Originally formulated as Lung Lymphatics formula in 1977 and then Clear Lung in 1992, RespriClear by PHS is the original clinically formulated herbal remedy for thinning, clearing and drainage of the Lungs and Lymphatic systems. The original formula has been helping people with breathing and respiration difficulties since that time. Used in multiple health clinics and the first choice for Naturopathic Physician's recommendation, it has stood the test of time as the premier remedy for respiratory congestion.
