Astragalus is a leguminous plant commonly known as milk vetch. There are hundreds of different species of Astragalus around; some called locoweed in North America because they produce a kind of potentially fatal intoxication in grazing cattle known as locoism. But the medicinal herb is a Chinese native called Astragalus membranaceus, whose dried root and root extract are very popular in Chinese Medicine. Another species A. mongholicus is also used medicinally.
Several groups of active phytochemicals such as flavonoids, saponins, and polysaccharides are credited with the wide-ranging medicinal properties of this herb. Flavonoids have antioxidant properties that make them useful in reducing oxidative stress and reducing the risk of heart disease and cancer due to free radical damage. They are also involved in cell signaling.
Saponins are so named because of their soap-like foaming nature. They have a cholesterol lowering ability and are also known to improve the immune system. Many plants derived saponins are experimentally used in the treatment of cancer. Polysaccharides exhibit anti-microbial and anti-inflammatory properties.
Astragalus is now widely available and used as an adaptogenic herb for promoting general health and longevity and to treat specific disease conditions. The roots of Astragalus are harvested from plants that are 4-years old or older. It is available in the form of dried whole root, dried sliced root, root powder, capsules, and liquid extracts.

Health Benefit
1. Boosting the immune system
The immune system boosting property of Astragalus was what made it popular as an herb for general health in Chinese Medicine. Regular use of the herb protects against many diseases and seasonal infections.
Studies have revealed that Astragalus extract increases immune cell function, mainly by activating and regulating T-cells that are central to immune function. These cells are engaged in identifying foreign antigens and destroying abnormal cancer cells and virus-infected cells. Another property of T-cells is that they carry the memory of these antigens and offer continuing protection long after an infection is resolved.
Astragalus is used for treating hepatitis, where it displays an interferon-like action on hepatitis B infection. When used in the management of HIV infection, it delays the progress of the disease into AIDS. Marked increase in macrophages is observed following the administration of Astragalus, which explains, at least partly, the excellent immune boosting action of this herb.

2. Anti-inflammatory property
Inflammation is the body's response to injuries and infections, and it may have some beneficial role in effecting recovery. However, this immune response often goes overboard, causing unnecessary pain and swelling, and sometimes precipitating irreversible damage. The anti-inflammatory action of Astragalus can promote faster healing of wounds and resolve infections quickly by limiting the inflammatory response.
Chronic Inflammation is the underlying cause of many debilitating disease conditions, including heart disease, diabetes, and arthritis. The polysaccharides in Astragalus have been shown time and again to reduce markers of inflammation in in vitro and in vivo studies, but the exact anti-inflammatory mechanism is poorly understood. Nevertheless, taking Astragalus regularly as an herbal tea or using its extract can reduce the severity of inflammatory conditions like arthritis and eczema and protect you from the damages caused by chronic inflammation.

3.Protecting against cold and flu and other respiratory diseases
This effect could be regarded as a natural fallout of the immune boosting property of Astragalus. The Chinese have used this herb for thousands of years to protect them from seasonal ailments like cold and flu.
Since the viruses causing cold and flu continually undergo mutation to form new and more virulent strains, long-term protection is nearly impossible, even with the latest vaccines at our disposal. However, the wide-ranging antiviral property of Astragalus seems to be capable of handling these challenges. In fact, it is considered even more effective than the popular Echinacea formulations in offering cold and flu protection. It might be worthwhile taking Astragalus tea or extract a few weeks prior to the onset of flu season as the Chinese do.
The antibacterial effect of Astragalus may help prevent secondary infections in the lungs and respiratory tract, such as bronchitis and pneumonia, that often follow seasonal viral infections.
