味苦，性寒，无毒。原本生长在永阳的池塘沼泽及河海边。临汝人叫它牛荭草，河北信都人叫它水节，河内连纳黄叫它水棘，剑南、遂宁等郡叫它龙移草。蜀郡人采集它的花混合在面药中。淮南各郡尤其适宜生长，茎、叶肥大，名叫海精木，也叫鱼津草。各地都有。单用服用，可治疗膝痛等症。其方剂记载：水英，主治男子、女子无故出现双脚肿胀满溢，连带膝盖和小腿疼痛，屈伸困难且僵硬者，这种病名叫骨风（Bone Wind）。此病不宜针刺和艾灸，也不宜服药，只有单独煮此药浸泡患处，不到五天即可痊愈，多次使用神效验灵。该药春季采收苗和根。患有上述疾病的人，每天取五、六斤，用水一石，煮取三斗药液，趁热浸泡脚部，兼淋洗膝盖，日夜三到四次，频繁日用，以痊愈为度。如果肿胀严重，就在前方基础上：加生椒目三升，加水两大斗，根据前面的方法煮取汁液，用来淋洗疮肿，随着汤药消散。待肿胀消退后，即涂抹粉剂并避风，才是良法。忌食油腻、蒜、生冷食物。
Bitter, cold in nature, non-toxic. Originally grows in the ponds, marshes of Yongyang, and along riverbanks and seashores. People in Linyu call it Niuhongcao (Cow Red Plant), people in Xindu, Hebei call it Shuijie (Water Joint), people in Liannehuang, Henei call it Shuiji (Water Thorn), and people in Jinnan, Suining and other commanderies call it Longyicao (Dragon Moving Grass). People in Shujun collect its flowers to mix into facial cosmetics. It is particularly suitable for growing in various commanderies of Huainan, with thick stems and large leaves, named Haijingmu (Sea Essence Wood) or Yujincao (Fish Saliva Grass). It is found everywhere. Taken alone, it treats knee pain and other conditions. The prescription states: Shuiying (Hydrocotyle chinensis) treats men and women who inexplicably suffer from swelling and fullness in both feet, extending to pain in the knees and shins, with difficulty in flexion and extension and stiffness; this condition is named Gufeng (Bone Wind). This disease is not suitable for acupuncture and moxibustion, nor for taking herbal medicines; only by decocting this herb alone to soak the affected area can one recover in less than five days. Frequent use proves miraculous. The herb should be harvested in spring, collecting both shoots and roots. Patients suffering from the aforementioned illness should take five to six jin daily, decocted in one dan of water until three dou of liquid remain. Soak the feet while hot, and pour over the knees, three to four times day and night, using it frequently until recovery. If the swelling is severe, add three sheng of fresh Sichuan pepper seeds to the previous prescription, add two large dou of water, and decoct according to the previous method. Use the liquid to wash the sores and swelling, allowing them to dissipate with the decoction. After the swelling subsides, apply powder and avoid wind, which is the best practice. Avoid greasy food, garlic, and raw/cold foods.
