A woman who was obese and suffered from qi stagnation presented with tongue numbness, dizziness, numbness in the hands and feet accompanied by a sensation of qi blockage, phlegm accumulation, and constipation. She was treated with Liangge San (Cooling the Diaphragm Powder) added with Nanxing (Arisaematis Rhizoma), Xiangfu (Cyperi Rhizoma), and Taixiong (Ligusticum Chuanxiong). (Danxi Xinfa)
In cases where the tongue experiences spontaneous bi-syndrome (obstruction/numbness) without obvious cause, it should not be treated as a wind-pathogen disease. This condition arises from insufficiency of Heart blood. Use Lizhong Tang (Regulate the Middle Decoction) added with Shufu (Prepared Aconiti Lateralis Radix, half a qian) and Danggui (Angelicae Sinensis Radix, one and a half qian). (Yijia Si Yaojue) [Note: Tongzhi records it as Lizhong Tang combined with Siwu Tang.]
Shunqi Huotan Tang (Smooth Qi and Resolve Phlegm Decoction) treats tongue bi-syndrome or numbness. This is caused by phlegm and qi stagnation in the Pericardium collateral.

(Tongzhi) Zhimaxiaotanyin (Numbness-Resolving Phlegm-Draining Drink) from Chuishui Xuanzhu treats numbness of the mouth and tongue that extends to the corners of the mouth and the head/face. In Huotan Tang, remove Banxia and Xiangfu, and add Huangqin (Scutellariae Radix), Nanxing (Arisaematis Rhizoma, boiled thoroughly with Baifan, Zaorao, and Shengjiang), Tianma (Gastrodiae Rhizoma), and Xixin (Asari Radix et Rhizoma).
