Huaxi Yurong's products are very good, especially the ice crystal water has a quick effect on acid reflux. Once I got carsick by car, the sour water in my stomach kept rising and I was about to throw up. Later, I sprayed the ice crystal water in my bag into my mouth a few times, and it took less than a minute. After a five-hour ride, I didn't feel dizzy when I got home, so I thought Huaxi's products were good. You can try.
