癣病的临床表现主要有六种类型，其根本原因多由风、热、湿、虫邪所致。具体包括干癣、湿癣、风癣、牛皮癣、松皮癣和刀癣，其中春季易发的面部癣病常被称为桃花癣。
【注释】此病总因风热湿邪侵袭皮肤，日久郁结导致风气偏盛，进而化生为“虫”（指致病微生物或病理产物），因此患者会感到无休止的瘙痒。该病共有六种名称：一是干癣，搔抓后出现白色皮屑，皮肤干燥枯萎；二是湿癣，搔抓后有黏稠液体渗出，浸淫扩散形状如虫行；三是风癣，即多年不愈的顽固性癣病，搔抓后感觉麻木迟钝，不知疼痛与瘙痒；四是牛皮癣，皮损形态如同牛颈部的皮肤，厚实且坚硬；五是松皮癣，皮损形态如同苍老的松树皮，红白斑点相连，时常瘙痒；六是刀癣，皮损轮廓模糊不清，纵横分布没有定形。治疗上总体应以杀虫、渗湿、消毒的药物外敷为主。病情较轻者使用羊蹄根散，病程长久顽固者使用必效散涂抹。也有因脾、肺风湿过盛导致肿胀疼痛的情况，适宜服用散风苦参丸，以疏散风湿，肿痛即可消除。此外还有面部的风癣，初期像粟米大小，或者逐渐形成细小疮疡，时常伴有痛痒感，多发于春季，又名为吹花癣，也就是民间所说的桃花癣，女性多见。此病由肺、胃风热随阳气上升而引发，适宜服用疏风清热饮，外用消风玉容散，每日清洗患处自然见效。

The clinical manifestations of tinea (Xuan) mainly include six types, with root causes generally attributed to Wind-Heat, Dampness, and Parasites (Chong). These specifically include Dry Tinea, Wet Tinea, Wind Tinea, Psoriasis-like Tinea (Niu Pi Xuan), Pine Bark Tinea (Song Pi Xuan), and Knife-shaped Tinea (Dao Xuan). Among them, the facial tinea occurring in spring is often referred to as Peach Blossom Tinea.
[Note] This condition is generally caused by Wind-Heat-Damp pathogens invading the skin. After prolonged stagnation, Wind becomes excessive and transforms into "Parasites" (referring to pathogenic microorganisms or pathological products), resulting in incessant itching. There are six specific names: First, Dry Tinea, where scratching produces white scales and the skin appears dry and withered; Second, Wet Tinea, where scratching exudes sticky fluid that spreads and resembles worm tracks; Third, Wind Tinea, which refers to chronic, stubborn tinea unhealed for years, characterized by numbness and insensitivity to pain or itch upon scratching; Fourth, Niu Pi Xuan (Psoriasis-like Tinea), where lesions resemble the thick and hard skin of a cow's neck; Fifth, Song Pi Xuan (Pine Bark Tinea), where lesions resemble the bark of an old pine tree, with connected red and white spots and frequent itching; Sixth, Dao Xuan (Knife-shaped Tinea), where lesion contours are indistinct and distribution is irregular without fixed shape. The general treatment principle involves applying herbs that kill parasites, drain dampness, and detoxify externally. For mild cases, Yangti Gen San (Shepherd's Purse Root Powder) is used; for chronic and stubborn cases, Bixiao San (Surely Effective Powder) is applied topically. In some cases where Spleen and Lung Wind-Dampness are excessive, leading to swelling and pain, Sanfeng Kushen Wan (Wind-Dispersing Sophora Pill) is suitable to disperse Wind-Dampness, thereby resolving swelling and pain. Additionally, there is Wind Tinea on the face, initially appearing millet-sized or gradually forming small sores, accompanied by intermittent pain and itching, occurring in spring. It is also called Chuihua Xuan (Blowing Flower Tinea), commonly known as Peach Blossom Tinea, and is more common in women. This condition arises from Wind-Heat in the Lungs and Stomach rising with Yang Qi. It is suitable to take Shufeng Qingre Yin (Wind-Dispersing Heat-Clearing Decoction) internally and apply Xiaofeng Yurong San (Wind-Dispersing Jade-Face Powder) externally, washing daily for effective results.
