味甘苦，性温有小毒，入肺大肠二经。主胸中气逆而喘嗽，大肠气秘而难便，及喉痹喑
。痰结烦闷，金疮破伤，风热诸疮，中风诸证，蛇伤犬咬，阴户痛痒，并堪捣敷，沸汤泡
去皮尖炒用。得火良，恶黄芩黄 ，葛根，畏 草，解锡毒及中狗肉毒，双仁者能杀人，杏
子不可多食，能损筋骨眼目。
按∶杏仁入肺者，经所谓肺苦气上逆，急食苦以泻之是也。大肠则共肺为传送者也，宜
并入之。考《左慈秘诀》，称杏仁为草金丹，久服成仙，方书又云∶服杏仁者，往往至二三
年或泻，或脐中出物，皆不可治，二说相背，然杏仁主散，痰从腠理中发散而去，且有小毒。
则
雷公云∶凡使须以沸汤浸，少时去皮膜及尖，擘作二片，用白火石并乌豆杏仁三件，于
锅中下东流水煮，从巳至未，其杏仁色褐黄，勿用。修治一斤，用白火石一斤，乌豆三合，
水旋添，勿令间，断为妙也。
味苦甘，性平无毒，入肝大肠二经，主瘀血血闭，症瘕鬼邪，血燥便结，杀三虫，止心
痛。沸汤泡去皮尖炒用。花，主杀鬼疰，悦颜色，利二便，下诸虫。勿用千叶者，令人鼻衄。
毛，主血瘕积聚崩带诸疾。桃虫，主杀精鬼邪恶不祥，叶，主恶气客忤，阴户生虫痛痒，及
疮中虫。桃实，多食令人发热。
按∶桃仁行血，宜入肝经，性润，宜入大肠，典术云；桃为五木之精，故花仁子叶，俱
能压邪杀鬼。
雷公云∶凡使须泡去皮尖，用白术、乌豆二味，和桃仁，同于瓦锅中煮一伏时，后漉出，
用手擘作两片，其心黄如金色乃用之，花勿用。千叶者，能使人鼻衄不止目黄。凡用拣令净，
以绢袋盛，于檐下悬，令干，用鬼髑髅，勿使干桃子，其鬼髑髅，只是千叶桃花结子在树上
不落者，于十一月内采得，可为神妙。凡修事以酒拌蒸，从巳至未，焙干，以铜刀切片，焙
取肉用。
【杏仁】
味甘、苦，性温，有小毒，归肺经和大肠经。主治胸中气逆导致的喘咳，大肠气滞导致的大便困难，以及喉痹失音。对于痰结引起的烦闷、金疮破伤、风热引起的各种疮疡、中风引起的各种证候、蛇咬和狗咬伤、阴户疼痛瘙痒，都可以捣碎后外敷。使用时需用沸水浸泡，去皮尖后炒用。得火则功效更佳，畏恶黄芩、黄连、葛根，畏惧甘草，能解锡毒及食用狗肉引起的中毒。双仁的杏仁能致人死亡，杏子不可多吃，会损伤筋骨和眼睛。
按语：杏仁入肺经，正如经典所说“肺苦气上逆，急食苦以泻之”。大肠与肺互为表里，共同负责传导排泄，所以杏仁也宜并入大肠经。考证《左慈秘诀》，称杏仁为“草金丹”，长期服用可以成仙；而方书又记载：服用杏仁的人，往往在两三年内出现腹泻，或者肚脐中流出异物，这些都难以治愈。这两种说法相互矛盾。然而，杏仁主要作用是发散，能使痰液从腠理中发散出去，且本身有小毒。
雷公云：凡是使用杏仁，必须用沸水浸泡，短时间后去掉皮膜和尖端，掰成两片，用白火石、乌豆和杏仁三味药，在锅中加入东流水煮，从巳时到未时，如果杏仁颜色变成褐黄色，就不要用了。修治一斤杏仁，需用白火石一斤，乌豆三合，水要随时添加，不要中断，这是妙法。
【桃仁】
味苦、甘，性平，无毒，归肝经和大肠经。主治瘀血、血闭、症瘕积聚、鬼邪作祟、血燥导致的大便干结，能杀三虫，止心痛。使用时需用沸水浸泡，去皮尖后炒用。桃花，主治杀鬼疰，美容养颜，通利二便，驱除体内寄生虫。不要用千叶桃花，会导致鼻出血。桃毛，主治血瘕积聚、崩漏带下等各种疾病。桃虫，主治杀死精怪邪恶不祥之物。桃叶，主治恶气客忤（外邪侵袭），阴户生虫疼痛瘙痒，以及疮口中的寄生虫。桃实（桃子），多吃会让人发热。
按语：桃仁具有行血作用，适宜入肝经；性质滋润，适宜入大肠经。《典术》说：桃是五木之精，所以它的花、仁、果、叶，都能压制邪气、杀灭鬼魅。
雷公云：凡是使用桃仁，需要泡去外皮和尖端，用白术、乌豆两味药，与桃仁一起放在瓦锅中煮一个时辰（一伏时），然后捞出，用手掰成两片，其心呈现金黄色才可使用，桃花不用。千叶桃花，能使人鼻出血不止、目黄。凡是用桃仁，要挑选干净，用绢袋盛装，悬挂在屋檐下晾干。使用鬼髑髅（此处指代一种特殊的桃核或药材处理物，原文语境特殊，暂译字面意思），不要用干燥的桃子果实。所谓的鬼髑髅，只是指千叶桃花结在树上不落下的果实，在十一月内采集，可视为神妙之法。凡是修整加工，用酒拌蒸，从巳时到未时，焙干，用铜刀切片，焙取果肉部分使用。
[Apricot Seed / Xing Ren]
Taste: Sweet and bitter. Nature: Warm, slightly toxic. Meridians entered: Lung (Fei) and Large Intestine (Da Chang). Indications: Mainly treats wheezing and coughing due to rebellious Qi in the chest, difficult defecation due to Qi stagnation in the Large Intestine, as well as throat obstruction with loss of voice (Hou Bi Yin). For phlegm accumulation causing restlessness, traumatic injuries from metal weapons, various sores caused by wind-heat, various syndromes of stroke (Zhong Feng), snake bites, dog bites, and pain and itching of the vulva, it can be crushed and applied externally. Preparation: Soak in boiling water, remove the skin and tips, then stir-fry. It works better when processed with heat. Antagonistic herbs: Huang Qin (Scutellariae Radix), Huang Lian (Coptidis Rhizoma), Ge Gen (Puerariae Lobatae Radix); incompatible with Gan Cao (Glycyrrhizae Radix et Rhizoma). Detoxification: Resolves tin poisoning and toxicity from eating dog meat. Note: Apricot seeds with two kernels can be fatal. Apricots should not be eaten in excess, as they can damage sinews, bones, and eyesight.
