曾氏说：肝在五行中属木，其变动应验为风象。患病时主要表现为惊骇不安。各种热邪引动肝风，风盛则生痰，痰阻则引发抽搐。小儿患惊风时，手足抽动掣动，应当听任其自行安定，然后再进行治疗，以免产生其他病变。如果父母见病势可怕，从而强行按压束缚患儿，哪里知道筋脉是肝的外合组织呢？发病时如果按压束缚其手足，就会导致筋脉不能舒展伸张，致使经络被风邪闭塞，最终导致惊瘫、鹤膝风，变成废人。凡是小儿心悸不定，以及全身肿痛，或者手足不能随意运动，这是惊瘫的证候。如果治疗稍晚，到了臂腕、膝胫骨节之间，流注凝结成顽固的硬块，或者膝盖肿大而小腿肌肉消瘦，胫骨显露，像鹤膝的形状；或者成为痈疽疖肿，这叫做鹤膝风的证候。这些情况都宜先用发汗法，使腠理开通，那么风热就可以清除，湿气也能随之而去。使用百解散配合五苓散料，加倍加入麻黄，加生姜、葱白煎服，以微微出汗为度。接着使用防己汤、独活汤加入桑寄生，或者黑虎丹制成小丸，间隔服用，使风不生而痰不作，就容易痊愈。如果是痈疽疖肿疼痛严重的，用黑牵牛（一半生用一半炒熟）研末，用无灰酒调服五苓散，以除去流注的寒湿，那么肿毒自然消除。如果邪气入腑导致闭塞不通，这是风热内蕴，表现为右腮红紧，以及右手寸关尺三部脉浮而滑实，适宜用五和汤或当归散。其加减变化尤其在于临机应变，如果拘泥于一方，就不是良医了。前症更宜间隔服用排风汤。
薛己说：鹤膝风，其腿部逐渐变细，其膝盖却越来越粗，形状像鹤的膝盖，因此得名。这是因为肾经不足，外邪乘虚而入。初起时膝盖内部作痛，外部颜色不变，伸展屈曲艰难。如果在一两个月间，肿胀色赤并化脓的，可以治愈；肿胀坚硬色白且不化脓的，难治。初起以大防风汤为主方，辅以益气养荣汤，这才是正确的治疗方法。
娄全善说：肝风引起的摇头，是因为肝血旺盛，外有风热乘袭，所以相互引动而摇晃不定。
王肯堂说：我还记得年轻时听朋友孙彭山说，曾经看见一个小孩患惊搐，请医生治疗，各种症状都退去了，只有头摇不止。后来一位老医生，在常服的药物中加入紫河车草（即重楼），立刻痊愈。考证这种草药，《神农本草经》名为蚤休，《唐本草》名为金线重楼，钱乙的方书中名为白甘遂。主治惊痫、摇头弄舌，这是《本经》正文记载的功效。古人说遵循经典原文治病多有效验，确实不假。
Zeng said: The Liver belongs to Wood in the Five Elements, and its movement corresponds to Wind. When diseased, it primarily manifests as fright and alarm. Various heat pathogens draw out Liver Wind; when Wind is excessive, it generates Phlegm, and Phlegm obstruction triggers convulsions. During an infantile wind-stroke (Jing Feng) episode, when the limbs twitch and jerk, one should allow them to settle naturally before administering treatment, to avoid inducing other complications. If parents, fearing the severity of the illness, forcibly restrain the child's limbs, they fail to realize that sinews are the external correspondence of the Liver. Restraint during onset prevents sinews from relaxing and extending, causing meridians to be blocked by Wind pathogenic factors, ultimately resulting in wind-stroke paralysis or Crissum Knee (He Xi), rendering the patient disabled. Whenever an infant exhibits irregular palpitations, generalized swelling and pain, or inability to move limbs voluntarily, this indicates a wind-stroke paralysis syndrome. If treatment is delayed until phlegm-dampness flows into the joints of arms, wrists, knees, and shins, forming stubborn nodules, or if the knees enlarge while calf muscles atrophy exposing the tibia resembling a crane's knee, or if carbuncles and sores appear, this is termed the Crissum Knee syndrome. For these conditions, diaphoresis (sweating method) should be employed first to open the interstices (Cou Li), thereby clearing Wind-Heat and eliminating Dampness. Use Baijie San combined with Wuling San ingredients, doubling the dosage of Ephedrae Herba (Mahuang), decocted with Zingiberis Rhizoma Recens (Shengjiang) and Allii Fistulosi (Congbai), aiming for a slight sweat. Subsequently, use Fangji Tang or Duohuo Tang added with Sangjisheng, or Heihu Dan prepared as small pills taken intermittently, to prevent Wind generation and Phlegm formation, facilitating recovery. For severe pain from carbuncles or sores, use half raw and half stir-fried Semen Koelreuteriae (Qian Niu Zi) ground into powder, administered with Wuling San mixed in non-grain alcohol (Wu Hui Jiu) to eliminate cold-dampness flowing through meridians, causing the swelling and toxicity to subside spontaneously. If pathogens enter the Fu organs causing blockage, indicating internal accumulation of Wind-Heat, characterized by redness and tightness on the right cheek, and floating, slippery, and excess pulse at all three positions (Cun, Guan, Chi) on the right hand, Wuhe Tang or Danggui San is appropriate. Modifications must be adapted to clinical circumstances; adhering rigidly to a single prescription is not the way of a good physician. For previous symptoms, Paifeng Tang should also be taken intermittently.
Xue Ji stated: Crissum Knee (He Xi Feng) is named so because the legs gradually become thin while the knees become increasingly swollen, resembling a crane's knee. This arises from insufficiency of the Kidney Meridian, allowing external pathogens to invade. Initially, there is pain inside the knee without external color change, and difficulty in extension and flexion. If within one or two months the swelling becomes red and suppurates, it is treatable; if it remains hard, white, and does not suppurate, it is difficult to treat. At the onset, Da Fangfeng Tang should be used as the principal formula, assisted by Yiqi Yangying Tang, which constitutes the correct treatment.
Lou Quanshan stated: Head shaking caused by Liver Wind occurs due to abundant Liver Blood combined with external Wind-Heat invasion, leading to mutual agitation and unstable trembling.
Weng Kentang recalled hearing from his friend Sun Pengshan in his youth about a child suffering from convulsions. After medical treatment, all symptoms subsided except for persistent head shaking. An old physician then added Paris Polyphylla Rhizome (Chong Lou/Ziheche Cao) to the usual medication, resulting in immediate recovery. According to records, this herb is known as Zao Xiu in Shennong Bencao Jing, Jin Xian Chong Lou in Tang Bencao, and Bai Gansui in Qian Yi's formulas. It treats fright, epilepsy, head shaking, and tongue protrusion, as recorded in the main text of the Classic. The ancients stated that following the original texts for treatment yields many effective results, which is indeed true.
