Triple Punch

Three botanicals combine to knock out infectious microbes.

As any student of the sweet science could tell you, boxing is more than just two sweaty guys pummeling each other mercilessly. The sport requires a set of highly refined skills, including the ability to throw punches in combination—a left jab followed by a right uppercut, for example.

In the same fashion, your immune system fends off infections with a combination of cells and chemicals designed to put harmful microbes on the ropes. Sometimes, however, even the best fighter meets a fierce opponent. That’s where natural immune boosters come in; like a boxer’s cornermen, they get their man ready for the next round. And if you’re that boxer, you want a team of top-notch assistants—such as arabinogalactan, olive leaf and andrographis—which can aid your immunity by attacking the problem from different angles.

Tough Defender

Your immune system possesses an arsenal of punches to match that of any ring champion. The basic unit of immunity is the white blood cell (WBC). Some, such as macrophages and neutrophils, are big cells that gobble up microbes. Other, smaller cells are known as lymphocytes. They include natural killer (NK) cells, tiny but ferocious predators; B cells, which secrete proteins called antibodies; and T cells, which become sensitized to individual immune threats.

Antibodies are only one of several classes of chemicals produced by the immune system. One of the largest is the interferon group. As the name implies, these substances help keep viruses from multiplying.

Botanical Cornermen

The fact that colds, influenza and other infections develop despite the immune system’s best efforts means that immunity doesn’t win every bout. That’s where botanical immune boosters come in; these natural compounds have shown a remarkable ability to help the immune response stay in fighting trim.

Healthy digestion helps strengthen all bodily systems, including the immune system. A fiber taken from the Western larch (Larix occidentalis) called arabinogalactan (ARA) feeds the friendly probiotic bacteria that call the intestines home, helping to shut out hostile germs. What’s more, ARA boosts NK cell activity and stimulates phagocytosis, the process by which large WBCs “eat” microbes.

Olive leaf—from the same tree that produces the beloved fruit—has been used since antiquity to reduce fevers. Today, scientists have isolated a substance called oleuropein from olive leaf that has shown an ability to overcome many fever-causing micro-organisms, including the viruses responsible for colds and the flu. In one study, olive leaf extract reduced a virus’s ability to induce infection by 30% (Antiviral Research 6/05). Like ARA, this extract spurs phagocytosis; it also neutralizes the sort of free radical damage that can harm WBCs.

Andrographis paniculata is an herb credited with helping to stop the spread of influenza during an Indian epidemic in 1919. Its key components, the andrographolides, have been found to boost WBC production and effectiveness, and to promote interferon release. No wonder andrographis has been found to reduce upper respiratory symptoms (Planta Medica 4/04).

Your best bet is to look for whole-herb products standardized to the key chemical compounds, which helps ensure consistent potency. Extended-release forms allow for longer-lasting benefits.
Getting the better of bacteria, viruses and other maulers can be a difficult fight. But with ARA, olive leaf and andrographis in your corner, you can be an immunity champ.
