Does chamomile tea have tannins?
Also asked, do all teas have tannins?
Generally, lower-quality teas tend to have higher tannin levels, and the longer you steep your tea, the higher the concentration of tannins in your cup. All types of tea contain tannins, but the exact amount can vary considerably depending on how the tea is produced and for how long it's steeped.
One may also ask, which teas are high in tannins?
Fermented teas such as pu-erh and oolong tea typically contain more tannins than white tea. Herbal teas (which are technically tisanes or infusions) can contain tannins. Although more is known about the effect of black tea on iron absorption, some claim that herbal tea, particularly higher-tannin tea, may inhibit iron.
In large amounts, tannic acid can cause side effects such as stomach irritation, nausea, vomiting, and liver damage. Regular consumption of herbs with high tannin concentrations seems to be associated with an increased chance of developing nose or throat cancer.
