Amazonian Guarana- and Açai-Conjugated Extracts Improve Scratched Fibroblast Healing and Surgical Tail Amputation by Modulating Oxidative Metabolism.

Background: Previous studies have suggested that guarana () and açai () have antioxidant, anti-inflammatory, and proliferative properties, indicating their potential therapeutic action in wound healing. We produced a conjugated guarana-açai (GA) extract and tested its healing action on earthworms () subjected to tail amputation by surgical incision.
