Astragalus herb could be helpful in some cases of aplastic anemia, congestive heart failure, and improving the immune system. For more astragalus information.

Chronic aplastic anemia
Clinical study on effect of Astragalus Injection and its immuno-regulation action in treating chronic aplastic anemia.
Chin J Integr Med. 2007 June. TCM Hospital of Langfang City, Chinese Hemopathic Therapeutic Center of TCM, Hebei, 065000, China.
To observe the clinical effect of Astragalus Injection and its immuno-regulatory action in treating chronic aplastic anemia. Sixty patients with chronic aplastic anemia were randomly assigned to two groups equally, both were treated with Stanozolol three times a day, 2 mg each time through oral intake, but astragalus injection was given additionally to the patients in the treated group once a day via intravenous dripping. All were treated for 15 days as one therapeutic course and the whole medication lasted for more than 4 months totally, with follow-up adopted.  Astragalus could promote the recovery of hemopoietic function, which might be through improving T-lymphocyte subsets and reducing the release of negative regulatory factors such as TNF-alpha and IL-2 to alleviate the inhibition on hemopoietic function.

Congestive heart failure
Astragalus has protective effect on ischemia/reperfusion injury. May be helpful in congestive heart failure.

Study on effect of Astragalus injection in treating congestive heart failure.
Zhou ZL, Yu P.Third People's Hospital, Hangzhou 310009.
To observe the clinical efficacy and side-effects of Astragalus Injection in treating congestive heart failure (CHF). Eighty-three patients of CHF with heart function of II-IV grade assessed by NYHA (New York Heart Association) classification were randomly divided into 2 groups. The 42 patients in the treated group were treated with AI 40 ml (equivalent to 80 g crude drug) by adding in 5% glucose solution 500 ml for intravenous dripping, once a day and the 41 patients in the control group were treated by nitrolingual injection 15 mg by adding in 5% glucose solution 500 ml for intravenous dripping once a day. The therapeutic course in both groups was 2 weeks and the patients were followed-up for 1-6 months. The clinical heart function improvement rate and the total effective rate in the treated group after 1 month treatment were 26% and 78%, and after 6 months were 34% and 81% respectively, which were superior to those in the control group significantly. The levels of left ventricular ejection fraction (LVEF), fractional shortening of left ventricular short axis, the ratio of maximum blood flow between the advanced and early atrial systole, stroke volume, cardiac output and the cardiac index were all improved in both groups, but better improvement was shown in the treated group. Follow-up study showed that the incidence of cardiac event was lower in the treated group than that in the control group. Astragalus injection can be took as one of the important auxiliary drugs for treatment of congestive heart failure especially in severe cases.

Immune system
Astragalus has been shown to enhance certain aspects of the immune system.
