After forming the aqueous extract of Lawsonia inermis, it has no antibiotic activity and the antibiotics are not detectable by chemical analysis. The aqueous extract of Lawsonia inermis is stable for at least 28 days for the topical treatment of wounds and has been stable up to two years in clinical testing. The aqueous extract of Lawsonia inermis extract is applied with a spray to the surface of the wound, followed by the application of an extract-soaked gauze dressing to the surface of the wound.
