之，所以名曰虎潜。今人用别骨者，则非虎潜之义也。也。

（梁上尘，又名乌龙尾）药性平和，略带寒凉。无毒。采集时须远离烟火之处，务必在堂殿中间收集。用扫帚拂下后随即收拢，经过筛罗过滤后方可使用。对于中恶突然发作导致的鼻出血，滴流不止者，有显著功效；对于伤寒阳毒引起的发斑，伴有异常烦躁口渴者，能立即见效。（张仲景的黑奴丸，使用此药即可治疗此类病症。）主治腹内疼痛噎塞，消除头部的软疮。另外，老屋上的灰尘煤渣，可治疗牙龈肿痛出血。因此，取茅草屋顶上的灰尘，多用于去除咳嗽症状。（与石黄、款冬花、妇女月经期的衣带一起研成粉末，用水调和涂抹在茅草上，待干燥后纳入竹筒中，通过口吸入咽下，没有不痊愈的。）
虎骨
味辛，气微热。无毒。各地山林都有，颜色发黄且为雄性的为佳。必须确认不是被药箭射伤致死（被药箭射死的，不可入药。恐怕药毒浸透到骨血之间，非常害人，必须得到网捕杀死的才可使用）。刚获取时需涂抹酥油炙烤至脆。不要煎煮汤液，只制成散剂或丸剂。需要知晓与之相畏的三种药物：蜀漆、蜀椒、磁石。用于治疗风痹，是因为虎啸则风从（象征木被金制）；用于补益膝部酸痛，只因为老虎行走时腿部有力健壮。杀灭疰病邪气，停止上焦惊悸，宜求取头骨；坚固筋骨，缓解下肢风痛，宜寻觅胫骨。眼睛可用于收敛定止咬伤疮毒，胆囊主治小儿疳积痢疾及惊痫。威骨位于胁部两侧（虎的威骨形状如“乙”字，长一寸，破肉取出。尾部末端也有，但不如胁部的为好），佩戴它能每日增加威势。虎眼形状像白石（凡是老虎夜间视物，一只眼睛放光，一只眼睛看物。猎人等候时机射击，弩箭刚到，目光便随着坠落在地。得到的虎眼，形状像白石），得到它的人夜晚可以独自行走休息。皮毛驱除邪气、截断疫疟非常灵验，食用肌肉，增强体力、止呕恶尤其有效。将虎鼻悬挂在门户上方主生男孩（孕妇将虎鼻悬于门户上，主生男），癫疾也能治疗；虎屎封贴疮口美观，长期食用对人有益。种类繁杂，赤白不同，形体小巧凶猛敏捷尤为厉害。猎者通过网捕，有时也能获得。安五脏，补绝伤。强筋力，壮胆志。正月不要食用（正月建寅，所以忌讳食用虎豹肉），违反则会损伤精神。油脂涂抹头发即能生长，鼻辟邪气立即驱遣。头骨烧灰淋汁，洗头可彻底去除头皮白屑。皮用作裘皮，可抵御寒冷。
（陈嘉谟）按语：古人创立虎潜丸，方中使用虎胫骨一味药，其道理非常幽雅深远。盖因虚金属阴，风木属阳。虎啸风从，乃是木被金制的结果，这是必然的道理。所以凡是脚膝拘挛、痈痪酸痛等证候，使用虎骨调治，就能追风定痛。这又是阴出阳藏的意义啊。况且老虎全身的筋节力气，都出自前足的胫骨中。因为其性气都藏于其中，人们经常使用它，所以命名为虎潜。现在人使用其他骨头，就不符合虎潜的含义了。第十一卷龙骨条目之后，所引用的《卫生宝鉴》宜参考阅读。
(Liang Shang Chen, also known as Wulong Wei) The nature is neutral, slightly cold. Non-toxic. It must be collected far from fire and smoke sources, specifically in the center of halls and palaces. After sweeping it down with a broom, collect it immediately, pass it through a sieve, and then use it. It shows remarkable efficacy for sudden epistaxis caused by Zhong E (sudden evil invasion); it produces immediate effects for macules appearing due to Yang Du (yang toxicity) in Shang Han (Cold Damage), accompanied by extreme restlessness and thirst. (Hei Nu Wan [Black Slave Pill] by Zhang Zhongjing uses this herb to treat such conditions.) It governs abdominal pain and dysphagia, and resolves soft sores on the head. Additionally, dust and coal from old houses can treat swollen and bleeding gums. Therefore, dust from thatched roofs is often used to eliminate coughs. (Mixed with Shi Huang [Mineral Yellow], Kuandonghua [Flos Farfarae], and menstrual cloths from women into powder, mixed with water, applied to thatch, dried, placed in a bamboo tube, and inhaled/swallowed, recovery is assured.)
