Overview

Rooibos is a fragrant, caffeine-free tea. It is made from the leaves and stems of a tree called Aspalathus linearis. This tree grows in South Africa, where rooibos tea is the national drink.

Rooibos is used for hay fever, preventing cancer, preventing heart disease, indigestion (dyspepsia), and other conditions, but there is no good scientific evidence to support these uses.

How does it work ?

Rooibos contains chemicals that might protect the heart and might also prevent age-related changes in the brain.

Uses & Effectiveness ?

Insufficient Evidence for

  • Hay fever.
  • Anxiety.
  • Heart disease.
  • Indigestion (dyspepsia).
  • HIV/AIDS.
  • Preventing cancer.
  • Preventing decline in memory and thinking skills that occurs normally with age.
