The plant is known as Mayaphal and Majufal in Hindi. Quercus infectoria gall extract has the potential to generate herbal metabolites. the crude extracts demonstrating anti-dental caries activity could result in the discovery of new chemical classes of antibiotics. These chemical classes of antibiotics could serve as selective agents for the maintenance of human health and provide bio-chemical tools for the study of infectious diseases (Vermani & Navneet 2009).
