blend of Chinese herbs, but Extra Strength has a 50% stronger dose (larger capsule), and both Liquid and Extra Strength also contain a homeopathic formula for fast relief of congestion (and are treated as drugs, not supplements). We recommend the classic Chinese Herbal Formula (red label) for daily use if needed, while Liquid or Extra Strength (blue label) can be used for fast relief of lung congestion, for example during allergy season, or if you have a cold or flu.
Adults and children age 12 or over, take 2 capsules (under age 12, take 1 capsule) every 4-8 hours as needed to maintain healthy lung function. Results are usually felt within hours, and increase with continued use. Once desired results are obtained, try 1 or 2 capsules twice daily for maintenance. May be used indefinitely if desired, or as needed for seasonal or temporary conditions.
