Dried hibiscus flowers, known in Mexico as jamaica (pronounced "ha-ma-ike-ah", rather than like the name of the Carribbean island country) for making a tea that is high in vitamin C. With the advent of interest in mexican cuisine, hibiscus flowers are sold in bags. This drink is particularly good for people who have a tendency, temporary or otherwise, toward water retention: it is a mild and completely natural diuretic and very good for cystitis also.

Please note that these are fine-cut and easier to make tea from.
