泻肺降火
苦平。清肺和胃而降气，气下则火降痰消（气有余便是火，火则生痰）。治热咳、呕逆、
口渴（时珍曰∶火降痰顺，则逆者不逆，呕者不呕，咳者不咳，渴者不渴矣。一妇肺热久嗽
，身如火炙，肌瘦将成劳。以枇杷叶、款冬花、紫菀、杏仁、桑皮、木通等分，大黄减半，
蜜丸樱桃大。食后、夜卧各含化一丸，未终剂而愈）。叶湿重一两，干重三钱为气足，拭净
毛（毛射肺，令人咳）。治胃病，姜汁炙；治肺病，蜜炙。
宣，清肺
甘涩而温。肺、胃之果，清咽生津，除烦醒酒，解河豚毒（投入煮佳）及鱼骨鲠（如无
橄榄，以核磨水服。橄榄木作舟楫，鱼拨即浮出，物之相畏有如此者）。
核，烧灰，敷疰疳良。
一名银杏
涩，敛肺，去痰
甘苦而温。性涩而收。熟食温肺益气（色白属金，故入肺），定痰哮，敛喘嗽，缩小便，
止带浊。生食降痰解酒，消毒杀虫（花夜开，人不得见，性阴，有小毒，故能消毒杀虫）。
多食则收涩太过，令人壅气胪胀，小儿发惊动疳（食千枚者死）。
浆，泽手面，浣油腻（时珍曰∶去痰浊之功，可以类推）。
涩肠，外用染须
酸涩而温。能涩肠，止泻痢下血（ 末服），崩带脱肛（泻痢至于脱肛者，以石榴皮、
陈壁土加明矾少许，浓煎熏洗，再用五倍子炒研、敷托而止之）。浸水，汁黑如墨，乌须方
绿云油中用之。勿犯铁器（《客座新闻》云∶一人患腹胀，夏成诊曰∶饮食如常，非水肿蛊
胀，乃湿热生虫之象也。以石榴、椿树东引根皮、槟榔各五钱，空心服，腹大痛，泻虫长丈
余，遂愈）。
泻肺降火
味苦，性平。能清泄肺热、调和胃气并降逆下气，气机下行则火势下降、痰液消除（中医认为气机郁滞过剩便会化火，火热之邪煎熬津液则生痰）。用于治疗热性咳嗽、呕吐呃逆、口渴等症状。（李时珍说：火降则痰顺，气逆者不再上逆，呕吐者不再呕吐，咳嗽者不再咳嗽，口渴者不再口渴了。曾有一位妇女因肺热久咳不止，身体发热如火烤，肌肉消瘦几乎形成虚劳病。用枇杷叶、款冬花、紫菀、杏仁、桑白皮、木通各等分，大黄减半的量，制成如樱桃大小的蜜丸。饭后及睡前各含服一丸，药未服完病就好了）。叶片湿润时重一两，干燥后重三钱为气味充足。需拭净绒毛（绒毛刺激肺部，会引起咳嗽）。治疗胃病时，用姜汁炙烤；治疗肺病时，用蜂蜜炙烤。
宣肺，清咽生津
味甘、涩，性温。是肺和胃的果实，能清利咽喉、生津止渴，解除烦闷、解酒毒，并能解河豚鱼毒（放入锅中煮食效果佳）以及鱼骨卡喉（如果没有橄榄，可将橄榄核磨成水服用。橄榄木可制作船桨，鱼拨动即浮出水面，万物之间相互制约的道理就是这样）。
果核，烧成灰，外敷治疗疰气和疳积症疗效良好。
一名银杏
味涩，能收敛肺气，去除痰浊
味甘、苦，性温。性质涩而具有收敛作用。熟食可温补肺脏、益气（颜色白色对应五行中的金，故入肺经），安定痰哮，收敛气喘咳嗽，缩小便次数，止住白带浑浊。生食可降低痰浊、解酒毒、消毒杀虫（花朵在夜间开放，人无法看见，其性属阴，有小毒，因此能消毒杀虫）。多吃会导致收敛涩滞太过，使人气机壅滞、腹部胀满，小儿食用会引发惊风或疳积（吃一千枚者会死亡）。
浆液，能使手面润泽，清洗油腻（李时珍说：去除痰浊的功效，可以由此类推）。
涩肠，外用染发
味酸、涩，性温。能涩肠止泻，治疗腹泻、痢疾及便血（研末内服），崩漏、带下及脱肛（对于因腹泻痢疾导致的脱肛，可用石榴皮、陈年墙壁土加少许明矾，浓煎后熏洗患处，再用五倍子炒研后敷托即可止血止脱）。浸泡水中，汁液黑如墨汁，用于乌须发，常加入绿云油中使用。不要接触铁器（《客座新闻》记载：有一人患腹胀病，夏季成诊断说：饮食正常，不是水肿或蛊胀，而是湿热生虫的现象。用石榴、椿树向东生长的根皮、槟榔各五钱，空腹服用，腹中剧烈疼痛，排出长达一丈多的虫子，于是痊愈）。
To drain the Lung and descend fire.
