采用艾灸热刺激合谷穴治疗贝尔麻痹患者和健康人，并用红外热成像系统观察面部温度的变化。贝尔氏麻痹患者患侧出现低温或高温，对称性差。健康人表现为前额、眼内侧角、鼻翼及嘴唇周围温度较高，而双侧脸颊温度较低，从而在面部形成“T型热区”，温度对称性好。艾灸治疗11分钟显著改善了贝尔麻痹患者面部温度的高度不对称性。这一证据表明，艾灸合谷可以提高健康人和贝尔麻痹患者的面部温度，特别是嘴唇周围。艾灸合谷穴不仅能改善贝尔麻痹患者的全身循环，而且对唇部有特异性影响，但其作用机制有待进一步研究。
Subjects with Bell's palsy and healthy individuals were treated with moxibustion thermal stimulation on the Hegu (LI4) acupoint; an infrared thermal imaging system was used to observe facial-temperature changes. Bell's palsy patients developed low or high temperatures at the affected side, with poor symmetry. Healthy people showed high temperatures on the forehead, medial angle of the eye, nasal ala and around the lips, but low temperatures on bilateral cheeks, thus forming a “T-type hot area” in the face, with good temperature symmetry. Moxibustion treatment for 11 minutes significantly improved high asymmetry in temperature in the faces of Bell's palsy patients. This evidence indicates that moxibustion treatment on Hegu enables increases in facial temperatures in healthy people and Bell's palsy patients, especially around the lips. Moxibustion stimulation at the Hegu not only improves the global circulation but also has specific effects on the lips in Bell's palsy patients, but the underlying mechanism needs further investigation.
