[Shichangpu / Acori Tatarinowii Rhizoma]
Promotes circulation, opens orifices.
Pungent and bitter in flavor, warm in nature. Aromatic and dispersing. Opens the heart orifice, benefits the nine orifices of the body, clarifies the ears and eyes, facilitates voice production. Expels dampness and dispels wind, drives out phlegm and eliminates accumulation, opens the stomach and broadens the middle jiao. Treats jin kou du li (toxic dysentery with inability to eat). (Yang Shiying stated: Although jin kou li belongs to Spleen deficiency, it is also caused by heat closing the chest and diaphragm. Using Xiang Mu (Aucklandiae Radix) is too warming; using Shan Yao (Dioscoreae Rhizoma) is too astringent/closing. Only Shen Ling Bai Zhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) added with Shichangpu, taken with rice water, can open the chest region, after which appetite naturally returns.) Treats feng bi (wind-bi syndrome). (Fermented with Shu Mi (Panicum miliaceum), treats various wind diseases.) Treats jing xian (startle epilepsy), beng dai (metrorrhagia and leukorrhea), tai lou (fetal leakage). Reduces swelling and relieves pain, detoxifies and kills parasites. (Li Shicai stated: Daoist classics call it the essence of aquatic plants and the spiritual medicine of immortals. Soaked in rice water and steamed over rice, borrowing the qi of grain to achieve a neutral state, it truly has extraordinary effects. He further said: Its aromatic nature benefits the orifices; it is a fine medicine for the Heart and Spleen. It can assist herbs such as Dihuang (Rehmanniae Radix) and Tiandong (Asparagi Radix), aiding their guiding and promoting functions. However, if used alone in large doses, it may consume Qi and Blood and cause harm.) Fragrant, drying, and dispersing. Contraindicated in cases of Yin and Blood deficiency. Especially forbidden in cases of seminal emission/slippery discharge and excessive sweating. Grows among aquatic stones, not touching soil. The rhizome is slender with dense nodes; those with nine nodes per cun are considered superior. Remove hairs, stir-fry slightly. Qin Jiao (Gentianae Macrophyllae Radix) serves as its guiding herb. Adversely affected by iron vessels. (Contact with iron vessels causes vomiting and rebellion.)
[Puhuang / Typhae Pollen]
Raw use: promotes smooth flow and moves blood; Stir-fried until blackened: astringent to stop bleeding.
Sweet in flavor, neutral in nature. Enters the Jueyin Blood level. (Corresponds to Pericardium and Liver meridians.) Raw use has a slippery nature, moves blood and resolves stasis, unblocks meridians, promotes urination, and clears heat from the Heart, abdomen, and Bladder. (When combined with Wulingzhi (Trogopterori Faeces), it is named Shixiao San (Laughing Dispersal Powder), treating pain due to Qi and Blood stagnation in the Heart and abdomen.) Treats traumatic injuries from falls and blows, sores, boils, and various swellings. (A woman had a tongue swollen enough to fill her mouth; frequent application of Puhuang powder cured her by dawn. Emperor Duzong of Song had a tongue swollen to fill his mouth; the imperial physician applied an equal mixture of Puhuang and Ganjiang (Zingiberis Rhizoma) powder, which also cured him. Li Shizhen stated: Observing these cases, one can understand that Puhuang cools blood and invigorates blood. Since the tongue is the sprout of the Heart, and the Ministerial Fire of the Pericardium acts as its attendant, the addition of Ganjiang represents the mutual assistance of Yin and Yang.) When stir-fried until blackened, its nature becomes astringent, stopping all types of bleeding. Treats metrorrhagia, leukorrhea, and spermatorrhea. Do not take if there is no blood stasis. Puhuang is the dust from the stamens of the catkin of Typha orientalis. Add to the decoction when the medicine is ready. (For recurrent sores on the tongue, apply Puhuang powder topically to cure; for ear bleeding, stir-fry Puhuang until blackened, grind into powder, and apply locally for efficacy.)
