〔论述〕李时珍（濒湖）说：这两种水都取自蓝草和锻石，具有杀虫解毒的意义。然而蓝草的治疗作用，在于能够广泛生发阳气。至于粳米第二次淘洗的水，清澈且可用，因此得名。气味甘寒。能清热，缓解上焦烦渴，通利小便，凉血。

主治消渴症，效果显著。
主治胎衣不下，服用一盏，不要让病人知道。
凡是所有的补药和各种膏剂，适宜用这种火来煎煮。所有的仙药，不用桑木煎煮就不服用。桑树是箕星的精华，能辅助药力，祛除风寒痹痛等各种疼痛，长期服用终身不得风疾。（出自《抱朴子》）桑木火灸治疗痈疽发背不起发，瘀肉不腐烂，以及阴疮瘰疬流注等顽固疮疡，点燃火吹灭后，每天灸两次，未溃破时拔毒止痛，已溃破时补接阳气，去除腐肉促进新肌生长。火能畅达拔引郁结之毒，这是从治的方法。（出自朱丹溪）桑木能利关节，养津液，遇到火则拔引毒气，祛除风寒，所以能去腐生新。（出自李时珍）但不可用艾条直接点灼以免损伤肌肉。
栎炭火适宜炼制各种金石药物。炭火适宜烹煎焙炙各种丸散药物。将木头烧成炭，木头久了会腐烂，而炭埋入土中不腐烂，是因为木头有生发性，炭没有生发性。葬家用炭，能使虫蚁不进入，竹木之根自然回生，也是因为它没有生发性。（出自李时珍）治疗白虎风痛，日夜游走不定，百节如被啃咬者，取炭灰五升，蚯蚓屎一升，红花七捻，混合熬制，用醋拌和，用旧布包成两包，交替熨烫疼痛处，可获效。
Taste: pungent, bitter. Nature: cold. Clears heat. Resolves toxicity. Kills parasites. If leeches are accidentally swallowed and cause accumulation, leading to abdominal distension, pain, jaundice, emaciation, and sallow complexion, drinking this water will expel them, resulting in recovery.
For throat diseases and dysphagia (difficulty swallowing), taking one cup warm is effective.
[Discussion] Li Shizhen (Binhu) stated that both waters are derived from Indigofera plants and iron slag, sharing the meaning of killing parasites and resolving toxicity. However, the therapeutic action of Indigo water lies in its ability to widely generate and distribute yang qi. As for the second rinse water of japonica rice (Jingmi Xitishui, i.e., the water obtained from the second washing of rice), it is clear and usable, hence the name. Taste: sweet. Nature: cold. Clears heat. Relieves upper jiao irritability and thirst. Promotes urination. Cools blood.
Taste: sweet. Nature: cool. Tonifies qi. Stops irritability and thirst associated with cholera-like disorders. Resolves toxicity. For indigestion after eating duck meat, drinking one cup at once facilitates digestion.
Collect in a bottle, seal tightly, and bury in clean soil; the longer it ages, the better.
Mainly treats xiaoke (wasting-thirst syndrome). Highly effective.
Mainly treats retained placenta. Take one cup. The patient should not be aware of the treatment.
All tonifying medicines and various pastes are best decocted using this fire. All "immortal medicines" must be decocted with mulberry wood to be effective. Mulberry trees are the essence of the Ji Star, capable of assisting medicinal power, dispelling wind-cold bi-syndrome and various pains. Long-term consumption prevents wind diseases throughout life. (From *Baopuzi*) Mulberry wood fire moxibustion treats carbuncles and sores that fail to suppurate or discharge pus, necrotic flesh that does not rot, as well as yin sores, scrofula, and flowing abscesses (luoli liuzhu). Ignite the fire and blow it out, apply moxibustion twice daily. Before ulceration, it draws out toxins and relieves pain; after ulceration, it supplements yang qi, removes necrotic tissue, and generates new muscle. Fire promotes free flow and draws out pent-up toxins; this is a contrary treatment method. (From Zhu Danxi) Mulberry wood benefits joints and nourishes body fluids. When exposed to fire, it draws out toxic qi and dispels wind-cold, thus enabling the removal of necrotic tissue and generation of new tissue. (From Li Shizhen) However, direct application of mugwort should be avoided to prevent skin damage.
Oak charcoal fire is suitable for refining all kinds of mineral drugs. Charcoal fire is suitable for decocting, roasting, and frying various pills and powders. Wood burned into charcoal does not rot when buried in soil, whereas wood rots over time, because wood possesses a "generative nature" while charcoal lacks it. Funeral homes use charcoal to prevent insects and ants from entering, allowing bamboo and tree roots to regenerate naturally, also due to its lack of generative nature. (From Li Shizhen) For white tiger wind-pain (severe migratory joint pain), where pain moves day and night and feels like biting in all joints, take five sheng of charcoal ash, one sheng of earthworm excrement, and seven pinches of safflower. Mix and roast together, blend with vinegar, wrap in two pieces of old cloth, and alternately apply hot compresses to the painful areas until effective.
