I got this for my husband because of the change in the weather. He had been waking up with drainage in his throat that was causing him to cough. After trying Colloidal Silver: Nature's Antibiotic, he noticed his throat felt more comfortable, and the drainage seemed to improve. It was easy to use, and we're happy to have it on hand during seasonal weather changes. Overall, we've had a positive experience with this product and would consider purchasing it again in a bigger bottle.
