One of the key uses for astragalus, in alternative medicine, is to improve immune function. Although evidence is needed, one of the ways astragalus is said to work is by increasing the production of immune cells. It may also have mild antiviral activity and help with the prevention of colds. There's little evidence from human studies, however, on the effectiveness of astragalus as an antiviral.

Astragalus is also used for various heart conditions. It may have a diuretic effect which would lower blood pressure and it may cause blood vessels to relax. It hasn't been explored in human studies, so it shouldn't be used as a replacement for conventional care.

There is limited evidence that herbal formulas containing astragalus may be able to help boost strength and stamina in athletes. Additionally, it may help combat fatigue in cancer patients.

Astragalus is an essential herb for your immune system and is well known to help fight viral & bacteria infections, inflammation, and even cancer. It quickly and effectively strengthens the immune system and increases white blood count which makes it highly beneficial for warding off and reducing the effects of colds, flu, respiratory ailments, herpes, shingles, and immune system disorders. 

Astragalus is also excellent at promoting circulation and helping to reduce chest pains, lower high blood pressure, and prevent cardiovascular problems such as arrhythmia and heart disease. Astragalus is great for managing diabetes and helping to lower blood sugar. It is highly beneficial for the liver and kidneys and has been shown to help those suffering from hepatitis, chronic nephritis, jaundice, and renal disease.

It can also help to lower stomach acidity which helps those suffering from ulcers and indigestion. It helps to prevent fats from being absorbed from the intestines which promotes healthy waste elimination. Astragalus has also been found to help boost metabolism and increase energy and endurance levels which ultimately can lead to substantial weight loss. 

Astragalus works well with conventional treatments and has even shown to be an effective complement to those undergoing chemotherapy and HIV/AIDS treatments. It has long been used as an anti-aging and longevity tonic that enhances all the systems of the body and promotes overall health and balance. Astragalus is commonly found online or at your local health food store in tincture, extract, capsule, or tea form.
