Antibacterial activity of medicinal plants used againts gastrointestinal diseases.

Plants have been so important to humanity in all latitudes, that they have been traditionally utilized for all the cultures worldwide. Tea (herbal infusion) consumption has a variety of potential health benefits because they can prevent or lessen the effects of different pathologies, for this reason teas are considered as functional foods. A great number of tropical plants present medicinal properties, some are well known but most of them remain ignored. Return towards natural products in therapeutic use is an actual tendency nowadays. The aim of the present work was to evaluate the antibacterial activity of infusions of Malvaviscus arboreus Cav., Pimenta dioica (L.) Merr. and Tradescantia pendula var. zebrina against Staphylococcus aureus, Salmonella typhimurium and Bacillus cereus. Three grams of fresh leaves were soaked in 200 ml of boiling distilled water, let stand for 10 min and filtered. The filtered liquid was lyophilized and stored at 4°C. Antibacterial activity was evaluated using the diffusion sensibility test with paper discs and Minimal Inhibitory Concentration was determinate through tube dilution method. The infusion of Pimenta dioica was the most effective inhibiting 40% of B. cereus growth and 60% of S. typhimurium growth in comparison to positive control (Amikasine 1%). Minimal Inhibitory Concentrations varied from 1.7 to 4 mgL-1 for Pimenta dioica infusion in all the bacteria tested. In conclusion, all the herbal infusions used against gastrointestinal diseases presented effective antibacterial activity.
