Effect of a Semisolid Formulation of Linum usitatissimum L. (Linseed)‎ Oil on the Repair of Skin Wounds

Abstract EN

The purpose of this study was to investigate the effects of a semisolid formulation of linseed oil, SSFLO (1%, 5%, or 10%) or in natura linseed oil on skin wounds of rats.

We used wound models, incisional and excisional, to evaluate, respectively, the contraction/reepithelialization of the wound and resistance to mechanical traction.

The groups (n=6) treated with SSFLO (1% or 5%) began the process of reepithelialization, to a significant extent (P<.05), on the sixth day, when compared to the petroleum jelly control group.

On 14th day for the groups treated with SSFLO (1% or 5%), 100% reepithelialization was found, while in the petroleum jelly control group, this was only 33.33%.

Our study showed that topical administration of SSFLO (1% or 5%) in excisional wounds allowed reepithelialization in 100% of treated animals.

Therefore, a therapeutic potential of linseed oil, when used at low concentrations in the solid pharmaceutical formulations, is suggested for the process of dermal repair.
