辛平苦毒。破僻积治蛊消瘀。阴蚀虫疮。有野狼牙煎熏洗涤。（野狼毒辛苦平。大毒。虽
有破积杀虫逐痰行血之功。然毕竟非内服之品。只可外治虫癣等证。或洗或搽可也。野狼牙苦
寒大毒。其根形如牙。本经虽有除热杀虫诸功。然亦如野狼毒之外用不宜内服也。）
（李时珍曰。木者。五行之一也。性有宜土宜山原隰之不同。禀有或乔或香苞寓之殊异。
是以坚脆美恶。同含太极之情。因之色味性形。各赋方宜之质。材充药品。业医者固当预悉
其寒温。实备果疏。卫生者岂可不审其良毒也哉。）
\r槐花\pq70.bmp\r
禀天地阴凝之气。凉血清肝。除下焦湿热之邪。祛风疗痔。虚寒当戒。角则降且通肠
。酸苦宜知。花可散而达表。（槐花花与实性味虽同。主治略异。花色黄质轻。能入手足阳
明血分。凉而带散。故治肠风痔漏之外。又能治痈疽毒疮。皮肤风湿等证。槐角则所结之子
也。色紫质重。但入肝与大肠。下降之力为多。故治肠风痔漏之外。兼治崩带下血。由于下
焦血分有热者。皆可用之。）
苦寒坚肾。泻相火以制阳光。辛燥入阴。除湿热而安下部。（黄柏其质虽皮。其气味
皆苦寒沉降。故独入肾与膀胱。清泄下焦湿火。而安肾水。至所以治口疮。清肺部上焦之热
者。即用皮意。究非专治之药。虽清上而仍赖其降下耳。）
【野狼毒】味辛、性平，有毒。能破除积聚，治疗蛊毒，消除瘀血。用于阴部蚀疮及虫疮，可用野狼牙煎汤熏洗或洗涤。（野狼毒味辛、苦，性平，有大毒。虽然具有破除积滞、杀虫、逐痰、行血的功效，但终究不是内服的药物，仅可用于外治虫癣等证，或者清洗或者涂抹即可。野狼牙味苦，性寒，有大毒，其根部形状像牙齿。《神农本草经》中虽有清除热邪、杀虫等多种功效，但也如同野狼毒一样，只宜外用，不宜内服。）
（李时珍说：木，是五行之一。其性质有适宜生长在土中、山中、平原或低湿之地的不同；禀受的气有高大乔木或低矮灌木、芳香或无味的差异。因此，木材的坚硬与脆软、美好与恶劣，都蕴含着太极生成的情态。依据其颜色、味道、性质和形态，各自赋予了适应特定环境的质地。作为充任药品的材料，从事医学的人固然应当预先了解其寒温属性；实际上作为果蔬储备，注重养生的人难道可以不审慎辨别其优劣与毒性吗？）
槐花
禀受天地间阴凝之气。能凉血、清肝。清除下焦湿热之邪。祛风、治疗痔疮。虚寒体质者当忌用。槐角则具有下降且通利肠道的功效。酸苦之味需知晓。槐花可发散并透达体表。（槐花的花与果实性质味道虽然相同，主治略有差异。槐花色黄质轻，能进入手足阳明经的血分，凉而带有发散之性，所以除了治疗肠风痔漏之外，又能治疗痈疽毒疮、皮肤风湿等证。槐角则是槐树结出的种子，色紫质重，只进入肝经与大肠经，下降的力量较多，所以除了治疗肠风痔漏之外，兼治崩漏、带下出血，由于下焦血分有热导致的病症，都可以使用。）
【黄柏】味苦，性寒，能坚肾。泻相火以制约阳光（亢盛之火）。味辛燥入阴分，除湿热而安定下部。（黄柏虽然质地是树皮，但其气味皆苦寒沉降，所以独入肾经与膀胱经，清泄下焦湿火，从而安固肾水。至于用它来治疗口疮，清除肺部上焦的热邪，只是借用皮类药材宣散之意，究其根本并非专门治疗上焦的药物，虽然是清上焦热，但仍依赖其降下的特性罢了。）
[Wild Langdu] (Stemmate Bark)
Acrid in flavor, neutral in nature, and toxic. It can break up accumulations, treat gu poison (parasitic disease), and eliminate blood stasis. For erosive sores of the yin organs and parasitic skin ulcers, a decoction of Wild Langya (Stemmate Root) can be used for fumigation and washing. (Wild Langdu is acrid and bitter, neutral in nature, and highly toxic. Although it possesses the efficacy of breaking down accumulations, killing parasites, driving out phlegm, and promoting blood circulation, it is ultimately not suitable for internal use. It may only be used externally to treat conditions such as parasitic tinea, either by washing or applying topically. Wild Langya is bitter, cold in nature, and highly toxic; its root resembles teeth. Although the *Shennong Bencao Jing* mentions various functions such as clearing heat and killing parasites, like Wild Langdu, it is also suitable only for external use and not for internal administration.)
(Li Shizhen stated: Wood is one of the Five Elements. Its nature varies depending on whether it prefers soil, mountains, plains, or low-lying wetlands. The qi it inherits differs between tall trees and shrubs, aromatic and non-aromatic varieties. Thus, whether hard or brittle, fine or coarse, all contain the sentiment of Taiji. Based on their color, flavor, nature, and form, they are endowed with qualities suited to specific environments. As materials for medicinal use, practitioners must certainly understand their cold and warm properties beforehand. Indeed, even if stored as fruits and vegetables, those concerned with health preservation should not fail to carefully examine their quality and toxicity.)
Huaihua (Sophorae Flos)
It inherits the yin-condensing qi of heaven and earth. It cools the blood and clears the liver. It eliminates damp-heat pathogens from the lower jiao. It dispels wind and treats hemorrhoids. Those with deficiency-cold patterns should avoid it. Huaijiao (Sophorae Fructus Immaturus) has descending and bowel-unblocking properties. One must understand its sour and bitter flavors. The flower can disperse and reach the exterior. (Although the flower and fruit of Sophora have similar nature and flavor, their primary indications differ slightly. Sophora flowers are yellow and light in texture, entering the blood aspect of the Foot and Hand Yangming meridians. Being cool with dispersing properties, besides treating intestinal wind and hemorrhoidal bleeding, they can also treat carbuncles, sores, toxic ulcers, and skin wind-dampness. Huaijiao refers to the seeds borne by the tree; they are purple and heavy in texture, entering only the Liver and Large Intestine meridians. Their descending power is predominant. Therefore, besides treating intestinal wind and hemorrhoidal bleeding, they also treat metrorrhagia, leukorrhea with bleeding, and conditions due to heat in the blood aspect of the lower jiao, all of which can be treated with them.)
Huangbai (Phellodendri Cortex)
Bitter and cold; it consolidates the Kidney. It drains ministerial fire to control excessive yang. Acrid and drying, it enters the yin aspect, eliminating damp-heat and calming the lower body. (Although Huangbai is bark in texture, its flavor and nature are bitter, cold, and sinking. Thus, it enters exclusively the Kidney and Bladder meridians, clearing and draining damp-fire from the lower jiao, thereby stabilizing Kidney water. Regarding its use to treat mouth ulcers and clear heat from the Lung and upper jiao, this merely borrows the dispersing intent of bark-type herbs; fundamentally, it is not a specialized drug for the upper jiao. Although it clears the upper, it still relies on its descending action.)
