宜造疟痢、疮疡、金疮、百虫、蛊毒诸丹丸。用此水煎杀祟药，其效尤神。
消积清热。
甘寒。治心腹积聚及虫病。和獭肝为丸服。又饮之。清热化痰。定惊安神。（金门记云∶

月五日、午时有雨、急伐竹竿中、必有神水、沥取为药。以上三月水、大抵能助湿热、不
宜贮之。）
润肺。
宜煎整肃肺气之药。（湿热渐退、得秋金清肃下行之气、可多贮之。）
有毒，坏禾稻。（谚云∶寒露雨、偷稻鬼。）人饮之。多致疾。与小满水同。
杀虫消积。
宜煎杀虫消积之药。（立冬后十日为入液、至小雪为出液、得雨谓之液雨、亦曰药雨、
百虫
饮此皆伏蛰、至来春雷鸣起蛰、乃出也。）
泻热。
宜浸造滋补五脏及痰火、积聚、虫毒诸丹丸。并煮酿药酒。与雪水同功。（时珍以贮水

一名方诸水。补阴。

解毒杀虫。
适宜制作治疗疟疾、痢疾、疮疡、金创（金属利器造成的创伤）、百虫咬伤、蛊毒等各种丹丸药物。用这种水煎煮驱邪杀祟的药物，其疗效尤为神奇。
消积清热。
味甘性寒。治疗心腹部的积聚肿块以及寄生虫病。与獭肝混合制成丸剂服用。也可以直接饮用。具有清热化痰、定惊安神的作用。（《金门记》记载：五月五日午时如果有雨，急忙砍伐竹竿中间部分，必定会有神水流出，收集起来作为药物使用。以上提到的三月雨水，大抵会助长湿热之气，不宜储存。）
润肺。
适宜煎煮调理肺气肃降的药物。（随着湿热逐渐消退，得到秋季金气清肃下行的气候特点，可以大量储存这种水。）
有毒，会损害禾稻。（谚语说：寒露节气的雨水，是偷稻子的鬼怪带来的。）人如果饮用它，多会导致疾病。这与小满节气的雨水性质相同。
泻热。
感受天地肃杀之气。只有阳气有余的人，适宜用这种水煎药。
杀虫消积。
适宜煎煮杀虫消积的药物。（立冬后第十天为“入液”，到小雪节气为“出液”，此时下雨称为“液雨”，也称为“药雨”，百虫饮此雨水都会潜伏蛰伏，到来年春天雷声响起惊起蛰伏的虫子时，它们才会出来。）
泻热。
适宜浸泡制作滋补五脏以及治疗痰火、积聚、虫毒的各种丹丸。并用来煮酿药酒。其功效与雪水相同。（李时珍认为将水储存在二十四个节气中，是因为天地的气候相互感应，水的味道随之变迁，所以将节气水归入地水类；吴仪洛认为不对，毕竟天降雨水，感应天地气候更为准确，现在将其归入天水类，这样可以根据时令来选择使用。）
又名方诸水。补阴。
味甘性寒。主治明目。安定心神，止渴。去除小儿烦热。（李时珍说：明水，取其清明纯洁之意，表示极大的敬意。《周礼·司烜氏》用阳燧从太阳取明火，用方诸从月亮取明水，以供祭祀之用。魏伯阳《参同契》说：阳燧用来取火，不是太阳就不会产生光；方诸如果不是对着星月，怎么能取得水浆？《淮南子》说：方诸见到月亮，就会凝结出水珠。有的人认为方诸是一种石头，有的认为是大蚌，有的认为是五种石头炼成的，都不对。考证《考工记》说：铜和锡各占一半，叫做鉴燧的材料，火对应燧，水对应鉴。高堂隆说：阳燧又名阳符，从太阳取火；阴燧又名阴符，从月亮取水，都用金属制作，称为水火之镜，这个说法是正确的。《搜神记》说：金和锡的性质是一样的。在午月的丙午日午时铸造，称为阳燧；在子月的壬子日子时铸造，称为阴燧。）
Detoxifies and kills parasites.
Suitable for preparing various pills and electuaries to treat malaria, dysentery, sores and ulcers, metallic wounds (injuries caused by metal weapons), bites from various insects, and gu poison. Using this water to decoct herbs that expel evil spirits and kill malevolent entities yields particularly miraculous effects.
Eliminates accumulation and clears heat.
Sweet in taste and cold in nature. Treats accumulations and masses in the heart and abdomen, as well as parasitic diseases. Mix with liver of the otter (Lutra lutra) to form pills for oral administration. It can also be drunk directly. Clears heat, transforms phlegm, calms fright, and soothes the spirit. ("Jinmen Ji" records: On the fifth day of the fifth lunar month at noon, if it rains, one should hastily cut down the middle section of bamboo poles; there will surely be divine water flowing out, which can be collected for medicinal use. The rainwater mentioned above from the third lunar month generally tends to assist damp-heat and is not suitable for storage.)
Moistens the lungs.
Suitable for decocting herbs that regulate the descending function of Lung Qi. (As damp-heat gradually recedes and one receives the clear, descending energy of Autumn Metal, this water can be stored in large quantities.)
Toxic; damages crops. (A proverb says: Rain during Cold Dew is brought by rice-stealing ghosts.) Human consumption often leads to illness. Its nature is similar to that of rainwater during the Grain Buds solar term.
