Pyrolae herba is the dried whole plant of Pyrola calliantha H. Andres or Pyrola decorata H. Andres (Pyrolaceae). Pyrolae herba has a long history of medicinal use in China. In ancient times, it was often used to treat pain in tendons and bones, swollen sore, cough, expectoration, bleeding, and other diseases. and was commonly used in ancient times to treat pain in the tendons and bones, swollen sore, cough, expectoration, bleeding and other diseases. This paper summarizes the botany, traditional uses, phytochemistry, pharmacology, quality control and toxicology of Pyrolae herba , with a view to providing reference for further development and research. The relevant information on Pyrolae herba was collected from the scientific databases including PubMed, CNKI, ScienceDirect, Wiley, Springer, Web of Science, Google Scholar, Baidu Scholar, Pharmacopoeia of the People's Republic of China and Flora Republicae Popularis Sinicae, etc. At present, more than 70 compounds have been identified from Pyrolae herba , including flavonoids, phenolic glycosides, quinones, terpenoids, volatile oils and other compounds. Pharmacological studies have shown that Pyrolae herba has a variety of pharmacological activities, such as anti-inflammatory, anti-bacterial, anti-viral, anti-tumor, anti-oxidation, reducing blood lipids, protective on cardiovascular and cerebrovascular, promoting osteoblast proliferation, and so on. It is used clinically in modern times to treat rheumatic arthritis, rheumatoid arthritis, bone hyperplasia, sciatica, cervical spondylosis, lumbar spondylosis, acute and chronic bronchitis, mammary gland hyperplasia, tumor, hypertension, coronary heart disease and bleeding diseases. Pyrolae herba is rich in chemical constituents, diverse in pharmacological activities and abundant in resources, which is widely used in clinics from traditional to modern. However, there is a lack of research on the relationship between chemical constituents and pharmacodynamics of Pyrolae herba. In addition, the existing clinical applications suggest that Pyrolae herba has a certain therapeutic potential in the treatment of hemorrhagic diseases, but there is a lack of information on experimental studies. It is worthwhile to further investigate the Pyrolae herba in depth in the hope of making discoveries and breakthroughs. [Display omitted] • Systematically sorted out the clinical application of Pyrolae herba. • Put forward a promising research direction for Pyrolae herba. • The hemostatic effect of Pyrolae herba has been widely used in clinical medicine in traditional Chinese medicine.
