advantages like fewer side effects and are cheaper in price over modern drugs but

have some limitations like low bioavailability. The impregnation of herbal drugs into

proper delivery vehicles improves its bioavailability and sustained its release over

the wound site. The herbal drug-impregnated wound dressing materials exhibit

better cell attachment, proliferation, differentiation and antimicrobial properties

and increase the overall quality of wound healing. The future direction of wound

management includes the design of the drug-impregnated systems using shape

memory polymers which will change its shape with healing of the wound and

deliver the drug molecules either through controlled release, changing the shapes

or combining all these therapies for effective wound management (Biswas et al.

2016, 2018c, 2019a, b).
