夏枯草，味苦，气温。曰寒者，误。入肺、脾、心三经。专散痰核鼠疮，尤通心气，头
目之
火可祛，胸膈之痞可降。世人弃而不收，谁知为药笼中必需之物乎。夫肺气为邪所壅，则清
肃之令不行，而痰即结于胸膈之间而不得散。倘早用夏枯草，同二陈汤煎服，何至痰核之生
。心火炎上，则头目肿痛，而痰即结于胸膈而成痞。早用夏枯草，入于芩、连、天花粉之内
，何至头痛目肿乎。盖夏枯草直入心经，以通其气，而芩、连、花粉之类，得以解炎上之火
也。尤妙心火一平，引火下生脾土，则脾气健旺，而痰更消亡，鼠疮从何而生乎，《本草》
只言其破症坚、消寒热、祛湿痹，尚未深知夏枯草也。
或问夏枯草，近人亦知用之，但不能入之汤剂之内也，今欲用之，不知多寡宜若何耳？
夫夏
枯草，阴药也，阴药宜多用以出奇，而不可少用以待变也。
百部，味甘、苦，气微温而寒，无毒。专入肺经，亦入脾、胃。止肺热咳嗽上气，治传
尸骨
蒸，杀寸白蛔虫。洗衣除虱，烧汤洗牛马身，虱不生；烧烟薰树木，蛀虫即死；人家烧烬，
尽逐蠓蝇。此物杀虫而不耗气血，尤有益于人。但其力甚微，用之不妨多也，然必于参、茯
、、术、归、芎同用为佳。大约用百部自一钱为始，可用至三四钱止，既益肺、胃、脾之
气，又能杀虫。倘痨病有传尸之虫者，须用地骨、沙参、丹皮、熟地、山药共用为妙矣。
或问百部，杀虫之药未有不耗气血者，而百部何以独异乎？夫百部原非补剂，不补则攻，
然
而，百部非攻药也，乃和解之药，而性亦杀虫，能入于虫之内，而虫不知其能杀也。杀虫之
药，必与虫相斗，百部不特不斗，而并使虫之相忘其杀也，又何至有气血之耗哉。
或疑百部杀虫，何能使虫之不知？夫百部味甘，虫性喜甘，投其所好，妄甘味之能杀身
也。
故食之而不知耳，及至已食百部，而虫之肠胃尽化为水，欲作祟而不能，有不知其何以死而
死者矣。
夏枯草，味道苦，药性温。说它性寒是错误的。它进入肺、脾、心三经。专门消散痰核和鼠瘰（颈部淋巴结结核），尤其能疏通心气，祛除头目的火热，降下胸膈的痞闷。世人抛弃它而不重视，谁知道它是药柜中必需的物品呢？如果肺气被邪气壅塞，那么清肃下降的功能就不能正常行使，痰就会凝结在胸膈之间而无法消散。如果早点使用夏枯草，配合二陈汤煎服，怎么会生出痰核呢？心火炎上，就会导致头目肿痛，而痰就会凝结在胸膈形成痞块。早点使用夏枯草，加入黄芩、黄连、天花粉之中，怎么会头痛目肿呢？大概因为夏枯草直接入心经，以疏通心气，而黄芩、黄连、天花粉之类，能够解除炎上的火热。尤其奇妙的是，心火一旦平息，就能引火下行生养脾土，这样脾气健旺，痰就更易消亡，鼠瘰又从何而生呢？《本草》只说它能破除症坚、消除寒热、祛除湿痹，这还没有真正了解夏枯草啊。
有人问：夏枯草，近代人也知道使用它，但不能将其放入汤剂中。现在想要使用它，不知道用量多少合适？
夏枯草，是阴药，阴药应当多用以出奇制胜，而不可少用以等待病情变化。
百部，味道甘、苦，药性微温而带寒，无毒。专门进入肺经，也进入脾、胃经。停止肺热引起的咳嗽和气逆，治疗传尸劳（肺结核等慢性消耗性疾病）导致的骨蒸潮热，杀死寸白虫（绦虫）。用它洗衣可以去除虱子，煮汤洗牛马身体，虱子就不会再生；烧烟熏树木，蛀虫就会死亡；人家焚烧它的灰烬，能驱逐蠓蝇。这种药物杀虫却不耗损气血，尤其对人有益。但是它的力量很微弱，使用不妨多一点，然而必须与人参、茯苓、白术、当归、川芎同用才好。大约使用百部从一钱开始，可以用到三四钱为止，既能补益肺、胃、脾之气，又能杀虫。如果是痨病有传尸虫的，必须用地骨皮、沙参、丹皮、熟地黄、山药共同使用才妙。
有人问：百部，杀虫的药物没有不耗损气血的，为什么百部唯独不同呢？原来百部并非补剂，不补就是攻伐，然而，百部也不是攻伐药，而是和解之药，其性质也能杀虫，能进入虫子体内，而虫子不知道它能杀自己。杀虫的药，必定与虫子相斗，百部不仅不斗，反而让虫子忘记自己被杀，又怎么会耗损气血呢？
有人怀疑百部杀虫，怎么能让虫子不知道？因为百部味道甘，虫子的本性喜欢甘味，投其所好，妄自贪图甘味而导致丧命。所以吃的时候并不知道，等到吃了百部之后，虫子的肠胃都化为水，想作祟而不能，有不知道自己是怎么死的就死了。
Xia Kugu Cao (Prunella vulgaris), with a bitter taste and warm temperature. The assertion that it is cold is erroneous. It enters the Lung, Spleen, and Heart meridians. It specializes in dissipating phlegm nodules and scrofula (lymphatic tuberculosis), and particularly unblocks Heart Qi, dispelling fire from the head and eyes, and reducing stagnation in the chest and diaphragm. People discard it and do not value it; who knows that it is an essential item in the medicine cabinet? When Lung Qi is obstructed by pathogenic factors, its clear descending function fails to operate, causing phlegm to knot between the chest and diaphragm without dispersing. If Xia Kugu Cao were used early on, decocted and taken with Er Chen Tang (Two-Aged Powder), how could phlegm nodules arise? When Heart Fire flares upward, it causes swelling and pain in the head and eyes, while phlegm knots in the chest and diaphragm forming stagnation. If Xia Kugu Cao were used early on, combined with Huang Qin (Scutellariae Radix), Lian Zi (Coptidis Rhizoma), and Tian Hua Fen (Trichosanthis Radix), how could headache and eye swelling occur? This is because Xia Kugu Cao directly enters the Heart meridian to unblock its Qi, allowing Huang Qin, Lian Zi, and Tian Hua Fen to resolve the flaming-upward fire. Especially wonderful is that once Heart Fire is pacified, it guides the fire downward to generate Spleen Earth, thereby strengthening Spleen Qi and further eliminating phlegm; from where would scrofula arise? Ben Cao (Compendium of Materia Medica) only states that it breaks hardness of masses, eliminates alternating chills and fever, and expels damp bi-syndrome; this has not yet deeply understood Xia Kugu Cao.
