I suffer from chronic sinusitis and congestion. This herbal supplement has been a game changer. I don’t experience any mucus drainage! I don’t have to do sinus rinses anymore! My nose never runs or is filled with snot! This is my second order and I recommend it to anyone who suffers from excessive mucus! I was having to see a swallowing dr because I had so much drainage before trying this supplement. I would wake up from panic attacks at night because I was drowning in my own phylum. If you suffer from excessive mucus drainage this product is a game changer! I do get dry nasal passages but a diffuser helps with that!
