Nath 11 -0001 36 39 Haritakyadi Yoga is used to treat Urinary tract infections, as mentioned in the Ayurvedic literature. In the present study, Haritakyadi Yoga formulation has been screened for antibacterial activity against selected bacterial species. The minimum inhibitory concentration of the extracts was performed by the broth dilution method. The Kirby-Bauer agar disc diffusion method studied the zone of inhibition at 2 and 4 mg/ml concentrations in DMSO solution. Nitrofurantoin drugs (5 __ampersandsignmicro;g/ml) were used as a reference control for the antibacterial study. The zone of inhibition study revealed concentration dependant nature of the extract with better effectiveness against gram-positive bacteria than gram-negative bacteria. The Haritakyadi Yoga formulation and individual components exhibited antibacterial activity against different bacterial strains responsible for Urinary tract infection.
