Abstract
The invention is directed to an aqueous extract of Eruca sativa (arugula) leaves that has antimicrobial activity on Gram-positive bacteria and mycoplasmas. The extract may be purified away from solid or insoluble components, standardized based on the weight of its non-aqueous or solid content, assayed for antimicrobial activity, and provided in an aseptic or sterile form for pharmaceutical use. It may be used to kill or inhibit the growth of microorganisms such as Gram positive bacteria, promote wound healing, or as prophylaxis against host colonization or infection by a microorganism.
Claims7
A skin treatment method for inhibiting the growth of a Gram positive bacterium on skin after shaving, comprising:
- preparing an aqueous Eruca sativa extract by:
- grinding a sample consisting of dried leaves of a Eruca sativa plant,
- macerating the ground leaves of the Eruca sativa plant with an extractant consisting of water to extract the leaves of the Eruca sativa plant for a period of days at a temperature of about 25° C. to extract water-soluble components from the leaves of the Eruca sativa plant then filtering to form a first extract,
- concentrating the first extract under vacuum to produce the aqueous Eruca sativa extract in the form of a concentrated extract liquid, then
- dispensing an aqueous composition comprising the concentrated extract liquid and at least one of an ionic surfactant and an amphoteric surfactant from a dispenser in the form of a foam,
- applying the foam onto a shaved skin surface to contact the Gram positive bacterium with the foam to inhibit the growth of the Gram positive bacterium, wherein the Gram positive bacterium is Cellulomonas strain B22.
