Use about 1-2 teaspoons of dried rosehips per one cup of water. You can either steep it or boil it. In a small saucepan bring water to boil and add dried rosehips to a boiling water. Let it boil over low fire for about 10 to 15 minutes. Alternatively, bring fresh water to a boil and let the rose hips steep for 10-15 minutes in a covered teapot or a mug.
