I got this for my wife and mother in law, 83yo, before the long winter months set in. Both lifetime smokers, it helps keep mucus to a minimum therefore helping stave off upper respiratory infections. I usually harvest 2 of the 3 ingredients on my farm and they helped many a family member or friend, but the drought this year brought a less than satisfactory harvest. I’ve been using Dr. Morse products for years and will continue to due so. I’m thankful to have a reliable source when in need for my holistic healing practice.
