Plants of Commercial Importance in Lesotho: Ethnobotanical and Pharmacological Insights

Abstract

Several plants have been processed in Lesotho to manufacture various commercial prodcts, ranging from cosmetics and beverages (juice, tea) to traditional herbal mixtures and crafts. Even though plants of commercial importance have been documented in different regions and countries, this is not the case in Lesotho. Therefore, the aim of the study is to record plant species commonly used in the country for development of commercial products. A physical survey was undertaken in different places in the Maseru District of Lesotho between January 2019 and October 2021, taking a record of existing commercial products and identifying plants used in their development. A total of 15 plants of commercial importance in the country are recorded in the current study, namely Agave americana, Aloe ferox, Artemisia afra, Cannabis sativa, Helichrysum odoratissimum, Hemannia depressa, Hypoxis hemerocallidea, Leudeboria cooperi, Mentha spp., Merxmuellera spp., Pelargonium sidoides, Opuntia ficus-indica, Rosa rubiginosa and Urtica urens. Most of the plants are used for production of commercial products in the country, whereas some are exported as raw materials, mainly to countries such as Germany, South Africa, Australia and America. The latter are C. sativa, Merxmuellera spp., P. sidoides and R. rubiginosa. Profiling of the plants provides important information about their commercial potential. However, conservation of the plants is encouraged to ensure their sustainable utilisation.
