喉癣的症状是咽喉干燥，并生出类似苔藓的病变。初期表现为瘙痒，随后加重为燥裂和疼痛。若过量饮用药酒及食用辛辣刺激性食物（五辛），会导致患处腐烂扩大，呈现出如同蚂蚁蛀蚀般的孔洞形状。
【注释】此病证又名“天白蚁”。主要症状为咽喉干燥。起初感觉瘙痒，继而长出苔藓样病变，颜色暗红且质地僵硬，伴有燥裂和疼痛，时常吐出有臭味的涎液，影响饮食。这是由于过食煎炸烧烤、药酒以及葱蒜韭菜等辛辣食物，导致热邪积聚于胃，胃火向上熏蒸肺脏而引发此病。适宜服用广笔鼠粘汤；病灶未溃烂时吹敷矾精散，已溃烂时吹敷清凉散。患者需清心寡欲，忌食浓厚滋味及发物，如此或许能治愈一二；如果失治且调理不慎，会导致霉烂扩散，范围扩大，层层堆积腐肉，旁边生出小孔，状如蚂蚁蛀蚀，大多难以救治。

Throat lichen (Hou Xuan) is characterized by dryness of the throat and the growth of moss-like lesions. Initially, there is itching, which subsequently worsens into dryness, cracking, and pain. Excessive consumption of medicinal wine and pungent/spicy foods (Wu Xin) can cause the affected area to rot and spread, presenting with hole-like shapes resembling ant burrows.
[Note] This condition is also known as "Tian Bai Yi" (Heavenly White Ant). The main symptoms include dryness of the pharynx and esophagus. It begins with a sensation of itching, followed by the emergence of moss-like lesions that are dark red in color and hard in texture, accompanied by dryness, cracking, and pain. There is often expectoration of foul-smelling saliva, which interferes with eating and drinking. This disease arises from overconsumption of fried, roasted, or grilled foods, medicinal wine, and pungent vegetables (such as garlic, scallions, and chives), leading to the accumulation of heat in the Stomach. Stomach fire then steams upward to affect the Lungs, causing this ailment. It is appropriate to take Guangbi Niuniang Decoction; if the lesion has not ulcerated, apply Fanjing San powder via insufflation; if it has ulcerated, apply Qingliang San powder via insufflation. The patient should cultivate a calm mind, reduce desires, and avoid rich flavors and triggering foods (Fa Wu); under such conditions, recovery may be possible in some cases. If treatment is neglected and care is improper, rotting and decay will spread and enlarge, with layers of necrotic tissue accumulating and small holes forming on the sides, resembling ant burrows. Such cases are mostly incurable.
