Also invisible worm sore of the genitals. From The Divine Farmer’s Roots and Grasses Classic (神农本草经 shén nóng běn cǎo jīng). Erosion of the genitals arising when affect-mind depressed fire damages the liver and spleen, causing damp-heat to pour downward to the lower body, where it lies depressed and steams, thereby engendering worms. Genital erosion is characterized by ulceration of the external genitals exuding pus and blood, possibly with itching and soreness, swelling, and sagging sensation. It is usually associated with red and white vaginal discharge and dribbling urination.
Medicinal therapy: Clear heat, disinhibit dampness, and kill worms. Use Fish Poison Yam Dampness-Percolating Decoction (萆薢渗湿汤bì xiè shèn shī tāng). Decoct Itch-Soothing Decoction (塌痒汤tā yǎng tāng) as a steam-wash.
