Fukitsushi (Fructus Kochiae), bitter in flavor and cold in nature, is non-toxic. It enters the Spleen Meridian.
Fukitsushi specializes in promoting water passages, clearing heat from the Bladder, and bathing the body can relieve skin pruritus, heat rashes; washing the eyes removes ocular heat, night blindness (Que Mang), and astringent pain.
Main indications (referencing *Dou Zhen He Can*): Primarily treats Bladder heat, promotes urination, clears heat from the skin, and additionally resolves toxin of smallpox.
Note: Fukitsushi has a bitter and cold aroma, deriving its qi transformation from the Taiyang Cold Water. The Qi of Taiyang reaches up to the highest heavens and penetrates down to the deepest springs, spreading externally over the skin and muscles. Therefore, it can treat the head above, benefiting hearing and vision; enter the Bladder below, promoting diuresis and treating hernia; and expel heat from the skin externally, making the skin moist and lustrous.
Xuduan (Radix Dipsaci), endowed with the Qi of Metal and inheriting the Yang Qi of Heaven for its generation, tastes bitter, sweet, and acrid, is slightly warm, and non-toxic. For formulas treating uterine bleeding (Ben Beng) and metallic wounds, raw use is appropriate. When combined with Shudi (Prepared Rehmannia Root) for tonification, wine-fried use is appropriate.
Xuduan aids Shudi in continuing tendons and bones, primarily treating internal injury and insufficiency, regulating blood vessels, and specifically treating falls and fractures. It reduces swelling and detoxifies, generates flesh, and excels in managing metallic wounds and carbuncles, relieving pain and generating tissue. It shows remarkable efficacy for breast abscesses (Ru Yong) and scrofula (Luo Li), and immediate effect for intestinal wind and hemorrhoids/fistulas (Chang Feng Zhi Lou); it reduces frequent urination, secures essence and stops nocturnal emission, warms the uterus, stabilizes pregnancy, and long-term use increases physical strength. It is an essential medicine for miscarriage, metrorrhagia, and leukorrhea during pregnancy and childbirth, as well as for supplementing exhaustion and healing injuries. It addresses symptoms such as heavy body, lower back pain, joint laxity or stiffness, and various injuries to the Blood aspect.
Main indications (referencing *Dou Zhen He Can*): Efficacy is the same as above. The best quality consists of segments that are broken, with yellowish wrinkled skin, producing dust-like smoke when snapped. It should be soaked in wine and dried before use. It enters the Jueyin Liver Meridian to nourish the Liver, the Shaoyin Kidney Meridian to warm the Kidney, and the Taiyin Spleen Meridian to nourish Blood. It nourishes and invigorates Blood while simultaneously yin-nourishing and qi-tonifying. It tonifies without causing stagnation and moves without causing leakage. Bitterness strengthens the Kidney, acridity opens the Kidney, and warmth moves stagnation. It is indeed a crucial herb assisting in the tonification of Qi and Blood.
Roudoukou (Nux Vomica Seed / Nutmeg - *Note: Context implies Myristica fragrans based on description, though classical texts sometimes conflate or specify distinct varieties. Standard translation uses Nutmeg for Roudoukou*). Endowed with the Qi of Fire, Earth, and Metal, it tastes acrid, is warm in nature, and non-toxic. It enters the Foot-Taiyin Spleen Meridian and Foot-Yangming Stomach Meridian, and also the Hand-Yangming Large Intestine Meridian. Acridity disperses and eliminates, warmth harmonizes the middle and unblocks circulation. Its fragrance first enters the Spleen, and its warmth opens the appetite. Thus, it is a key medicine for regulating the Spleen, opening the stomach, digesting food, and stopping diarrhea. If there is damp-heat accumulation, especially during the initial stage of dysentery (Zhi Xia) or acute hot diarrhea (Bao Zhu Xie Xie), it is contraindicated. It should be wrapped in flour, baked (wei), pounded, and the oil removed before use.
Roudoukou warms deficiency-cold of the Spleen and Stomach, treats abdominal distension and pain due to retained food, slippery diarrhea, and cold dysentery, making it particularly important. The nature of Earth favors warmth and fragrance, so Roudoukou is most suitable for the Spleen and Stomach.
Main indications (referencing *Dou Zhen He Can*): It is a key medicine for treating smallpox complicated by Spleen cold, leading to diarrhea, vomiting, teeth chattering, and shivering. It warms the middle, opens the stomach, digests food, and directs Qi downward. The term "directing Qi downward" refers to the fact that when the Spleen is supplemented, it functions well in transportation and transformation, and Qi naturally descends. However, it should not be taken early in cases of initial diarrhea/dysentery or in patients with excess fire.
