This article discusses the syndrome differentiation and treatment of stress urinary incontinence from the perspectives of the lungs, kidneys, and heart. It is suggested that the initial stage of the disease is marked by the dysfunction of the lung and the disorder of qi movement, while the intermediate stage is characterized by the obstruction of qi movement and the instability of the kidney, and the advanced stage is characterized by the depletion of the kidney and the disturbance of the spirit. According to the characteristics of the disease and the changes in the pathogenesis, the methods are recommended including regulating the lung, boosting qi and governing water, nourishing the kidney and enriching essence, and calming the mind and soothing the spirit. Accordingly, self-designed prescriptions such as Shenqi Lifei Decoction(参芪利肺汤), Yiqi Gupao Decoction(益气固脬汤), and Yishen Shenning Decoction(益肾神宁汤)with modifications can be used to regulate the lungs, adjust the kidneys, and calm the mind, thereby achieving the treatment of stress urinary incontinence from the perspectives of the lungs, kidneys, and heart.

This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material, covering aspects such as nomenclature, origin, geographical distribution, harvesting and processing methods, quality assessment, therapeutic effects and indications, by consulting ancient herbal texts, medical compendia, and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty, with Zhuli being the standard name used throughout history, alongside aliases like Zhuzhi, Zhuyou and Huoquan. Historically, the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis(Danzhu), although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou(present-day Chengdu and surrounding areas in Sichuan) and the Wuling region(between present-day Hunan, Guangdong, Guangxi and Jiangxi provinces), while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally, Bambusae Succus was harvested from bamboo that had grown for exactly one year, today, it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation, whereas modern industrial production employs dry distillation, reflux extraction, and percolation. In terms of quality evaluation, ancient texts considered a sweet taste to be superior, while today, clarity and transparency are prioritized. Historically, Bambusae Succus was characterized as sweet and cold nature, targeting the lung and stomach meridians, with uses evolving from clearing heat and resolving phlegm to nourishing Yin, moistening dryness, and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet, bitter, and cold in nature, affecting the heart, liver, and lung meridians, with functions including clearing heat, resolving phlegm, and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion, lung heat with phlegm congestion, convulsions, epilepsy, excessive phlegm in febrile diseases, high fever with thirst, irritability during pregnancy, and tetanus, with more clearly defined applications. Based on the results of the research, it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus, the one-year-old Phyllostachys nigra var. Henonis, which has been highly praised throughout history, should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore, in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste, and reasonable modern quality control standards should be established.

By consulting ancient and modern literature, this article systematically reviews and verifies the historical evolution of the herbal medicine known as Baijiang across various dimensions, including name, origin, scientific name verification, medicinal parts, production area, quality, harvesting and processing, as well as its nature, taste, and therapeutic effects, in order to provide a reference for the development and utilization of famous classical formulas containing Patriniae Herba. Patriniae Herba has a long history of use. It derives its name from the distinctive musty odor of its roots, which resembles spoiled soy sauce. However, due to its alias Kucai, there has been much confusion with other plants. Since the Ming dynasty, various plants have been used interchangeably as Baijiang. Herbal textual research showed that Patriniae Herba was first recorded in Shennong Bencaojing, and throughout history, Baijiang has been recognized as its standard name, though it has also been known by alternative names such as Luchang, Lujiang, and Suanyi. The main sources used throughout the ages were Patrinia scabiosaefolia or P. villosa, which is consistent with the 1977 edition of the Pharmacopoeia of the People's Republic of China. However, while the roots were traditionally used medicinally, the whole plant is now more commonly used in modern practice. In addition, the whole plants of Thlaspi arvense from the Cruciferae family and Sonchus brachyotus from the Compositae family are commonly used as regional substitutes for Baijiang. According to ancient records, Patriniae Herba was primarily found in Jiangxia(present-day eastern Hubei province) and Jiangdong(the region south of the lower reaches of the Yangtze River), but modern literature shows that it is distributed throughout the country without a distinct geographical origin. In ancient times, the roots were harvested in August and sun-dried, today, the whole plant is typically dug up in summer or autumn and sun-dried. In recent times, the quality has been summarized as being best when the roots are long, the leaves are abundant and green, and the aroma is strong. Regarding the processing, ancient methods often involved baking(drying over fire), while modern methods typically involve removing impurities, washing, and then cutting and drying the segments. The effects of Patriniae Herba are to clear heat and detoxify, eliminate blood stasis and drain pus. During the Han and Northern and Southern dynasties, it was used to treat skin diseases caused by heat, abscesses, postpartum diseases, and rheumatism, during the Five dynasties period, its therapeutic applications expanded to include diseases of the five senses, and by the modern era, conditions such as neurasthenia and insomnia were added. Regarding its properties and taste, it was recorded as bitter and neutral during the Han dynasty. By the Tang dynasty, it was slightly cold, with a taste of acrid and bitter. During the Yuan and Ming dynasties, it was mostly slightly cold and neutral, with a bitter and salty taste. In the Qing dynasty and modern times, it was mostly bitter and neutral, and in contemporary times, it has evolved to a taste of acrid, bitter, and cool. Based on the results of this study, it is recommended that when developing and utilizing famous classical formulas containing Patriniae Herba, one should select the entire herb of the historically mainstream sources, P. scabiosaefolia or P. villosa from the Valerianaceae family, and choose the processing method according to the prescription requirements. It is recommended to use raw products without specific requirements.

