Real tea, that is tea brewed from the Camellia sinensis
plant, contains tannin because the leaves of the plant from which tea is made contains tannin. "Herbal teas" (also known as "tisanes"),
made from infusions of fruits or herbs may or may not contain tannin depending the nature of plant used, but most seem to contain tannin and in some instances the amount is greater than that of real tea. Lemon grass 'tea' is a tasty herbal tea that does not contain tannin if it is 100% lemon grass.
because of the curative properies of tannin in tea.
Try Rooibos also known as African Bush Tea. It has very low levels of tannin, almost zero. Celestial Seasons has a Rooibos that I enjoy and does not trigger my migraines. Do a search for Rooibos to find more information about this tea.
