Your Nutrients for Immunity

Your Nutrients for Immunity

As we discussed in chapter 5, certain nutrients exert a profound effect on immune
functioning. Recall that vitamins D, C, and A, as well as the carotenoid family
(including beta-carotene) and the minerals selenium, zinc, and magnesium, are
protectors of immunity and overall cellular health. Chapter 5 lists food sources of
these critical nutrients and offers advice on how to choose supplements that contain
healthy forms of them.

Noteworthy Herbs for Immune Balance

Literally hundreds of herbs have been examined for both immune-boosting and
cancer-protective properties. While space is limited here, an invaluable resource for
learning about herbs and cancer in brilliant detail is herbalist Donald Yance’s book
Herbal Medicine, Healing, and Cancer (1999). According to Yance, the essential
beauty of herbs is that they provide a concentrated assortment of phytonutrients that
balance and heal injured cells and tissue. They signal the immune system to be more
precise in its surveillance and deployment missions. The herbs described next are
rich in trace minerals and protective bioflavonoids that send extra healing energy to
weary circulating cell defenders.

ASTRAGALUS

This herb is used for its immune-enhancing properties and to bolster white
blood cell counts. In long-established studies from the NCI and other leading U.S.
cancer institutes, astragalus has been shown to strengthen the immune system (Sun
et. al 1983). Based on these studies, it is evident that astragalus does not attack cancer
directly, but instead strengthens the body’s immune system.

CAT’S CLAW (UNO DE GATO)

Cat’s claw is a woody vine native to the South American rain forest whose bark
has been used traditionally for its immune-enhancing characteristics. While human
trials have not yet been conducted, in vitro studies have indicated that alkaloids from
the plant intensify the rate of phagocytosis (the process of engulfing and destroying
foreign particles) and fuel the production of interleukin, an important substance
produced by white blood cells to help orchestrate incoming attacks on invaders
(Lemaire et al. 1999).

A CAUTIONARY NOTE ABOUT HERBS

Herbs are powerful, complex remedies that contain hundreds of compounds
working together synergistically. For this reason, we suggest that you consult with a
seasoned herbal practitioner before embarking on a program of herbal
supplementation. Be sure to describe your regimen with other practitioners you are
seeing, and be alert for potential interactions.
