An increasingly popular beverage, rooibos tea originates from the leaves and stems of the indigenous South African plant Aspalathus linearis. It has gained much attention for clinical purposes in the case of nervous tension, allergies (dermatitis), and various indigestive problems. Rooibos tea contains a large amount of flavonoids and acts as a potent antioxidant. In Africa, it has been used to treat malignancies and inflammatory disorders.

Rooibos (pronounced ROY-boss) is not a natural source of caffeine and is low in tannins. Rooibos tea may be preferred by people who can not tolerate either the caffeine effects or astringency of Camellia sinensis teas.

DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.

Side Effects and Warnings

Little evidence is available to describe the adverse effects of rooibos. Rooibos is likely safe when ingested as a tisane (herbal infusion) in food amounts. However, use cautiously in patients taking drugs or herbs metabolized by cytochrome P450 enzymes, as there is unclear evidence whether or not rooibos affects these enzymes.

Pregnancy and Breastfeeding

Rooibos is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
