\r吴茱萸\ph339.bmp\r，生上谷川谷及冤句，今处处有之，江浙，蜀汉尤多。木高丈
余，皮青绿色；叶似椿
而阔浓，紫色；三月开花，红紫色；七月、八月结实，似椒子，嫩时微黄，至成熟则深紫。
九月九日采，阴干。《风土记》曰∶俗尚九月九日谓为上九，茱萸到此日气烈熟色赤，可折
其房以插头，云辟恶气御冬。又《续齐谐记》曰∶汝南桓景随费长房学。长房谓曰∶九月九
日汝家有灾厄，宜令急去家，各作绛囊盛茱萸以系臂上，登高饮菊花酒，此祸可消。景如言
，举家登高山，夕还见鸡、犬、牛、羊一时暴死。长房闻之曰∶此代之矣。故世人每至此日
登高饮酒，戴茱萸囊，由此耳。世传茱萸气好上，言其冲膈，不可为服食之药也。张仲景
治呕而胸满者，茱萸汤主之。吴茱萸一升，枣二十枚，生姜一大两，人参一两，以水五升，
煎取三升，每服七合，日三。干呕吐涎沫而头痛者，亦主之。又其南行枝，主大小便卒关格
不通，取之断度如手第二指中节，含之立下，出姚僧垣方。根亦入药用。删繁方疗脾劳热
，有白虫在脾中，为病令人好呕者，取东行茱萸根，大者一尺，大麻子八升，橘皮二两，凡
三物 咀，以酒一斗，浸一宿，微火上薄暖之，三下，绞去滓，平旦空腹服一升取尽，虫便
下出，或死，或半烂，或下黄汁。凡作药法，禁声，勿语道作药，虫便下验。
吴茱萸，生长在上谷的川谷以及冤句等地，如今各地都有出产，江浙、蜀汉地区尤其多。植株高出一丈多，树皮呈青绿色；叶片形状像椿树但更宽厚浓密，颜色为紫色；三月开花，花色红紫；七月、八月结果实，果实形状像花椒籽，嫩时微黄，成熟后变为深紫色。九月九日采收，阴干。《风土记》记载：风俗崇尚九月九日为“上九”，此时的茱萸气味猛烈、色泽红润，可以采摘其花房插于头上，据说能辟除邪气、抵御寒冬。又据《续齐谐记》记载：汝南人桓景跟随费长房学习。费长房对他说：“九月九日你家将有灾厄，应当让你急忙离开家，各自制作红色口袋盛装茱萸系在手臂上，登高并饮用菊花酒，这场祸患便可消除。”桓景照做，全家登上高山，傍晚回家时看见鸡、狗、牛、羊一时之间突然死亡。费长房听说后说：“这是代替你们承受了灾祸。”所以世人每到这一天就登高饮酒，佩戴茱萸囊，就是由此而来。世间流传的说法认为茱萸之气好向上冲，意指其冲击胸膈，因此不可作为服食养生之药。张仲景治疗呕吐且胸中胀满者，用茱萸汤为主方。吴茱萸一升，大枣二十枚，生姜一大两，人参一两，用水五升，煎取三升，每次服用七合，每日三次。对于干呕、吐涎沫且头痛者，也适用此方。另外，其向南生长的枝条，主治大小便突然闭塞不通（关格），取该枝条折断至如人手第二指中间一节长短，含在口中，立刻见效，出自姚僧垣的方子。根部也可入药使用。《删繁方》治疗脾劳热，脾中有白虫，致病使人容易呕吐，取向东生长的茱萸根，粗大的一尺长，大麻子八升，橘皮二两，共三味药切碎，用酒一斗，浸泡一夜，在微火上保持温热，加热三次，绞去药渣，清晨空腹服用一升直至服完，虫子便会排出，有的已死，有的半烂，有的排出黄色汁液。凡是制药的方法，禁止出声，不要谈论制药之事，否则药效不显。
Evodiae Fructus (Wuzhuyu), originally growing in the river valleys of Shanggu and Yuanju, is now available everywhere, particularly abundant in Jiangzhe and Shu-Han regions. The shrub grows over one zhang high, with greenish-blue bark; leaves resemble those of Toona sinensis (Chun tree) but are broader and denser, appearing purple; flowers bloom in March, reddish-purple in color; fruits mature in July and August, resembling peppercorns, pale yellow when tender, turning deep purple upon full maturity. Harvested on the ninth day of the ninth lunar month, dried in the shade. *Fengtu Ji* records: "Customs esteem the ninth day of the ninth month as 'Shangjiu'; by this date, Evodiae Fructus has a strong aroma, ripe appearance, and red color. Its calyxes can be picked and inserted into hair to ward off evil qi and resist winter cold." Additionally, *Xu Qi Xiang Ji* states: Huan Jing from Runan studied under Fei Changfang. Fei Changfang told him, "On the ninth day of the ninth month, your household will face disaster. You should urgently leave home, each making a crimson pouch filled with Evodiae Fructus to tie around the arms, ascend high places, drink chrysanthemum wine, and this misfortune can be avoided." Huan Jing followed this advice, leading his entire family up a high mountain. Upon returning in the evening, they found that chickens, dogs, cattle, and sheep had suddenly died at once. Hearing this, Fei Changfang said, "These animals have taken the disaster upon themselves." Thus, people every year on this day ascend high places to drink wine and wear Evodiae pouches, originating from this event. It is commonly believed that Evodiae Fructus has an ascending nature, meaning it rushes upward to the chest and diaphragm, so it is not considered suitable for dietary tonic use. Zhang Zhongjing treated vomiting accompanied by chest fullness using Evodia Decoction (Zhuyu Tang). The prescription consists of Evodiae Fructus (Wuzhuyu) 1 sheng, Ziziphus Jujuba Fruit (Dazao) 20 pieces, Zingiberis Rhizoma Recens (Shengjiang) 1 da liang, Ginseng Radix et Rhizoma (Renshen) 1 liang. Boil these in 5 sheng of water to obtain 3 sheng. Take 7 he per dose, three times daily. For dry retching, spitting of saliva, and headache, this formula is also indicated. Furthermore, branches growing southward treat sudden obstruction of urination and defecation (Guan Ge). Take a piece broken to the length of the middle joint of the second finger of the hand, hold it in the mouth, and relief follows immediately; this comes from Yao Sengyuan's formula. The root is also used medicinally. *Shanfan Fang* treats Spleen Labor Heat with white worms in the spleen, causing frequent vomiting. Take Evodiae Fructus roots growing eastward, large ones one chi long, Cannabis Fructus (Damaizi) 8 sheng, Citri Reticulatae Pericarpium (Jupi) 2 liang. These three ingredients are crushed, soaked in one dou of wine overnight, kept warm over low fire for three cycles, strained to remove dregs, and taken one sheng on an empty stomach at dawn until finished. The worms will then be expelled, either dead, half-rotten, or excreted as yellow fluid. Regarding all medicinal preparation methods, silence is prohibited; do not speak about preparing medicine, otherwise the efficacy regarding worm expulsion will not manifest.
