补肾
咸温。浓肠胃，补肾气（寇宗 曰∶小儿不可多食。生则难化，熟则滞气。能解羊膻）。
能燥能宣，有补有泻，可升可降
辛能散，苦能燥、能泻，温能补、能和。同补药则补，泻药则泻，升药则升，降药则降
。为脾、肺气分之药（脾为气母，肺为气龠。凡补药涩药，必佐陈皮以利气）。调中快膈，
导滞消痰（大法治痰，以健脾顺气为主。洁古曰∶陈皮、枳壳利其气，而痰自下），利水破
症，宣通五脏，统治百病，皆取其理气燥湿之功（人身以气为主，气顺湿除，则百病散。《金
匮》云∶能解鱼毒、食毒）。多服久服，损人元气。入补养药则留白，入下气消痰药则去白
（《圣济》云∶不去白，反生痰）。
去白名橘红，兼能除寒发表（皮能发散皮肤）。核治疝痛。叶散乳痈（皆能入厥阴，行
肝气，消肿散毒。腰肾冷痛，橘核炒酒服良。《十剂》曰∶宣可去壅，生姜橘皮之属是也。《
泊宅编》曰∶莫强中，食已辄胸满不下，百治不效。偶家人合橘皮汤，尝之似有味，连日饮

散之患。半夏亦然，故同用名二陈汤）。治痰咳，童便浸晒。治痰积，姜汁炒。治下焦，盐
水炒。去核、皮，炒用。
补肾。味咸，性温。（寇宗奭说：小儿不宜多吃。生吃难以消化，熟吃容易阻滞气机。能解除羊肉的膻味）。
具有燥湿和宣通的作用，既有补益又有泻实的效果，既能升提又能下降。辛味能发散，苦味能燥湿、能泻下，温性能补益、能调和。与补药同用则起补益作用，与泻药同用则起泻实作用，与升提药同用则起升提作用，与降逆药同用则起降逆作用。它是作用于脾、肺二经气分的药物（脾为生气之源，肺为气之枢纽。凡是使用补益药或收敛涩滞药时，必须佐以陈皮来疏通气机）。调理中焦，宽胸利膈，引导积滞消除痰饮（治疗痰证的大法，以健脾顺气为主。洁古说：陈皮、枳壳能疏通气机，气顺则痰自降），利水消肿，破除癥瘕积聚，宣通五脏，统管多种疾病，都是取其理气燥湿的功效（人体以气为主，气顺则湿除，百病自散。《金匮要略》说：能解鱼毒、食毒）。多服久服，会损伤人的元气。入补养药方中则保留白瓤，入降气消痰药方中则去掉白瓤（《圣济总录》说：不去白瓤，反而生痰）。
去掉白瓤的叫橘红，兼能驱寒发表（皮能发散皮肤表邪）。果核治疗疝气疼痛。叶子散治乳痈（都能入厥阴经，疏行肝气，消肿解毒。腰肾冷痛，橘核炒酒后服用效果好。《十剂》说：宣可去壅，生姜、橘皮之类就是。《泊宅编》记载：有人强迫进食，吃完就胸满不下，各种治疗无效。偶然家人煮橘皮汤，尝起来似乎有味道，连续几天饮用。一天坐在厅堂，觉得胸中有物坠下，瞪眼出汗，大惊扶归，腹部疼痛，排出数块如铁丸般的硬物，臭不可闻，从此胸中豁然开朗。这是脾脏的冷积，半年服药不知效，功效全在橘皮。方用橘皮一斤，甘草、盐各四两，煮干后点服，名叫二贤散。蒸饼为丸，名叫润下丸。治疗痰证特别有效。世间的医生只知道半夏、南星、枳壳、茯苓之类，哪里配谈论这个呢！丹溪说：治痰，利药过多则脾虚，痰易生而反多。又说：胃气也依赖痰来滋养，不可攻尽，攻尽则虚而更严重）。广东产的陈久者好，所以叫陈皮（陈久则烈气消散，无燥散之患。半夏也是如此，所以同用名叫二陈汤）。治疗痰咳，用童便浸泡晒干。治疗痰积，用姜汁炒制。治疗下焦病证，用盐水炒制。去掉核和皮，炒用。
Tonifies the Kidney. Salty and warm in nature. (Kou Zongshi stated: Children should not consume it excessively. Raw consumption is difficult to digest, while cooked consumption may stagnate Qi. It can resolve the gamey odor of mutton.)
