【川黄柏】
味苦，性寒。归足厥阴肝经。在引导药力进入肝脏方面最为迅速有效。能消除风热，杀灭寄生虫，消散瘰疬（颈部淋巴结结核），治疗惊痫（小儿惊风抽搐）。能镇心安神，明目，利水消肿。与朱砂配伍，可治疗风秘（因风邪引起的便秘）。与甘草配伍，外敷可治疗疮疡。佐使君子同用，可治疗脾疳（小儿脾胃虚弱导致的疳积）。加入盐汤中漱口，可治疗牙齿疾病。（也可以将黄柏与甘草研成粉末外敷。）脾胃虚寒导致腹泻者禁用。
【芦荟】
味咸、苦，性大寒。能泻热祛风，治疗齿衄（牙龈出血），消散瘰疬，去除结核（皮下结节），清利咽喉，止热痛。与黄丹配伍，撒敷可治疗走马疳（一种严重的口腔坏疽病）。佐地骨皮同用，漱口可治疗牙宣露（牙龈萎缩、牙根暴露）。治疗喉痹，磨水涂抹患处，引出痰涎即可痊愈。服用过多会引起呕吐。

【川黄柏补充论述】
畏伏硫黄，恶干漆。
味苦，性寒。入足少阴肾经血分。能泻下焦潜伏之火，清除脏腑深层的湿气；对于小便淋漓不畅或闭塞、水样腹泻、血痢，若由湿热引起者，适宜用此药治疗。与肉桂配伍，可治疗咽痛。（肉桂是命门的钥匙，依赖它来开启气机。）与知母配伍，可降肺火。佐苍术同用，可治疗湿痿（因湿邪导致的肢体痿软无力）。（黄柏可直接入药发挥作用。）使细辛同用，可泻膀胱之火。（细辛用量二至三分。）
治疗上部疾病，用酒炮制；治疗中部疾病，用蜜炙；治疗下部疾病，用盐水炮制。治疗崩漏和带下病，炒炭使用；外用治疮疡，用乳汁调敷。脾胃虚寒腹泻者，以及尺脉细弱者，这两种情况禁用。
川黄柏补水，是因为它能清除从下焦向上泛溢的阴火，火清除后，水液得以坚固凝聚，看似未补而实则已补。因为阴中的邪火，本来就不是命门的真火，不妨用苦寒的药物来清除它。如果是肾中的真水不足，导致水中的真火虚浮于上，应该用地黄等药物来滋养，水充足则火自然归藏。如果误投知母、黄柏，会使水液更加干燥，火势更加炎上，反而形成孤阳飞越的局面，无法救治。
又说：命门之火，安守其位即为生生不息的少火，离开其位就成为灼烧阴液、消耗元气的壮火，这是令人畏惧的火势。如果不是急迫需要清除，川黄柏、牡丹皮是必需的。然而，如果是少火偏离了位置，失去了水的源头，使用川黄柏的苦燥之性，不如牡丹皮的辛润之性，这样才不会损伤真阴。
[Chuan Huangbai (Phellodendri Cortex)]
Bitter, cold. Enters the Foot Jueyin Liver Meridian. It is most effective in guiding medicinal properties into the Liver. It dispels wind-heat, kills three types of parasites, dissipates Luoli (scrofula), and treats Jingxian (convulsions). It calms the Heart and brightens the eyes, promotes urination to reduce edema. When combined with Zhusha (Cinnabar), it treats Fengmi (constipation due to wind). Paired with Gancao (Licorice Root), applied externally for sores. Assisted by Shijunzi (Quisqualis Fruit), it treats Pi Ganic (spleen-type malnutrition). Added to salt water for rinsing teeth. (It can also be ground with Gancao and applied externally.) Contraindicated in cases of diarrhea due to Spleen-Stomach deficiency-cold.
[Lu Hui (Aloe)]
Salty, bitter, very cold. Clears heat and expels wind, treats Chi Ni (gum bleeding), dissipates Luoli, removes tubercles, clears the throat, and stops painful heat. Combined with Huangdan (Red Lead Oxide), sprinkled on Zouma Gan (gangrenous stomatitis). Assisted by Digupi (Lycii Cortex), used for gargling to treat Ya Xuanlu (receding gums exposing tooth roots). For treating Hou Bi (throat obstruction), grind into water and apply to sweep away phlegm; recovery follows. Excessive consumption causes vomiting.

[Supplementary Discussion on Chuan Huangbai]
Feared by Fuliuhuang (Sulfur fixed with mercury), adverse to Gan Qixi (Dry Lacquer).
Bitter, cold. Enters the Blood aspect of the Foot Shaoyin Kidney Meridian. Purges latent fire in the Lower Jiao, eliminates dampness in the deepest Yin organs. For Lin Mi (difficult or obstructed urination), watery diarrhea, and bloody dysentery caused by damp-heat, this herb is suitable. Combined with Rougui (Cinnamon Bark), it treats sore throat. (Rougui is the key to the Mingmen [Gate of Life], relying on it to open the Qi mechanism.) Paired with Zhimu (Anemarrhenae Rhizoma), it descends Lung fire. Assisted by Cangzhu (Atractylodis Rhizoma), it treats Shi Wei (flaccidity due to dampness). (Huangbai enters directly.) With Xixin (Asari Radix et Rhizoma), it purges Bladder fire. (Xixin dosage: 2-3 fen.)
For treating upper body conditions, process with wine. For middle body conditions, honey-fry. For lower body conditions, process with salt water. To stop Beng Dai (metrorrhagia and leukorrhea), char to carbon. For external application on sores, mix with milk. Contraindicated in cases of Spleen-Stomach deficiency diarrhea and when the Chi pulse is fine and weak.
Chuan Huangbai "nourishes Water" because it clears Yin Fire that overflows upward from the Lower Jiao. Once the fire is cleared, Water becomes firm and consolidated; thus, it nourishes without being explicitly tonifying. This is because the evil fire within the Yin is not the True Fire of the Mingmen, so it is acceptable to eliminate it with bitter-cold herbs. However, if the True Water of the Kidney is insufficient, causing the True Fire within the Water to float upward, one should use Dihuang (Rehmanniae Radix) to nourish it. When Water is sufficient, Fire naturally returns to its storage. If Zhimu and Huangbai are mistakenly administered, Water becomes drier and Fire more blazing, resulting in a state of solitary Yang flying away, which is incurable.
It is also said: The Fire of the Mingmen, when staying in its position, is the Sheng Sheng Zhi Shao Huo (vitalizing mild fire); when leaving its position, it becomes Zhuang Huo (excessive fire) that scorches Yin and consumes Qi, which is feared. If urgent removal is not required, Chuan Huangbai and Mudanpi (Moutan Cortex) are necessary. However, if Shao Huo leaves its position due to loss of Water source, using the bitter-drying nature of Chuan Huangbai is inferior to the acrid-moistening nature of Mudanpi, as the latter does not damage True Yin.
