Astragalus root:
This root was originally used for stimulation of various systems of the body.

The immune system, by increasing the production of T-cells, was the first focus then discovered valuable ingredients that could be used as a dieuretic and for dialating of the blood vessels and for treating symptoms of respiratory infections and congestion.  Because of these findings it also claims to be useful in preventing colds. 

 I have to add, that very little studies have been done for it's anti-viral prevention.

Little study has been done with this herb for preventing heart diseases, but because it is  known for it's dieuretic abilities and lowering blood pressure, it is helpful in treating heart disease symptoms.

Caution should be taken with people suffering from some diseases such as M.S.(multiple sclerosis), chron's or any other bowel disorder.

The same caution should be taken with patients suffering from diabetes or systemic lupus, (connective disease).  As in all products taken to improve one's health, consulting with a qualified Physician should be a first consideration.

Safety for it's use, by pregnant or nursing women, has produced no result to date.

Any Prescribed drugs given for suppressing the immune system by a physician, should not consider adding   to their daily regime, any Astragalus.
