Royal Jelly for Wound Healing

Research suggests that royal jelly may support wound healing through multiple biological mechanisms, including antimicrobial activity, reduction of inflammation, promotion of skin cell growth and migration, and stimulation of new blood vessel formation. The body of evidence includes in vitro studies, animal models, and several reviews, with a notable cluster of recent research focusing on royal jelly-derived extracellular vesicles — tiny membrane-enclosed particles that appear to carry much of the substance's therapeutic activity — and which have shown accelerated wound closure in mouse and pig models, including in the context of diabetic wounds. Studies have also identified specific proteins in royal jelly, particularly Major Royal Jelly Proteins 2, 3, and 7, as likely contributors to its wound-healing properties, and researchers have explored its incorporation into hydrogel dressings and combination formulations with other materials. However, the overall evidence base remains largely preclinical, with most findings coming from cell culture and animal experiments rather than controlled human trials, and reviewers consistently note limitations such as variability in royal jelly's composition depending on geographic and botanical origin, inconsistent dosing across studies, and the need for more rigorously designed clinical research before firm conclusions can be drawn.
