Efficacy & Actions
This is an extraordinary point located at the prominence of the medial malleolus on the medial side of the foot. It relaxes the sinews and unblocks the collaterals, dispels wind and relieves pain, and unblocks the meridians and benefits the joints. It is an experienced effective point for treating toothache and ankle-foot disorders. First documented in the Beiji Qianjin Yaofang (Emergency Thousand-Gold Formulas). "Nei" refers to the medial side; "Huai" refers to the ankle; "Jian" means tip or prominence. Located at the highest prominence of the medial malleolus – hence the name Neihuaijian (Medial Malleolus Tip). Neihuaijian is an experienced effective point for treating toothache and ankle-foot pain, especially effective for lower toothache and medial calf spasms. It is often combined with Jiache (ST-6), Hegu (LI-4), and Chengshan (BL-57). This point is close to the Kidney Meridian, which courses along the throat and connects to the root of the tongue – thus treating lower toothache.
Contraindications
Located on a bony prominence – needling should be superficial or pricking, generally 0.1–0.2 cun, avoiding deep insertion to prevent periosteal injury. Moxibustion is commonly used. Use with caution in pregnant women.
