Antibacterial Activity of Thai Medicinal Plant Extracts Against Oral and Gastrointestinal Pathogenic Bacteria and Prebiotic Effect on the Growth of Lactobacillus acidophilus

The 25 crude methanolic extracts of Thai medicinal plants were tested for their antibacterial activity against 10 bacterial strains using disk diffusion assay and minimum inhibitory concentration (MIC) determination. Rhubarb (Rheum palmatum) root, wild turmeric (Curcuma aromatica) rhizome, aleppo oa...