ObjectiveTo characterize the quality differences among different germplasm and introduced varieties of Bupleurum scorzonerifolium roots(BSR), and explore the underlying molecular mechanisms, providing a basis for high-quality production and quality control. MethodsWild BSR from Yulin(YLW) served as the quality reference, we conducted comparative analysis among YLW, locally domesticated wild germplasm in Yulin(YLC3), Daqing germplasm introduced and cultivated in Yulin(YLDQC3), and locally cultivated germplasm in Daqing(DQC3). A combination of traditional pharmacognostic methods and modern multi-omics analyses was employed, including macroscopic traits(appearance, odor), microscopic features(proportions of cork, phloem, xylem), cell wall component contents(hemicellulose, cellulose, lignin), carbohydrate contents(starch, water-soluble polysaccharides), marker compound contents(ethanol-soluble extracts, total saponins, liposoluble extracts, and saikosaponins A, B2, C, D), metabolomics, and transcriptomics, in order to systematically characterize quality differences and investigate molecular mechanisms among these samples. ResultsMacroscopically, Yulin-produced BSR(YLW, YLC3, YLDQC3) exhibited significantly greater weight, length, and upper and middle diameters than Daqing-produced BSR(DQC3). Odor-wise, YLW and YLC3 had a a fragrance taste, YLDQC3 had a rancid oil odor, and DQC3 had a sweet and fragrant taste. Microscopically, Yulin germplasm(YLW, YLC3) and Daqing germplasm(YLDQC3, DQC3) shared similar structural features, respectively. However, Yulin germplasm showed significantly higher proportions of cork and phloem, as well as stronger xylem vessel staining intensity compared to Daqing germplasm. Regarding various component contents, Yulin germplasm contained significantly higher levels of ethanol-soluble extracts, total saponins, and saikosaponins A, B2, C, D, while Daqing germplasm had significantly higher levels of hemicellulose, starch, and liposoluble extracts. After introduction to Yulin, the Daqing germplasm(YLDQC3) showed increased starch, water-soluble polysaccharides and liposoluble extracts contents, decreased cell wall component content, but no significant difference in other component contents. Metabolomics revealed that saponins and terpenes accumulated significantly in Yulin germplasm, while alcohols and aldehydes accumulated predominantly in Daqing germplasm. Transcriptomics indicated similar gene expression patterns within the same germplasm but specificity between different germplasms. Integrative metabolomic-transcriptomic analysis identified 145 potential key genes associated with the saikosaponin biosynthesis pathway, including one acetyl-coenzyme A(CoA) acetyltransferase gene(ACAT), one 3-hydroxy-3-methylglutaryl-coenzyme A synthase gene(HMGS), two hydroxymethylglutaryl-CoA(HMG-CoA) reductase genes(HMG), one phosphomevalonate kinase gene(PMK), one 1-deoxy-D-xylose-5-phosphate synthase gene(CLA), one hydroxymethylbuten-1-aldol synthase gene(HDR), two farnesyl pyrophosphate synthase genes(FPPS), one squalene synthase gene(SQS), one β-amyrin synthase gene(BAS), 102 cytochrome P450(CYP450) gene family members, and 32 uridine diphosphate-glucuronosyltransferase(UGT) gene family members. ConclusionAmong the three cultivated types, YLC3 most closely resembles YLW in appearance, microscopic features, contents of major bioactive constituents, metabolomic and transcriptomic profiles. Yulin germplasm exhibits superior saponin synthesis capability compared to Daqing germplasm, and Yulin region is more suitable for the growth of B. scorzonerifolium. Based on these findings, it is recommended that artificial cultivation in northern Shaanxi and similar regions utilize the local Yulin germplasm source cultivated for at least three years.

By systematically combing ancient and modern literature, this paper examined Tribuli Fructus and Astragali Complanati Semen(ACS) used in the famous classical formulas from the aspects of name, origin, production area, harvesting and processing, clinical efficacy, so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology, and there were nicknames such as Baijili, Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas, and there were nicknames such as Baijili, Shayuan Jili and Tongjili. Because both of them had the name of Baijili, confusion began to appear in the Song dynasty. In ancient and modern times, the main origin of Tribuli Fructus were Tribulus terrestris, and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu, but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part, harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times, and the plump, firm texture, grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing, while modern commonly used is purified, fried and salt-processed. The ancient records of Tribuli Fructus were spicy, bitter, and warm in nature, with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders, improving vision, promoting muscle growth, and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today, the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed, traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter, followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior, while modern standards prioritize plump, uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying, while modern practice commonly employs purification methods. In terms of medicinal properties, the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus, its effects were thus regarded as equivalent to those of Tribuli Fructus, serving as the medicine for treating wind disorders, additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang, solidify sperm and reduce urine, nourish the liver and brighten the eye, etc. Based on the textual research results, it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials, we should pay attention to the specific reference object of Baijili, T. terrestris and A. complanatus should be identified and selected, and the processing method should be in accordance with the requirements of the formulas.
