Snail extracts have been increasingly used in numerous dermatologic conditions and recent literature attributes healing, soothing and anti-aging properties to them. This study evaluates the efficacy of Helix aspersa extract in an open wound management protocol for deep partial thickness (PT) facial burns and compares it to moist exposure burn ointment(MEBO). A total of 27 adult patients with deep partial thickness facial burns (group A) were treated by application of a snail extract cream twice daily for a maximum period of 14 days or until full epithelialization. Times until debridement and epithelialization of the burn surface were compared with those of 16 patients (group B, control) treated by MEBO. Pain scores were recorded using a visual analogue scale (VAS) on the fourth post-burn day before and 30 min after application. Mean times for eschar detachment were 9 +/- 2 days (group A) and 11 +/- 2 days (group B) (p = 0.003) and for burn surface epithelialization were 11 +/- 2 days and 15 +/- 3 days respectively (p < 0.001). VAS pain scores after application in group A were significantly lower compared to group B (p < 0.001). Helix aspersa extract is a natural, safe and effective alternative treatment in open wound management of partial thickness burns in adults.
