Rooibos is also called redbush tea and sometimes just bush tea, although it is distinct from honeybush, a similar tea from the same region made out of a different plant, also a legume.
Rooibos has a distinctive flavor and aroma, often described as earthy and fruity; it is less bitter than most black tea, but is often described as being among the herbal teas that most closely resembles black tea. Like most herbal teas, it contains no caffeine.
Use in blending with teas, other herbs, and flavoringsRooibos is frequently used in herbal tea blends, often as a base to impart body or richness. We list herbal teas with rooibos as the dominant ingredient as flavored rooibos. Common ingredients or flavors for blending include vanilla and strawberry, as these blend well with the natural aroma of the herb. Less commonly, the herb can be scented with bergamot to produce a rooibos Earl Grey, or blended with spices to yield rooibos chai or spiced rooibos, a reference to masala chai. Rooibos is also frequently mixed with black, green, or other teas together with other herbal ingredients or flavorings; such blends are listed under miscellaneous blends.
Cultivation and production
All finished rooibos has a fine texture, owing to the very small needle-like leaves of the plant, although there is a range of grades with different coarseness. Higher grades have a higher ratio of leaf to stem.
More recently, however, people have begun to manufacture green rooibos, which is produced in a process similar to green tea, more similar to Japanese steamed green teas than Chinese pan-fired teas.
Impact of climate change and povertyEfforts to cultivate rooibos outside the small region where it grows have proved unsuccessful, as it is dependent on the region's unique climate, soils, and other components of the ecosystem. Rooibos production is being threatened by climate change, and many farmers of rooibos live and operate in extreme poverty, complicating measures to adapt to the changing climate.
Medicinal uses & health benefits of rooibos
Luteolin is an antioxidant
present in rooibos.
Rooibos is frequently promoted as having antioxidant activity comparable to that of tea; a study validated this for both green and red rooibos. The antioxidant activity of rooibos, has been shown in mice to protect against radiation damage, probably by luteolin and possibly other antioxidants neutralizing the free radicals formed by exposure to gamma rays.
In addition, rooibos is widely used in traditional medicine for respiratory ailments such as asthma. A study on rats found significant dose-dependent bronchodilatory effect, providing a sound basis for its use in treating respiratory conditions. Another study on rats found that rooibos provided significant protection against liver damage, in concentrations equivalent to that typically used when humans drink rooibos tea.
Topical use of rooibos in skin care products
Topical application of rooibos (such as its use in creams, cosmetics, and sunscreen) also shows some promise of health benefits. One study found that rooibos, honeybush and green tea, all had tumor-preventing properties in mouse skin, suggesting that these teas hold promise for preventing skin cancer. More recent work has uncovered likely mechanisms by which topical use of rooibos and honeybush reduce tumour promotion, inflammation, and oxidative stress.
