性味甘平，轻扬上行，补中而举阳气下陷，宜煎补中升阳
有毒坏物，人饮之，多生脾胃疾。小满节前后淫雨，并为咸雨，其毒尤甚。
性甚消伐，有毒霉物，惟可洗疮疥灭痕。澄清入酱亦易熟。芒种后逢壬为入梅，小暑
逢壬为出梅，此时湿热熏蒸，人受其气则生病。物受其气则生霉。
性味清烈，解毒杀虫。宜制造疟、痢、疮、疡诸丹、丸、煎，辟祟药更效。
即五月五日午时雨，急伐竹竿沥取为神水。性味甘寒，清热化痰，定惊安神。和獭肝
丸，治心腹积，及杀劳虫及诸虫病。
性味甘寒，清热润燥，宜煎整肃肺气之药。
有毒，坏禾稻，人饮亦致多疾；与小满节内雨相近，性稍清肃耳。
立冬后十日为入液，至小雪为出液。液雨杀虫消积，宜煎虫痛疳积药。
气禀肃杀，功专泻热，阳气有余者，宜此煎药。
即方诸水。功专益阴退热，明目安神，除烦止渴，宜煎虚劳烦热之药。
甘平止渴，润肺解暑。百花上露∶令人明目，好颜色。
甘冷解酒热。和蚌粉，敷暑月痱疮。
