Rooibos is valued for its multi-purpose remedial effects. It is an anti-viral, anti-allergy and anti-anxiety mediator. The plant is widely recommended as a supplementary medication while treating syphilis as it inhibits common inflammation (swelling and irritation) and reduces pain. However, the herb does not cure the disease. Rooibos is also effectual in treating mental disorders related to old age. In addition, preparations from the rooibos are frequently used as a alternate for milk for children who are inclined to suffer from stomach aches or colic. The herb is also said to have an anti-spasmodic action as it relieves cramps. Researches have shown that rooibos is also beneficial in reducing the hazards of heart disease and other conditions related to aging. Proof regarding the last two functions of the herb is increasing with each research or study on the herb. As mentioned above, rooibos has several remedial benefits. The therapeutic benefits of the herb for precise health conditions are listed below. Researches have shown that it is possible that rooibos impedes the release of histamine, an organic derivative of ammonia discharged by immune cells producing allergic reactions. In fact, the release of histamine is said to be liable for nasal congestion as well as stomach disorders during allergic effects and anxiety. Hence, this property of rooibos makes the herb immensely beneficial for everyone suffering from food allergies and respiratory allergies. The herb is also useful for smaller children, as the tea prepared with rooibos is known to be safe, mild and uncontaminated. A couple of studies conducted by Japanese scientists have found that rooibos is active against or combats the human immunodeficiency virus. The polysaccharide (a complex carbohydrate) amalgams present in rooibos thwarts the HIV from sticking to its intended or target cells in the body. In addition, the polysaccharides are more active and useful in dilutions that are totally uncontaminated or free from all toxicity to the vigorous human tissues. Interestingly, the tea prepared from rooibos is well-liked and accepted by all, including herbalist, common consumers as well as medical practitioners, in South Africa during bed time. This is possibly owing to the fact that the beverage prepared with the herb helps in stimulating sleep. Researches have shown that rooibos induces sleep straightforwardly by influencing the metabolism (the process by which ingested food is transformed into energy) of acetylcholine (a substance known to be a transmitter of nerve impulses) in the brain and thwarting the disproportionate discharge of neurons responsible for wakefulness. In some other way, rooibos provokes sleepiness by obstructing the reactions of the hormones that lead to pain and irritation or inflammation. It has been observed that rooibos is useful in curing insomnia, which is caused by drugs for Alzheimer's disease. However, here is a word of caution. The tea prepared with rooibos should be used for this purpose only after consultation and consent of the physician.
Rooibos is available in the market in tea form and has similarities with the black tea. Akin to black tea, rooibos too slows down the absorption of iron from the consumed food. However, rooibos is less effective than the black tea in soaking up iron from the ingested food. Hence, people suffering from deficiency of iron and related diseases should try to avoid drinking the rooibos as well as black tea. Drinking any of the two beverages may be detrimental for their health as they are likely to further bring down the iron content in their system.
