Garden cress (Lepidium sativum L.), a member of the Cruciferae family, is widely planted across the world, especially in India, Europe, and the United States. It has been respected as a key medicinal plant from the time of the Vedic culture. Lepidium sativum Linn. seeds were tested for their efficacy as an antibacterial agent against pathogens found in food. The active components were extracted from the powdered dry seeds using chloroform, ethyl acetate, methanol, and dichloromethane. The antibacterial activity of various doses of the extracts was evaluated using agar well diffusion. We also estimated the MIC and MBC for the most effective extract using the tube dilution technique and the subculturing method, respectively. One of the most common mosquito species that carries Plasmodium falciparum is the Anopheles gambiae sensu lato, which may be combated by sprinkling fields with Lepidium sativum seeds. Scientists have begun to extract essential oils from Lepidium sativum and evaluate their bio-potential against juvenile and adult Anopheles gambiae as part of an attempt to identify ecologically viable vector control tactics. Based on the findings, it is clear that L. sativum essential oil effectively kills An. gambiae. Although field application on a wide scale is necessary for An. gambiae population control, more work has to be done in formulation and assessment.
