苞（花蕾）
气味辛温。气清而香。味薄而散。性浮而升，属阳。归入手太阴肺经和足阳明胃经。川芎为其引经药。主治风邪引起的头脑疼痛、面部肿胀牵引牙齿疼痛。通鼻塞流涕。治疗鼻渊（鼻窦炎）、鼻鼽（过敏性鼻炎）、鼻疮、鼻窒（慢性鼻炎）。以及痘疹后出现的鼻疮。（均研成粉末，加入麝香使用）
〔论〕 辛夷所使用的是其花蕾部分。它在正二月开花，花落之后才长出叶子。叶子之间随即含有花芽。经过伏夏历冬。花芽中的阳气与足太阳膀胱经同行走。所以鼻渊虽然是脑部疾病，但症状必然表现在鼻子。即使鼻塞、鼻鼽，虽然未尝病于脑，但不能归于阴极，而是阴中之阳逐渐滋长。就像阳气蓄积在地中一样。到了三阳交泰的时候，蓄积在阴中的阳气顿时宣发。就像阳气通达于天一样。蓄积在地而通达于天，犹如人身之真阳首在于足太阳，依附于足阳明。至于像脑冷以及肾虚脑漏之类的病症（属于脑类虚证），虽然各有适宜的方剂，但必须以辛夷这味药为关键枢纽。不能仅仅因为它是辛温之品就认为它会导致壅滞。脑者属阴。又说何以能充髓于脑，而使阴也通达于上呢？
其性质辛香走窜，气虚的人不宜使用。头痛属于血虚火炽的，以及齿痛属于胃火的，都禁用。（仲淳评注）
〔修事〕 去除绒毛，以免刺激射入人肺。去掉木质心，不致使人烦躁。水洗，微炒。
沉香
辛苦微温。体重。气浓味薄。可升可降。入胃、脾、肾经。兼入心、肝经。咀嚼起来香甜的性平。辛辣的性热。主治调理中焦、消除怯弱。安神、养护诸气。去除恶气。止冷气。降真气。开结气。破症癖（积聚肿块）。治疗上热下寒。气逆喘急。补右肾命门。补脾胃及痰涎。血出于脾，能治大肠虚闭、小便气淋。禀受阳气以生长，兼得雨露之精气而结成，所以其气芬芳。是治疗冷气、逆气、气郁、气结的要药。（仲淳评注）
上而至天，下而及泉，与其他药物配合使用最为适宜。（东垣评注）行气而不伤气，温中而不助火。只有气虚下陷的人，忌用。（士材评注）保和卫气，为上品药。单独使用则势力微弱，与其他药物相佐助，应当缓慢取效。有益无害。
神枣朱雀丸：服用方法涉及胞转（膀胱扭转或排尿困难）。药方可通也。沉香一两，肉苁蓉酒浸二两，各研成粉末，以麻仁研汁糊丸，梧桐子大小。
〔论〕 沉香木得水气方才结成，多在折断的树枝枯干中。（或者是枝干因水朽烂而凝结）。又得到朝阳长久的照射，而膏脉凝聚。大抵禀受地之阳，而酝酿于天之阴。而且其他香气疏导滞气，而沉香的适宜于气郁气结的情况不同。木香升降滞气，而沉香祛寒开胃，而沉香调中止冷、保和卫气的情况不同。檀香升发清阳，而沉香的情况不同。虽然说是独行则势力微弱，然而它是阴阳气化所凝结，终究不是禀受草木专气的东西。中气虚者，忌用。心经有实邪者，忌用。非命门真火衰者，不宜入下焦药用。（仲淳评注）
〔辨治〕 须要选择不枯干的，如嘴角硬重，沉于水下的最好。半沉的次之。不可见火。入煎剂，磨汁使用。
It is suitable to harvest when the flowers have not yet opened. Collect in the first and second lunar months.
Buds (Flower Buds)
The flavor is pungent and warm. The aroma is clear and fragrant. The taste is thin and dispersing. It floats and ascends; it belongs to Yang. It enters the Hand Taiyin Lung Meridian and the Foot Yangming Stomach Meridian. Chuanxiong Rhizoma (Chuanxiong, 川芎) serves as its guiding herb. It primarily treats wind-induced headache and facial pain, facial swelling radiating to toothache. It unblocks nasal congestion with discharge. It treats rhinitis purulenta (Nasal Sinusitis), allergic rhinitis (Nasal Allergy), nasal sores, and chronic nasal obstruction (Chronic Rhinitis). As well as nasal sores occurring after smallpox/variolous eruptions. (All are ground into powder and mixed with Moschus (Musk, 麝香)).
