It is Xiheliu (Tamarix Chinensis).
Sweet, salty, warm. Enters the Foot-Yangming Stomach Channel and Hand-Taiyin Lung Channel. Resolves the restlessness and confusion caused by Warm Epidemic (acute febrile diseases caused by warm pathogenic factors), opens up the evil accumulation in muscles. For all wind-fire severe pathogens (pathogenic factors with strong infectivity and toxicity), this herb is indispensable for reaching the exterior.
Sweet, neutral. Slippery and lubricating. Enters the Hand-Taiyin Small Intestine Channel and Foot-Taiyang Bladder Channel. Benefits various orifices, unblocks urination and defecation, and guides downward to expel tangible stagnant matter from the body. Treats stranguria swelling, wheezing and cough, insomnia. (Sleep occurs when fire qi descends.) Paired with Danggui Shen (Radix Angelicae Sinensis Root), treats post-abortion bleeding. (Bleeding stops when fire clears.) Mixed with egg white, treats Wuse Dandu (Five-Color Dan Du, an acute infectious skin disease characterized by rapid onset, changing colors, redness, swelling, heat, and pain).
Consuming soup made from young seed pods promotes sleep. Contraindicated in cases of Spleen-Stomach Qi deficiency and cold.
Pungent, bitter, warm. Enters the Qi level of the Hand-Taiyin Lung Channel and Foot-Taiyin Spleen Channel. Eliminates evil pathogens in the skin and joints, manifesting as itching like insects crawling on the skin. Dispels wind-dampness in the five viscera, stops cold slipperiness of the Large Intestine (loose stools due to cold-dampness), kills parasites, aids digestion, and is essential for treating such conditions. (Parasites arise from dampness; food stagnation arises from cold.) Combined with Binglang (Areca Seed), it kills various parasites. Paired with Ganxi (Dried Lac Insect), treats Chongxian (epileptic seizures caused by parasites). Paired with Hezi (Chebula Fruit) and Doukou (Black Cardamom), treats Xiao'er Ganxie Lengli (pediatric malnutrition with diarrhea and cold dysentery). Paired with Chuanlian (Rhizoma Coptidis), treats Gyanre Shengchong (parasitic infection arising from malnutrition heat). (Adding Zhu Danzhi (Pig Gallbladder Bile) and Shexiang (Musk) enhances efficacy.) Paired with Chuanlian powder, formed into pills with Zhu Danzhi, treats Jingyin (sudden aphonia due to wind-heat). (As wind-heat dissipates.) Paired with herbs that warm the stomach, benefit blood, and regulate the middle (such as Lizhong Wan), treats Bie Xia (abdominal mass resembling a turtle, varying in size, invading the throat upwards and eroding the anus downwards). As the chief ingredient with Zhuzhi (Pig Fat), applied topically for hot sores. Mixed with honey, applied for wet tinea.
Shells removed, stir-fried. To kill parasites, stir-fry with flour. Contraindicated in cases of Spleen-Lung dryness-heat.
Sweet, pungent, salty. Enters the Blood level of the Foot-Sanyin Liver, Spleen, and Kidney Channels. Reaches the Lower Jiao, drains the large intestine, breaks down dead blood (blood stasis), disperses carbuncles and swellings, expels pus, and relieves pain. Combined with Renshen (Ginseng Root), treats postpartum asthma/wheezing. Paired with Rushiangu (Resina Burserae), treats Xuefeng Koujin (facial paralysis or trismus due to blood deficiency and wind invasion). Guided by Fangfeng (Saposhnikovia Root), releases wind-pathogens from both interior and exterior. Crushed, decocted strongly in wine, and added to medicine, treats pain caused by blood stasis from falls and blows.
Small doses harmonize blood; large doses break blood. Do not administer indiscriminately to patients with blood deficiency and internal pain.
Bitter, astringent, neutral. Treats dysentery, intestinal wind (intestinal bleeding), stops metrorrhagia and leukorrhea. Combined with Fa Tan (Carbonized Human Hair), treats hematemesis and epistaxis. Paired with Wuzeigu (Cuttlefish Bone), treats Xuelin (hematuria with painful urination). Mixed with Kufan (Alumen Calcined), treats Xue Beng (profuse uterine bleeding). Mixed with honey and tea, treats intestinal bleeding. (Combined with Gualou Tan (Carbonized Trichosanthes Fruit) is also effective.) Combined with Ce Bai Tan (Carbonized Biota Tops) and Juan Bai Tan (Carbonized Selaginella), formed into pills with rice paste, stops chronic lower bleeding that persists for years.
Shoots, flowers, and seeds are all usable; all should be carbonized and taken mixed with water, not decocted in soup. Contraindicated at the initial stage of dysentery.
