Medicinal plants as alternative and adjunct antimicrobial agents in ear, nose, and throat (ENT) Infections

Medicinal plants are widely used worldwide for ear, nose, and throat (ENT) disorders and have a long history of traditional application. This review aims to summarize current experimental and clinical evidence on medicinal plants used for ENT conditions such as otitis externa/media, tinnitus, vertigo, allergic rhinitis, pharyngitis, and laryngitis, and to support the identification of new plant species with antimicrobial potential against ENT pathogens. This review thoroughly summarizes recent developments from 2020 to 2025 and was conducted using electronic databases, including PubMed, Web of Science, Scopus, ScienceDirect, and Google Scholar, with predefined ENT and medicinal plants-related keywords. Frequently used species include Lavandula angustifolia, Thymus vulgaris, Curcuma longa, Zingiber officinale, Origanum vulgare, Glycyrrhiza glabra, Mentha piperita, Matricaria chamomilla, and Syzygium aromaticum, many of which show In vitro antibacterial, antifungal, or antiviral activity relevant to upper airway and oral/ENT infections. Evidence indicates that selected medicinal plants and their extracts or essential oils inhibit key ENT-related pathogens, including multidrug-resistant respiratory and pharyngeal bacteria. The compiled data, structured in comparative tables, highlight promising taxa and preparation types, and underscore gaps in clinical validation, standardization, and safety assessment. Overall, this review provides an evidence-based overview of ENT-related phytotherapy and a framework for future pharmacological and phytochemical studies aimed at developing novel plant-derived antimicrobials for ear, nose, and throat diseases.
