味酸，性大热有毒，入命门经。主下焦虚冷，阳绝不起，头秃，疽痔癣疥，心腹 癖，
脚膝冷疼，虚损泄精。莹净无夹石者良，甘草汤煮过用，畏朴硝、细辛、飞廉，忌百般禽兽
血。
按∶硫黄为火之精，宜入命门补火，盖人有真火，寄于右肾，苟非此火，则不能有生。
此火一熄，则万物无父，非硫黄孰与补者。太清云∶硫禀纯阳，号为将军，破邪归正，返浊
还清，挺立阳精，消阴化魄。戴元礼云∶热药皆燥，惟硫黄不燥，则先贤常颂之矣。今人绝
不用之，诚虞其热毒耳，然有火衰之证，余此莫疗。亦畏而遗之可乎？中其毒者，以猪肉、
鸭羹、余甘子汤解之。
雷公云∶凡使勿用青赤色，及半白半黄、半赤半黑者。自有黄色如雏鸡初出壳者为真。
凡硫四两，先以龙尾蒿自然汁一镒，东流水三镒，紫背天葵汁一镒，粟逐子茎汁四镒，合之
搅匀，入瓦锅，用六一泥固济底下，将硫黄碎之，入于锅中，以前件药汁，旋旋添入水煮之，
汁尽为度。再以百部末十两，柳虫末二斤，一簇草二斤，细锉之，以东流水并药等同煮硫黄
二伏时，去诸药，取出用甘草汤洗了，入钵中，研二万遍，方妙。
味辛苦，性温无毒，入肺肝脾胃四经。主下气消食，化痰破结，止呕咳，定霍乱，疗吐
泻，利小便，通五淋，逐膀胱留热，杀寸白诸虫，核治腰痛疝痛，叶治乳痈胁痈，肉能止渴，
多食令人气逆生痰。去白者兼能除寒发表，留白者兼能补胃和中，微炒用，产广中，陈久者
良。
按∶陈皮辛苦之性，能泄肺部。金能制水，故入肝家，土不受侮，故入脾胃，采时性已
极热，如人至老成，则酷性渐减，收藏又复陈久，则多历梅夏，而烈气全消，温中而无燥热

【硫黄】
味酸，性大热且有毒，归入命门经。主治下焦虚寒、阳气衰竭无法振奋、头发脱落、疽疮痔疮癣疥、心腹部积聚痞块、脚膝冷痛、虚损导致的遗精滑泄。以晶莹洁净无夹杂石头的为佳，用甘草汤煮过后使用，畏朴硝、细辛、飞廉，忌食各种禽兽血。
按语：硫黄是火的精华，适宜归入命门以补火。大概人拥有真火，寄居在右肾，如果不是这团火，就不能维持生命。这团火一旦熄灭，万物就失去了根本（如同无父），除了硫黄还有谁能补益它呢？太清说：硫黄禀受纯阳之气，号称将军，能破除邪气回归正道，使浑浊返归清澈，挺立阳精，消除阴邪转化魄神。戴元礼说：热药大多燥烈，唯独硫黄不燥烈，这是先贤常常称颂的。现在的人完全不用它，确实是担心它的热毒罢了，然而对于阳气衰微的证候，没有比硫黄更能治疗的了。因为畏惧而遗弃它，可以吗？中毒者，用猪肉、鸭羹、余甘子汤来解毒。
雷公说：凡是使用的硫黄不要选用青赤色，以及半白半黄、半赤半黑的。自有黄色像雏鸡刚出壳的是真品。
凡是四两硫黄，先用龙尾蒿的自然汁一镒，东流水三镒，紫背天葵汁一镒，粟逐子茎汁四镒，混合搅拌均匀，放入瓦锅中，用六一泥密封加固锅底，将硫黄捣碎，放入锅中，以前述的药汁，慢慢加入水煮，直到药汁烧干为止。再用百部粉末十两，柳虫粉末二斤，一簇草二斤，细细切碎，用东流水和药物一起煮硫黄两个时辰（伏时），去掉所有药物，取出后用甘草汤清洗，放入钵中，研磨两万遍，才算是妙法。
【陈皮】
味辛苦，性温无毒，归入肺、肝、脾、胃四经。主治降气消食、化痰破结、止呕咳、平定霍乱、治疗呕吐腹泻、通利小便、通治五淋、驱逐膀胱滞留的热邪、杀灭寸白虫等寄生虫，果核主治腰痛疝痛，叶子治疗乳痈胁痈，果肉能止渴，多吃令人气逆生痰。去除白色内瓤的兼能散寒发表，保留白色内瓤的兼能补胃和中，微炒后使用，产于广中地区，陈久的为佳。
按语：陈皮辛苦的性质，能宣泄肺部。金能制水，所以归入肝家；土不受侮，所以归入脾胃。采摘时其性已经极热，就像人到了老年成为老人，那么暴烈的性格逐渐减少，收藏又经过陈久，经历梅雨夏季，那么烈气完全消散，温中而没有燥热的性质。
[Sulfur]
Taste: Sour. Nature: Extremely hot, toxic. Meridian Tropism: Mingmen (Gate of Life) meridian. Indications: Lower jiao deficiency-cold, Yang exhaustion with failure to rise, alopecia, carbuncles, hemorrhoids, tinea, scabies, epigastric and abdominal masses (Pi), cold pain in feet and knees, deficiency-induced seminal emission. The best quality is bright, clean, and free from stone impurities. It should be boiled in Licorice Decoction before use. It is incompatible with Mirabilite (Puxiao), Asarum (Xixin), and Leontodon (Feilian). It is contraindicated with the blood of various poultry and beasts.
