The very name of this tea suggests that it came from a faraway time and
place. Actually it did. Grown high in the mountains of South Africa, it beckons
us back to a world without polluted air or soils. Like other plants growing this
way, rooibos (pronounced "royboss") is extravagantly rich in
naturally-occurring nutrients. At a particular point in the plant's ripening
process, the leaves develop a reddish brown color, explaining why this
increasingly popular beverage is also referred to as redbush tea. New to
Americans, the health-giving properties of rooibos tea have been scientifically
documented done in Japan and South Africa. Studies show that the tea relieves
insomnia, nervous tension, mild depression, stomach cramps (including colic),
constipation, and allergic symptoms (even those caused by hay fever and asthma).
It can also ease itching and skin irritations, thereby also offering eczema and
acne victims welcome deliverance from misery. Here are some other benefits:
What's in Rooibos tea that makes it so special?
First, let's talk about what's not in it.
Rooibos tea, unlike other uplifting or "entertainment" beverages,
has no caffeine. According to new studies done at Duke University, the caffeine
in your morning coffee is confirmed to put you in a state of sustained stress,
affecting both blood pressure and heart rate all through the day.
Women who are heavy caffeine drinkers are twice as likely as caffeine abstainers to have short menstrual cycles. So instead of having a period every 28 days, the time between cycles may be reduced to 24 days or less. And maternal coffee consumption is related to preterm delivery and low birthweight.
Iron in the body is reduced by about one-third in tea drinkers. The culprit? Tannin. Tannins (commonly referred to as tannic acid) are the active ingredient in black tea. They can also decrease food intake, growth rate, food efficiency, and protein digestibility. Foods rich in tannins are considered to be of low nutritional value. A study was carried out to determine if rooibos tea has a deleterious effect on iron absorption similar to that of ordinary tea. Result: Rooibos tea had no significant effect on iron absorption. The limited tannin in this tea also translates to a sweet taste, unlike conventional teas that are bitter mainly because of tannin content.
Now here’s the good stuff:
As our environment has grown more toxic, we have a greatly reduced access to natural antioxidants (vitamin E, vitamin C, bioflavonoids, carotene, and a host of other less well-known chemicals). So it's not only oxidative damage but also antioxidant deficiency that impacts on a wide range of human diseases -- from cancer to viral infections to circulatory disease. Both are primary reasons why our bodies eventually run out of new cells to replace the older ones that eventually fail, in spite of our built-in safeguards. Several studies show that rooibos tea contains highly defensive natural antioxidants. Equally exciting, rooibos tea has been validated to be anti-aging, particularly for preventing age-related byproducts of oxidation in the brain. The tea was also able to inhibit the cancer-causing effect of X-rays in test animals. Carcinogenic transformation of cells was reduced with increased concentration of rooibos extract. (Green tea, by the way, does not have this toxic transformation-suppressing capacity.)
Rooibos tea is rich in this very powerful family of antioxidants. Its major flavonoid is aspalathin -- found only in rooibos tea. Flavonoid-containing herbs have traditionally been used to treat leg cramps and various skin and circulatory disorders. Flavonoids may also have anti-inflammatory and anti-allergic properties, explaining the benefit claimed for rooibos skin lotions and cosmetic products. Superoxide dismutase (SOD). SOD is an enzyme that protects against oxidant-induced damage, functioning as a prime scavenger of free radicals. It has the capability of preventing fats from changing into harmful lipid peroxide. Plus it has anti-inflammatory actions and it is easily digested.
Rooibos tea secretes a family of unusual oligosaccharides. These are compounds made up of small numbers of simple sugars. The most dramatic news about rooibos tea is that studies from Japan demonstrate safe, anti-HIV activity from the oligosaccharides contained in it. Oligosaccharides are involved in the mechanism for viral binding of T-cells, immune soldiers that know how to keep dangerous attackers at bay.

How to use rooibos tea
Rooibos is excellent hot or cold, in water or juice -- with or without honey or lemon, and can be consumed in unlimited quantities throughout the day. It can be used as a base for punch, cocktails, soups, stews, marinades, or sauces -- adding color, flavor, and aroma (plus antioxidants and other nutrients!). It can replace liquids called for in recipes. Rooibos doesn’t deteriorate in taste or appearance when refrigerated or reheated. Some friends discovered that it's a good meat tenderizer. And here’s a rooibos dessert: Baked apple, topped with cinnamon, cloves, a dash of butter, and hot rooibos tea.
