed closer together; if the body is weak, they should be spaced further apart. This method is suitable for broader areas of pathology.
2. Flash Cupping
Flash cupping involves holding a cup in one hand and using tweezers to hold a cotton ball soaked in alcohol or a cotton ball tied to a wire, igniting it, and then quickly removing it to place the cup on the patient’s affected area. The cup is then immediately removed, and this process is repeated several times until the skin becomes red and shows bruising. This method is suitable for areas where the muscles are more relaxed.
3. Sliding Cupping
Sliding cupping, also known as push cupping or pull cupping, involves selecting a cup with a larger opening, thicker walls, and a smooth, undamaged surface. A thin layer of lubricant, such as liquid paraffin, petroleum jelly, or other vegetable oils, is applied to the area to be cupped. After using the flash or fire cupping method to create suction on the skin, the cup is held at the base and tilted slightly to slide it back and forth. The directions can be forward, backward, left, right, and can also include rotation. This is repeated several times until the skin becomes red and shows bruising. It is suitable for large, flat areas of the body with thick, firm muscles, such as the back and lower back.
Effects of Cupping

Cupping therapy has therapeutic effects of invigorating qi and blood, dispelling cold pathogens, and alleviating pain and swelling. It is suitable for conditions such as shoulder periarthritis, cervical spondylosis, rheumatoid arthritis, neuralgia, low back pain, trigeminal neuralgia, and sciatica.

Precautions for Cupping
1. After gua sha and cupping, do not take a cold shower or drink cold beverages for two hours. If taking a shower after two hours, use warm water.
2. During gua sha and cupping, do not use air conditioning or fans to avoid air convection.
3. Do not perform cupping on an overly full or hungry stomach; wait at least one hour after eating.
