《百草镜》记载：俗名叫铁边箕，山野各处都有生长。叶子像天门冬的叶子，又像土茯苓的叶子，只是稍微狭小一些。它是藤本植物，有的攀附在石阶上、树上或竹林里也有生长，并不是海金沙；它的根是黑色的，两旁有细刺像簸箕的边缘一样，因此得名，入药使用根部。赵学敏按语：现在民间常用它治疗各种喉部病症。“金锁银开”其实是天荞麦的根，形状像累积的丸子，粘结成块。产在山上的，表皮黄色；长在污泥中的，表皮黑色，这与《百草镜》所说的情况各不相同，或许是名字相同但实物不同呢？
李氏《草秘》记载：天荞麦又名金锁银开，形状像荞麦，能治疗乳痈和风毒，加入各种散毒药中内服。取根二分，生姜一分，水煎后服用，即可痊愈。治疗因败血导致的久病不愈，以及清洗痔疮出血，效果都很好。
李氏《草秘》又说：小青草的藤蔓上有倒钩刺，细得像稻芒，开粉红色的花，结兰子形状的果实，叶子像荞麦叶，又名野荞麦，是煎洗痔漏的圣药。治疗白浊症用根部，捣汁冲酒服用。
治疗喉中风火：孙玉庭说：这种植物的根专门治疗喉闭，所以得到这个名称。对于喉风、喉毒，用醋磨碎后漱口咽喉，涎痰去除后喉闭即解。对于痰核、瘰疬，无论是何种结核初起的情况，都适用。梁湖陈府秘方：使用金锁银开（必须是新鲜的），将其捣汁冲酒服用；其茎、叶用白水煮烂，和米粉做成饼饵食用，不过两三次就能立即消除。如果是已经溃烂的疮口，用梁上乌龙尾揉去粗屑，塞入疮口中，外面贴膏药，同时服用根汁，吃饼饵五到六次，自然会结痂痊愈。
汪连仕《采药书》记载：金须钭，俗呼金锁银开，其苗柔韧且坚性不断，现在的名字叫象毛，力量能软化坚硬之物化解痞块，配合米醋捣汁漱口，能解开缠喉风的束缚，即使是干枯的根也能透开锁喉之症。
*Bai Cao Jing* records: It is commonly known as "Iron-edged Winnowing Basket" (Tiebian Ji), found in mountains and fields everywhere. The leaves resemble those of *Asparagus cochinchinensis* (Tianmendong) or *Smilax glabra* (Tufuling), but are slightly narrower. It is a vine, growing on stone walls, trees, or in bamboo forests; it is not *Lygodium japonicum* (Haijinsha). Its root is black with fine thorns on both sides resembling the edge of a winnowing basket, hence the name. The root is used medicinally. Zhao Xuemin notes: Currently, it is commonly used to treat all kinds of throat conditions. "Jinsuo Yinkai" actually refers to the root of *Fagopyrum dibotrys* (Tianqiaomai), shaped like accumulated pills, clumped together. Those produced on mountains have yellow skin; those in muddy soil have black skin. This differs from what *Bai Cao Jing* describes; perhaps they share the same name but are different substances?
Li's *Caomi* records: Tianqiaomai is also named Jinsuo Yinkai. Its shape resembles buckwheat. It treats breast abscesses (Ruyong) and wind-toxins. When added to various dispersing and detoxifying powders, take 2 fen of the root and 1 fen of fresh ginger (*Zingiberis Rhizoma Recens*), decoct in water and take orally for cure. It is effective for chronic illnesses due to blood stasis and for washing hemorrhoidal bleeding.
Li's *Caomi* further states: The vines of Xiaoqingcao have backward-pointing prickles, fine as rice awns. It bears pink flowers and fruit resembling "Lanzi". The leaves look like buckwheat leaves. Also called wild buckwheat (Yeqiaomai), it is a sacred medicine for decocting and washing fistulas (Zhilou). For treating cloudy urine (Baizhuo), use the root, crush to extract juice, and mix with wine for oral administration.
Treating Wind-Fire in the Throat: Sun Yuting says: The root of this plant specifically treats throat closure (Houbi), which is how it got its name. For throat wind (Houfeng) and throat toxins, grind with vinegar and gargle/swallow to remove saliva and phlegm, thereby relieving throat closure. For phlegma nodules (Tanhé), scrofula (Luoli), and any type of early-stage tubercles, it is applicable. Secret Formula of Chen Mansion in Lianghu: Use fresh Jinsuo Yinkai, crush to extract juice, and mix with wine for oral administration. Boil the stems and leaves in plain water until soft, mix with rice flour to make cakes/biscuits, and eat them. Within two or three doses, the condition will resolve immediately. If the sore is ulcerated, use the tail of "Wulong on the Beam" (Liangshang Wulong), rub off coarse debris, insert into the wound, apply an external plaster externally, while simultaneously taking root juice and eating the cakes five to six times. The wound will naturally scab over and heal.
For washing fistulas and treating snake bites and "wood snake" toxicity, crush to extract juice and mix with wine for oral administration (from *Caomi*).
Wang Lianshi's *Caiyao Shu* records: Jin Xu Diao, commonly called Jinsuo Yinkai. Its seedlings are flexible yet tough and unbreakable. It is now known as Xiangmao. It has the power to soften hardness and dissipate masses (Pi). Mixed with rice vinegar and crushed to extract juice for gargling, it can unlock "Chanting Throat Wind" (Chanhou Feng). Even dried roots can penetrate and relieve throat-locking conditions.
