The deep red tea produced by hibiscus (Hibiscus sabdariffa L. ) comes from the vibrant red flower buds, or calyces, that are harvested just prior to blossoming. While long used as a fragrance in perfumes and sachets, as well as an ingredient in jams and jellies, ancient herbalists recognized the unique benefits of this herb, and traditionally used hibiscus tea to support the cardiovascular system.* Alvita Hibiscus Tea is made with premium-quality, organic hibiscus calyces, and exudes a refreshingly tart flavor and light floral aroma. Naturally caffeine free. Certified Organic by QAI. Certified Gluten-Free by NSF. Certified Kosher by Star-K. *These statements have not been evaluated by the Food and Drug Administration.
