I've been using this stuff for about 8 years. I worked at whole foods and was the whole body specialist in the vitamin department. This stuff is the best out there! I also had chronic bronchitis as a child and in college so I have been around the block with cold medicine. I have autoimmune problems and trust this one completely! I keep it in my house and at the first sign of sickness, start taking it. I haven't been sick in YEARS! (Other than covid last year and I took this regularly! It kept me and my asthmatic lungs from going into the hospital!) Couldn't recommend this more! 5/5 100% recommended

Whenever I feel sick i take it and it helps me super fast and it tastes delicious .

Highly recommended to shorten duration or halt symptoms of respiratory illness if used at first sign of sore throat. HOWEVER, this product and regular UMCKA drops cause me to experience sleeplessness and jitters if taken at full dose (several times in past year). I now only use one dropper on back of a sore throat and notice improvement same day, then marked improvement next morning after a second mini dose. My daughter can take it 3 times a day including bedtime with no side effects. She has had remarkable success interrupting cold symptoms several times in past year using this product or UMCKA drops. Have shared tablet UMCKA w/other family members who had great success, too. (Tablets convenient for travel, but contain sugar alcohols, so I have to avoid that version.) We are unlikely to have encountered flu, so our experience to date is in response to common cold symptoms: sore throat, sneezing, stuffy head. We are stocking back-up bottles of this version plus UMCKA drops for winter. If you need it right away I have found it at Whole Foods and natural foods section of Kroger.

I've been using this product for about 5 years and anytime I feel like a cold coming on, I take it. Even if I take it well into the cold, it still only takes about 3 days to pass... I even got my wife hooked on it. It's a great cough suppressant, similar to codeine in its effectiveness. Much better than that over the counter crap you get from the store like Robitussin and Nyquil.

Actually shortens colds and flu-
