望江青，又名还精草、玉星草、银脚鹭鸶、血见愁。它在谷雨节气后萌发新苗，生长于水泽旁边或湖岸之上。其茎呈方形且中空，叶片狭长而尖端锐利，边缘有锯齿，在茎节上对生。小满节气后抽出花茎，开花形成穗状，花朵细小呈紫色，层层向上排列。到了寒露节气时植株枯萎，根部有很多须根，茎节部分呈方形且白色，非常长，也是空心的，其中根部药效尤为奇妙。
王圣俞说：银脚鹭鸶的叶子像胡麻但较小，直立的茎大约一尺多长，叶子对生，根部极像水芹，味道甘甜且汁液丰富。采摘后用蜂蜜拌匀蒸熟食用，能治疗肺虚导致的失音，长期服用最有益于人。西湖周边的山上都有这种植物，根据上述描述，这似乎是另一种植物。因为望江青的根部是白色但不长，如果根部很长，那就是银脚鹭鸶了。这里将两者并存，以等待进一步考证。
《李氏草秘》记载：望江青，俗称天芝麻。因为它的叶子像芝麻叶。茎秆方形，叶子对生，到春节期间开红紫色的花，味道凉苦。《百草镜》记载：性寒，味微苦，归肺经。吐血患者服用它，能生精恢复体力，清除湿热，去除眼部的星障（角膜云翳），治疗肺痈（肺部化脓性疾病）、劳力损伤、脱力黄病（因过度劳累导致的萎黄病）。与金器一起煎煮服用，可治愈惊风。
治疗跌打损伤，具有极强的活血作用，捣烂取汁冲酒服用，药渣敷在受伤处。有一人脚踝扭伤，疼痛得无法抬起。当时没有嫩苗，便寻找其根部，捣汁加入煎剂中，服用三次后痊愈。与牛膝、芍药、当归、独活、玉钗草、活血丹、七叶草、五爪龙、放棒行、金雀脑、覆丝藤、[缺失字]草等药材混合，均匀捣汁，加酒服用，即使损伤严重濒临死亡，只要药液咽下即可救活。同时治疗各种溃烂疼痛、疮癣，治疗吐血也有效。
眼中去除星翳障：《百草镜》记载：望江青一两，羊肝一副，同豆腐一起煮食。
吐血：白蜜二两，隔水炖熟，望江青一两，煎取汁液冲入蜂蜜中服用。无论是旧疾还是新发，一切血症，服用两次即可见效，效果奇妙。
乳痈（急性乳腺炎）和乳核（乳房肿块）：《秋泉家秘祖传天下第一奇方》：专门治疗乳痈和乳核肿大坚硬者，服用后即刻内部消散。使用九龙川（即龙见怕）一两，细叶冬青（即山黄杨）五钱，龙爪紫金鞭（即马鞭草，又名龙爪草）一两，金剪刀三钱，九节金丝草（即望江青）五钱，遍地金龙草（即地五爪）三钱。用无灰酒两碗，加入香橼叶或桔叶十余片，煎至半钟，空腹时酌情服用两三次，药渣再煎服用。
我的表亲张石港，生平常服望江青，每天用干品三钱，配北枣六枚一同煎煮食用，如此坚持三年，身体轻盈，脚步矫健，终身无病，其功效不亚于人参。
Wangjiangqing (Aconitum coreanum or similar species, context-dependent), also known as Huanjingcao (Jing-Returning Grass), Yuxingcao (Jade-Star Grass), Yinjiao Lusi (Silver-Footed Egret), and Xuejianchou (Blood-Sorrow). It sprouts after the Guyu solar term, growing beside water marshes or lake shores. Its stem is square-shaped and hollow; leaves are narrow, long, and pointed, with serrated edges, arranged oppositely on nodes. After the Xiaoman solar term, it sends up flowering stalks bearing spike-like inflorescences with small, layered purple flowers. With the Hanlu solar term, the plant withers; the root system has many fibrous roots, and the internodes are square, white, very long, and transparent/hollow. The root is particularly efficacious.
