Botanicals have been cultured to flavour food, to treat health disorders and to put a
stop to diseases caused by various microorganisms. The awareness of curative features of
different medicinal plants has been spread among human communities. The application of herbal
products as antimicrobial agents may be a better choice for the extensive and imprudent use of
synthetic antibiotics. World Health Organization recommended traditional medicines as the safest
remedies for the treatment of diseases of microbial origin. The plant extracts are generally nonhazardous,
available in plenty at reasonable prices, biodegradable, eco-friendly and sometimes
show broad-spectrum activities against different microorganisms. The current knowledge on plant
extracts, phytochemicals and their antibacterial activity, target specific mechanism of action,
solvents deployed during extraction, properties of an active ingredient isolated may help in
biological control of bacteria. Antimicrobial properties of different plant parts, which act in a low
dose, have been organised separately for easy understanding.
Keywords: Different plant parts, phytochemicals, antibacterial activity, active ingredients, phytoextracts, bioactive compounds.
