Detailed Description

Lichen planus is a common chronic mucocutaneous disease of uncertain origin that has been shown to affect 0.5% to 2.2% of various populations. The treatment options for OLP are numerous and include topical and systemic agents. Steroids were found effective in management of OLP with contraindicated use in some systemic diseases and with multiple side effects with its prolonged use. Pomegranates have been known for hundreds of years for their multiple health benefits, including anti-inflammatory activity. The recent surge indicates that pomegranates and their extracts may serve as natural alternatives to drugs which can offer a possible management of OLP decreasing pain and discomfort associated with this chronic condition.The aim of this study was the evaluation of the effect of topical pomegranate extracts in management of oral lichen planus lesions (OLP).
