WOW. These pack a punch. If it has a stimulating, menthol, or menthol-like component, it’s in here. They are quite small and not hard like candy; that is one of the things I like about them. If I were ill, these would be fantastic for clearing the sinuses. The flavor is a bit potent and not entirely pleasant, given what’s in these, but that is a small price. I’ve been using them lately for singing to keep my passages feeling clear. I often only need half of one to accomplish this.
