【桃仁】
味苦、甘，性平，无毒。需去除外皮和尖端。生用时能调和血液，连皮和尖端一起炒制则能破除瘀血。与干漆拌和后炒制，可大力破除陈旧性瘀血。双仁的桃核有毒，不可使用。
《神农本草经》记载其主治瘀血、血闭、症瘕（腹内结块）及邪气，能杀灭三虫。
【发明】
桃仁入足厥阴肝经和手厥阴心包经的血分，是治疗血瘀、血闭的专用药物。苦味能泄除滞血，甘味能生成新血，但总体而言破血的功效占多数。从《神农本草经》的主治功效可以看出，张仲景所用的桃核承气汤、抵当汤，都是取其破血的作用。此外，还用于治疗热邪侵入血室导致的瘀积、症瘕、经闭、疟母（疟疾形成的腹部肿块）、心腹痛、大肠便秘等，也是利用其消散肝经血结的功效。将其熬香后治疗疝气疼痛瘙痒，这是《千金方》中的方法。桃实（桃子）味甘酸，多吃会让人腹部发热并导致腹泻。桃奴（树上未落而枯死的桃子）能驱杀百鬼精物，治疗中恶引起的腹痛、瘀血症及坚硬积聚，破血时需用酒磨服；止血时则烧成灰服用。桃树上的树胶最能通利津液，能治疗血淋、石淋、痘疮黑陷，必胜膏中就使用了它。桃叶治疗传尸劳（肺结核等慢性消耗性疾病），有水炙法：用桃叶一斗，艾叶、厚朴各二两，分装两个袋子，加入几斤火酒煮沸，交替煮药，熨烫患病人的背部，直到酒喝完为止，不超过三次，即可彻底断绝痨虫。另外，对于疮疡中的小虫，捣烂后涂抹患处。
【栗子】
味咸，性温，无毒。
【发明】
栗子是肾之果，肾病适宜食用。风干的栗子可以直接吃。如果是脾肾虚寒引起的急性腹泻，必须烤熟或煮熟后食用。栗楔（栗子中间劈开的部分）一球包含三颗，其中扁平的那颗，能治疗筋骨风湿痛，又能破除冷积癖块。生嚼栗楔敷在恶刺（带毒的刺伤）处，能拔出箭头，栗楔肉上那层薄皮就是栗楔皮。烧至存性（保留药效的炭化状态），治疗骨头卡在喉咙里，吹入喉中即可排出。栗壳煮汁治疗反胃和消渴病。毛球（栗子外面的带刺外壳）煮汁洗治火丹毒肿。栗花治疗瘰疬（颈部淋巴结结核）。栗树皮煮汁洗治沙虱溪毒以及丹毒疮毒。栗子根治疗偏坠（疝气）和肾气病，用酒煎服。
[Tao Ren (Peach Seed)]
Bitter, sweet, neutral in nature, non-toxic. Remove the skin and sharp ends. When used raw, it harmonizes blood; when stir-fried with skin and ends, it breaks blood stasis. Stir-fried with dry lacquer, it powerfully resolves old blood stasis. Peach kernels with two kernels are toxic and should not be used.
*Shennong Bencao Jing* states that it governs blood stasis, blood obstruction, zheng jia (abdominal masses), and evil qi, and kills three types of parasites.
[Invention/Commentary]
Tao Ren enters the blood aspect of the Foot-Jueyin Liver Meridian and Hand-Jueyin Pericardium Meridian, serving as a specific drug for blood stasis and blood obstruction. Its bitterness drains stagnant blood, while its sweetness generates new blood; however, its blood-breaking efficacy predominates. This is evident from the indications in *Shennong Bencao Jing*, which shows that Zhang Zhongjing’s Taohe Chengqi Decoction (Peach Pit Draining the Lower Jiao Decoction) and Didang Tang (Wait-For-It Decoction) both utilize its blood-breaking properties. Furthermore, it treats heat entering the Blood Chamber causing blood accumulation, zheng jia, amenorrhea, nuomu (malaria spleen), heart and abdominal pain, and large intestine constipation, all by dispersing blood knots in the Liver Meridian. When roasted until fragrant, it treats hernia pain and itching, a method from *Qianjin Fang*. The fruit of the peach is sweet and sour; excessive consumption causes abdominal heat and diarrhea. Taonu (dried peaches remaining on the tree) expels evil spirits and entities, treating sudden severe abdominal pain, blood stasis syndromes, and hard accumulations; to break blood, grind with wine and take; to stop bleeding, burn to ash and take. The gum from the peach tree best promotes fluid circulation, treating blood strangury, stone strangury, and black depression of smallpox lesions; Bisheng Ointment uses it. Tao Ye (Peach Leaf) treats chuan shi lao (consumptive disease like tuberculosis); there is a water-processing method: use one dou of peach leaves, two liang each of Ai Ye (Mugwort Leaf) and Houpo (Magnolia Bark), place them in two bags, boil with several jin of strong liquor, alternately boil the medicine, and apply hot compresses to the patient's back until the liquor is exhausted. Within three applications, the pathogenic worms are permanently eradicated. Additionally, for small insects in sores, crush and apply topically.
[Li (Chestnut)]
Salty, warm in nature, non-toxic.
[Invention/Commentary]
Li is the fruit of the Kidney, suitable for Kidney diseases. Dried chestnuts can be eaten directly. For acute diarrhea due to Spleen and Kidney deficiency-cold, they must be roasted or boiled before eating. Li Xi (the wedge-shaped kernel inside the shell), where one ball contains three kernels, specifically the flattened one, treats wind-pain in tendons and bones and breaks cold accumulation and癖块 (masses). Chewed raw and applied to malignant thorns (poisonous thorn injuries), it extracts arrowheads; the thin skin on the Li Xi meat is called Li Xi Pi. Burned to retain its medicinal property (charcoal form), it treats fishbones stuck in the throat; blowing it into the throat expels them. Li Qiao (Chestnut Shell) decocted in water treats regurgitation and Xiao Ke (wasting-thirst syndrome). Mao Qiu (the spiny outer husk) decocted in water washes Huo Dan Du Swelling. Li Hua (Chestnut Flower) treats Luo Li (scrofula). Li Shu Pi (Chestnut Tree Bark) decocted in water washes Sha Si Xi Du and Dan Du Chuang Du (erysipelas and sores). Li Gen (Chestnut Root) treated with wine decoction addresses Pian Zhui (hernia) and Shen Qi disorders.
