An insight into leaf secretions of Asian palmyra palm: A wound healing material from nature

Abstract

The external anatomy of the tree leaves of the monocotyledon plant, Asian palmyra palm (Borassus flabellifer), differs from that of other plants in the scaly secretions on their surfaces. These secretions are used by traditional palmyra tree climbers to treat cuts or wounds inflicted by their tools during palm juice tapping. We performed a study to scientifically validate this traditional application and determine the pharmacological significance of palmyra secretion. Light microscopy, ultraviolet (UV) and Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM) were performed to characterize the scaly secretions of palmyra palm. Phytochemical investigation and biological properties like antimicrobial and wound healing studies were conducted using standard procedures. Phytochemical investigation confirmed the presence of tannins, carbohydrates, protein, terpenoids, and reducing sugar. SEM results revealed the presence of hair-like structure on the leaf secretions. Leaf secretions also exhibited enhanced antibacterial and wound healing property.
