I've been using these over 20 years while living in Trier. Was skeptical at first but these work better than anything I tried.You won't be disappointed.
Underberg Natural Herb Bitter - 2017 Collector's Tin reviews
My husband was drinking alka seltzer almost every night and I gave Underberger to him to try and he hasn't used alka seltzer since. He drinks a small amount each night after dinner and has no indigestion now! It is natural and much safer to use than over the counter products.
If one ever has stomacch pain one little bottle of Underberg will help , for sure
