AHPA has released a botanical safety assessment of rooibos as a new entry in the Botanical Safety Handbook 2nd Ed. online version.
Rooibos is a botanical commonly consumed as a tea made from the leaves of Aspalathus linearis, a shrub native to South Africa. It is consumed in both red (fermented) and green (unfermented) forms. In the fermented form it is also referred to as “red tea” or “red bush tea.” Historically consumption of rooibos was limited to its native South Africa, but in recent years it has quickly grown in popularity and is widely available internationally as an ingredient in herbal teas. Rooibos contains high amounts of antioxidants, no caffeine, and is low in tannins compared to other teas, so consumers may choose it for these properties.
The AHPA safety assessment concluded the following for rooibos:
- It has a history of safe traditional use as a beverage;
- It is not known to interact with drugs or supplements at typical levels of consumption;
- No case reports of significant adverse events with a high probability of causality were identified;
- No significant adverse events were observed or reported in clinical trials;
- No concerns for use during pregnancy or lactation were identified; and
- It contains no innately toxic constituents.
Scientific articles reviewed in the development of the rooibos entry included case reports; clinical trials; human, animal and in vitro pharmacological studies; and toxicity studies.