Wang Shengyu stated: The leaves of Yinjiao Lusi resemble Sesamum indicum (Huma) but are smaller; the erect stems are about one chi in length; leaves are opposite; the root closely resembles Apium graveolens var. dulce (Shuiqin/Water Celery), tastes sweet, and is rich in juice. It can be harvested, mixed with honey, steamed, and eaten to treat hoarseness due to Lung deficiency (Fei Xu Shi Yin); long-term consumption is most beneficial. It grows in the hills around West Lake. Based on this description, it seems to be a different species. Wangjiangqing has white but short roots; if the root is long, it is Yinjiao Lusi. Both are recorded here pending further verification.
*Li Shi Cao Mi* records: Wangjiangqing is commonly called Tianzhima (Heavenly Sesame) because its leaves resemble sesame leaves. The stem is square, leaves are opposite, and it blooms with red-purple flowers during the Spring Festival; the taste is cool and bitter. *Baicao Jing* records: It is cold in nature and slightly bitter in taste, enters the Lung Meridian (Fei Jing). It is taken for hemoptysis (Tu Xue), generates essence and restores strength, removes damp-heat, clears corneal nebulae (Xingzhang), treats lung abscess (Fei Yong), labor injury, exhaustion-induced jaundice (Tuoli Huang). When decocted with gold vessels and taken orally, it cures convulsions (Jing Feng).
For treating contusions and bruises, it strongly invigorates blood (Huoxue). Crushed juice is taken with wine, and the dregs are applied to the injured area. One person suffered an ankle sprain with pain preventing movement. Without fresh shoots, the root was sought, crushed for juice, added to a decoction, and taken three times, resulting in recovery. Combined with Achyranthes bidentata (Niuxi), Paeonia lactiflora (Shaoyao), Angelica sinensis (Danggui), Angelica pubescens (Duhuo), Yuanchaocao, Huoxuedan, Qiyecao, Wuzhao Long, Fangbangxing, Jinqiaonao, Fusiteng, [missing character]cao, etc., uniformly crushed for juice, taken with wine, it can save patients dying from severe injuries, provided the medicine reaches the throat. It also treats various ulcerative sores, tinea, and is effective for hemoptysis.
To remove corneal nebulae from the eyes: *Baicao Jing* records: Wangjiangqing 1 liang, sheep liver 1 piece, cooked together with tofu and eaten.
Hemoptysis: White honey 2 liang, steamed over boiling water until ripe; Wangjiangqing 1 liang, decocted for juice, mixed with honey and taken. Whether old or new onset, for all blood disorders, two doses bring remarkable results.
Mastitis (Ruyong) and breast nodules (Ruhe): *Qiuquan Jiemi Zuchuan Tianxia Diyi Qifang*: Specifically treats large, swollen, and hard mastitis and breast nodules, causing internal resolution upon ingestion. Use Jiulongchuan (Longjianpa) 1 liang, Xiye Dongqing (Shanhuangyang) 5 qian, Longzhua Zijinbian (Biancahu/Ma Biancao, also known as Longzhua Cao) 1 liang, Jinjiandao 3 qian, Jujie Jinsicao (Wangjiangqing) 5 qian, Biandi Jinlongcao (Diwuzhao) 3 qian. Decoct with 2 bowls of pure rice wine (Wuhui Jiu), add more than ten slices of Citrus medica (Xiangyuan) leaves or Citrus reticulata (Ju) leaves, boil down to half a zhong. Take 2-3 times according to appetite when hungry, and decoct the dregs again for consumption.
To interrupt malaria (Jue Nüe): Dry Wangjiangqing 5 qian, decocted in wine and taken.
My cousin Zhang Shigang regularly consumed Wangjiangqing in his life, using 3 qian of dried herb daily, decocted with six northern dates (Beizao). He persisted for three years, becoming light-bodied and agile-footed, free from illness for life. Its efficacy is not inferior to Ginseng (Renshen).
