钩藤禀受春季生发之气而生长，因此味道甘甜、微苦，气性平和、微寒，无毒。它是手少阴心经和足厥阴肝经的重要药物。少阴经主火，厥阴经主风，风与火相互搏结，就会引发寒热交替、惊悸抽搐等病症。此药气味甘寒，直接作用于这两条经络，使风息火静，从而令肝心安宁，寒热惊痫等症状自然消除。
钩藤能舒缓筋脉、消除眩晕，降逆气、宽胸中痞闷，主治寒热惊痫、手足抽搐（瘛疭）、胎风及客忤（小儿突受惊吓或外邪侵袭所致之病）、口眼歪斜抽动。它入足厥阴肝经（主风）和手厥阴心包络（主火），既然能治疗风火燥热，那么抽搐拘挛的病症也会自愈。若再配合养血药物使用，更能显现其神奇功效。因其性微寒，儿科医生非常珍视它，但成人若无热证则不宜多用。
主治（结合痘疹病症参考）：主治因寒热引发的惊悸，驱散肝风而不燥烈，属于性质中和的药物。但久煎会使其药效减弱，应待其他药物煎好后，将钩藤投入沸水中煮一二分钟即取出，这样效果颇佳。去除梗部纯用嫩钩，功效增强十倍。
淡竹叶禀受阴气而生长，因此味道甘甜，性寒，无毒。它入足阳明胃经和手少阴心经。
淡竹叶能清除上逆之气引起的咳嗽气喘、胸中痰热导致的咳嗽，退除虚热，缓解烦躁失眠，治疗阳明经客热引起的口渴。它专门清凉心经，并清理肺胃，利尿消痰。其药性有行散而无固守之功，不能补益人体。孕妇忌服。竹竿刮去青色外皮，取向内黄色的部分称为竹茹，主治胃热引起的呃逆、噎膈呕吐、妊娠恶阻呕吐，使用效果显著。虽然竹茹与竹叶同出一源，但竹茹得土气较多，所以味道甘微寒，专门入足阳明胃经。
主治（结合痘疹病症参考）：清心除热，解烦止渴，治疗喘咳痰热、惊悸不语、胸中烦热，为通用良药。但不适宜在痘疹初起灌浆阶段使用，且竹子容易耗损正气，所以古人称笋为“刮肠篦”，宜暂用不宜久用。
蛀竹屑，即年代久远枯竹中的虫蛀碎屑。竹子的残余元气尚存，气味甘平无毒，甘味能解毒，平性兼有消散作用。竹性最凉，因此是腐蚀脓液、促进肌肉生长的神效药物。与象牙、真珠、白矾等药物配合，能消除漏管（窦道）。对于耳内流出臭脓的情况，可用蛀竹屑、胭脂胚子各等份，加少许麝香，研成细末，吹入耳中。若耳脓疼痛，是因水进入耳中引起，可用蛀竹屑一钱、轻粉一钱、麝香五分研末，先用棉签棒擦净耳道，送入药物，用棉花塞住固定。若有污物，让其流出，严重者三次必愈。对于湿毒疮，可用蛀竹屑与黄柏末等份，先用葱椒茶汤洗净患处并挑破，每日一次，有效。对于汤火烫伤，敷上蛀竹屑末也能痊愈。
Gouteng (Uncaria rhynchophylla) inherits the Qi of spring to grow; therefore, its taste is sweet and slightly bitter, its nature is neutral and slightly cold, and it is non-toxic. It is an essential herb for the Hand Shaoyin Heart Meridian and Foot Jueyin Liver Meridian. The Shaoyin governs Fire, and the Jueyin governs Wind. When Wind and Fire contend with each other, it results in alternating chills and fever, convulsions, and epilepsy. This herb's sweet and cold flavor directly targets these two meridians; when the wind subsides and fire extinguishes, the Liver and Heart become tranquil, and the symptoms of chills, fever, convulsions, and epilepsy are naturally eliminated.
