What are the exact locations of Yingxiang and Bitong acupoints?

Yingxiang (LI20) is located beside the midpoint of the lateral border of the ala nasi, in the nasolabial groove; Bitong (EX-HN13) lies at the junction of the alar cartilage and the nasal concha, near the upper end of the nasolabial groove. Both are commonly used acupoints for nasal conditions, and massage on these points may help relieve symptoms related to rhinitis. If redness, swelling, pain, or no improvement occurs after massage, medical advice should be sought promptly.

The location of Yingxiang can be accurately identified using surface anatomical landmarks. The midpoint of the lateral edge of the ala nasi serves as the key reference point, while the nasolabial groove is the natural depression between the ala nasi and the cheek. This acupoint lies precisely where these two landmarks meet. A mild sensation of soreness or distension is typically felt upon pressing, with one point on each side of the face. It is a key acupoint for relieving nasal discomfort.

Bitong is positioned slightly higher, in the area above the ala nasi where it meets the nasal concha, close to the upper starting end of the nasolabial groove—approximately 1 cm away from Yingxiang. It lies within a facial depression beside the nose, producing a relatively noticeable soreness or distension when pressed. Located symmetrically on both sides, this point is frequently used to alleviate nasal congestion, runny nose, and similar symptoms.

Before performing massage, hands should be cleaned thoroughly. Use the pulp of the index finger to gently press the acupoints for 1–2 minutes per session. Apply pressure until a sensation of mild soreness or fullness is felt, taking care not to press too hard and risk skin damage. Regular nasal hygiene can be combined with this practice, keeping the skin around the acupoints clean and dry. After massage, avoid direct exposure of the nose to cold air to enhance the therapeutic effect of acupoint stimulation.
