【秦艽】
气性平。味苦。无毒。主治寒热邪气、寒湿风痹、肢体关节疼痛、腹泻及小便不利。（处理方法：用酒浸泡后晒干）
秦艽气性平，禀受自然界秋季下降的金气，归入手太阴肺经。味苦且无毒，得自大地南方的火味，归入手少阴心经。
其气味俱降，属阴。皮毛归属于肺，外感邪气从皮毛侵入人体，或为寒邪或为热邪，一旦感受，肺脏首先受邪。秦艽入肺经，味苦能泄降，所以主治此类病症。风寒湿三者结合形成痹证，痹证则导致血液运行涩滞不畅。味苦入心，心生血，苦味能散结，血液运行通畅则痹证自愈。肢体关节疼痛，是湿气流注关节所致。秦艽气性平而降肺气，肺气宣行则水道通利，水道通利则湿气下排。其治疗腹泻和小便不利的功效，都是通利水道的功劳。以左侧生长的为佳。
制方用法：
秦艽用酒煎煮，治疗黄疸。
单用一两，治疗小便困难、腹部胀满。
与柴胡、甘草同用，治疗急劳烦热。
与干葛（葛根）、茵陈、五味子、川莲（黄连）、扁豆、木通、薏苡仁同用，治疗酒疸。
与薏苡仁、木瓜、五加皮、黄柏、苍术、牛膝同用，治疗下部湿热引起的疼痛以及湿疮。
【石斛】
气性平。味甘。无毒。主治内伤、去除痹证、降气、补益五脏虚劳导致的身体消瘦羸弱、强健阴精、增益精气。长期服用可使肠胃厚实。（处理方法：用酒浸泡后晒干）
石斛气性平，禀受自然界秋季下降的金气，归入手太阴肺经。味甘且无毒，得自大地中正的土味，归入足太阴脾经。
甘平是金和土的气味特征，归入足阳明胃经和手阳明大肠经。气降味和，属阴。阴是体内的守持者。阴虚则导致内伤，甘平之性益阴，所以主治内伤。痹就是闭塞的意思。血液枯竭而涩滞，就会出现麻木和痹证。甘平之性益血，所以又能去除痹证。肺主气，肺热则气机上逆，气性平能清肺，所以能降气。五脏贮藏阴精，阴虚则五脏都虚弱，不能胜任劳作。劳作则会进一步损伤真气。五脏之阴，以脾为源头。脾主肌肉，所以五脏虚劳会导致肌肉消瘦。甘平之性益阴，所以主治虚劳并促进肌肉生长。阴指宗筋，是太阴和阳明经脉交会之处。石斛味甘能补益脾胃，所以能强健阴精。精是阴气的精华。甘平之性滋阴，所以能增益精气。肠指手阳明大肠，胃指足阳明胃。手足阳明经属于燥金，燥则肠胃薄弱。长期服用甘平清润之物，则阳明经不燥，肠胃变得厚实。
制方用法：
石斛与麦冬、五味子、人参、白芍、甘草、枸杞子、牛膝、杜仲同用，调理内伤，补益虚劳，强健阴精。
与麦冬、白茯苓、陈皮、甘草同用，治疗胃热导致的四肢软弱无力。
单用一味，夏季代茶饮用，增强脚力。
[Qin Jiao]
Nature is neutral (Ping). Flavor is bitter. Non-toxic. Mainly treats cold-heat pathogenic factors, wind-damp-bi syndrome caused by cold-dampness, pain in limbs and joints, diarrhea, and difficult urination. (Processing method: Soak in wine and dry.)
Qin Jiao has a neutral nature, inheriting the metal energy of autumn that descends from heaven, entering the Hand-Taiyin Lung Meridian. Its flavor is bitter and non-toxic, obtaining the fire flavor of the south from earth, entering the Hand-Shaoyin Heart Meridian.
Both its nature and flavor descend, belonging to Yin. The skin and hair belong to the Lung. Pathogenic factors from external contraction enter through the skin and hair; whether cold or heat, upon infection, the Lung is first affected. Qin Jiao enters the Lung, and its bitter flavor can drain and descend, thus treating these conditions. Wind, cold, and dampness combine to form Bi syndrome (obstruction), causing blood stasis and poor circulation. Bitter flavor enters the Heart, which generates blood; bitterness can dissipate nodules, so when blood circulation flows smoothly, Bi syndrome heals itself. Pain in limbs and joints is due to dampness flowing into the joints. Qin Jiao's neutral nature descends Lung Qi; when Lung Qi moves, the water passages become unobstructed, and when water passages are clear, dampness is expelled downward. Its effects in treating diarrhea and facilitating urination are all due to the function of unblocking water passages. Those growing on the left side are superior.
