泻、破血润燥。
苦平微甘。苦以泄血滞，甘以缓肝气而生新血。（成无己曰∶肝者、血之源、血聚则肝
气燥
、肝苦急、急食甘以缓之。）通大肠血秘。治热入血室。（冲脉。）血燥血痞。损伤积血。血
痢经闭。咳逆上气。（血和则气降。）皮肤燥痒。（肌有血凝。）发热如狂。（若小腹满痛、小
便自利者、为畜血。）若非血瘀而误用之。大伤阴气。泡去皮尖炒。研碎。双仁者有毒。不
可用。香附为使。（妇人阴痒、桃仁杵烂、绵裹塞之、产后阴肿、桃仁捣研傅之、俱妙。）
桃花（通、大泻。） 苦平。下宿水。除痰饮。消积聚。利二便。疗风狂。（苏鹗杜阳编载、
范纯佑女、丧夫发狂、闭之室中、夜断窗棂、登桃树、食花几尽、自是遂愈、以能泻痰饮滞
血也。儒门事亲载、一妇滑泻数年、百治不效、或言此伤饮有积也、桃花落时、以棘针刺
取数十萼、勿犯人手、以面和作饼、煨熟食之、米饮送下、不一二时、泻下如倾、六日行至
数百行、昏困、唯饮凉水而平。）以攻决为用。但可施于气实有余之证。若无故而因除百病
、美颜色诸谬说而服之。为害不小。三月三日。采花拣净。以绢袋盛。悬檐下阴干。千叶者
勿用。
桃叶（宣、发汗、苦平。杀虫发汗。（凡伤寒风痹、发汗不出、以火烧地、用水洒
之、布干桃
叶于上、浓二三寸、席卧温复、取大汗、被中敷粉极燥、便瘥、凡麦麸蚕沙、皆可如此法
用。）采嫩者。名桃心。入药尤胜。桃子辛酸甘热。微毒。多食令人有热。生痈疖。（有损无
益、五果列桃为下、以此与鳖同食、患心痛、服术人尤忌之。）桃枭（是桃子在树、经冬不
落
者、正月采之。）苦微温。有小毒。辟邪祛祟。（白秃头疮、干桃一两、黑丑一合为末、腊猪
脂调搽。）
泻下瘀血，破除血结，滋润燥热。
味苦、性平，略带甘味。苦味能泄除血液瘀滞，甘味能舒缓肝气从而生成新血。（成无己说：肝脏是血液的源头，血液瘀聚则肝气干燥；肝气急迫时，食用甘味食物可以缓解它。）治疗大肠因血瘀导致的便秘。治疗热邪侵入血室（冲脉）。治疗血燥和血痞块。治疗外伤导致的积血。治疗血痢和月经闭止。治疗咳嗽气逆上冲。（血液调和则肺气下降。）治疗皮肤干燥瘙痒。（肌肉中有血液凝滞。）治疗发热如狂的症状。（如果小腹胀满疼痛、小便自利，则是畜血证。）如果不是血瘀证而误用此药，会严重损伤阴气。使用时需泡去皮尖，炒制后研碎。双仁桃仁有毒，不可使用。香附为其引经药。（妇女外阴瘙痒，将桃仁捣烂，用棉布包裹塞入阴道；产后外阴肿胀，将桃仁捣碎敷贴，效果都很好。）
桃花（功效通利，泻下作用强烈。）
味苦、性平。排出体内停留的水饮。消除痰饮。消散积聚。通利大小便。治疗风邪引起的发狂。（苏鹗《杜阳编》记载：范纯佑的女儿丧夫后发狂，被关在房间里，夜里咬断窗棂，爬上桃树，几乎吃光了桃花，从此病愈，因为桃花能泻除痰饮和瘀血。《儒门事亲》记载：一位妇女患滑泄数年，各种治疗无效，有人说这是伤于水饮且有积滞，桃花凋落时，用棘刺取下数十个花萼，不要用手直接接触，用面粉做成饼，煨熟食用，米汤送服，不到一两个时辰，腹泻如水倾泻，六天内排便数百次，出现昏困症状，只喝凉水才平息。）以攻逐决裂为作用特点。只能用于气实有余的病症。如果无故为了去除百病、美化容颜等谬论而服用，危害不小。三月三日采集花朵，拣选干净，用绢袋盛装，悬挂在屋檐下阴干。千叶桃花勿用。
桃叶（功效宣散，发汗，味苦、性平。杀虫，发汗。（凡是伤寒或风痹导致汗不出，可烧红地面，洒水，铺上厚二三寸的干桃叶，席卧其上，温覆取大汗，被中撒粉保持极干燥，即可痊愈。凡麦麸、蚕沙，都可以用这种方法。）采集嫩叶。名为桃心。入药效果更佳。桃子味辛、酸、甘，性热。微毒。多吃令人产生内热，生痈疖。（有损无益，五果中以桃列为下等，因此与鳖同食会引起心痛，服用白术的人尤其忌讳。）桃枭（是挂在树上的桃子，经过冬天不掉落者，正月采集。）味苦，微温。有小毒。辟除邪气，驱除鬼祟。（治疗白秃头疮，用干桃仁一两，黑丑一合，研为末，用腊月猪脂调匀搽涂。）
Purgative, blood-breaking, and moistening for dryness.
