川黄连禀受天地清寒之气而生，因此气味苦寒且无毒。其味重于气，味苦而浓烈，属于阴。适宜向下泄降，若想使其上行，必须加入引导药。有的用酒拌炒，有的用姜汁拌炒，有的与吴茱萸同蒸，都是因为苦寒之性太过，通过这种炮制方法稍微减弱其药性，这是古人“用寒远寒”（使用寒凉药时要避开寒凉环境或体质）的深意。
川黄连配合木香治疗下痢，配合枳壳治疗痔疮，配合官桂服用可使心肾在顷刻间相交。能镇肝、凉血、调胃、厚肠、益胆、泻心、燥湿、开郁、除烦、解渴、杀虫、安蛔、利水、明目、除痞、消疳。清除心火郁热，治疗阳毒发狂、暑热下痢、酒毒痞满、惊悸、肠风，各种恶疮湿热郁热皆能治疗。凡是病患血少气虚、脾胃薄弱、虚烦躁渴，以及产后血虚、发热泄泻腹痛，一切似痢非痢的症状，都应当严格禁忌。胡黄连，治疗骨蒸劳热、温疟多热、久痢成疳、疳积久痢，补肝胆，缓解目痛；一切由湿热邪热、阴分伏热所生的疾病，无不消除；小儿盗汗劳热；妇人胎蒸虚惊。
主治（痘疹合参）：川黄连，泻心火。凡是痘疹血热而热毒盛者，以及在酷暑季节患痘疹而又血热者，都必须用酒拌炒。如果在痘疹未发出时忌服，恐怕导致冰伏（邪气被寒凉药遏制不能透发）。然而五味入胃，各归其所喜好的脏腑，久服则增加该脏之气，这是事物变化的常理。所以久服黄连，反而从火化（因偏胜而产生火热之变），气增久了，偏胜的危害就会产生，夭折的原因就在这里，所以冲和平淡的药才能久服。
防风禀受天地阳气而生，因此味甘辛温且无毒。气浓味薄，主升，属阳。入手阳明经、足少阳经，是厥阴经的风药。治疗风病通用，具有升发而能疏散的作用。畏藜芦，能杀附子毒。
防风能杀乌头大毒，是足太阳膀胱经的本经药，又通行脾胃二经，地位如同卒伍般卑贱，听命即行，随引经药竟至病所。能尽治一身之疼痛，为风药中的润剂。治疗风病通用，散湿也容易，能消除身半以上的风邪，消除身半以下的风疾，收敛滞气于面颊，尤其能泻肺实有余，驱除眩晕头颅症状，开通目盲无见，搜肝顺气，治疗四体挛急，开腠理，托毒排脓治痈疽。大风、恶风、风邪周痹、头面游风、眼赤多泪，都是清除上焦风邪的要药。如果误服，反而会泻人上焦元气。在治疗药物中使用它，是因为风能除湿，且能宣扬药势。必须兼用荆芥，是因为防风入气分，荆芥入血分。
主治（痘疹合参）：凡是痘疹初起，风热发表不可缺少的药物。如疮疡搔痒者，与黄芩同用；手足不起发者，与白芍、桂枝同用，须以酒炒；疮太湿者用之，因为风能胜湿。疮干者亦用之，因为它能作为药中的润剂。所以说：利热解毒，和血止痒。但是不可久用，因为其味辛纯阳，终究属于走散耗血的性质。
按语：防风虽然是祛风祛湿的仙药，但它是辛温走泄之品，肺虚、气虚、血虚、火燥者，服用它需谨慎（原文此处语义未完，通常指慎用或需配伍，依文意译为需谨慎或避免单独大量使用，但根据指令不增添内容，故直译其警示意味）。
Chuan Huanglian (Coptidis Rhizoma) is born from the clear and cold qi of heaven and earth; therefore, its flavor is bitter and cold, and it is non-toxic. Its flavor is heavier than its aroma; being bitter and dense, it belongs to Yin. It is suitable for downward draining. If one wishes to make it ascend, guiding herbs must be added. Some stir-fry it with wine, some with ginger juice, and some steam it with Evodiae Fructus (Wuzhuyu). This is because its bitter-cold nature is too strong, and such processing slightly reduces its properties, reflecting the profound meaning of the ancients' principle of "avoiding cold when using cold" (using cold-natured herbs with caution in cold conditions or constitutions).
