红色的小点，有颗粒状物隐藏在皮肤之中而不显露出来，这就是血箭的症状。此证属于心火损伤血液，血液不能正常散播而郁积于皮肤所致，治疗以四物消风饮为基础，去掉柴胡，加入连翘、木通为主方。
多发生于颈部、胸部和腋窝之间，颜色呈紫色或白色，点点相连成片，像粗糙的皮肤一样，但不会蔓延扩散，也没有疼痛或瘙痒感。这是由于邪风侵入肌肤，停留日久不散而形成的。治疗使用加味二陈汤，加入荆芥、防风、蝉蜕各二钱，川芎一钱，用酒和水各半煎服。外用荆芥煎汤清洗患处，并敷上雄蛇散即可痊愈。
将雄黄（一钱）和蛇蜕（一条，保留药性，煅存性）共同研磨成细末，用麻油调和后涂抹。
初起时斑点游走并连成片，时间久了可蔓延至全身，起初没有疼痛或瘙痒，久了会有轻微瘙痒。这是因为汗湿的衣服经过日晒后接触身体，或者带着汗水在阳光下行走所致，待斑点变黑消退后就会痊愈。虽然古方中治疗此证的方剂很多，但见效的很少。患此证的人忌食鱼腥、烈性酒以及容易引发风邪的食物。
将雄黄、硫黄、黄丹、密陀僧、天南星研磨成细末。先用葱擦拭患处，再用生姜蘸取药末擦拭，擦拭后患处逐渐变黑，直到黑色消散则痊愈。
皮肤干燥瘙痒，起疹子如疥疮般但颜色发白，搔抓后皮屑脱落，逐渐导致肢体干枯开裂，出血且疼痛，十指间的皮肤增厚而无法活动。可用生猪脂涂抹患处。
血液从毛孔中射出如同箭矢一般，这是由于心肺火气旺盛，逼迫血液妄行于体外所致，适宜服用凉血地黄汤，外用一片生猪肉贴敷在患处，血液即可停止。或者用京墨研成粉末，用醋调匀涂抹也能治愈。
取生地（三到五钱）、黄连（一钱）、当归（一钱五分）、甘草、栀子、元参、黄芩（各一钱五分）。用水两钟，煎至八分。根据病位的上下，在饭前或饭后服用。
Tiny red spots, with granular structures hidden within the skin without protruding, constitute this condition. It belongs to Heart Fire damaging the blood, causing the blood to fail in its normal circulation and accumulate in the skin. The primary treatment is Siwu Xiaofeng Yin (Four Substances Wind-Dispersing Decoction), modified by removing Chaihu (Bupleuri Radix) and adding Lianqiao (Forsythiae Fructus) and Mutong (Akebiae Caulis).
It commonly occurs between the neck, chest, and axillae. The color is purple or white, with dots connecting into patches resembling rough skin, yet it does not spread or migrate, nor is there pain or itching. This arises from pathogenic wind invading the muscle layer, lingering for a long time without dispersing. Treatment utilizes Jiawei Erchen Tang (Modified Two-Aged Phlegm Decoction) with added Jingjie (Schizonepetae Spica), Fangfeng (Saposhnikoviae Radix), and Chanyi (Cicadae Periostracum), each 2 qian, and Chuanxiong (Ligustici Chuanxiong Rhizoma) 1 qian, decocted with half wine and half water. Externally, wash the area with a decoction of Jingjie and apply Xionshe San (Realgar and Snake Molt Powder) for cure.
Grind Xionghuang (Realgar, 1 qian) and Shetui (Snake Molt, one strip, processed to retain efficacy) into fine powder. Mix with sesame oil and apply topically.
Initially, the spots wander and merge into patches; over time, they may extend over the entire body. Initially free of pain or itching, slight itching develops later. This results from sun-dried sweat-soaked clothes contacting the body, or walking in the sun while sweating. The condition resolves when the spots turn black and fade away. Although many ancient formulas exist for treating this syndrome, few are effective. Patients should avoid fish, seafood, strong alcohol, and foods that trigger wind.
Grind Xionghuang (Realgar), Liuhuang (Sulfur), Huangdan (Lead Monoxide), Miduoseng (Lead Carbonate), and Nanting (Arisaematis Rhizoma Praeparatum) into fine powder. First rub the affected area with green onion, then apply the powder using ginger slices. The area will gradually turn black; continue application until the blackness dissipates for a cure.
The skin is dry and itchy, presenting with eruptions like eczema but white in color. Scratching causes scaling. Gradually, the limbs become dry, cracked, bleeding, and painful. The skin between the fingers thickens, impairing movement. Apply raw lard topically.
Blood shoots out from the pores like arrows due to excessive Fire in the Heart and Lung, forcing blood to circulate recklessly outward. Internally, administer Liangxue Dihuang Tang (Cooling Blood and Rehmannia Decoction). Externally, apply a slice of fresh pork to stop the bleeding. Alternatively, grind Jingmo (Beijing Ink Stick) into powder, mix with vinegar, and apply topically for cure.
Take Shengdi (Rehmanniae Radix, 3–5 qian), Huanglian (Coptidis Rhizoma, 1 qian), Danggui (Angelicae Sinensis Radix, 1.5 qian), Gancao (Glycyrrhizae Radix et Rhizoma), Zhizi (Gardeniae Fructus), Yuanshen (Scrophulariae Radix), and Huangqin (Scutellariae Radix, each 1.5 qian). Add two zhong of water and decoct to obtain eight fen. Take according to the location of the disease (upper or lower body) and timing relative to meals.
