Abstract
Objectives: Premna barbata Wall. ex Schauer; (Lamiaceae) is a deciduous shrub or tree
known as Aganyo in folk language. The plant is widely used in treating various diseases traditionally,
such as arthritic pain, dropsy, diarrhoea, fever, and herpes complex disease. However, comprehensive
data on this medicinally important plant is not available in the literature. Therefore, this review aims to
provide a detailed overview of the botanical description, ethnomedicinal use, phytochemistry, and
pharmacological investigations of Premna barbata to provide a scientific consensus for future research
investigations and to link its traditionally claimed use to scientifically proven results.
Methods: Information regarding the plant was gathered from electronic databases such as Science
Direct, PubMed, Web of Science, Wiley Online Library, ACS, Springer, SciFinder, Taylor and
Francis, Google Scholar, Scopus and Journal websites. The scientific name of the plant was validated
using The Plant List and The International Plant Names Index.
Results: An exhaustive study of the accessible sources of Premna barbata confirmed its origin, distribution,
and ethnomedicinal use. It has been used in the form of powders, juice, paste, and decoctions
against various ailments. Phytochemical analysis revealed the presence of different phytoconstituents.
Only antibacterial potential of the plant has been reported yet.
Conclusion: By performing the literature search, Premna barbata showcased its importance in folkloric
medicine as well as in ayurvedic medicine. Moreover, the collected information from various
trustworthy sources shows that the plant holds many hidden potentials and can, therefore, be studied
extensively for its quality control, pharmacognosy, phytochemistry and pharmacological activity.
Furthermore, in-depth studies are required to discover key features which can help in future research
work. An effort is required to investigate this plant species, which is found distributed in most unexplored
regions as well as it needs to be preserved as it’s on the verge of extinction.
Keywords:
Premna barbata, traditional uses, phytochemistry, premnosidic acid, pharmacology, ethnopharmacology.
