If we’re strictly talking about green, white, or black tea—since those are the only true teas in the US—then fruit and herbal blends aren't actually teas at all, they're just infusions, which means such a mixture loses its inherent value.
Most of the beneficial properties found in green tea come from polyphenols, which unfortunately oxidize into catechols once they're exposed to the air. Therefore, you should seal the container as quickly as possible and ideally add a squeeze of lemon juice to prevent that oxidation process.
and make sure to drink it immediately, because it will eventually turn bitter due to the tannins.
