（沉香是树木心材中的节结部分。放入水中会下沉，因此得名“沉水”，也称为“水沉”。半浮半沉的称为栈香，完全漂浮不沉的称为黄熟香。凡是要使用沉香，必须选择不干枯的。如果像兽角一样坚硬沉重，能沉入水底的是上品；半沉的次之。不可用火烤。如果要制作丸药或散剂，用纸包裹后放在怀里待其干燥后再研磨。或者放入乳钵中加水磨成粉，晒干也可以使用。如果用于煎煮汤剂，只需磨取汁液，在临服时加入即可。）
【气味】
味辛，微温，无毒。属阳。具有升和降的作用。（咀嚼时有香甜味的，性质平和；有辛辣味的，性质偏热。）
【主治】
风水引起的毒肿，去除恶气。主治心腹疼痛、霍乱、中恶邪鬼疰气（指感受不正之气导致的突发疾病）。能清心醒神，适宜用酒煮后服用。各种疮疡肿痛适宜加入膏药中使用。能调理中焦，补益五脏，益精壮阳，温暖腰膝，停止转筋、呕吐腹泻及冷气。能破除症癖（腹部积块）、冷风麻痹、骨节不能承受风湿侵袭、皮肤瘙痒。治疗气痢，补益右肾命门，补益脾胃以及因脾虚导致的痰涎和出血。能益气安神，治疗上热下寒，气逆喘急，大肠虚闭，小便气淋，男子精冷。
【气味】
味苦、辛，温，无毒。又气味淡薄而滋味浓厚。属于阳中之阴。可升可降。
【主治】
橘皮味苦能泻能燥，味辛能散能温。能补能和。能化痰止咳，顺气理中，调和脾胃宽胸膈。通利五淋，治疗饮酒过度引起的病症。它的功效应当在其他药物之上，都是取其理气燥湿的功效。与补药同用则起补益作用，与泻药同用则起泻下作用，与升药同用则起升提作用，与降药同用则起沉降作用。脾是元气的母亲，肺是摄气的仓库。所以橘皮是作用于这两条经络气分的药物，只是随着配伍不同而产生补、泻、升、降的不同效果。所以洁古张氏说：陈皮和枳壳能利气，痰自然下降。大概就是这个道理。与杏仁同用治疗大肠气滞，与桃仁同用治疗大肠血瘀，都是取其疏通阻滞的作用。
(The heartwood knots of the tree. It sinks in water, hence the name Chenxiang (Aquilaria Wood), also called Shuichen (Water Sinking). Half-sinking is called Zhanxiang (Stacked Agarwood), and non-sinking is called Huangshuxiang (Yellow Ripe Agarwood). When using Chenxiang (Aquilaria Wood), one must select pieces that are not withered. Those that are hard and heavy like animal horns and sink to the bottom of the water are considered superior; those that are half-sinking are secondary. Fire should be avoided. For use in pills or powders, wrap it in paper and keep it in one's bosom until dry before grinding. Alternatively, grind it into powder in a mortar with water and then dry it. If used in decoctions, only grind it to extract juice and add it just before administration.)
[Flavor and Properties]
Acrid, slightly warm, non-toxic. Yang in nature. It has ascending and descending actions. (Those that taste sweet and fragrant when chewed have a neutral nature; those that taste pungent and spicy have a hot nature.)
[Indications]
Edematous swelling caused by wind-water toxins; eliminates foul qi. Mainly treats abdominal pain, Huoluan (Cholera-like syndrome), Zhong'e (Sudden collapse due to evil qi), and Zhuqi (Infectious diseases attributed to ghostly influences). Clears and calms the Shen (Spirit). Suitable for decoction with wine. For various sores and swellings, it is suitable for inclusion in plasters. Regulates the Middle Jiao, tonifies the five Zang organs, benefits essence and strengthens Yang, warms the waist and knees, stops muscle twitching, vomiting, diarrhea, and cold qi. Breaks up masses (Zhengpi) and cold wind-induced numbness, joints unable to withstand wind-dampness, and skin itching. Treats Qi Li (Dysentery characterized by gas), tonifies the Right Kidney and Mingmen (Gate of Life), tonifies the Spleen and Stomach, and addresses phlegm and bleeding originating from the Spleen. Benefits Qi and calms the Spirit. Treats Upper Heat and Lower Cold, rebellious Qi causing asthma and urgency, deficiency-closure of the Large Intestine, Qi-type strangury, and cold sperm in men.
[Flavor and Properties]
Bitter, acrid, warm, non-toxic. The aroma is light while the flavor is strong. It is Yin within Yang. It can ascend and descend.
[Indications]
The bitterness of Chendi (Aged Tangerine Peel) allows for purging and drying; its acridity allows for dispersing and warming. It can tonify and harmonize. It resolves phlegm and treats cough, smooths Qi and regulates the Middle Jiao, harmonizes the Spleen and relieves chest fullness. Unblocks the Five Stranguries, treats alcohol-induced ailments. Its efficacy surpasses many other herbs, primarily due to its ability to regulate Qi and dry dampness. Combined with tonifying herbs, it tonifies; combined with purgative herbs, it purges; combined with ascending herbs, it ascends; combined with descending herbs, it descends. The Spleen is the mother of Yuan Qi (Original Qi), and the Lung is the repository of Qi. Therefore, Chendi (Aged Tangerine Peel) is an herb that acts on the Qi aspect of these two meridians, producing tonifying, purging, ascending, or descending effects depending on its compatibility. Thus, Zhang Jiegu said: Chendi (Aged Tangerine Peel) and Zhike (Aurantii Fructus) benefit Qi movement, and phlegm naturally descends. This is the principle. Combined with Xingren (Armeniacae Semen Amarum), it treats Large Intestine Qi stagnation; combined with Taoren (Persicae Semen), it treats Large Intestine Blood stasis, both utilizing their ability to unblock stagnation.
