Antimicrobial Activity on Daun Gatal: a Literature Review

Abstract

Daun gatal (Laportea decumana) is well known in the Papuan province for its analgesic properties. Traditionally, the muscle fatigue relieving effect is obtained by applying Laportea decumana leaves on the skin of the sore area for 5-10 minutes until itchiness ensues. This may not be the only benefit of Laportea decumana, as studies done on its close relative Laporteaa estuans indicate that Laportea decumana may also have significant antimicrobial activity. This hypothesis is supported by a recent study on the antimicrobial properties of Laportea decumana that found antibacterial activity on Staphylococcus aureus and Escherichia coli. To answer this hypothesis, this study will gather data on phytochemicals and antimicrobial activity of Laportea decumana, Laportea aestuans, and Laportea crenulata to help identify this antimicrobial activity on Laportea decumana. Data on antimicrobial properties and phytochemicals of Laportea decumana, Laportea aestuans, and Laportea crenulata will be extracted from Google Scholar and PubMed databases, while additional data on other biochemicals that contribute to the antibacterial properties of Laportea decumana will also be provided. This will be supplemented with in situ Daun gatal extraction data. The goal of the study is to provide an avenue of research on the future uses of Laportea decumana extract for its antibacterial activity.
