A comprehensive review of the botany, ethnopharmacology, phytochemistry, pharmacology, quality control and other applications of Ligustici Rhizoma et Radix.

ETHNOPHARMACOLOGICAL RELEVANCE

Ligusticum sinense Oliv. and L. jeholense Nakai et Kitag. are globally recognized as medicinal botanical species, specifically the rhizomes and roots. These plant parts are collectively referred to as Ligustici Rhizoma et Radix (LReR), which is recorded in the Pharmacopoeia of the People's Republic of China (Ch. P). LReR enjoys widespread recognition in many countries such as China, Russia, Vietnam, and Korea. It is an herbal remedy traditionally employed for dispelling wind and cold, eliminating dampness, and alleviating pain. Numerous bioactive compounds have been successfully isolated and identified, displaying a diverse array of pharmacological activities and medicinal value.

THE AIM OF THE REVIEW

This review aims to primarily center on the botanical aspects, ethnopharmacology, phytochemistry, pharmacology, toxicity, quality control, and other applications of LReR to furnish a comprehensive and multidimensional foundation for future exploration and utilization.

MATERIALS AND METHODS

Relevant information about LReR was acquired from ancient books, doctoral and master's dissertations, Google Scholar, Web of Science, PubMed, China National Knowledge Infrastructure (CNKI), ScienceDirect, classical literature, and clinical reports. Several electronic databases were also incorporated.

RESULTS

In traditional usage, LReR had been traditionally employed for the treatment of anemofrigid headaches, colds, and joint pain. It possessed therapeutic properties for facial skin disorders, thereby facilitating skin regeneration. It has been subjected to comprehensive chemical analysis, resulting in the identification and isolation of 190 compounds, including phthalides, phenylpropanoids, flavonoids, phenolic acids, triterpenes, steroids, volatile oil, fatty acids, and other constituents. The pharmacological activities have been in-depth explored through modern in vivo and in vitro studies, confirming its anti-inflammatory, analgesic, and anti-melanin effects. Furthermore, it exhibited pharmacological activities such as antioxidant, anticancer, antibacterial, and vasodilatory properties. This study provides a basic to contribute to the advancement of research, medicinal applications and product development related to LReR.

CONCLUSIONS

Considering its traditional and contemporary applications, phytochemical composition, and pharmacological properties, LReR was regarded as a valuable botanical resource for pharmaceutical and pest control purposes. While certain constituents had demonstrated diverse pharmacological activities and application potential, further elucidation was required to fully understand their specific actions and underlying mechanisms. Hence, there was a need to conduct additional investigations to uncover its material foundation and mode of action.
