Organic Khartoum Hibiscus Flowers offer a tangy flavor with a deep red infusion, sourced straight from the Nile River Delta in Khartoum. With zero caffeine, this tea is rich in vitamin C and has many reported health benefits. Many people drink hibiscus as is - steeped plain in water at a boil for five or more minutes, but it is also nice to prepare on the stovetop with a couple of cinnamon sticks added and maybe just a touch of sugar to round out the natural tartness of the flowers.