It possesses the ability to dry dampness and disperse, having both tonifying and purgative effects, capable of ascending and descending. The pungent flavor can disperse, the bitter flavor can dry dampness and purge, and the warm nature can tonify and harmonize. When combined with tonifying herbs, it tonifies; when combined with purgative herbs, it purges; when combined with ascending herbs, it ascends; when combined with descending herbs, it descends. It is a herb that acts on the Qi level of the Spleen and Lung meridians (The Spleen is the mother of Qi, and the Lung is the bellows of Qi. Whenever tonifying or astringent herbs are used, Chenpi must be added as an assistant to facilitate Qi movement). It regulates the Middle Jiao, relieves chest fullness, guides out stagnation, and eliminates phlegm (The general principle for treating Phlegm focuses on strengthening the Spleen and smoothing Qi. Jiegu said: Chenpi and Zhike facilitate Qi movement, and once Qi flows smoothly, Phlegm naturally subsides). It promotes diuresis, breaks up masses, unblocks the Five Viscera, and treats various diseases, all due to its merit in regulating Qi and drying dampness (The human body relies primarily on Qi; when Qi is smooth and dampness is removed, myriad diseases dissipate. The *Jin Gui Yao Lue* states: It can resolve fish poison and food poisoning). Excessive or long-term consumption damages the body's Original Qi. When included in tonifying formulas, the white pith is retained; when included in formulas for descending Qi and eliminating phlegm, the white pith is removed (The *Sheng Ji Zong Lu* states: If the white pith is not removed, it generates Phlegm instead).
When the white pith is removed, it is called Juhong, which additionally dispels cold and releases the exterior (The peel can disperse pathogens from the skin). The seeds treat hernia pain. The leaves disperse mastitis (All parts can enter the Jueyin meridian, circulate Liver Qi, reduce swelling, and dissipate toxicity. For cold pain in the lower back and kidneys, roasted Juhé taken with wine is effective. The *Shi Ji* states: 'Xuan' (Dispersing) can remove obstruction, exemplified by Shengjiang and Jupi. The *Bo Zhai Bian* records: A person forced to overeat experienced persistent chest fullness after meals, resisting all treatments. Accidentally, a family member prepared a Jupi soup, which tasted pleasant. After drinking it for several days, while sitting in the hall, he felt something drop in his chest, stared blankly, sweated profusely, was greatly alarmed, and was helped home. He suffered abdominal pain and passed several iron-ball-like hard stools, foul-smelling. From then on, his chest felt clear. This was cold accumulation in the Spleen, undetected by half a year of medication; the efficacy lay solely in Jupi. The formula uses one jin of Jupi, four liang each of Gancao and Yan, boiled until dry and taken as a paste, named Erxian San. Made into pills with steamed dough balls, it is named Runxia Wan. It is particularly effective for treating Phlegm. Physicians of the world only know Banxia, Nanting, Zhike, and Fuling; how can they discuss this? Danxi said: In treating Phlegm, excessive use of draining herbs leads to Spleen deficiency, causing Phlegm to generate easily and increase. He also said: Stomach Qi also relies on Phlegm for nourishment; it cannot be completely attacked, for doing so leads to deficiency and worsens the condition). Chenpi from Guangdong that has been aged for a long time is superior, hence the name Chenpi (Aging dissipates its harsh energy, avoiding adverse drying and dispersing effects. Banxia is similar, hence their combination is named Erchen Tang). To treat Phlegm cough, soak in child's urine and sun-dry. To treat Phlegm accumulation, stir-fry with ginger juice. To treat Lower Jiao disorders, stir-fry with salt water. Remove the core and peel, and stir-fry before use.
