When is an expectorant useful? Whenever you need bronchial support. As we all know, chest congestion can hit any time of the year. Having a convenient expectorant handy when you need clear bronchial airways lets you breathe easy at the office, or a day at the park. Why use Air-Power®? It clears bronchial airways and helps loosen phlegm. Air-Power contains the active ingredient glycerol guaiacolate, in a base of herbs and other ingredients. This formula helps make coughs more productive by helping loosen excess phlegm (mucus) from respiratory airways due to bronchial irritations. It's convenient. Because Air-Power is a tablet, there's no fuss. Plus, you don't have to worry about a bottle that can leak all over your backpack or bag. It can be used by the whole family.
