Hibiscus comes from the *Hibiscus sabdariffa* plant. The tart, ruby-red flower supplies antioxidants called anthocyanins, which give it that deep color. People take it as a tea, capsule, liquid extract, or powder.
This botanical supports blood pressure that is already in the healthy range. It also promotes general heart and cardiovascular health.
A brewed tea works well for many people. Taking it with food helps avoid stomach upset. Anyone on blood pressure medication should watch their levels because hibiscus can lower pressure. It also has mild diuretic effects and may interact with certain drugs.
