Swisse Ultiboost Lung Health Support is a harmonious blend of East and West, tradition and science. This premium quality formula contains zinc, selenium and vitamins C and E as well as herbs used in traditional Chinese medicine to tonify lungs and help relieve coughs. Speaking of, we’d like you to meet astragalus and reishi mushroom. Picked from nature, these ingredients might not be household names, but that's not to say they shouldn’t be. Astragalus is traditionally used in Chinese medicine to support lung tonification, while reishi mushroom is traditionally used in Chinese medicine to dissolve phlegm. Take three tablets daily, during or immediately after a meal.
