If this device makes you feel better, I think you should use it more often. I would like someone to explain how this device works in more detail. I also often suffer from sore throats, so this information is relevant for me. In the fight against a sore throat, using biological additives that are safe for the body and have an immunomodulatory effect can also help. One of these supplements for me was chaga mushroom . It may be useful for some of you to know about this supplement. What do you use when you want to boost immunity or reduce stress?
