I have no idea what three of the ingredients are. This makes for an educational cup of tea, but also for too much going on in my mouth at once. Gynostemma is a vine kind of used like ginseng. But not with it’s taste or after taste. Eyebright powder? Huh, apparently it " contains several beneficial plant compounds". Horsetail. Very interesting. " It was used traditionally to stop bleeding, heal ulcers and wounds, and treat tuberculosis and kidney problems." Guess I got in all my good stuff tonight. My palate still doesn’t like it though.
