Euphorbia hirta has been widely used by Tribal as traditional medicine in a treatment against infectious pathogens. E. hirtaLinn. is a perennial. diffusion method was used to determine the antibacterial activity on gram negative: Euphorbia hirta plant displayed an excellent antibacterial activity against K. The antibacterial and antifungal effect of Euphorbia hirta was evaluated against a panel of bacteria (Escherichia coli, Psueudomonas aeruginosa, Klebsiella.
