I have allergies that cause me to cough incessantly. At night I have post nasal drip very bad. I am allergic to household molds and dust and tree pollen. I had allergy shots and medications for 8 years but when I started taking Echinacea Goldenseal root Plus obtainable from CVS pharmacy, 3 times a day with meals, my coughing stopped and my symptoms all stopped completely. Now I've cut down to one capsule twice a day and I am allergy free now. Each capsule is 450mg. the directions say you may take one capsule 3 to 6 times a day but I do not recommend it because one of the other ingredients is Cayenne Pepper. It also contains wood betony, Burdock root, Gentian root, vegetable magnesium stearate, gelatin, and Silica. The last 3 ingredients being the capsule itself.