Gouteng relaxes the sinews and eliminates dizziness, directs rebellious Qi downward and expands the middle jiao. It treats alternating chills and fever, convulsions, spasms of the hands and feet (chi zong), fetal wind, and sudden fright (ke wu), as well as twitching of the mouth and eyes. It enters the Foot Jueyin Liver Meridian (which governs Wind) and the Hand Juexin Pericardium Meridian (which governs Fire). Since it treats wind-fire dryness, diseases such as spasms and contractures heal themselves. When combined with blood-nourishing herbs, its miraculous efficacy becomes even more apparent. Due to its slightly cold nature, it is highly valued in pediatrics, but adults without heat syndromes should not use it in large doses.
Indications (Integrated with Smallpox/Rash Diseases): Treats convulsions triggered by chills and fever; expels Liver Wind without causing dryness. It is a harmonizing agent. However, prolonged decoction renders it ineffective. It should be added to the boiling decoction of other herbs for only one or two minutes before removing. Its efficacy is significantly enhanced if the stems are removed and only the tender hooks are used, increasing potency tenfold.
Dan Zhuye (Lophatheri Herba) inherits Yin Qi to grow; therefore, its taste is sweet, its nature is cold, and it is non-toxic. It enters the Foot Yangming Stomach Meridian and the Hand Shaoyin Heart Meridian.
Dan Zhuye clears upward-rebellious Qi causing cough and asthma, resolves phlegm-heat in the chest causing cough, reduces deficiency heat, relieves irritability and insomnia, and treats thirst caused by exogenous heat in the Yangming channel. It specifically cools the Heart Meridian and clears the Lungs and Stomach. It promotes urination and eliminates phlegm. Its action is dispersive without retaining, so it cannot tonify the body. Pregnant women should avoid it. The inner yellow bark scraped from the bamboo stem is called Zhuru (Bambusae Caulis in Taeniam). It treats hiccup due to Stomach Heat, dysphagia, vomiting, and morning sickness during pregnancy, showing miraculous effects. Although Zhuru and Dan Zhuye share the same source, Zhuru obtains more Earth Qi; thus, its taste is sweet and slightly cold, and it specifically enters the Foot Yangming Stomach Meridian.
Indications (Integrated with Smallpox/Rash Diseases): Cools the Heart and eliminates heat, resolves irritability and quenches thirst. It is generally used for cough with phlegm-heat, palpitations with inability to speak, and irritability in the chest. However, it is unsuitable during the initial eruption and pustule-filling stage of rashes. Furthermore, bamboo can damage Qi; hence, ancients referred to bamboo shoots as "intestine-scraping combs," indicating they should be used temporarily rather than long-term.
Zhu Xu (Bamboo Borers' Frass): Refers to the frass found in old, withered bamboo. The residual Qi of bamboo remains; its taste is sweet and neutral, and it is non-toxic. Sweetness detoxifies, and neutrality disperses. Bamboo has the coolest nature among plants, making it a divine herb for draining pus and promoting tissue regeneration. Combined with Ivory (Elephantis Dentis Massa), Pearl (Margarita), and Alum (Alumen), it can eliminate fistulas. For foul-smelling purulent discharge from the ear, mix equal parts of Zhu Xu and Carminous Embryo (Carmeni Foetum), add a small amount of Moschus (Moschus), grind into powder, and insufflate into the ear. If ear pus causes pain due to water entering the ear, mix 1 qian of Zhu Xu, 1 qian of Calomelas (Hydrargyri Chloridum Commune), and 5 fen of Moschus into powder. Clean the ear canal thoroughly with a cotton swab, insert the medicine, and block the ear with cotton. Allow any foul matter to drain out. Severe cases will heal after three applications. For damp-toxemia sores, mix equal parts of Zhu Xu and Phellodendri Cortex (Phellodendri Chinensis Cortex). Wash the lesion with scallion and pepper tea, pick at it, and apply once daily for effectiveness. For burns and scalds, applying Zhu Xu powder also leads to healing.