[Discussion] The part of Xin Yi used is the bud. Its flowers bloom in the first and second lunar months. Leaves grow only after the flowers fall. Between the leaves, flower buds are contained. These buds endure the summer heat and winter cold. The Yang energy within the buds travels along with the Foot Taiyang Bladder Meridian. Therefore, although rhinitis purulenta is a disease originating from the brain, its symptoms must manifest through the nose. Even if it is merely nasal congestion or allergic rhinitis, which do not originate from the brain, they cannot be attributed to extreme Yin. Instead, the Yang stored within Yin gradually grows, similar to Yang accumulating in the earth. When the time comes for the interaction of the Three Yangs, the Yang stored within Yin suddenly disseminates, just as Yang reaches the heaven. Accumulating in the earth and reaching the heaven is like the True Yang of the human body residing in the Foot Taiyang and attaching to the Foot Yangming. Regarding conditions such as cold brain or kidney deficiency leading to brain leakage (nasal drip due to kidney deficiency), although there are specific appropriate formulas, this herb must serve as the key pivot. One must not simply assume that because it is pungent and warm, it causes stagnation. The brain is considered Yin. It is also asked how it can fill the marrow in the brain and allow Yin to reach the upper body?
Its nature is pungent, fragrant, and penetrating. It is unsuitable for those with Qi deficiency. Headaches caused by Blood deficiency and blazing Fire, as well as toothaches caused by Stomach Fire, are strictly contraindicated. (Commentary by Zhong Chun)
[Processing] Remove the hairs to avoid irritating the lungs. Remove the woody core to prevent causing restlessness. Wash with water, and stir-fry lightly.
Agarwood (Chen Xiang)
Pungent, bitter, slightly warm. Heavy in weight. Strong aroma, thin taste. It can ascend and descend. Enters the Stomach, Spleen, and Kidney meridians. Also enters the Heart and Liver meridians. Those that taste sweet and fragrant when chewed have a neutral nature. Those that taste spicy and hot have a hot nature. It primarily regulates the Middle Jiao, dispels timidity/weakness. Calms the Spirit, nourishes various Qi. Removes foul odors. Stops cold sensations. Descends True Qi. Opens stagnant Qi. Breaks accumulations and masses. Treats Upper Heat and Lower Cold. Treats rebellious Qi with panting and urgency. Tonifies the Right Kidney Mingmen. Tonifies the Spleen and Stomach, and resolves phlegm-saliva. Since blood originates from the Spleen, it can treat deficiency-closure of the Large Intestine and Qi-type strangury. It inherits Yang Qi to generate, and combines with the essence of rain and dew to form, thus its aroma is fragrant. It is an essential herb for treating cold qi, rebellious qi, Qi stagnation, and Qi knotting. (Commentary by Zhong Chun)
Reaching up to Heaven and down to Springs, it pairs best with other herbs. (Commentary by Dong Yuan) It moves Qi without damaging Qi, warms the Middle without assisting Fire. Only those with Qi deficiency and sinking are contraindicated. (Commentary by Shi Cai) It protects and harmonizes Wei Qi, making it a superior grade herb. Used alone, its effect is weak; assisted by other herbs, it should be taken slowly for results. It is beneficial and harmless.
Shenzao Zhuque Wan: Indications include bladder torsion (difficulty in urination). The prescription allows for passage. Agarwood (Chen Xiang, 沉香) one liang, Cistanche Stem (Rou Cong Rong, 肉苁蓉) soaked in wine two liang, each ground into powder. Use Sesame Seed juice (Hemp Seed Juice) to make pills the size of wu-tong seeds.
[Discussion] Agarwood forms when wood absorbs water, mostly found in broken branches and dry trunks. (Or formed where branches/trunks have rotted due to water). Furthermore, receiving long exposure to the morning sun causes the resinous veins to condense. Generally, it inherits Earth's Yang and brews Heaven's Yin. Other aromatic herbs guide stagnant Qi, but Agarwood is different in its suitability for Qi stagnation and knotting. Wood Aromatic (Mu Xiang) raises and lowers stagnant Qi, whereas Agarwood dispels cold and opens the stomach; their functions differ. Sandalwood (Tan Xiang) raises clear Yang, whereas Agarwood differs. Although it is said that acting alone makes its power weak, since it is condensed from the interaction of Yin and Yang Qi, it is ultimately not a substance inheriting the specialized Qi of simple plants. Those with deficient Middle Qi should avoid it. Those with Excess pathogenic factors in the Heart Meridian should avoid it. Unless there is a decline of True Fire in the Mingmen, it is not suitable for use in lower Jiao prescriptions. (Commentary by Zhong Chun)
[Differentiation and Treatment] One must select pieces that are not dried out. Those that are hard and heavy at the edges and sink to the bottom of water are best. Those that float halfway are secondary. Avoid exposure to fire. For decoctions, grind into juice for use.
