The herbal tea made from rooibos (pronounced Roy-Boss) has been a popular drink in Southern Africa for generations. The plant, Aspalathus linearis, is grown only in a small area in the Western Cape province of South Africa, but during recent years rooibos has become popular in other parts of the world as well.
There are two varieties of rooibos tea. One is referred to as red rooibos and the other is green rooibos. Typically, rooibos leaves are oxidized before they are used to make red rooibos tea. This process, gives them the familiar reddish-brown color and the slightly sweet taste. An alternative treatment of the leaves and twigs does not include the fermentation or oxidation step and produces what is referred to as green rooibos. The tea made from unfermented rooibos has a yellow tan color. The green rooibos tea possesses a milder taste.
Rooibos tea is a concentrated source of antioxidants and flavonoids. In fact, Rooibos tea has been found to have as much as 50 times more Superoxide Dismutase (SOD) than Green Tea. It also has other antioxidants not found in other teas like aspalathin and nothofagin. It is naturally mineral rich, caffeine free and has low tannin levels compared to black and green teas.
Drinking organic green rooibos tea has number of health benefits. Traditional medicinal uses of rooibos in South Africa include alleviating nervous tension, infantile colic, allergies, asthma and digestive problems. When applied externally rooibos can be helpful for a number of skin irritations like itchy skin, eczema, dermatitis, sunburns, diaper rash, acne and rosacea. The alpha hydroxy acid and zinc contained in Green Rooibos Tea promotes healthy, smooth skin.
Studies suggest rooibos has potent antioxidant, immune-modulating and chemopreventive effects. In addition, green rooibos tea has not been found to have any adverse effects. In another study normal healthy rats given rooibos tea instead of water had significantly higher serum superoxide dismutase (SOD) levels than the control rats. They also had less DNA damage and accumulate significantly less aging damage in the brain than rats given water. In fact, the 24-month old rats given rooibos tea for most of their lives had brains similar to young 5-week-old rats. Futhermore, when the rats were given dextran sodium sulfate to induce colitis, the rooibos group had higher SOD levels, and the drop in hemoglobin levels seen in the control group was prevented. Thus, rooibos tea seems to be anti-inflammatory and have the potential to prevent DNA damage.
Due to the effects of rooibos on vasodilation and vasoconstriction, angiotensin I-converting enzyme (ACE) inhibitors and nitric oxide (NO) it has been used to treat conditions such as high blood pressure and heart failure. In one study, the effect of green tea, black tea and rooibos tea on ACE and NO was compared in healthy human volunteers. None of the three had a marked effect on NO concentration, but both green tea and rooibos tea inhibited ACE activity, suggesting that they have cardiovascular benefits.
Rooibos tea may help with diabetes as well. In a study on mice with type 2 diabetes, aslapathin suppresses the increase in fasting blood glucose levels. It also improves glucose tolerance, apparently through stimulating glucose uptake in muscle tissues and insulin secretion from the pancreas. So drinking rooibos tea during a meal may not be a bad idea.
Rooibos tea also has therapeutic potential for respiratory ailments. According to a study on rats, in addition to lowering blood pressure, rooibos tea is both a bronchodilator and an antispasmodic. This helps explain why rooibos tea is commonly used for gastrointestinal and respiratory problems. The flavonoid chrysoeriol seems to be mainly responsible for the bronchodilator and antispasmodic effect.
Unoxidised green rooibos tea contains more than twice the flavonoids as the oxidized red rooibos tea and 10 times the aspalathin and nothofagin. In the studies that have directly compared the two, the unoxidised green rooibos seems to generally come out on top. For example, unoxidised green rooibos tea seems to protect rats from liver cancer more effectively than the oxidized green rooibos tea.
