《医方集听》记载：这是治疗血证的圣药，又名牛泥茨、三珠草、天紫苏。三月生苗，形状像麻，叶上有细微的绒毛，取叶子咀嚼，味道像苦萝（一种野菜），久嚼后微带辛味。大叶旁有两片小叶，形状像杏叶。到了八九月，每片叶子上结出三粒果实，形状像粟米粒，其中一粒像菜籽，嫩时呈青色，老了变成黑色，取种子入药。用于治疗咳嗽伤肺。开细小的紫红色花，从五月开始，直到十月结束，到处都有生长。
治疗血症：《集验方》记载，取叶子同虎杖、龙芽草一起使用。治血崩：《集验方》记载，用黄麻叶连根捣烂，用酒煎煮并露天放置一夜，次日清晨服用。
汪连仕说：大麻子就是黄麻子，性热，能行血，医生将其与曼陀罗花（风茄）混合制成麻醉药使用。
丁未年，我在奉化做馆师，当地人在暑月都以此植物代替茶饮用，说它能消食健脾，性寒，解暑效果神奇。五月内，山村人通常割下晒干捆扎，挑到城市售卖，我用一百文钱买了一束，样子像干薄荷，但长大一倍多，茎上缀着白色珠子结成穗状。当地人说是：种子能降气消食，比枝叶功效更强。我偶然感到痞闷不适，便取一枝冲泡汤剂代茶饮，第二天，食欲异常旺盛，所说的确实不虚假。《三才藻异》记载：一名六月冷，即曲节草。性寒，所以得名。花像薄荷，叶像刘寄奴，名叫蛇蓝。
性味苦寒，也能厚肠胃，止痢疾、开胸膈，吃了让人胃口好。凡是伤寒、时疫（流行性传染病），取一株带种子的煎服，能起死回生。
按语：《本草纲目》中的曲节草：一名六月霜。李时珍（濒湖）所引用的《图经本草》记载：甘平无毒，治疗发背（背部痈疽）、消痈拔毒，同甘草研成末，米汁调服。而其他特殊疗效并未提及，现在予以补充。
*Yifang Jiting* records: This is a sacred medicine for treating blood disorders, also known as Niunici (Ox Mud Thorn), Sanzhucao (Three-Berry Grass), and Tianzisu (Heavenly Perilla). In the third lunar month, seedlings emerge resembling hemp; the leaves have fine hairs. Chewing the leaves yields a taste similar to *Kuoluo* (a bitter vegetable), becoming slightly pungent after prolonged chewing. The large leaf has two smaller lateral leaves resembling apricot leaves. By the eighth and ninth lunar months, each leaf bears three seeds, resembling millet grains, with one seed resembling a mustard seed. When tender, they are green; when mature, black. The seeds are used medicinally to treat coughs damaging the lungs. It produces small purple-red flowers from the fifth to the tenth lunar months and is found everywhere.
For blood disorders: *Jiyan Fang* (Collected Effective Prescriptions) prescribes using the leaves together with *Huzhang* (Polygonum cuspidatum Rhizome et Radix) and *Longyacao* (Agrimonia pilosa Herb). For metrorrhagia (uterine bleeding): *Jiyan Fang* prescribes crushing the Huangma Ye (Hemp Leaf) with roots, decocting in wine, exposing it overnight, and taking it early the next morning.
It treats qi disorders causing heart pain and abdominal pain, as well as dysentery and pi-jie (abdominal masses/obstruction).
Seeds: Treat coughs damaging the lungs.
Wang Lianshi states: Dama Zi (Cannabis Seed) is the same as Huangma Zi. It is hot in nature and promotes blood circulation; physicians combine it with Fengqie (Datura Metel Flower) to create anesthetic agents.
In the Dingwei year, I served as a tutor in Fenghua. Locals drank this plant as tea during the summer months, claiming it aids digestion and strengthens the spleen. Its nature is cold, and its heat-clearing effect is miraculous. In May, villagers typically cut, dry, and bundle it, carrying it to cities for sale. I purchased a bundle for 100 cash. It resembled dried mint but was twice as large, with white beads forming spikes on the stems. Locals stated that the seeds descend qi and aid digestion more effectively than the leaves/stems. Upon experiencing occasional chest fullness and discomfort, I took one branch, brewed it as tea, and by the next day, my appetite was exceptionally strong. Thus, their claims are not false. *Sancai Zao Yi* records: Also known as Liuyueleng (June Cold), which is Qujie Cao (Polygonum aviculare Herb). Its nature is cold, hence the name. The flowers resemble mint, and the leaves resemble Liu Jinu (Artemisia anomala Sledge), so it is named She Lan (Snake Blue).
For clearing summer-heat: It eliminates stagnation; it is excellent for children to drink as tea during summer.
Its flavor is bitter and cold; it also thickens the stomach and intestines, stops dysentery, opens the diaphragm, and improves appetite. For any case of Shanghan (Cold Damage) or Shi Yi (epidemic febrile diseases), decocting and ingesting one stem with seeds can revive the dying.
Note: In *Bencao Gangmu*, Qujie Cao is also known as Liuyueshuang (June Frost). Benhu (Li Shizhen) cited *Tujing Bencao*: Sweet, neutral, non-toxic; treats Fabei (back carbuncle), dissipates abscesses, extracts toxins. Mixed with Gancao (Licorice Root) into powder and taken with rice juice. However, other special efficacies were not mentioned; these are now supplemented.
