What chemical quality associated with tannins in S. dendroideum aids in its traditional topical wound repair?
Answer
Tannins possess astringent qualities that tighten tissues
The topical benefits ascribed to Sedum dendroideum in traditional healing, particularly regarding wound care, are linked to the presence of tannins in addition to flavonoids. Tannins are phytochemicals renowned for their astringent properties. Astringency refers to the action of drawing together or causing the contraction of soft body tissues. When applied topically, this tightening effect helps to physically close and stabilize minor wounds, which assists in the process of tissue repair and re-epithelialization observed in animal models studying leaf extracts.
