Abstract

BACKGROUND:

In the context of the search for cost-efficient treatments, Ulmo (Eurcyphia cordifolia) honey is an excellent alternative for treating burn wounds and could have a profound medical, social, and economic impact. Ascorbic acid is an enzymatic co-factor necessary for the synthesis of collagen and the proliferation of fibroblasts and has been proposed as a coadjuvant to strengthen the healing effects of honey. The aim of this work was to evaluate by morphometric studies the healing wounds caused by burns treated with Ulmo honey alone and supplemented with ascorbic acid in guinea pig (Cavia porcellus).

METHODS:

Fifteen guinea pigs were used and divided randomly into three groups: positive control (C+), experimental with unsupplemented honey (H), and experimental with supplemented honey (SH). A uniform deep burn covering 1 cm2 of the back skin was performed. The following indices were calculated for the morphometric study: superficial contraction index of the wound, deep contraction index of the wound, wound severity index, global healing index, global contraction index, and dermal proliferation area.

RESULTS:

The superficial contraction index of the wound, global healing index, global contraction, and dermal proliferation area values of the experimental with supplemented honey group were higher than the other groups (P < 0.05).

CONCLUSIONS:

According to these results, the combination of honey with an antioxidant (ascorbic acid) promotes an appropriate action to support the healing effect. This study showed that by supplementing the Ulmo honey with ascorbic acid, the healing and contraction effects can be strengthened in burn wounds compared to unsupplemented honey. These results were proof of the synergy between honey and ascorbic acid in healing burn wounds.
