Aloe arborescens (Candelabra Aloe) has been used in the treatment of upper respiratory tract infections in Central and Eastern European countries for many decades. Originally introduced to support the healing and recovery in cornea transplant patients, aqueous A. arborescens extracts soon became popular in the treatment of upper respiratory tract infections with a focus on toddlers and children. Recent preclinical and clinical data show that immunomodulatory, antiinflammatory, and antiviral effects contribute to its therapeutic efficacy. Based on its well documented, longstanding traditional use and its excellent safety and tolerability, A. arborescens may be considered a valuable addition to the spectrum of herbal medicinal products for the treatment and prophylaxis of upper respiratory tract infections, in particular common cold, in adults and children.
