Yingxiang point is located in the face, next to the center of the outer edge of the nose, nasolabial groove. It can clear the nose and orifices, clear the lungs and remove heat, and disperse wind. It is mainly used for treating nasal congestion, congested epistaxis (nosebleed), crooked mouth, itchy face, and biliary ascariasis.

The Yin Tang point has the effects of clearing the nose, brightening the eyes, clearing the brain and calming the mind. It is useful for acute and chronic rhinitis, colds, and nasal congestion leading to loss of sense of smell.
