【淫羊藿】
药性寒。味辛。无毒。主治阳痿及阴绝精伤之证。阴茎疼痛。通利小便。补益气力。坚定意志。（用羊脂拌炒）
淫羊藿药性寒，禀受自然界冬季属水的寒气，入足少阴肾经。味辛且无毒，禀受大地润泽属金的特性，入手太阴肺经。其气味下降多于上升，属性为阴。阴对应宗筋（男性外生殖器及其相关筋膜）。若肾水不足不能制约心火，火热亢盛则使宗筋失去刚性而导致痿软。淫羊藿入肾经且药性寒，寒性足以制约火热，从而使痿证自愈。所谓“绝伤”，是指阴液枯竭而精气损伤。药性寒能滋补水液，味辛能滋润，滋润则阴精充盈。茎，即玉茎（阴茎）。疼痛是因为火热郁结于体内。热邪用寒凉药物清除，郁结用辛散药物发散，所以能主治阴茎疼痛。小便的排出依赖气化功能，淫羊藿作为辛寒之品，能清肃肺气，故能通利小便。肺主气，肾统摄气，寒性药物补益肾气，辛味药物润肺，因此能补益气力。气力既已补益，内在滋养刚大之气，所以能坚定意志，因为肾藏志。
制方：
淫羊藿浸泡酒中饮用，治疗半身不遂（偏风）。治疗因津液枯竭导致的腰痛。与五味子、覆盆子制成丸剂，治疗三焦咳嗽。研成细末泡水漱口，治疗牙痛。
【巴戟天】
药性微温。味辛甘。无毒。主治大风邪气（严重的风邪致病）。阳痿不起。强健筋骨。安定五脏，补益中气。增强意志，补益气力。（用酒焙干）
巴戟天气性微温，禀受自然界春季升发的木气，入足厥阴肝经。味辛甘且无毒，禀受大地金、土两种味道，入足阳明燥金胃经。其气味均向上行，属性为阳。风气与肝相通，巴戟天入肝经，辛甘之性能发散，主治大风邪气，通过发散作用驱除邪气。阴对应宗筋。宗筋归属于肝，痿软不起，说明肝经已完全没有鼓动阳气的能力。巴戟天气温能补益阳气，所以主治此症。大概巴戟天治疗的是阳虚导致的阳痿，而淫羊藿治疗的是阴虚导致的阳痿。肝主筋，肾主骨，辛温之性补益肝肾，所以能强健筋骨。胃是五脏的根本，十二经脉之长，辛甘之味入胃，温性助长胃阳，则五脏都能安宁。胃属中央土，土温暖则中气自然补益。肾统摄气并藏志，巴戟天气温补益肝气，肝主决断（敢），肝气不衰弱，就不会耗损肾气，从而使意志和气力得到增益。
制方：
巴戟天与五味子、肉苁蓉、山茱萸、鹿茸、柏子仁、枸杞子、补骨脂同用，治疗阳痿。与鹿角、柏子仁、天冬、远志、莲须、覆盆子、黄柏同用，治疗夜间梦遗鬼交泄精。与大黄同用，治疗饮酒之人脚部疾病（脚气）。
[Epimedium]
The nature is cold. The flavor is acrid. It is non-toxic. It primarily treats impotence and injuries characterized by the exhaustion of Yin and essence. It alleviates pain in the penis, promotes urination, supplements Qi and strength, and stabilizes the will. (Stir-fried with sheep fat)
Epimedium has a cold nature, inheriting the water Qi of winter from heaven, entering the Foot-Shaoyin Kidney Meridian. Its acrid flavor and non-toxicity derive from the moistening metal property of earth, entering the Foot-Taiyin Lung Meridian. The descending aspect of its aroma and flavor exceeds the ascending, making it Yin in nature. Yin corresponds to the Zongjin (tendons of the genitalia). If Kidney Water fails to control Fire, excessive Heat causes the tendons to lose their rigidity, resulting in flaccidity. Epimedium enters the Kidney meridian and possesses a cold nature; the coldness is sufficient to restrain Fire, thereby allowing the flaccidity to heal spontaneously. "Exhaustion and injury" refers to the depletion of Yin fluids and damage to essence. The cold nature benefits Water, while the acrid flavor provides moistening; moistening leads to the fullness of Yin essence. The "penis" (Jing) suffers pain due to Fire stagnating internally. Heat is cleared with cold substances, and stagnation is dispersed with acrid substances; thus, it treats pain in the penis. Urine is excreted through Qi transformation. As an acrid-cold substance, it clears and purifies Lung Qi, thereby promoting urination. The Lung governs Qi, and the Kidney regulates Qi. Cold benefits the Kidney, and acrid moistens the Lung; therefore, it supplements Qi and strength. Once Qi and strength are supplemented, they nourish the internal upright and vigorous energy, thereby stabilizing the will, as the Kidney stores the Will (Zhi).
Preparations:
Epimedium soaked in wine treats hemiplegia (Pian Feng). For lower back pain caused by fluid depletion, it is combined with Schisandra Berry (Wuwei Zi) and Raspberry (Fupenzi) in pill form to treat cough involving the Triple Burner. Ground into fine powder and used for rinsing, it treats toothache.
[Morinda Officinalis]
The nature is slightly warm. The flavor is acrid and sweet. It is non-toxic. It primarily treats severe pathogenic wind (Da Feng), impotence with inability to erect, strengthens sinews and bones, calms the Five Zang organs, tonifies the Middle Jiao, enhances the will, and supplements Qi. (Baked with wine)
Morinda Officinalis has a slightly warm nature, inheriting the rising Wood Qi of spring from heaven, entering the Foot-Jueyin Liver Meridian. Its acrid-sweet flavor and non-toxicity derive from the Metal and Earth flavors of earth, entering the Foot-Yangming Dry-Metal Stomach Meridian. Both its aroma and flavor ascend, making it Yang in nature. Wind Qi communicates with the Liver. Morinda enters the Liver meridian; its acrid and sweet properties disperse, treating severe pathogenic wind by dispersing and draining it. Yin corresponds to the Zongjin. The Zongjin belongs to the Liver. Flaccidity with inability to erect indicates that the Liver has completely lost its motivating Yang. Morinda's warm nature supplements Yang, thus treating this condition. Generally, Morinda treats impotence due to Yang deficiency, whereas Epimedium treats impotence due to Yin deficiency. The Liver governs sinews, and the Kidney governs bones. Acrid-warm properties benefit the Liver and Kidney, thus strengthening sinews and bones. The Stomach is the source of the Five Zang organs and the head of the Twelve Meridians. Acrid-sweet flavors enter the Stomach, and warmth assists Stomach Yang, thereby calming all Five Zang organs. The Stomach represents Central Earth; when Earth is warm, the Middle Jiao is naturally tonified. The Kidney regulates Qi and stores the Will. Morinda's warm nature benefits Liver Qi. The Liver is associated with courage (Gan). If Liver Qi is not deficient, it does not deplete Kidney Qi, thereby increasing the Will and Qi.
Preparations:
Morinda Officinalis combined with Schisandra Berry, Cistanche, Cornus Fruit, Deer Antler, Biota Seed, Goji Berry, and Psoralea Fruit treats impotence. Combined with Deer Horn, Biota Seed, Ophiopogon Root, Polygala Root, Lotus Stamen, Raspberry, and Phellodendron Bark, it treats nocturnal emissions and seminal leakage associated with dreams of sexual intercourse with spirits. Combined with Prepared Rhubarb, it treats foot conditions in individuals who consume alcohol.
