What is hibiscus?

The Hibiscus genus contains several species, many of which have been used medicinally. For instance, Hibiscus rosa-sinensis has been documented in the ancient Indian scriptures. Hibiscus sabdariffa has been used as a folk medicine in Canada, and appears promising in treatment of hypertension (high blood pressure). Hibiscus cannabinus has been studied to treat head lice, although there is currently insufficient available evidence in this area.

Hibiscus sabdariffa and compounds isolated from it (for example, anthocyanins and hibiscus protocatechuic acid) are likely candidates for future studies. There is limited reported safety data about hibiscus, although it is popularly used as a tea.
