| Roselle fruits (Hibiscus sabdariffa, L.)* |
The plant produces attractive red to purple flowers and fruits. It has been cultivated for centuries in Asia, Africa and South America. Traditionally communities in these continents consume the fresh leaves and fruits in their meals while those dried are infused in warm water to prepare the medicinal "sour tea". The sourness is probably due to the natural acids released including ascorbic acid (vitamin C).
