Phlegm pouch

痰包 〔痰包〕 tán bāo

Also gourd tongue. A swelling on the under surface of the tongue shaped like a gourd, smooth and soft to the touch, and yellow in color. Phlegm pouch hampers eating and speech. When it bursts, it exudes a thick sticky phlegm-like substance similar to egg-white and sometimes like soy-bean dregs. It tends to recur and resist healing.

Biomedical correspondence: ranula (sublingual ptyalocele).

Management: It should be cut open with sharp scissors to allow the pus to drain. Borneol and Borax Powder (冰硼散 bīng péng sǎn) should be applied by insufflation, and heat-clearing phlegm-transforming formulas such as Two Matured Ingredients Decoction (二陈汤 èr chén tāng) plus coptis (Coptidis Rhizoma, 黄连 huáng lián), scutellaria (Scutellariae Radix, 黄芩 huáng qín), bamboo shavings (Bambusae Caulis in Taenia, 竹茹zhú rú), and dandelion (Taraxaci Herba, 蒲公英 pú gōng yīng) should be prescribed as oral medication.
