Summary: Astragalus is a superior tonic herb with its use dating back over 4000
years. Since that time it has been one of the most popular herbs in China. It is
commonly added to soups to create a nourishing tonic meal. It is considered a
highly protective herb that promotes longevity. It is a warm, gentle, yet strong tonic
that can be used by the young and old. Almost anyone would benefit from the daily
consumption of astragalus.
It increases the qi of the lungs, strengthens the spleen and digestion, and helps
build and circulate the blood. It increases rising, upright qi, thus helping to hold
organs in their proper place. In chinese medicine there is a protective field of
energy called the "Wei Qi" that circulates under the surface of the body. It is an
adaptive energy that protects us from unfriendly enviromental invasions such as
cold, wind, dampness, and heat. Astragalus helps strengthen and tonify this
energy. It can help protect those people who easily catch a cold from the invasion
of coldness and wind.
Astragalus helps regulate the utilization of water, helping relieve edema or
stopping spontaneous sweating due to We Qi (defensive Qi) deficiency. It has
tissue regenerating and anti-inflammatory abilities which make it useful for
healing ulcers and external sores.
It also has powerful, broad spectrum effects on the immune system. Studies have
shown that astragalus protects, stimulates, and activates the production of white
blood cells and reduces suppressor T-cell activity. It increases T-helper cell activity
and natural killer cell cytotoxicity. It also induces the production of interferons.
Astragalus increases the number of stem cells in bone marrow and lymph tissue,
triggering immune cells to a heightened state. Research has clearly shown that
people who are undergoing radiation and chemotherapy have an improved
immune response using astragalus. It is commonly used in China for this
purpose. Astragalus replenishes vital energy and decreases adverse side effects
associated with these treatments; it protects white blood cells from destruction,
protects adrenal cortical function, and helps relieve gastrointestinal toxicity. It helps
people stay strong and recover better. In a study conducted by the University of
Texas Medical Center, researchers compared damaged immune cells from
cancer patients to healthy cells. Astragalus extracts were found to completely
restore the function of the cancer patients damaged immune cells, and in some
cases surpass the health and activity of the cells from healthy individuals.
Astragalus protects the liver against toxins and is used against chronic hepatitis.
Another study showed astragalus to inhibit the growth of tumor cells in mice. In
culture, it increases the lifespan of human cells.
Astragalus is also a heart tonic. It has been shown to protect the heart from
damage due to a heart attack or oxygen deprivation. It can also protect against damage from heart infections.
Science has shown that astragalus can help prevent colds or cut their duration in half.
