Have you been struggling with seasonal allergy symptoms? After much searching I have found an herbal formula which works very quickly and effectively with absolutely no drowsiness or foggy feeling. Aller Dx is a Chinese herbal formula which improves immune system tolerance to the environment. Within 10-20 minutes, histamine response is calmed and nasal airflow is much improved. This is the most effective natural treatment for seasonal allergies that I have found. The company that makes this product also has a very effective cold and flu formula which I will be carrying starting in the fall. Please contact us if you would like more information!