Bitter, neutral in nature. Clears the Lung, harmonizes the Stomach, and descends Qi; when Qi descends, fire subsides and phlegm dissipates (excess Qi generates fire, and fire generates phlegm). Indicated for heat-type cough, vomiting/reversal of Qi, and thirst. (Shizhen said: When fire subsides and phlegm flows smoothly, reversal ceases, vomiting stops, coughing halts, and thirst is quenched. A woman suffered from chronic cough due to Lung heat, her body felt as hot as a furnace, and she was emaciated, bordering on consumption. Equal parts of Piyepian (Loquat Leaf), Kuandonghua (Fritillaria Flower), Ziwan (Aster Root), Xingren (Apricot Seed), Sangbaipi (Mulberry Bark), Mutong (Akebia Stem), with half the amount of Dahuang (Rhubarb), were made into honey pills the size of cherries. One pill was held in the mouth after meals and before sleep until cured, without finishing the course). Leaves weigh one tael when moist and three qian when dry, indicating sufficient Qi potency. The downy hairs must be wiped off (hairs irritate the Lung, causing cough). For Stomach disorders, stir-fry with ginger juice; for Lung disorders, stir-fry with honey.
Disperses, clears the Lung.
Sweet, astringent, warm in nature. The fruit of the Lung and Stomach meridians, it clears the throat, generates fluids, relieves restlessness, resolves alcohol intoxication, and detoxifies pufferfish poison (boiling with it is effective) and fish bone impaction (if no olive is available, grind the olive pit into water and drink. Olive wood can make oars; fish flip up immediately, demonstrating how substances mutually restrain each other).
The seed, burned to ash, applied externally is excellent for treating zhu-gan (chronic wasting conditions and malnutrition in children).
Also known as Yinxing (Ginkgo Nut).
Astringent, astringes the Lung, removes phlegm turbidity.
Sweet, bitter, warm in nature. Its nature is astringent and convergent. Cooked food warms the Lung and benefits Qi (its white color corresponds to Metal, thus entering the Lung meridian), stabilizes phlegmatic asthma, astringes wheezing and cough, reduces urination frequency, and stops leukorrhea turbidity. Raw food reduces phlegm, resolves alcohol toxicity, and eliminates parasites/toxins (flowers open at night, unseen by humans, possessing Yin nature and slight toxicity, thus capable of eliminating toxins and killing parasites). Excessive consumption leads to excessive astringency, causing Qi stagnation and abdominal distension; in children, it may induce convulsions or gan syndrome (consuming 1000 nuts causes death).
The pulp/juice moisturizes hands and face, and cleans grease (Shizhen said: its ability to remove phlegm turbidity can be inferred analogously).
Astringes the Intestines, used externally for dyeing hair.
Sour, astringent, warm in nature. It astringes the intestines, stops diarrhea/dysentery and bloody stool (take as powder), metrorrhagia/metrostaxis, leukorrhea, and rectal prolapse (for rectal prolapse caused by severe diarrhea/dysentery, decoct Shiliupi (Pomegranate Rind), Chenbitu (Old Wall Soil), and a small amount of Mingfan (Alum) strongly, fumigate and wash the area, then apply fried and powdered Wubeizi (Chinese Gall) to support and stop it). Soaked in water, the juice is black as ink, used to darken beard/hair, often mixed with Lüyun You (Green Cloud Oil). Do not contact iron vessels (Kuzu Xinwen records: A man suffered from abdominal distension. Xia Cheng diagnosed: Normal diet indicates it is not edema or gu-distension, but damp-heat generating worms. He prescribed Shiliu (Pomegranate), Chunshu Dongyin Genpi (Eastern-root bark of Toona sinensis), and Binglang (Betel Nut), each 5 qian, taken on an empty stomach. Severe abdominal pain followed, expelling worms over ten zhang long, and he recovered).
