Ethnobotany and phytochemistry of plants used to treat musculoskeletal disorders among Skaw Karen, Thailand

CONTEXT

Musculoskeletal system disorders (MSD) are prevalent around the world affecting the health of people, especially farmers who work hard in the field. Karen farmers use many medicinal plants to treat MSD.

OBJECTIVE

This study collects traditional plant-based remedies used by the Skaw Karen to treat MSD and evaluates their active phytochemical compounds.

MATERIALS AND METHODS

The ethnobotanical study was conducted in six Karen villages in Chiang Mai province using semi-structured interviews were of 120 informants. The data were analyzed using ethnobotanical indices including use values (UV), choice value (CV), and informant consensus factor (ICF). Consequently, the 20 most important species, according to the indices, were selected for phytochemical analysis using LC-MS/MS.

RESULTS

A total of 3731 use reports were obtained for 139 species used in MSD treatment. The most common ailments treated with those plants were muscular pain. A total of 172 high-potential active compounds for MSD treatment were identified. Most of them were flavonoids, terpenoids, alkaloids, and steroids. The prevalent phytochemical compounds related to treat MSD were 9-hydroxycalabaxanthone, dihydrovaltrate, morroniside, isoacteoside, lithocholic acid, pomiferin, cucurbitacin E, leonuriside A, liriodendrin, and physalin E. Sambucus javanica Reinw. ex Blume (Adoxaceae), Betula alnoides Buch.-Ham. ex D.Don (Betulaceae), Blumea balsamifera (L.) DC. (Asteraceae), Plantago major L. (Plantaginaceae) and Flacourtia jangomas (Lour.) Raeusch. (Salicaceae) all had high ethnobotanical index values and many active compounds.

DISCUSSION AND CONCLUSIONS

This study provides valuable information, demonstrating low-cost medicine plants that are locally available. It is a choice of treatment for people living in remote areas.

Pharmacological and phytochemical properties of the genus Buxus: A review

BACKGROUND

Buxus plants have been used in traditional medicine for a very long time. The Buxus genus has been used to cure a variety of illnesses.

OBJECTIVE

This review aimed to provide a literature review on the genus Buxus including its biological and phytochemical properties.

MATERIALS AND METHODS

The current study was conducted using several scientific databases. Correct plant names were verified from plantlist.org. The results of this search were interpreted, analyzed, and documented based on the obtained bibliographic information.

RESULTS

Within all the species of the family Buxaceae, 5 species of the genus Buxus are reported to be antibacterial, 3 species have been found to be antioxidant, 5 species are cytotoxic, 1 species is anti-inflammatory, 1 species is antidiabetic, and 4 species are antifungal. Alkaloids, terpenoids, tannins, flavonoids, peptides, and phenolic compounds are the main chemical components of this genus. The study of >11 Buxuss pecies has identified >201 compounds. Pharmacological research has demonstrated that crude extracts and some pure compounds obtained from Buxus have several pharmacological activities such as antibacterial, antioxidant, cytotoxic, anti-inflammatory, antidiabetic, and antifungal. Based on the study of the phytochemistry of Buxus species, it was concluded that all the studied plants have active compounds, among which 55 molecules showed interesting activities.

CONCLUSIONS

The numerous traditional uses of Buxus species have been supported by several studies. Before Buxus plants can be fully employed clinically, further research is necessary.
