Lots of comments talking about product quality and research, and that’s totally true. However bear in mind that when it comes to infusions, the effects are likely to always be mild, and you also have a lot of personal taste influencing your reaction.

Take for example camomile, which has anti inflammatory properties. But how much camomile are you consuming with a single cup of camomile"tea"? Not much; also, the effects are topical ( on contact), and a drink usually doesn’t stay for too long on the same spot of your throat. A cup of camomile isn’t going to make a massive difference if you have inflammation on a tooth gum or your throat, and it won’t do anything for inflammation on your knee. And if you dislike the smell and taste, that’s not going to help at all.
