Abstract

Background: Wound healing is a dynamic and complex process affected by tissue hydration, the presence of bacteria, inflammation, and other variables. Oregano has potent antibacterial, antifungal, antioxidant, and anti-inflammatory properties. Studies of oregano ointment on wound healing are lacking. Objective: To determine the efficacy of 3% oregano extract ointment on wound healing. Methods: An investigator initiated, randomized, double-blind, petrolatum-controlled study was performed to determine the effects of oregano ointment on wound healing. Forty patients who underwent surgical excision were enrolled and randomized. Cultures were obtained on day 12 and scars were evaluated using the Patient and Observer Scar Assessment tool on day 12, 45, and 90. Results: The oregano ointment group had 19 percent of cultures test positive for Staphlococcus aureus compared to 41 percent in the petrolatum group. One patient in the oregano ointment group developed a cellulitis compared to three patients in the petrolatum group. The oregano group had a statistically significant improvement over petrolatum in scar color, pigmentation, and pliability. Conclusion: Oregano extract ointment decreased bacterial contamination and subsequent infection on post-surgical wounds and had equivalent overall scar appearance compared to petrolatum.

Abstract

AIM OF THE STUDY:
Hypericum perforatum L. (Hypericaceae), olive oil (Oleaceae), Origanum Tourn ex L. and Salvia L. species (Lamiaceae) are used against inflammatory disorders and for healing of skin wounds in traditional Turkish medicine. A new ointment formulation was developed to provide more efficient wound healing activity. The content of the formulation was as follows; olive oil extract of flowering aerial parts of Hypericum perforatum L., olive oil, an equivalent mixture of Origanum majorana L. and Origanum minutiflorum Schwrd. et Davis essential oils (Origani aetheroleum), Salvia triloba L. essential oil. The aim of the present study is to assess the wound healing potential of this new formulation by using in vivo and in vitro models as well as histopathological methods.

MATERIALS AND METHODS:
For the evaluation of wound healing potential of this formulation (HPP crème mit Rotöl ointment) in vivo wound healing experimental models were employed on rats and mice and the efficiency was comparatively assessed against a reference ointment Madecassol(®). Tissue sections were also evaluated histopathologically. Furthermore, the wound healing activity of each component was also investigated individually to determine the improvement in the healing capacity of the formulation.

RESULTS:
The ointments of HPP crème mit Rotöl and Hypericum perforatum L. demonstrated the highest activities on both wound models when compared to reference ointment Madecassol(®), while the other ingredients did not show any remarkable wound healing effect. However, the efficacy of the formulation was remarkably higher than the Hypericum L. ointment alone which was also confirmed by histopathological evaluation. On the other hand, the formulation did not reduce elastase activity in vitro, but inhibited the collagenase activity. HPP crème mit Rotöl also exerted bactericidal and candicidal activities.

CONCLUSIONS:
The experimental studies revealed that HPP crème mit Rotöl formulation displays remarkable wound healing activity. To be acting on the different stages of wound healing process could be considered as a beneficial effect of the formulation for the treatment of wounds.