Prescription Methods:
Qin Jiao decocted in wine treats Jaundice (Huang Dan).
Used alone at 1 liang, it treats difficult urination with abdominal fullness.
Combined with Chai Hu (Bupleuri Radix) and Gan Cao (Glycyrrhizae Radix), it treats acute consumptive fever with irritability.
Combined with Ge Gen (Puerariae Lobatae Radix), Yin Chen (Artemisiae Scopariae Herba), Wu Wei Zi (Schisandrae Fructus), Chuan Lian (Coptidis Rhizoma), Bian Dou (Dolichoris Semen), Mu Tong (Akebiae Caulis), and Yi Yi Ren (Coicis Semen), it treats Wine Jaundice (Jiu Dan).
Combined with Yi Yi Ren, Mu Gua (Chaenomelis Fructus), Wu Jia Pi (Acanthopanacis Cortex), Huang Bo (Phellodendri Cortex), Cang Zhu (Atractylodis Rhizoma), and Niu Xi (Achyranthis Bidentatae Radix), it treats pain caused by damp-heat in the lower body and damp sores.
[Shi Hu]
Nature is neutral. Flavor is sweet. Non-toxic. Mainly treats internal injury, removes Bi syndrome, directs Qi downward, tonifies deficiency-wasting syndrome of the five Zang organs leading to emaciation, strengthens Yin, benefits essence, and thickens intestines and stomach with long-term use. (Processing method: Soak in wine and dry.)
Shi Hu has a neutral nature, inheriting the metal energy of autumn that descends from heaven, entering the Hand-Taiyin Lung Meridian. Its flavor is sweet and non-toxic, obtaining the central earth flavor from earth, entering the Foot-Taiyin Spleen Meridian.
Sweet and neutral are the flavors of Metal and Earth, entering the Foot-Yangming Stomach Meridian and Hand-Yangming Large Intestine Meridian. Nature descends and flavor is harmonious, belonging to Yin. Yin is the guardian within. Yin deficiency leads to internal injury; sweet and neutral properties benefit Yin, thus treating internal injury. Bi means obstruction. When blood is depleted and stagnant, numbness and Bi occur. Sweet and neutral properties nourish blood, thus removing Bi. The Lung governs Qi; Lung heat causes Qi to rebel upward. Neutral nature clears the Lung, thus directing Qi downward. The Five Zang organs store Yin. Yin deficiency leads to weakness of all Five Zang organs, making them unable to withstand labor. Labor further damages True Qi. Among the Yin of the Five Zang organs, the Spleen is the source. The Spleen governs muscles; therefore, deficiency-wasting of the Five Zang organs leads to muscle emaciation. Sweet and neutral properties benefit Yin, thus treating deficiency-wasting and generating muscle tissue. Yin refers to the sinews, where Taiyin and Yangming meridians converge. Shi Hu's sweet flavor benefits the Spleen and Stomach, thus strengthening Yin. Essence is the brilliance of Yin Qi. Sweet and neutral properties nourish Yin, thus benefiting essence. Intestines refer to the Hand-Yangming Large Intestine; Stomach refers to the Foot-Yangming Stomach. Hand and Foot Yangming meridians belong to Dry Metal; dryness makes the intestines and stomach thin. Long-term use of sweet, neutral, clearing, and moistening substances prevents Yangming dryness, thereby thickening the intestines and stomach.
Prescription Methods:
Shi Hu combined with Mai Dong (Ophiopogonis Radix), Wu Wei Zi, Ren Shen (Ginseng Radix et Rhizoma), Bai Shao (Paeoniae Radix Alba), Gan Cao, Qi Zi (Lycii Fructus), Niu Xi, and Du Zhong (Eucommiae Cortex) regulates internal injury, tonifies deficiency-wasting, strengthens Yin, and benefits essence.
Combined with Mai Dong, Bai Fu Ling (Poria), Chen Pi (Citri Reticulatae Pericarpium), and Gan Cao, it treats weak and flaccid limbs due to Stomach heat.
Used alone as tea during summer months, it strengthens leg power.
