Astragalus Root Extract Health Benefits

Astragalus is an herb traditionally used in Chinese medicine. The dried root of this herb is used in either tincture or capsule form. Astragalus is both an adaptogen, meaning it can help the body adapt to various stresses, and an antioxidant, meaning it can help the body fight free radicals. Because astragalus is often used in conjunction with other herbs, it has been difficult for researchers to pinpoint the exact benefits of the herb alone. There have been some research studies, however, that show that astragalus root extract may be beneficial to enhance the immune system, reduce chemotherapy side effects and reduce fatigue in athletes.

Immune System Enhancement

According to the Sloane-Kettering Cancer Center, "Laboratory studies and some clinical trials suggest that astragalus stimulates certain parts of the immune system." Certain immune cells, such as monocytes and lymphocytes, help the body fight off viruses. The action of these cells may be increased by astragalus, therefore boosting the immune system. According to Mark Stengler, N.D., astragalus may also help the body secrete a chemical called interferon, which wards off the replication of viruses. Additionally, astragalus may increase the activity of natural killer cells. These cells can destroy both cancer cells and viruses.

Reduction of Chemotherapy Side Effects

Astragalus was studied as a treatment for patients with immune systems suppressed as a result of chemotherapy. According to the University of Maryland Medical Center, "In these studies, astragalus supplements have been shown to speed recovery and extend life expectancy." Astragalus has also been shown in animal studies to reverse the immune suppression that is a side effect of some chemotherapy drugs.

Reduction of Fatigue in Athletes

Herbal extracts containing astragalus may help athletes utilize oxygen, thereby reducing their fatigue. Because astragalus is an adaptogen, it can also help the body adapt to the physical stress brought on by exercise.

Other Uses

Astragalus root extract may also be beneficial for diabetes, AIDS and asthma. Further research studies are needed in these areas. In traditional Chinese medicine, astragalus root extract is also used for heart conditions, but it is usually used with other herbs so further research is also needed in this area to determine whether the herbs are beneficial when used separately.
