Seven-star needle is a traditional acupuncture needle, also known as plum blossom needle. The seven-star needle is shaped like a small hammer with seven short needles embedded in it, hence the name. Seven-star acupuncture has the following clinical effects.

1. Dredge the channels and collaterals, and puncture along the channels and collaterals with a seven-star needle can dredge the qi of the channels and collaterals and have the effect of relieving pain.

2. Exotic evil. Seven-star needle gently pricks skin bleeding, which can dispel the evil of abdominal cold and damp heat.

3. How to regulate Yin and Yang? Choosing appropriate acupoints and beating with a seven-star needle can promote Yang Qi, but it is not effective for muscle weakness.