Hu Gu (Tiger Bone)
The taste is pungent, the nature is slightly hot. Non-toxic. It is found in forests and mountains everywhere; those that are yellow and from male tigers are superior. One must verify that the tiger was not killed by poisoned arrows (those killed by poisoned arrows cannot be used medicinally, as the poison may permeate the bone and blood, harming humans greatly; only those killed by nets should be used). Upon acquisition, coat with su (clarified butter) and roast until crisp. Do not decoct into liquid; prepare only as powders or pills. Be aware of three substances with which it is incompatible: Shuqi (Radix Bupleuri Preparata), Shujiao (Fructus Zanthoxyli), and Cishi (Magnetitum). It treats Feng Bi (Wind-Damp Bi syndrome) because the tiger's roar summons wind (symbolizing Wood being controlled by Metal); it tonifies soreness in the knees because the tiger walks with powerful legs. It kills Zhu pathogenic factors (chronic infectious diseases), stops palpitations in the Upper Jiao (Upper Burner), for which the skull is sought; it strengthens sinews and bones, relieves Wind-Pain in the lower body, for which the tibial bone is suitable. Eyes are collected to settle and resolve toxic sores from bites; gallbladders govern pediatric Ganji (malnutrition) and dysentery, as well as convulsions and epilepsy. Weigu (Vitality Bone) is located on both sides of the ribs (The tiger's vitality bone resembles the character "Yi" [乙], one cun long, obtained by breaking the flesh. There is also one at the tail tip, but inferior to the rib one). Carrying it daily increases one's prestige. Tiger eyes resemble white stones (When tigers see at night, one eye emits light while the other observes objects. Hunters wait and shoot; when the arrow arrives, the gaze falls to the ground. Obtained eyes resemble white stones). Those who possess them can walk and rest alone at night. Fur repels evil and cuts off epidemic malaria effectively; consuming muscle enhances strength and stops nausea particularly well. Hanging the nose above the door predicts the birth of a son (Pregnant women hanging a tiger nose above the door main the birth of a male child); it still treats Dianji (epilepsy); sealing sores with feces beautifies them, and long-term consumption benefits people. Species are numerous, differing in red and white colors; forms are small, fierce, and agile. Hunters sometimes obtain them via netting. It calms the Five Zang organs, repairs severe injuries. Strengthens sinews and force, fortifies gallbladder willpower. Do not consume in the first lunar month (The first month corresponds to Yin [Tiger], hence taboo against eating tiger and leopard meat); violating this damages the Shen (Spirit). Fat applied to hair promotes growth; the nose repels evil spirits immediately. Skull ash leached with water, used for washing hair, completely removes dandruff. Fur made into coats wards off cold.
(Chen Jiamo) Commentary: The ancients established Hu Qian Wan [Tiger Stealth Pill], using only Hu Jing Gu (Tibial Bone of Tiger) in the formula; its principle is profound and elegant. Essentially, Xu Jin [deficient Metal] belongs to Yin; Feng Mu [Wind-Wood] belongs to Yang. The tiger's roar summoning wind demonstrates Wood being controlled by Metal, which is inevitable. Thus, for conditions such as stiffness and cramping of feet and knees, and painful swelling, using bone to regulate can chase away wind and stop pain. This embodies the meaning of Yin emerging from Yang storage. Moreover, all the tendons, joints, and strength of the tiger originate from the tibial bones of the front paws. Because its nature and Qi are stored within, people frequently use it, hence named "Tiger Stealth." If modern practitioners use other bones, they do not conform to the meaning of Tiger Stealth. Refer to the citation of *Weisheng Baojian* [Precious Mirror of Health] after the Long Gu [Dragon Bone] entry in Volume 11.