When combined with Aucklandiae Radix (Muxiang), Chuan Huanglian treats dysentery; when combined with Aurantii Fructus (Zhike), it treats hemorrhoids; when taken with Cinnamomi Cortex (Guixin), it facilitates the interaction between the Heart and Kidneys in an instant. It calms the Liver, cools blood, regulates the Stomach, thickens the intestines, benefits the Gallbladder, drains Heart fire, dries dampness, resolves depression, relieves irritability, quenches thirst, kills parasites, calms roundworms, promotes urination, brightens the eyes, removes fullness, and eliminates childhood malnutrition. It clears stagnant heat of Heart fire, treats mania caused by Yang toxicity, summer-heat dysentery, alcohol-induced fullness, palpitations, intestinal wind, and various malignant sores due to damp-heat and stagnant heat. For patients with insufficient blood and Qi, weak Spleen and Stomach, false irritability and thirst, as well as postpartum blood deficiency, fever, diarrhea, abdominal pain, and all conditions resembling but not being dysentery, it should be strictly contraindicated.
Hu Huanglian (Scutellariae Barbatae Rhizoma, often referred to as Scutellariae Radix in this context or specifically *Barbatiscutellaria*) treats bone-steaming consumptive fever, warm malaria with excessive heat, chronic dysentery leading to malnutrition, and malnutrition with chronic dysentery. It tonifies the Liver and Gallbladder, alleviates eye pain; it eliminates all diseases arising from damp-heat, pathogenic heat, and latent heat in the Yin aspect. It treats childhood night sweats and consumptive fever, and maternal fetal steaming with false fright.
Main Indications (Integration of Smallpox and Rashes): Chuan Huanglian drains Heart fire. For smallpox cases with blood heat and盛 (excessive) heat toxicity, or those occurring in intense summer heat with blood heat, it must be stir-fried with wine. It is contraindicated before the rash erupts, lest it cause "ice-stagnation" (trapping pathogens inside). However, the five flavors enter the Stomach and each return to their preferred organ; long-term use increases the Qi of that organ, which is the normal transformation of substances. Therefore, long-term use of Huanglian may transform into Fire due to excess; prolonged increase of Qi leads to imbalance and harm, which is the origin of premature death. Thus, only mild and bland herbs can be used for a long time.
Fangfeng (Saposhnikoviae Radix) is born from the Yang Qi of heaven and earth; therefore, its flavor is sweet, pungent, and warm, and it is non-toxic. Its aroma is dense while its flavor is thin; it ascends and belongs to Yang. It enters the Hand-Yangming Large Intestine Meridian and Foot-Shaoyang Gallbladder Meridian, serving as a Wind-dispersing herb for the Jueyin Liver Meridian. It is generally used for treating Wind disorders, possessing ascending, dispersing, and releasing properties. It is incompatible with Veratri Radix (Lilü) and can neutralize the toxicity of Aconiti Lateralis Radix Praeparata (Fuzi).
Fangfeng can neutralize the great toxicity of Aconiti Radix (Wutou). It is a primary herb of the Foot-Taiyang Bladder Meridian and also circulates through the Spleen and Stomach meridians. Its function is humble like a soldier, acting immediately upon command and reaching the disease site guided by other herbs. It treats pains throughout the body and serves as a moistening agent among Wind-dispersing herbs. It is generally effective for Wind disorders and easily dispels dampness. It eliminates Wind pathogenic factors above the middle of the body and Wind diseases below the middle of the body. It consolidates stagnant Qi in the cheeks, particularly draining excess Lung Shi (Excess syndrome). It drives away dizziness and head symptoms, restores vision in blindness, soothes the Liver and regulates Qi, treats tetany of the four limbs, opens the interstices (Couli), and expels pus from carbuncles and ulcers. It is a key herb for eliminating Upper Jiao Wind pathogenic factors, including severe Wind, aversion to Wind, Wind-Bi affecting the whole body, wandering Wind on the head and face, red eyes with excessive tearing. Misuse may drain the Yuan Qi of the Upper Jiao. In prescriptions, it is used because Wind can dispel Dampness and promote the dissemination of medicinal effects. It is often combined with Schizonepetae Herba (Jingjie) because Fangfeng enters the Qi level, while Jingjie enters the Blood level.
Main Indications (Integration of Smallpox and Rashes): At the initial stage of smallpox, Fangfeng is indispensable for releasing Wind-Heat externally. For itching lesions, it is used with Scutellariae Radix (Huangqin); for limbs failing to erupt, it is used with Paeoniae Radix Alba (Baishao) and Cinnamomi Ramulus (Guizhi), and must be stir-fried with wine. It is used for overly wet lesions because Wind can overcome Dampness. It is also used for dry lesions because it acts as a moistening agent within the prescription. Thus, it is said to: benefit heat, detoxify, harmonize blood, and stop itching. However, it should not be used for a long time, as its pungent and purely Yang nature ultimately scatters and consumes Blood.
Note: Although Fangfeng is a miraculous herb for dispelling Wind and Dampness, it is a pungent-warm, dispersing, and draining substance. [Caution advised for] Lung deficiency, Qi deficiency, Blood deficiency, and Fire-dryness constitutions.
