1、对泌尿系统的作用：猫须草（肾茶）液拌饲给予大鼠，增加肾脏重量，降低尿素氮和血肌酐，促进肾脏排泄。肾茶水提液灌胃，对小鼠有利尿作用；十二指肠给药，增加家兔输尿管动作电位的频率与幅度。肾茶水提物口服对正常大鼠有利尿作用，但对尿液pH无影响。肾茶煎剂抑制血清或脂多糖刺激的原代培养的大鼠肾小球系膜细胞增殖，抑制脂多糖诱导的系膜细胞分泌IL-1β。肾茶水提液灌胃对慢性肾功能衰竭大鼠能降低血清尿素氮、中分子物质和肌酐，改善贫血症状，增加内生肌酐清除率及尿肌酐的排泄；减轻肾小管组织细胞病变，减少肾小球结构破坏，增加完整肾小球数目。2、其他作用：肾茶水提液灌胃，缩短小鼠断尾法出血时间。肾茶水提物口服抑制小鼠巴豆油所致的耳肿胀；水提物体外对金黄色葡萄球菌、大肠杆菌和铜绿假单胞菌有抑制作用。低、中剂量肾茶提取液灌胃增强小鼠腹腔巨噬细胞吞噬功能、ConA诱导的脾淋巴细胞增殖反应及NK细胞活性，增加溶血空斑形成细胞（PFC）数目。但高剂量肾茶却无此作用。肾茶对脾脏指数胸腺指数无影响。猫须草中的高山黄芩素四甲醚等在体外试验中对艾氏腹水癌细胞生长有剂量依赖性抑制作用。相关论述

1. Effects on the urinary system: When given to rats, a solution of cat's whiskers (kidney tea) increased kidney weight, reduced blood urea nitrogen and creatinine levels, and promoted kidney excretion. When administered to mice, a solution of kidney tea had a diuretic effect. When given to rabbits in the duodenum, it increased the frequency and magnitude of ureteral peristalsis. Oral administration of kidney tea extract to normal rats had a diuretic effect but did not affect urine pH. A decoction of kidney tea inhibited the proliferation of mesangial cells in rat kidney glomeruli in primary cultures stimulated by serum or lipopolysaccharide, and suppressed lipopolysaccharide-induced secretion of IL-1β by mesangial cells. Gastric administration of kidney tea extract reduced serum urea nitrogen, middle molecule substances, and creatinine in rats with chronic renal failure, improved anemia symptoms, increased endogenous creatinine clearance rate and urinary creatinine excretion, alleviated renal tubular cell lesions, reduced renal glomerular structural damage, and increased the number of intact glomeruli.2. Other effects: Gastric administration of kidney tea extract shortened bleeding time in mice subjected to tail amputation. Oral administration of kidney tea extract inhibited ear swelling in mice induced by croton oil. In vitro, the aqueous extract of kidney tea had inhibitory effects on Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Low and medium doses of kidney tea extract enhanced the phagocytic function of peritoneal macrophages in mice, ConA-induced splenic lymphocyte proliferation response, and NK cell activity, and increased the number of plaque-forming cells (PFC). However, high doses of kidney tea did not have these effects. Kidney tea had no effect on spleen index or thymus index. Compounds such as baicalin tetramethyl ether in cat's whiskers showed dose-dependent inhibitory effects on the growth of Ehrlich ascites carcinoma cells in in vitro experiments.

Distributed in Fujian, Guangxi, Hainan, Yunnan, Taiwan, and other regions. Growing environment.

生于海拔700-1000m的林下潮湿处或草地上，更多的为栽培。生长见习
It grows in damp areas under the forest canopy or on grasslands at an altitude of 700-1000 meters, mostly cultivated. It is commonly found in practice.

喜高温多湿环境，怕寒，怕旱，忌积水，耐肥。年平均气温18-24℃的地区，生长正常，平均气温25-30℃的高温多雨月份生长迅速旺盛，月平均气温17℃以下时生长停止，气温低于4℃时，叶红、枯萎、死亡。宜选土层深厚、富含有机质的砂壤或壤土，且具有适当荫蔽的环境栽培为好。繁殖方式
Prefers hot and humid environments, dislikes cold and drought, avoids stagnant water, and is tolerant to fertilizers. It grows normally in areas with an average annual temperature of 18-24°C. It grows rapidly and vigorously in months with high temperatures and heavy rainfall, with an average temperature of 25-30°C. Growth stops when the monthly average temperature drops below 17°C, and the leaves turn red, wither, and die when the temperature falls below 4°C. It is best cultivated in deep, organic-rich sandy loam or loam soil with appropriate shading. Reproduction methods.

多用扦插繁殖或分株繁残。栽培技术
Propagation is often done through cutting or division. Cultivation techniques.

扦插繁残：适宜的扦插时间，北方7-8月；南方四季均可，以3-4月份为好。插条长10cm，每截段保留2-3节，插穗宜随剪随插，行距15-20cm，株距5-7cm，插后保持荫蔽，湿润，约2星期内生根，存活后15d左右可移栽，行株距30cm左右为宜。分株繁殖：在生长旺季到来之前时行，分株取苗（包括下垂触地生根的老枝）直接移栽。田间管理移栽后注意保湿，生长期适时除草、松土和追肥，肥料以腐熟厩肥或人畜粪尿等有机肥为好。
Cutting propagation: Suitable cutting time is from July to August in the northern regions; in the southern regions, it can be done throughout the year, with March to April being the best. Cuttings should be about 10cm long, with 2-3 nodes on each section. Cuttings should be inserted immediately after cutting, with a spacing of 15-20cm between rows and 5-7cm between plants. After planting, keep the cuttings shaded and moist. Roots should develop within about 2 weeks, and after about 15 days of survival, the cuttings can be transplanted, with a plant spacing of around 30cm being ideal. Division propagation: This should be done before the peak growing season. Take the shoots directly for transplantation, including the old branches that have rooted on the ground. After transplanting, pay attention to keeping the soil moist. During the growing season, timely weeding, loosening the soil, and applying organic fertilizers such as well-rotted stable manure or animal and human manure are recommended.