Bitter, neutral, slightly sweet. Bitter flavor drains blood stasis; sweet flavor moderates Liver Qi to generate new blood. (Cheng Wuji stated: The Liver is the source of blood; when blood gathers, Liver Qi becomes dry. When the Liver suffers from urgency, sweet foods should be eaten to moderate it.) It unblocks constipation due to blood in the Large Intestine. It treats heat entering the Blood Chamber (Chong Mai). It treats blood dryness and blood痞 (masses). It treats accumulated blood from trauma. It treats bloody dysentery and amenorrhea. It treats cough with rebellious Qi. (When blood is harmonious, Qi descends.) It treats dry and itchy skin. (Blood coagulation in the muscles.) It treats fever resembling madness. (If there is fullness and pain in the lower abdomen with free urination, it is a case of蓄血 [accumulated blood].) If used mistakenly in cases without blood stasis, it severely damages Yin Qi. Preparation: Soak to remove the skin and tips, stir-fry, then crush. Double-kernel Peach Kernels are toxic and must not be used. Xiangfu (Cyperus Rhizome) serves as an guiding herb. (For women's vulvar itching, crush Peach Kernels, wrap in cotton, and insert vaginally; for postpartum vulvar swelling, crush and apply externally; both methods are excellent.)
Peach Blossom (Unblocking, strong purgative action.)
Bitter, neutral. Drains retained water. Eliminates phlegm-fluids. Dissolves accumulations. Promotes urination and defecation. Treats wind-induced madness. (Su E's *Duyang Bian* records: Fan Chunyou's daughter went mad after losing her husband. She was locked in a room, bit through window lattice at night, climbed a peach tree, and ate almost all the blossoms, after which she recovered, as blossoms can purge phlegm-fluids and blood stasis. *Rumen Shiqin* records: A woman suffered from slippery diarrhea for years with no effect from various treatments. Someone suggested this was due to injury by fluids and accumulation. At the time of peach blossom fall, dozens of calyces were harvested using thorns, avoiding direct hand contact. They were made into cakes with flour, baked/roasted, and taken with rice drink. Within one or two hours, diarrhea flowed like pouring; over six days, she had hundreds of bowel movements, became faint and exhausted, and only settled after drinking cold water.) Its function is aggressive resolution. It may only be applied to conditions of excess Qi and surplus. If taken without cause under the false pretenses of curing myriad diseases or beautifying complexion, the harm is considerable. Harvest flowers on the 3rd day of the 3rd lunar month, clean them thoroughly, store in silk bags, and dry in the shade hanging under eaves. Do not use thousand-petal varieties.
Peach Leaf (Dispersing, inducing sweating. Bitter, neutral. Kills parasites, induces sweating. (In cases of Shanghan or wind-bi where sweat cannot be induced, burn the ground, sprinkle water, lay thick layers of dry peach leaves 2-3 cun thick, lie on a mat upon them, cover warmly to induce profuse sweating, dust the bedding with powder to keep it extremely dry, and the condition will heal. Wheat bran and silkworm feces can be used similarly.)) Harvest tender leaves. Named "Peach Heart." Superior for medicinal use. Peach Fruit is pungent, sour, sweet, and hot. Slightly toxic. Excessive consumption causes internal heat and generates carbuncles/furuncles. (Harmful rather than beneficial; among the five fruits, Peach is ranked lowest; eating it with turtle meat causes heart pain; those taking Atractylodes macrocephala Rhizome especially avoid it.) Tao Xiao (Peach fruit that remains on the tree through winter without falling, harvested in the first lunar month.) Bitter, slightly warm. Slightly toxic. Expels evil spirits and malefic influences. (For treating white tinea capitis, mix one liang of dried Peach Kernel with one he of Hei Chou [Semen Stramonii], grind to powder, and apply mixed with lard from the twelfth lunar month.)
