“…The plant's rhizome is extensively used in Thai cooking for its unique ginger‐like flavor accompanied with a tinge of pungent and peppery odor (Juntachote and others 2007). Furthermore, this plant's rhizome is also used for medicinal purposes, which is reported to exhibit antifungal, antigardial, antiamebic, antimicrobial, and antioxidant activities (Juntachote and Berghofer 2005;Phongpaichit and others 2005; Oonmetta‐aree and others 2006; Voravuthikunchai and others 2006; Juntachote and others 2007; Hsu and others 2010).…”

“…By employing the agar disc diffusion method, antimicrobial activity of galangal flower buds against both Gram‐positive and Gram‐negative bacteria have been tested. The effects of drying methods (oven drying and freeze‐drying) and solvents (hexane and ethanol) on the antimicrobial activity have also been investigated (Hsu and others 2010). Galangal was shown to be effective against Gram‐positive bacteria ( Listeria monocytogenes and S. aureus ) but exhibited little or no effect against Gram‐negative bacteria ( Salmonella spp ., E. coli O157: H7 , and Shigella spp.).…”

Plants with potential therapeutic value have been used from time immemorial to cure various ailments and infectious diseases. Secondary metabolites or the bioactive compounds (phytochemicals) present in plants have been reported to be accountable for various observed biological activities. Consumer awareness of the possible side effects of using chemical-based antimicrobial agents has forced researchers to identify and explore natural plant-based antimicrobial agents (or preservatives) that are toxicologically safe, especially when used in food applications. Of late, scientific evidence has been provided on the potential antimicrobial activities exhibited by certain traditionally used flower extracts or their essential oils (edible and wild). This review focuses on providing and updating available information on the antimicrobial activities exhibited by flowers, which are envisaged to find potential applications as natural preservatives for foods or applications in the pharmaceutical industries to develop new and economical herbal-based products for treating various diseases.

Alpinia galanga (Zingiberaceae) or lengkuas is one type of herbal plant that is widely grown in Southeast Asia. Various countries cultivate this medicinal plant, including Indonesia. This medicinal plant has a variety of benefits and also be used as a treatment for many diseases. Although the lengkuas rhizome is the most widely used and studied part of the plant, the flower on the lengkuas can also provide additional advantages, such as antioxidant and antimicrobial properties. Therefore, this study aimed to demonstrate lengkuas for the future prospects against SARS-CoV-2. In summary, this study suggests that lengkuas might be useful as a treatment for COVID-19, although further studies could be conducted to confirm the results of computational studies.
