This worked better than I expected. I didn't have high hopes initially, I saw this on sale and thought why not. I caught a head and chest cold. I was congested, dry cough, with sinus pressure. I took these partnered with mullein leaf, and extra nettle. It helped my asthma, allergies, breathing and overall sinus pressure. I went one does with just the herbs and it was not as effective as my doses with Natural Factors. I recommend this product for anyone that suffers with chronic chest, bronchial, allergy, or asthmatic issues.
