The Effect of Plantago major Hydroalcoholic Extract on the Healing of Diabetic Foot and Pressure Ulcers: A Randomized Open-Label Controlled Clinical Trial

Abstract

Aims: Diabetic foot ulcer (DFU) and pressure ulcer (PU) both are common types of ulcers worldwide. The wound healing effect of Plantago major leaves has been shown in a few animal studies. This study aimed to evaluate the clinical efficacy of P. major hydroalcoholic extract on DFU and PU healing. Methods: In this clinical trial, patients with DFU or PU who met the inclusion criteria were randomly assigned to drug ( P. major ) or control groups. For patients in the drug group, Plantago extract 10% topical gel was applied on the wound once daily concurrent with dressing and routine wound care for two weeks, while for the control group, an appropriate novel dressing was used along with routine wound care for the same duration. The percentage of wound size reduction at the end of the seventh and 14th days of intervention was recorded and compared between the groups. Results: Fifty and 44 patients in drug and control groups, respectively, completed the interventions. Plantago extract gel significantly resulted in more reduction in the wound size compared to control at the end of the first (64.90 ± 29.75% vs. 33.11 ± 26.55%; P P P Conclusion: The use of 10% topical gel of P. major leaf extract results in the acceleration of DFU and PU healing. Key points: Application of P. major topical gel results in the acceleration of diabetic foot ulcer and pressure ulcer healing. - P. major extract helps reducing the wound's erythema.- P. major leaf extract assists decreasing the wound size.- The number of patients completing wound healing process is higher among whom undergoing P. major dressing.
