Herbs for boosting immunity
Echinacea
Also called purple coneflower, echinacea (pronounced ek ih NAY sha) has been shown to be effective in fighting the viruses that cause colds and flu. The remedy works best if you take it at the first sign of a sniffle or, better still, at the start of cold and flu season.
The tincture form seems to be most effective, perhaps because the liquid is readily absorbed by the lining of the mouth. The usual tincture dose is 3–4 ml three times daily but, because strengths vary from brand to brand, it is best to follow the label directions. For tablets or capsules, the usual dose is 300 mg three times a day.
Don’t take echinacea for longer than eight weeks. It works best when taken at the first sign of illness and continued for only a limited time. Echinacea stimulates your infection-fighting T-cells, but overuse can deplete your reserves and weaken your immune system.
Astragalus
Used for more than 2000 years in China, this herb is valued most for fighting colds, the flu and sinus infections because it prevents viruses from gaining a foothold in the respiratory system. It’s used to build up the immune system of people undergoing chemotherapy or radiation treatment. It may help lower blood pressure and prevent angina pain. Astragalus also acts as an antioxidant. The usual dose is 200 mg once or twice a day for three weeks, followed by a three-week break.
Maitake, shiitake and reishi mushrooms
Extracts of these medicinal mushrooms help bolster immunity. Capsules are available that contain all three varieties. Studies suggest that medicinal mushrooms may be powerful enough to help people with HIV infection and AIDS.
Reishi extracts also stimulate the production of a substance that kills cancer cells and studies have suggested it can improve survival rates in people with stomach, colon and lung cancer. Shiitake mushrooms may also help lower elevated cholesterol. Check the label for dosage information.
