General Tonic:
 In China, it has long been used as a classic energy tonic and is considered to be superior to ginseng for young people. It is believed to warm and tone wei qi (a protective energy that circulates just beneath the skin), helping the body to adapt to external influences, especially to the cold. It raises immune resistance, improves physical endurance, and encourages the body systems to function correctly.
 By encouraging blood flow to the surface, the herb is effective in controlling night sweats, relieving fluid retention, and reducing thirstiness.

Anti-aging effect of astragalosides: 
 Aging is a natural phenomenon that has a common symptom; motor and memory dysfunction. Also,there are a lot of assumptions concerning senescence,such as free radical degeneration and immune system dysfunction.
 Astragalus is a kind of Chinese tonic herbs. Its active part is astragalosides (AST) and polysaccharides which are extracted from the root of Astragalus membranceus (Fisch) Bge. Previous studies from our laboratory showed that AST possessed an anti-aging effect, probably being related to its anti-oxidative properties. A pilot study from our laboratory demonstrated that AST had an immunomodulatory effect. However, the relationship of anti-aging effect of AST to immune response is unknown. The present study was therefore designed to investigate the anti-aging effect of AST and its relation with immunity, exploiting D-gal-induced senescent mice and the middle-aged mice.
 Some Scientists from China Rotating rod test and step-down type passive avoidance test were performed to determine the effects of AST on motor and memory of D-galactose (D-gal)-induced senescent mice and the middle-aged mice. The proliferative response of splenocytes induced by Con A or LPS, IL-2 production of splenocytes induced by ConA of D-gal-treated mice and the middle-aged mice were also measured.
 AST (40 mg;kg^-1;d^-1,ig, for 10 weeks) was found to ameliorate age-related alternations in both motor response and memory, enhance the deteriorated cellular immunity in D-gal-treated mice and the pre-aged (17-month-old) mice.
 Conclusion: AST has an anti-aging effect on D-gal-induced senescent mice and has the effect of delaying senility of the middle-aged mice, which was related to its improvement of brain function and immunomodulatory effects.

Astragalus Cardiovascular effects. 
 Some evidence mostly from case reports in humans and studies of laboratory animals does suggest that chemicals in astragalus may have other medical uses. It has been used to treat high blood pressure because it may have diuretic effects that promote the elimination of excess water from the body. It may also have other cardiovascular effects that may benefit individuals with heart failure. In addition, astragalus may protect kidney tissue from damage when blood flow to the kidneys is blocked and then re-started. One small study of patients with hepatitis C showed improvement after 6 months of treatment with astragalus. Although this possible effect is not understood completely, it is believed that astragalus may help to reduce the side effects of radiation and drug treatments for cancer. Small studies of animals show that astragalus may increase sperm production as well as its activity (motility). Much more research is needed before astragalus may be recommended for oral use to treat any of these conditions, however.
 It can strengthen the heart, obviously dilate peripheral, coronary, cerebral and intestinal vessels, and improve micro-circulation. The herb can rapidly but briefly reduce blood pressure, promote the development and maturity of blood cells, obviously induce diuresis (increased excretion of urine) and improve kidney funciton. It has anti-inflammatory, anti-bacterial, anti-viral and antiaging effects.
 Milk vetch root is a sweet tonic herb that stimulates the immune system and many organs of the body, whilst lowering blood pressure and blood sugar levels. It is particularly suited to young, physically active people, increasing stamina and endurance and improving resistance to the cold--indeed for younger people it is perhaps superior to ginseng in this respect.

Astragalus increase immune system:
 Taken internally, Astragalus is commonly used to strengthen the immune system, especially in such immuno-compromised individuals as those with HIV or during chemotherapy.
 Astragalus is the primary herb used in Chinese medicine to tone the immune system of the lungs. It is useful for conditions of immune deficiency that lead to spontaneous sweating. It is also used for spleen qi deficiency with symptoms of weak, low metabolism; edema; and prolapse of internal organs, as it raises the spleen yang and qi. It can be used for qi and blood deficiency caused by loss of blood or after childbirth.
 Astragalus contains numerous active compounds which bolster immunity. The polysaccharides seem to stimulate white blood cell production and spurs the activity of killer T cells, increasing the number of cells and the aggressiveness of their activity. Increased macrophage activity has been measured as lasting up to seventy-two hours.
 Astragalus increases the number of stem cells in the marrow and lymph tissues, stimulates their maturation into active immune cells, increases spleen activity, increases the release of antibodies, and boosts the production of hormonal messenger molecules that signal for virus destruction.
 Studies at the University of Texas Medical Center found that astragalus was able to restore completely the function of cancer patients compromised immune cells.
 Immune stimulation :Astragalus has been suggested as an immune system stimulant in preliminary laboratory and animal research, and in traditional accounts. Reliable human studies are lacking. High quality human research is necessary before a firm conclusion can be drawn. 

    Astragalus benefit liver and act as antibiotics.:
 Astragalus also increases production of interferon, a natural protein that stimulates production of other proteins that help prevent and fight viral infections.
 It protects the liver from a variety of liver toxins, including carbon tetrachloride and the anticancer compound stilbenemide.
 Chinese experiments indicated that the herb was able to protect against the absorption of toxic chemicals into the liver. Studies have shown that patients given the herb suffered less angina and had a greater improvement in the EKGs and other measurements than patients given such standard heart drugs as nifedipine. Chinese researchers report that the herb improves funtion of the heart's left ventricle after a heart attack, which they theorize may derive from the herb's antioxidant effects. Other Chinese researchers found heart-protective effects in people with Coxsackie B virus which can cause viral myocarditis. Staphylococcus aureus, Salmonella spp., and Proteus mirabilis.
 
 Liver protection:Several animal and human studies report that astragalus may protect the liver from damage related to toxins or hepatitis B and C. Overall, this research has been poorly designed and reported. Astragalus alone has not been well evaluated. Better quality research is necessary before a conclusion can be drawn.
