宣，具有祛除风热、定惊的功效。
味甘、微苦，性寒。能清除心经之热，平抑肝风，舒缓筋脉以消除眩晕，降气宽中。主治成年人头晕目眩，小儿惊哭抽搐。
（筋脉紧急收缩称为“螈”，筋脉松弛舒展称为“”，筋脉伸缩不止称为“螈”，现在称之为搐搦。）还可治疗客忤胎风，发斑疹。主要治疗肝风和相火引起的疾病。风静火息，则各种症状自然平息。（相火散布于胆、三焦、心包。）祛肝风而不燥烈，可谓中和之品，因此儿科医生珍视它。但药性稍寒，无实火者不要服用。其刺类似钓钩，因此得名。藤细且多钩的质量好。（去掉梗，纯用嫩钩，药效提高十倍。）久煎则效力减弱。（等其它药物煎好后，再放入钩藤，煮一两个沸次即可取出，效果很好。《圣惠方》治疗突然患癫痫，用钩藤、炙甘草各二钱，水煎服，有效。）
杀虫消积。
味甘，性温。能杀虫消积。治疗五疳便浊，泻痢疮癣，是治疗小儿各种疾病的要药。（《本草经疏》说：五疳便浊，泻痢腹中有虫，都是由于脾胃虚弱，导致乳停食滞，湿热瘀塞而成。脾胃健运则积滞消除，湿热消散，水道通畅，而驱虫的药，大多是苦辛味，唯独使君子、榧子，味甘而能杀虫。每月上旬，虫头向上；中旬虫头横卧；下旬虫头向下。《道藏》说：初一至初五，虫头向上。凡是有虫病的人，在每月上旬空腹吃几枚，虫子都会死掉排出。按地黄、胡麻，也都是甘味而能杀虫。）没有虫积的人不要吃。出产于闽蜀地区。果实五瓣有棱，里面的仁像榧子。也可以烤熟食用。时间久了油色变黑，不可使用。忌喝热茶，否则会引起腹泻。
一名旋花。补阴，续接筋骨。
味甘、辛，性温。补益劳损，益精气，续接筋骨。（用根捣汁，滴在受伤处，药渣敷在上面，每天换三次，半个月断掉的筋就能接续。）就是鼓子花。
Xuan (Gouteng), dispels wind-heat, calms fright.
Sweet, slightly bitter, cold in nature. Clears heart-heat, pacifies liver-wind, relaxes sinews to eliminate dizziness, descends qi and expands the middle jiao. Treats adults with vertigo and visual dizziness, and children with convulsive crying and spasms.
(Tight contraction of sinews is called "yuan", relaxation and extension of sinews is called "xi", continuous contraction and extension is called "yuan", now referred to as twitching or clonus.) Also treats external shock and fetal wind, macules and rashes. Primarily treats diseases caused by liver-wind and ministerial fire. When wind is still and fire subsides, all symptoms naturally resolve. (Ministerial fire circulates through the gallbladder, sanjiao, and pericardium.) Dispels liver-wind without causing dryness, thus achieving a balanced nature. Therefore, it is cherished in pediatrics. However, its nature is slightly cold; those without excess heat should not take it. Its thorns resemble fishing hooks, hence the name. Vines that are thin and have many hooks are of good quality. (Remove the stems, use only tender hooks, and the efficacy increases tenfold.) Long decoction reduces potency. (Wait until other herbs are decocted, then add Gouteng, boil for one or two boils, and remove; this yields good results. *Shenghui Fang* treats sudden epilepsy with Gouteng and Zhi Gancao each 2 qian, decocted in water and taken orally, effective.)
Kills parasites and eliminates accumulation.
Sweet, warm in nature. Kills parasites and eliminates accumulation. Treats five types of childhood malnutrition (wuzheng) with turbid urine, dysentery, sores, and tinea; it is an essential medicine for various pediatric diseases. (*Bencao Jingshu* states: Five types of wuzheng with turbid urine, dysentery, and abdominal worms are all caused by spleen and stomach weakness, leading to stagnation of milk and food, and obstruction by damp-heat. When the spleen and stomach are healthy, accumulations dissipate, damp-heat clears, and water passages flow freely. Most antiparasitic herbs are bitter and acrid; only Shijunzi and Feizi are sweet and kill parasites. In the first half of the lunar month, worm heads point upward; in the middle half, they lie horizontally; in the last half, they point downward. *Daozang* states: From the 1st to the 5th day, worm heads point upward. For those with parasitic diseases, eating a few fruits on an empty stomach during the first half of the month will cause the worms to die and be expelled. Note: Dihuang and Huma are also sweet and can kill parasites.) Those without parasite accumulation should not eat it. Produced in Min and Shu regions. The fruit has five petals with ridges, and the kernel inside resembles that of Feizi. It can also be roasted and eaten. If kept too long, the oil turns black and it becomes unusable. Avoid drinking hot tea after consumption, as it may cause diarrhea.
Also known as Xuanhua. Nourishes yin, reconnects sinews and bones.
Sweet, acrid, warm in nature. Tonifies labor damage, benefits essence and qi, reconnects sinews and bones. (Crush the root to extract juice, apply drops to the injured area, and cover with the residue; change three times a day, and broken sinews will reconnect within half a month.) This is the flower of Convolvulus arvensis (Bells-vine).
