Antiproliferative effect of hydroalcoholic brown propolis extract on tumor and non-tumor cells.

Studies show that propolis has antimicrobial, antifungal, antiviral, anti-inflammatory, antioxidant, antitumor, and immunomodulatory properties, and may protect against diseases such as diabetes, cardiovascular disease, and cancer.
