About Sorrel (Hibiscus)

Sorrel (Hibiscus) (Hibiscus sabdariffa) is a herb used in the Caribbean Folk Medicine tradition to help with High Blood Pressure, Cholesterol, Kidney Support, and Liver Support. The flowers / calyces are the part traditionally used, taken internally.

Botanical background

Roselle (Sabdariffa gossypiifolia) is a species of flowering plant in the genus Sabdariffa that is native to Africa, most likely West Africa. In the 16th and early 17th centuries it was spread to Asia and the West Indies, where it has since become naturalized in many places. The stems are used for the production of bast fibre and the calyces are commonly steeped to make an infusion popular in many places around the world.

Quality tips

When buying Sorrel (Hibiscus), look for: certified organic labelling, clearly stated country of origin, third-party lab testing for heavy metals and pesticides, and a batch expiry date. Standardised extracts offer consistent dosing; bulk dried herbs are more economical for regular use. Avoid very cheap, unlabelled products — quality varies enormously.