One asks: Xia Kugu Cao, contemporary people also know to use it, but cannot put it into decoctions. Now wishing to use it, one does not know what the appropriate dosage should be?
Xia Kugu Cao is a Yin herb; Yin herbs should be used in large doses to achieve unexpected results, and should not be used in small doses waiting for changes.
Bai Bu (Stemonae Radix), with sweet and bitter tastes, slightly warm yet cold in nature, non-toxic. It specifically enters the Lung meridian, and also enters the Spleen and Stomach meridians. It stops cough and rebellious Qi due to Lung heat, treats bone-steaming associated with transmissive consumption (tuberculosis), and kills Taenia solium (pork tapeworm). Washing clothes with it removes lice; boiling water to wash cattle and horses prevents lice from growing; burning it to smoke trees kills wood-boring insects; burning its ashes in households drives away midges and flies. This substance kills insects without depleting Qi and Blood, which is particularly beneficial to humans. However, its power is very slight, so using more is acceptable, but it is best used together with Ren Shen (Ginseng Radix et Rhizoma), Fu Ling (Poria), Bai Zhu (Atractylodis Macrocephalae Rhizoma), Dang Gui (Angelicae Sinensis Radix), and Chuan Xiong (Ligustici Chuanxiong Rhizoma). Generally, start with one qian of Bai Bu, usable up to three or four qian, which benefits Lung, Stomach, and Spleen Qi while killing insects. If consumptive disease involves transmissive worms, it is excellent to combine it with Di Gu Pi (Lycii Cortex), Sha Shen (Adenophorae Radix seu Glehniae Radix), Mu Dan Pi (Moutan Cortex), Shu Di Huang (Rehmanniae Radix Preparata), and Shan Yao (Dioscoreae Rhizoma).
One asks: Insect-killing medicines invariably deplete Qi and Blood, why is Bai Bu unique? Originally, Bai Bu is not a tonic; if not tonifying, it attacks. However, Bai Bu is not an attacking medicine, but a harmonizing medicine. Its nature also kills insects; it can enter inside the insects, and the insects do not know it can kill them. Insect-killing medicines must fight against the insects; Bai Bu not only does not fight, but makes the insects forget they are being killed, so how could there be depletion of Qi and Blood?
One doubts: How can insect-killing allow the insects to remain unaware? Because Bai Bu has a sweet taste, and the nature of insects likes sweetness. By catering to their preferences, they foolishly crave the sweet taste leading to their death. Thus, they eat without knowing. Only after consuming Bai Bu do the insects' intestines and stomachs turn into water; wanting to cause trouble but unable to, they die without knowing how they died.
