（即血竭。凡使用血竭时，需先研磨成粉末并筛过，用于丸药和散剂中。如果与其他药物一起捣碎，它就会化作灰尘飞散。）
【气味】
味甘、咸，性平，无毒。
【主治】
心腹突然疼痛，金创出血，破除瘀血以止痛生肌，去除五脏邪气，跌打损伤，各种疼痛，气血搅动刺痛，内伤导致的血聚，补虚损，均宜用酒送服。补益心包络及肝血不足，增益阳精，消除阴滞之气，外敷治疗一切恶疮、疥癣久不愈合之症。性情急躁者不可多用，能引脓外出，消散滞留之血及各类疼痛。治疗妇人血气病，小儿抽搐痉挛。李时珍说：骐竭是树木的脂液，就像人的膏血一样，其味甘甜咸涩而走血分，大概是手足厥阴经的药物。因为肝与心包都主司血液的缘故。河间刘氏说：血竭能除去血痛，是和血的圣药，这话是对的。乳香、没药虽然主治血病，但兼入气分；此药则专入血分。
（各种蛇的鼻子都是向下的，唯独这种蛇的鼻子向上。背部有方胜花纹，因此得名。头尾各有一尺长的有毒，不可使用。去掉皮骨，换酒浸泡三天，用火炙烤去尽皮骨。此物毒性很大，不可不防备。炙烤后收藏则不生虫蛀。其骨刺必须远远丢弃，会伤人，毒性同于活体。）
【气味】
味甘、咸，性温，有毒。（得酒效果更佳。）
【主治】
中风湿痹导致的感觉麻木，筋脉拘挛紧急，口眼歪斜，半身不遂，骨节疼痛，脚弱不能久立，暴风瘙痒，大风疥癣，治疗肺风鼻塞，浮风瘾疹，身上白癜风、溃疡斑点。通治各种风证，破伤风，小儿风热急惊风、慢惊风抽搐痉挛，瘰疬漏疾，杨梅疮，痘疮倒陷。蛇性窜动，能引导药力到达有风疾的部位，所以能治风。而花蛇又食用石南，所以能透骨搜风，截断惊风定止抽搐，是治疗风痹、惊搐、癞癣、恶疮的要药。取其内走脏腑，外彻皮肤，无处不到。凡是服用蛇酒药，切忌见风。
(That is Xuejie [Dragon's Blood]. When used, it must first be ground into powder and sifted for use in pills and powders. If pounded together with other herbs, it will turn to dust and fly away.)
[Flavor and Properties]
Sweet, salty, neutral, non-toxic.
[Indications]
Sudden pain in the heart and abdomen; bleeding from metal wounds; breaking up accumulated blood to stop pain and promote flesh regeneration; eliminating pathogenic qi from the five zang organs; traumatic injuries from falls or blows; all kinds of pain; stabbing pain caused by chaotic blood and qi; internal injury resulting in blood accumulation; tonifying deficiency. All should be taken with wine. Tonifies the pericardium collateral and insufficient liver blood; benefits yang essence; eliminates stagnant yin qi; applies externally to treat all malignant sores, scabies, and tinea that fail to heal over a long period. Those with an impatient temperament should not use it excessively. It draws out pus, disperses stagnant blood and various pains. Treats women's blood and qi disorders, and pediatric convulsions and spasms. Li Shizhen said: Qijie (Xuejie) is the resinous fluid of trees, similar to human marrow and blood. Its sweet and salty flavor enters the blood level. It is likely a herb for the Foot-Shaoyin and Hand-Shaoyin meridians. Since the Liver and Pericardium both govern blood, this is why. Liu Wansu of Hejian stated: "Xuejie removes blood-related pain and is the holy medicine for harmonizing blood." This is correct. Ruxiang [Frankincense] and Moyao [Myrrh], although they treat blood diseases, also enter the qi level; this herb, however, specializes in the blood level.
(All snakes have noses pointing downward, but this snake's nose points upward. It has square-patterned markings on its back, hence its name. The head and tail sections, each one chi long, are highly toxic and should not be used. Remove the skin and bones, soak in wine for three days, then roast over fire until all skin and bones are removed. This substance is very toxic and precautions are essential. After roasting, storing it prevents insect infestation. Its bone spines must be discarded far away as they can injure people; their toxicity is the same as that of the live animal.)
[Flavor and Properties]
Sweet, salty, warm, toxic. (Best when combined with wine.)
[Indications]
Wind-damp bi syndrome causing numbness; tendon and vessel contraction and stiffness; facial paralysis (deviation of mouth and eyes); hemiplegia; joint pain; weakness of the legs preventing prolonged standing; sudden itching due to wind; severe scabies and tinea; treating lung wind causing nasal congestion; floating wind urticaria; vitiligo, ulcers, and spots on the body. Generally treats all wind syndromes, tetanus, pediatric wind-heat acute and chronic convulsive disorders, and spasms; scrofula and fistulas; yaws; inverted smallpox lesions. The nature of the snake is agile and penetrating, capable of guiding medicinal properties to areas affected by wind pathogens, thus enabling the treatment of wind diseases. Furthermore, since the Flower Snake feeds on Nanaxing [Stemona root/Stemona rhizome], it can penetrate bones and search out wind, arresting convulsions and stopping spasms. It is a crucial herb for treating wind-bi, convulsions, leprosy, tinea, and malignant sores. It penetrates internally to the zang-fu organs and externally through the skin, reaching everywhere. When taking snake wine preparations, one must strictly avoid exposure to wind.
