how to make rosemary tea?

Question

to treat skin infections

Answer 1

You can easily make your own rosemary tea by putting two tablespoons of fresh rosemary or one tablespoon of dried rosemary in a mug. Pound the rosemary lightly to release the aroma, then add one cup boiling water. Steep, covered, to desired strength. This is "drinking strength" tea -- if you are going to use it on the skin, you may want to make it stronger.

Although rosemary is a "good for what ails you" all-purpose herb, I am not familiar with using it as a treatment for skin infections. Perhaps oil of rosemary (which should not be used internally) would be better??
