Using whole or minced, dried or fresh rosehips, with just enough water to cover them in a medium sized saucepan. Steep and strain. I give amounts in the recipe below, but they're not sacred - feel free to experiment with your own amounts. The less water, the more concentrated the tea and the stronger the flavor.
Bring water to finger hot temperature of around 100 °F/38 °C and cover rosehips and Goji berries (also high in Vitamin C), if using.
Steep for thirty minutes. The longer it sits, the stronger the tea.
Add raw honey and lemon juice.
Notes
The resulting tea is tepid but best for retaining as much Vitamin C as possible. If you prefer to heat the water a little warmer, add some powdered citrus peel to the tea once it has cooled to finger-test warmth (around 100 °F/38 °C). This will provide yet another source of Vitamin C.Remember that this is a folk recipe and doesn't require specific amounts. Because Vitamin C is water soluble, if you end up ingesting "too much", your body will simply remove it from your system with your urine. You'd probably have to drink gallons of this tea before it could be considered too much, but there you go.
