Hibiscus

Also known as: roselle, Hibiscus sabdariffa

Roselle hibiscus is a plant whose calyces are used for a tart red tea rich in anthocyanins. Smaller studies suggest a modest reduction in blood pressure.

What it is used for

  • modest blood pressure reduction – weak to moderate evidence from smaller studies
  • support for blood lipids – weak evidence
  • antioxidant effect – weak evidence for clinical benefit

Forms and how they differ

calyx tea

the most studied form

dried flower in capsules

convenient, anthocyanin content varies

extract

more concentrated, check the label dose

When to take it

Any time of day; the tea also works cold.

Pairs well with

Less salt, a potassium-rich diet (vegetables, legumes), exercise.

Do not combine / separate

Do not combine with blood-pressure medicines or diuretics without asking your doctor – effects may add up.

Watch out for

Not recommended during pregnancy and breastfeeding. With low blood pressure, diabetes, liver or kidney disease, or if you take medicines, consult your doctor.

Safety

As a tea it is considered safe in normal amounts; for supplements, do not exceed the label dose.

Practical tip

The tea is acidic – rinse your mouth with water afterwards to protect tooth enamel.
