Quercetin is a very potent antioxidant free radical fighter found in many fruits and vegetables. It is also known as a anti-histamine and a anti-inflammatory. Bromelain is derived from pineapple. Together they make a perfect combination and have so many uses, let me name a few: allergies, irritable bowel syndrome, colitis, arthritis, asthma, swelling due to surgery, sports injury, dental procedure, just to name a few. I personally use it for seasonal allergies as it helps as an anti-histamine & for my asthma. I have been giving this to many of my friends and family and it has helped them out significantly. Give it a try for yourself, it’s all natural and can be found at your local health food store. I buy it from iherb.