Drains heat.
Absorbs the killing energy of Heaven and Earth. Only those with excess Yang Qi are suitable for using this water to decoct medicines.
Kills parasites and eliminates accumulation.
Suitable for decocting herbs that kill parasites and eliminate accumulation. (Ten days after Start of Winter is "Ru Ye" [entering liquid state]; until Minor Snow is "Chu Ye" [exiting liquid state]. Rain falling during this period is called "Ye Yu" [Liquid Rain] or "Yao Yu" [Medicinal Rain]. All insects drink this rain and then hibernate. They emerge only when spring thunder awakens them.)
Drains heat.
Suitable for soaking and preparing pills and electuaries that tonify the five Zang organs and treat phlegm-fire, accumulations, and insect poisons. It is also used to brew medicinal wines. Its efficacy is the same as that of snow water. (Li Shizhen believed that storing water according to the twenty-four solar terms was due to the mutual resonance between heaven-earth climate and the changing flavor of water, thus classifying solar term water under terrestrial waters. Wu Yiluo disagreed, arguing that heavenly rainwater resonates more accurately with heaven-earth climate. Therefore, it is now classified under heavenly waters, allowing for selection based on seasonal timing.)
Also known as Fangzhu Water. Tonifies Yin.
Sweet in taste and cold in nature. Mainly treats brightening the eyes. Calms the Heart, relieves thirst, and removes vexatious heat in children. (Li Shizhen stated: Ming Shui [Bright Water] takes its name from clarity and purity, showing utmost reverence. In "Zhou Li - Si Xuan Shi", the Yang Sui [Bronze Mirror for Fire] extracts fire from the sun, and Fangzhu [Bronze Mirror for Water] extracts water from the moon, for sacrificial purposes. Wei Boyang's "Can Tong Qi" states: Yang Sui is used to extract fire; without the sun, there is no light. Fangzhu cannot produce water unless facing stars or the moon. "Huainanzi" states: When Fangzhu sees the moon, it condenses into water. Some believe Fangzhu is a stone, others say it is a large clam, or made from refined five stones; all are incorrect. Examining "Kaogong Ji": Copper and tin mixed equally constitute the material for Jian Sui. Fire corresponds to Sui, water corresponds to Jian. Gao Tanglong said: Yang Sui is also called Yang Fu, extracting fire from the sun; Yin Sui is also called Yin Fu, extracting water from the moon. Both are made of metal and called mirrors of water and fire. This theory is correct. "Soushen Ji" states: The nature of gold and tin is identical. Cast on Bingwu day of Wuyue (Fifth Month) at noon, it is called Yang Sui; cast on Renzi day of Ziyue (Eleventh Month) at midnight, it is called Yin Sui.)
