Chronic bronchitis is commonly, a component of chronic obstructive pulmonary disease (COPD), both caused by cigarette smoking. Both humidity and cold weather can aggravate COPD. Wood stoves, especially if not well ventilated, can lead to COPD, certainly be responsible for its worsening and prolong the course of the common cold. Do not depend upon visual examination of the stove to determine if products of combustion are entering the room. When you are outside, try wearing a cold-weather mask, which are available at most medical supply stores.
Thank you for the information. I ordered the Ayurvedic Bronchial Formula.
