1) Live in a warmer climate. Unfortunately, this is the number one and best preventive defense against the cold virus, but not much consolation to those living far from equator. Sorry Minnesota.
2) Taking the sunshine vitamin is shown to reduce the risk of flu to a third of what it would otherwise be. The correct daily dose of vitamin D3 for adults is approximately 5,000 IU/day, not the 200 to 600 IU recommended by the Institute of Medicine, the National Institutes of Medicine and the FDA. You may even be shocked to know that there are many physicians in both Canada and the United States who prescribe as much as 50,000 IU of vitamin D daily as a treatment for a long list of chronic diseases.
3) Stay away from sucrose. Its ability to impair and depress the immune system is unparalleled.
4) Stay away from all vaccines, especially the flu shot. Flu vaccines still contain mercury and only work to depress the immune system. Regardless of what statistics your government has released, the actual chances of a flu vaccine preventing the flu are less than 4 percent.
5) Use Virus-Fighting Herbs. Some of the best immune stimulants are anti-viral herbs. Virus-fighting herbs include purple coneflower, pot marigold and black elder. Other important antiviral herbs include yarrow herb (Achillea millefolium), hyssop herb (Hyssopus officinalis), lemon balm herb (Melissa officinalis), St. Johnswort (Hypericum perforatum) marjoram herb (Origanum majorana), oregano herb (Origanum vulgare), heal-all herb (Prunella vulgaris), rosemary herb (Rosmarinus officinalis) and blue vervain herb (Verbena hastata). It is important to begin taking the herbs as soon as you think you are getting sick. Take your formulation four to six times per day until you are better.
6) Use Deep Acting Immune Tonics. Another group of herbs that help to improve and optimize immune function are the immune tonics. These herbs are deeper acting than immune stimulants, but take longer to work. They include North American ginseng root (Panax quinquefolius), lacquered polypore or reishi mushroom (Ganoderma lucidum), artist’s conk (Ganoderma applanatum), Chinese milkvetch root (Astragalus membranaceus) and Siberian ginseng root (Eleutherococcus senticosus). Combine two or three immune tonics and take them three to four times per day for two to three months. Immune tonics are not suitable for treating infections in progress. They are used for preventive purposes or to optimize immune function and work best after first doing several cycles of immune stimulants.
There are also many other important antioxidant nutrients that support immune functioning. These include the carotenes, flavonoids and other polyphenols such as those found in green tea, grape seed, pine bark and various berry extracts. The best food sources of immune-enhancing nutrients are fresh fruits, vegetables, and mushrooms.
