起发时先看头上，旋视手足透发如何。若手足尖出到，额上皆明，此毒瓦斯得泄，脾胃素强，不必虑也，

在疹子起发阶段，首先观察头部，随即查看手足部位的透发情况。如果手足指尖出疹，额头明亮清晰，这说明毒邪得以宣泄，患者脾胃功能素来强健，无需担忧，甚至不必用药即可痊愈。如果全身虽然起疹，但手足指尖未出疹，这是毒邪郁结于脾胃所致。因为人体一身之中，脾胃为君主之官，随后将精气灌溉于四肢。如今脾胃津液运行不畅，毒邪无法宣泄，所以疹子起发不到手足，这是根本动摇、枝叶枯萎的征兆。天庭（前额）也是关键部位，一定要透发出来；如果太阳经和太阴经所主的两颧及鼻子左右两侧不出疹，这就不同于金木不分那种尚可挽救的病证了。
疹子发出之后，若被风寒邪气侵袭肩窝和手臂，导致毒火凝滞不散，就会引起持续不断的疼痛，手臂不能摇动，后期必然发生壅塞肿胀。在降火解毒的药物中加入羚羊角、青皮、桔梗、独活、川芎，以此治疗可以痊愈。
口渴，是因为胃中有热，津液被热邪耗伤，所以出现口渴想喝水的症状。适宜用炒米、绿豆、芝麻煎茶给患者饮用，千万不要直接饮水，待病情回退后需加入石膏、知母、麦冬、款冬花、天花粉、葛根，以生津液而止渴。津液在三焦中流通，用以制约火热。火气上炎，熏灼心脾，导致津液下陷，口腔（华池）干涸，所以发生口渴，治疗应当清肃肺金。《内经》说：烈火刑克肺金，导致咽燥口渴，火气清除则口腔自然滋润。咽喉干燥则口渴，虽然有虚实之分，但都属于肺病。金生水且畏惧火邪，若火邪不能输降下行，致使口腔干涸而口渴，若患者喜欢热饮厌恶冷饮，稍喝一点就停止，适宜生津液，口渴自止；若患者喜欢寒凉厌恶温热，喝一百杯都不够，适宜遏制猛烈之火，口渴自解，这是金被火熔化，火焰如炉，五脏都已枯竭，何况肺脏呢！《内经》又说：降火则口渴停止。
During the eruption phase of the rash, first observe the head, then immediately check how well the rash is emerging on the hands and feet. If the rash reaches the tips of the fingers and toes and the forehead (Tian Ting) appears bright and clear, this indicates that the pathogenic toxins are being vented, and the Spleen and Stomach were originally strong; there is no need to worry, and recovery can occur without medication. If the rash covers the whole body but does not reach the tips of the hands and feet, this signifies that the toxins are stagnating in the Spleen and Stomach. In the human body, the Spleen and Stomach serve as the sovereign organ, subsequently irrigating the four limbs. Now, since the fluids of the Spleen and Stomach cannot circulate, the toxins cannot be vented, so the eruption fails to reach the extremities. This is a sign that the root has been uprooted, leading to the withering of the branches. The Tian Ting (forehead) is also a critical area that must erupt; if the areas governed by the Taiyang and Taiyin meridians—specifically the cheeks and the sides of the nose—do not erupt, this condition differs from "Metal and Wood not distinguished" patterns and may not be salvageable.
After the rash has emerged, if invaded by Wind-Cold pathogens affecting the shoulder hollows and arms, the toxic fire stagnates and fails to dissipate, causing unceasing pain and immobility of the limbs. Later, this will inevitably lead to swelling and obstruction. Adding Antelope Horn (Lingyang Jiao), Green Tangerine Peel (Qing Pi), Platycodon Root (Jie Geng), Angelica Pubescens Root (Duhuo), and Szechuan Lovage Rhizome (Chuanxiong) to the formula for reducing fire and detoxifying can cure the condition.
Thirst occurs because there is heat in the Stomach, and the Body Fluids are consumed by the heat, leading to thirst and a desire to drink. It is appropriate to brew tea with stir-fried rice, Mung Bean, and Sesame Seed for the patient to drink; direct water intake should be strictly avoided. Once the acute phase recedes, add Gypsum (Shi Gao), Anemarrhena Rhizome (Zhi Mu), Ophiopogon Tuber (Maidong), Fritillaria Bulb (Donghua), Trichosanthes Root (Huafen), and Kudzu Root (Gegen) to generate fluids and stop thirst. The fluids circulate through the Sanjiao (Triple Burner) to control the fire. When Fire Qi flares upward, it scorches the Heart and Spleen, causing the fluids to sink and the oral cavity (Hua Chi) to dry up, resulting in thirst. Treatment should focus on clearing Metal (Lungs). The Classic states: "Fierce fire punishes Metal, causing dry throat and thirst; once the fire is cleared, the Hua Chi naturally moistens." Dryness of the throat leads to thirst; whether due to deficiency or excess, it belongs to Lung disease. Metal generates Water and fears Fire; if Fire cannot descend and transmit downward, causing the Hua Chi to dry up and induce thirst, one should distinguish the pattern. If the patient prefers hot drinks and dislikes cold, drinking only a little before stopping, it is suitable to generate fluids, and the thirst will cease spontaneously. If the patient prefers cold and dislikes heat, drinking hundreds of cups is insufficient, it is necessary to restrain the fierce fire, and the thirst will resolve spontaneously. This indicates that Metal is being melted by Fire, the flames are like a furnace, the Five Zang organs are exhausted, let alone the Lungs! The Classic further states: "Reducing the fire stops the thirst."
