**Shengjiang (Fresh Ginger, *Zingiberis Rhizoma Recens*)**, grows in the valleys of Jianwei as well as Jingzhou and Yangzhou; it is now available everywhere, with those from Hanzhou, Wenzhou, and Chizhou being considered superior. The plant is two to three chi high; the leaves resemble bamboo leaves of the arrow type but are longer, growing in opposite pairs; the stems and leaves are green; the rhizome is yellow; it does not flower or bear fruit. In autumn, the rhizomes are harvested, washed in flowing water, sun-dried to produce **Ganjiang (Dried Ginger, *Zingiberis Rhizoma*)**. The method for making Ganjiang in Hanzhou: soak the ginger in water for three days, peel it, then place it in flowing water for another six days, scrape off the skin again, sun-dry it thoroughly, and finally ferment it in a jar for three days until complete. Recent medical formularies record a prescription for treating deficiency-cold of the Spleen and Stomach, inability to eat, and chronic emaciation leading to consumptive disease (**Xiezhai, Consumptive Disease**), using a single ingredient: white dried ginger from Wenzhou. Boil it in sour rice wash until moist throughout, take out, bake dry, pound and sieve. Mix with congee made from aged grain warehouse rice to form pills the size of **Wuzi (Cocculus seeds)**. Take 30-50 pills per dose, with decoction as needed; the effect is miraculous. Additionally, *Qianjin Fang* treats phlegm-rheum (**Tan Yin**) with **Jiangfu Tang (Ginger and Aconite Decoction)**. Take eight liang of Shengjiang and four liang of raw Fuzi, split in the middle. Add five sheng of water to these two ingredients, boil down to two sheng, and divide into two doses. This formula also treats sudden wind-stroke (**Cu Feng**). Avoid pork and cold water during treatment. Cui Yuanliang's *Jiyan Fang* records an imperial gift recipe for ginger tea to treat dysentery (**Li Ji**): cut fresh ginger into sesame-sized pieces, mix with one or two bowls of good tea, sip at will, and recovery follows. For heat-type dysentery, retain the ginger skin; for cold-type dysentery, removing the skin is highly effective. Liu Yuxi's *Chuanxin Fang*, attributed to Li Ya, treats all types of cough and upward rushing of Qi (**Shangqi**) using Ganjiang, specifically requiring top-quality product from Hezhou. Processed Zaojiao (Gleditsia sinensis), peeled and seeded, selecting plump ones without holes; Guixin (Cinnamon twig heart), purple and pungent, peeled. Combine these three, pound separately, sieve, then mix in equal parts according to need, pound and sieve again. Knead with refined white honey, pounding 1,000-2,000 times more. Take three pills per dose, slightly larger than cocculus seeds, regardless of meal timing. Take when cough starts, 3-5 times daily. Avoid scallions, oil, salty foods, fishy/meaty foods, and hot-natured noodles; the effect is miraculous. Liu Yuxi served in Huainan alongside Li Qing. Li often dispensed medicine without providing the prescription, leading others to mock his stinginess. Li privately explained: "Most people suffering from cough take cold-natured medicines. If they see this prescription uses hot and drying herbs, they refuse to take it. Thus, I only provide the herbs, and the efficacy is high." Trials confirmed this truth. Li Qing's formula for reversing white hair: Scrape one da-sheng of old ginger skin. Simmer in a pot over alternating mild and strong fire, ensuring it does not boil vigorously. The pot should ideally be one previously used for oily foods, preferably uncleaned. Place the ginger skin in the pot, seal tightly to prevent gas leakage. Assign a meticulous person to watch; start simmering slowly before dawn, avoiding intense fire. If the watcher becomes tired, rotate personnel. Complete within one shichen (two hours). Store in a porcelain bowl and grind extremely fine. Li stated: "Although it says one shichen, if the fire is even, the medicine is ready by sunset." To use, dip a small object to take a amount the size of a hemp seed. Apply under white beard hairs first, then pluck the white hair. Upon replucking, rub gently with fingers to let the medicine penetrate the flesh. On the fourth day, black hairs should grow; this is miraculous.
