Coconut oil, Neem oil and Aloevera gel were mixed with the medicinal plants separately to screen them for their antibacterial activity. Agar well diffusion technique was carried out. Among these three plants Thespesia populnea fruit with coconut oil and aloevera gel showed high zone of clearance when compared to others. Copyright@ International Science Community Association
