Mullein tea is known to have a refreshing, rich, and aromatic flavor profile. It is somewhat similar to a light peppermint herbal tea in taste.

You can brew mullein tea with both the leaves and flowers of the mullein plant. Though still rich and flavourful, the leaves are slightly earthy and bitter, while the flowers have a more delicate sweetness.

Add your leaves or tea bag to boiled water, and then leave it to steep for 15 minutes to half an hour to get the full benefits of its great flavor and soothing properties. If using loose leaves, be sure to strain the tea thoroughly, as the velvety hairs from the leaves can be irritating if they end up in your cup.

If you find the taste too bitter, you can add a little honey to your cup. Some prefer mullein tea as part of a blend, with other flowering herbs such as camomile or calendula, which give it a sweeter flavor profile. This tea also works well with a touch of cinnamon.
