Raspberry (Rubus idaeus) is a plant native to North America. The women of the Potawatomi tribe from the Great Lakes region brewed tea from the leaves, which were highly valued because of their unique astringent properties. The tea remains popular among midwives and herbalists today. Alvita Raspberry Tea is made with premium-quality, organic raspberry leaves, and produces an amber colored tea with a mild herbal aroma and a flavor reminiscent of traditional green tea. Preparation: Place one tea bag in a cup and add 8 oz of boiling water. Cover and steep for 5 minutes. Gently squeeze tea bag and remove.
