Doctor's diagnosis was bronchitis so he suggested Umcka which he carries in his office. Started taking it right away (had been about a day since first symptoms and started hacking). I believe taking it prevented the bronchitis and cough from getting worse. The usual weeks and weeks of cough were gone after 2 days! Years ago I used the cough syrup which didn't help much, but the drops seem to be much more effective.
