Great product!
I get a dry cough from occasional acid reflux and these lozenges have really helped manage a flare up. They really do the job. These are not cough drops per se, but they seem to coat the throat and help keep coughing spells at bay.

Very helpful for Sjögren’s dry mouth.
Living with Sjögren’s, dry mouth is something I deal with every day, and these lozenges have been very helpful for comfort. They dissolve slowly and help my mouth feel more moisturized and less uncomfortable, especially during long days or when I’m talking a lot. They’re easy to use, have a pleasant taste, and are convenient to carry with me. I like having them as part of my daily routine to help manage dryness and feel more comfortable.