Commentary: Apricot seed enters the Lung meridian, which aligns with the classic saying: "The Lung dislikes rebellious Qi; urgently use bitter flavors to drain it." The Large Intestine shares a interior-exterior relationship with the Lung and is responsible for transportation and excretion, so Apricot seed is also suitable for entering the Large Intestine meridian. According to *Zuo Ci Mi Jue*, Apricot seed is called "Grass Golden Elixir," and long-term consumption leads to immortality. However, medical formularies state that those who consume Apricot seed often suffer from diarrhea or discharge from the umbilicus after two or three years, conditions that are difficult to treat. These two theories contradict each other. Nevertheless, Apricot seed primarily has a dispersing action, allowing phlegm to dissipate through the interstices (Cou Li), and it possesses slight toxicity.
Lei Gong states: When using Apricot seed, soak in boiling water, briefly remove the skin membrane and tips, split into two halves. Boil with Bai Huo Shi (White Fire Stone), Wu Dou (Black Soybean), and Apricot seed in three parts, using flowing water from the east, in a pot from Si hour to Wei hour. If the Apricot seed turns brownish-yellow, do not use it. To process one jin (approx. 500g) of Apricot seed, use one jin of Bai Huo Shi and three he (approx. 300ml) of Wu Dou. Add water continuously without interruption, which is the optimal method.
[Peach Kernel / Tao Ren]
Taste: Bitter and sweet. Nature: Neutral, non-toxic. Meridians entered: Liver (Gan) and Large Intestine (Da Chang). Indications: Mainly treats blood stasis, blood obstruction, masses and accumulations (Zheng Jia), evil spirits, dryness of blood leading to constipation, kills three types of parasites, and stops heart pain. Preparation: Soak in boiling water, remove the skin and tips, then stir-fry. Peach Flower (Tao Hua): Mainly kills ghost-related diseases (Gui Zhu), beautifies complexion, promotes urination and defecation, and expels internal parasites. Do not use double-petaled peach flowers, as they cause epistaxis (Bi Nu). Peach Hairs (Tao Mao): Mainly treats blood masses, accumulations, metrorrhagia, and leukorrhea. Peach Insect (Tao Chong): Mainly kills demonic entities and evil influences. Peach Leaf (Tao Ye): Mainly treats malignant qi and sudden external pathogenic invasion (Ke Wu), parasitic infections causing pain and itching in the vulva, and parasites in sores. Peach Fruit (Tao Shi): Excessive consumption causes fever.
Commentary: Peach Kernel promotes blood circulation, making it suitable for the Liver meridian; its moistening nature makes it suitable for the Large Intestine meridian. *Dian Shu* states: "Peach is the essence of the five woods," therefore its flowers, kernels, fruits, and leaves can all suppress evil and kill ghosts.
Lei Gong states: When using Peach Kernel, soak to remove the skin and tips. Boil with Bai Zhu (Atractylodis Macrocephalae Rhizoma) and Wu Dou (Black Soybean) in a clay pot for one fu shi (approx. 2 hours). Then strain and split by hand. Use only if the kernel heart is golden yellow. Do not use the flower. Double-petaled peach flowers can cause persistent epistaxis and jaundice. Select clean kernels, store in a silk bag, and hang under the eaves to dry. Regarding "Ghost Skull" (Gui Du Lou - likely a specific traditional processing term or metaphorical reference to unshed fruit/nuts): Do not use dried peach fruits. The so-called "Ghost Skull" refers specifically to the fruit of the double-petaled peach that remains on the tree and does not fall, harvested in the eleventh month, considered a miraculous preparation. For final processing: Steam with wine from Si hour to Wei hour, dry-roast, slice with a copper knife, and dry-roast again to extract the flesh/kernel meat.
