Summary of article contents:
Introduction
Recent interest in traditional medicine has surged, recognizing the therapeutic potential of various plants, including Bauhinia variegata L., commonly known for its wound healing properties. Originating from Southeast Asia and belonging to the Leguminosae family, all parts of this plant have been used in traditional treatments for various ailments. This study specifically investigates the aqueous extract of Bauhinia variegata stem bark for its efficacy in enhancing wound healing in diabetic albino rats.
Wound Healing Properties
The study demonstrated that the aqueous extract of Bauhinia variegata significantly enhances wound healing activity. It was observed that the formulation containing 4% extract was superior to the control and standard neomycin ointment. Prominent effects included increased cell proliferation, formation of granulation tissue, and enhanced collagen synthesis, leading to improved wound contraction rates. These results underline the plant's potential as a natural remedy for accelerated wound healing.
Formulation and Efficacy
Various ointment formulations with different concentrations of the Bauhinia variegata extract were prepared to assess their effects on wound healing. The ointments were developed using polyethylene glycol bases, which allowed for effective drug release and skin compatibility. The treatment groups showed significant reductions in wound area over time, with the 4% extract formulation achieving the fastest healing compared to control and other formulations. This indicates that the concentration of the active extract plays a vital role in therapeutic efficacy.
Histopathological Findings
In histopathological evaluations, the tissues healed with Bauhinia variegata showed enhanced keratinization, epithelization, and collagen formation compared to untreated controls. The study's observations emphasized that the plant extract not only promotes better structural healing of the tissue but also provides a favorable environment for cellular repair. The histopathological markers evidenced improved wound architecture, reflecting the positive impact of the plant extract in wound healing processes.
Conclusion
The findings highlight the promising wound healing capabilities of Bauhinia variegata, particularly in diabetic conditions where wound healing is notoriously complicated. The extract enhances various healing parameters, including contraction, tensile strength, and hydroxyproline content, indicative of improved collagen synthesis. The histopathological results further clarify the plant extract's role in promoting tissue repair and reducing inflammatory reactions. Future research is warranted to isolate and identify the active compounds responsible for these beneficial effects and to better understand the underlying mechanisms of action.
