The human trachea has ciliary cells all over its inner surface. These cilia constantly vibrate at a rate of about 1500 times a minute, and the inner walls of the trachea secrete mucus. Dust and other foreign particles that com into the body through the trachea are caught by this mucus and are ejected out of the trachea by the vibration of the cilia. This is the natural process of keeping the respiratory system clean and healthy. Ryukakusan, because of its saponin content stimulate the secretion of mucus from the inner surface of the trachea, invigorate the cilia to remove sputum and, therfore promotes a healthy respiratory system.
