Hibiscus (Hibiscus sabdariffa), also known as roselle or sour tea, is a vibrant flowering plant prized for its deep red colour, tart, refreshing flavour, and long history in traditional wellness practices around the world. The dried calyces are brewed into a beautiful ruby-coloured tea enjoyed hot or iced across Africa, the Caribbean, the Middle East, and Latin America. Hibiscus is exceptionally rich in antioxidants, particularly anthocyanins and polyphenols, which give it both its striking colour and many of its health-supporting properties. Today, hibiscus is one of the most well-researched herbal teas, especially valued for its support of heart health and antioxidant protection.
