赤白游风的症状表现为皮肤上出现如粟米大小的疹块，伴有浮肿、发热、瘙痒和疼痛。这是由于表虚导致风邪侵袭，郁结日久，血分受热而呈红色，气分受热而呈白色，热邪化生而成。
【注】此证发作于肌肤之间，游走不定，起始时形状如云片状，伴有浮肿和发热，疼痛与瘙痒并存，隆起处如同粟米。其病因在于脾肺燥热，兼有表虚导致腠理（皮肤纹理及汗孔）不紧密，风邪乘虚侵入，郁结日久，与体内热邪相互搏结，致使热势更加旺盛而形成。若病邪滞留于血分，则发为赤色；若滞留于气分，则发为白色，因此命名为赤白游风。初期均适宜使用荆防败毒散进行疏风解表治疗。发赤色的患者，随后服用四物消风饮；发白色的患者，随后服用补中益气汤，并加入防风、蝉蜕、僵蚕、生何首乌进行治疗。初期均可用牛肉片贴敷患处，猪羊肉亦可。若皮损游走速度过快，可采用砭法（刺络放血或刮治）；若皮损固定不动，可用真君妙贴散以鸡蛋清调匀后外敷。判断病情顺逆的方法，可参考丹毒门的论述。忌食鱼腥、鸡肉、鹅肉以及具有动风、燥血作用的食物，若触犯这些禁忌，则难以痊愈。

紫白癜风没有瘙痒和疼痛感，白色斑片因气机阻滞所致，紫色斑片因血液凝滞所致。若体质偏热，又受风邪侵袭并与湿气相搏，导致毛窍闭塞，从而形成斑片状皮损。
【注】此证俗称汗斑，分为紫色和白色两种。紫色是因为血行不畅（血滞），白色是因为气机运行受阻（气滞）。总归是由于体质偏热，风邪和湿气侵入毛孔，与气血相互凝滞，导致毛窍闭塞而形成的。多生长在面部和颈部，斑点游走蔓延成片，初起时无痛痒感，时间久了会有轻微瘙痒。初起时适宜使用万灵丹使其发汗，随后常服胡麻丸；外用密陀僧散擦拭患处，令其出汗，风湿之邪自然解除。古今治疗方法虽多，但见效的很少。患有此证的人应当忌食鱼腥、煎炸炒制食物、烈性酒以及具有动风、发物性质的食物。

Chi Bai You Feng (Red and White Wandering Wind) presents with skin lesions resembling millet grains, accompanied by edema, heat, pruritus, and pain. This condition arises from exterior deficiency allowing wind pathogen invasion; after long-standing stagnation, blood stasis turns red due to heat transformation, while qi stagnation turns white due to heat.
[Note] This syndrome manifests on the skin and muscles, wandering without a fixed location. It begins like cloud-like patches, featuring edema and heat, with both pain and itching coexisting, and raised areas resembling millet grains. The etiology involves dryness-heat in the Spleen and Lung, combined with exterior deficiency leading to loose Cou Li (skin texture and pores). Wind pathogens invade, stagnate for a long time, and contend with internal heat, causing the heat to intensify and form the disease. If the pathogen remains in the Blood level, it manifests as red; if it remains in the Qi level, it manifests as white, hence the name Chi Bai You Feng (Red and White Wandering Wind). Initially, Jing Fang Bai Du San (Schizonepeta and Saposhnikovia Decoction) is suitable for dispersing and resolving. For red lesions, Si Wu Xiao Feng Yin (Four Substances Wind-Extinguishing Drink) should be taken subsequently; for white lesions, Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction), added with Fang Feng (Saposhnikovia Root), Chan Tui (Cicada Slough), Jiang Can (Bombyx Batryticatus), and Sheng He Shou Wu (Prepared Polygonum Multiflorum Root), should be taken. Initially, beef slices can be applied topically to the affected area; pork or mutton are also acceptable. If the lesions wander too rapidly, Bian Fa (pricking or scraping therapy) should be used; if they remain stationary, Zhen Jun Miao Tie San (True Lord's Miraculous Pasting Powder) mixed with egg white should be applied externally. Methods for assessing favorable and unfavorable prognoses can be referred to in the Dan Du (Erysipelas) section. Avoid fishy smells, chicken, goose, and foods that stir wind or dry blood; violating these taboos will make recovery difficult.

Zi Bai Dian Feng (Purple and White Vitiligo/Mottling) lacks pruritus and pain. White spots result from Qi stagnation, while purple spots result from Blood coagulation. In constitutions with heat, invasion by wind pathogens combined with dampness obstructs hair follicles, leading to macular eruptions.
[Note] This syndrome is commonly known as "sweat spots" (Tinea Versicolor), existing in purple and white varieties. Purple is caused by Blood stagnation; white is caused by Qi stagnation. Generally, it results from heat constitution where wind pathogens and dampness invade the pores, condensing with Qi and Blood, closing the hair follicles. It mostly occurs on the face and neck, spreading in migrating spots into patches. Initially, there is no pain or itching, but mild itching may develop over time. Initially, Wan Ling Dan (Myriad Spirits Pill) should be used to induce sweating, followed by regular oral administration of Hu Ma Wan (Sesame Pill). Externally, Mi Tuo Seng San (Lead Monoxide Powder) should be rubbed onto the affected area to induce sweating, thereby resolving wind-dampness. Although ancient and modern treatments are numerous, few achieve success. Patients with this condition must avoid fishy smells, fried foods, strong alcohol, and foods that stir wind or trigger outbreaks.