Commentary: Sulfur is the essence of Fire, suitable for entering the Mingmen to tonify Fire. Humans possess True Fire, which resides in the right kidney; without this Fire, life cannot be sustained. Once this Fire extinguishes, all things lose their "father" (origin); who else but Sulfur can tonify it? Taiqing states: Sulfur inherits pure Yang energy, is known as the General, breaks evil to return to righteousness, transforms turbidity into clarity, stands firm in Yang essence, and eliminates Yin to transform Po spirit. Dai Yuanli states: Hot herbs are generally drying, but Sulfur is not drying; this has been frequently praised by sages. Nowadays, people absolutely do not use it, truly fearing its heat toxicity. However, for syndromes of declining Fire, there is no better remedy than Sulfur. Is it acceptable to discard it out of fear? For those poisoned by it, detoxification can be achieved using pork meat, duck soup, or Phyllanthus emblica (Yuganzi) decoction.
Lei Gong states: When using Sulfur, do not use those that are green-red, half-white half-yellow, or half-red half-black. The true product is yellow like a chick just hatching from an egg.
For four liang of Sulfur, first mix one yi of natural juice from Longwei Hao (Artemisia longipes?), three yi of East-flowing water, one yi of juice from Zibei Tiankui (Ophiopogon japonicus var. bulbifer?), and four yi of juice from Suzhuzi stem. Stir well, place in a clay pot, seal the bottom with Liuyi Mud (Six-to-One Mud). Crush the Sulfur, put it in the pot, and slowly add the aforementioned herbal juices to boil until the liquid is exhausted. Then, take ten liang of powder of Stemona (Baibu), two jin of powder of Willow insect (Liuchong), two jin of Yicucao (One-cluster grass), finely chop them, and boil the Sulfur together with East-flowing water and these herbs for two fushi (four hours). Remove all herbs, take out the Sulfur, wash it with Licorice Decoction, place it in a mortar, and grind it twenty thousand times to achieve the desired effect.
[Chenpi / Aged Tangerine Peel]
Taste: Pungent, bitter. Nature: Warm, non-toxic. Meridian Tropism: Lung, Liver, Spleen, Stomach meridians. Indications: Directs Qi downward, promotes digestion, resolves phlegm, breaks stagnation, stops vomiting and coughing, stabilizes Huoluan (cholera-like syndrome), treats vomiting and diarrhea, promotes urination, treats five types of strangury (Wulin), expels lingering heat from the bladder, kills roundworms (Cunbai), fruit seeds treat lower back pain and hernia pain, leaves treat mastitis and hypochondriac abscesses, flesh quenches thirst. Excessive consumption causes Qi rebellion and phlegm generation. Removing the white pith enhances the ability to dispel cold and release the exterior; retaining the white pith enhances the ability to tonify the Stomach and harmonize the middle. Use after slight stir-frying. Produced in Guangzhong region; aged peel is superior.
Commentary: The pungent and bitter nature of Chenpi can vent the Lung. Metal controls Water, so it enters the Liver home; Earth is not insulted, so it enters the Spleen and Stomach. At the time of harvesting, its nature is extremely hot, like a person becoming old, where the fierce temperament gradually diminishes. After storage and aging, passing through plum rain and summer seasons, the fierce energy completely dissipates, warming the middle without causing dryness-heat.
