Astragalus belongs from the plant genus (genus is a rank like family, root, types and genus it comes in order) of about 3,000 species of herbs and small shrubs. It comes from the family of fabaceae commonly called bean, pea or bean family. It grows in moderate areas of the northern hemisphere.

Astragalus is understood by numerous names but typically referred to as milkvetch, huang qi, locoweed, goat thron etc., there are different types of astragalus as mentioned above however the most astragalus supplements consists of astragalus membranaceus. Astragalus is extremely well-known in china and asia due to its abundant use, it is discovered in china, mongolia and north korea. Its famous history shows that it has been used in china for more than 5000 years.

Astragalus is herbaceous perennial, it grows between 25 and 40 cm in height, it normally grows in grassy area and near mountain ridges; this herb needs ample of sunlight to cultivate, this plant is generally harvested after 4 to 5 years and the roots are gathered throughout spring or autumn. The roots of astragalus are sun dried and after that slashed for distribution. The color of these roots is yellow and has a sweet, damp taste with fibrous texture. (3 ).

Astragalus types

Astragalus, the biggest genus of herbaceous plants in the pea and bean family, consists of approximately 3,000 types distributed throughout europe, africa, asia and north and south america. These species are yearly or perennial, herbs or subshrubs with odd- or even-pinnate leaves. Their flowerheads of pea-like flowers are white through yellow and red to purple and blue. The fruit pods contain kidney-shaped seeds.

Hardly ever grown in gardens, astragalus types have many usages. Belief that astragalus enhances the quality of the milk of people and grazing animals triggers among the potential origins of the generic name, ‘star-milk’ (from the greek astron and gala). Another possible origin is from the greek significance ‘ankle-bone’, potentially a reference to the shape of the seeds or the roots. Astragalus types are used to deal with breathing infections and kidney illness, whilst astragalus mongholicus, an important herb in chinese medication, is thought to control the immune system. These associated claims of the restorative properties of astragalus are unsupported by strenuous proof. Some astragalus species are nevertheless poisonous.

Astragalus is undoubtedly useful in the form of gum tragacanth. This odourless, tasteless, thick compound, which is rich in polysaccharides, is extracted from the sap and roots of a number of types of middle eastern astragalus, especially astragalus tragacantha. There are records of making use of gum tragacanth as early as the third century bce, a longevity matched by its flexibility.

However, there are some species of astragalus you would not desire on your cake. These are the so-called ‘locoweeds’, which lead to neurological problems in animals that graze upon them. Many of these astralagus types accumulate high levels of harmful selenium from the soil. Other locoweeds produce the poisonous alkaloid swainsonine, although in some cases this alkaloid is produced by fungis living inside the plants, instead of the plants themselves. Selenium hyperaccumulation makes the genus beneficial in plant-based prospecting, a technique which utilizes plant populations to locate interesting mineral deposits. This can be accomplished simply by searching for the existence of ‘sign plants’, including certain astragalus types, or by taking samples of plant product and carrying out chemical analyses for selenium.

Nevertheless, other research studies in patients with cardiac arrest have actually failed to demonstrate any benefits for heart function.

In addition, some studies suggest that astragalus might lower symptoms of myocarditis, an inflammatory condition of the heart. Yet, findings are combined.


Though research findings are mixed, astragalus may assist improve heart function in clients with cardiac arrest and reduce symptoms of myocarditis.

Might minimize adverse effects of chemotherapy

Chemotherapy has numerous unfavorable adverse effects. According to some research studies, astragalus might assist reduce some of them.

For example, one scientific research study in people going through chemotherapy discovered that astragalus provided by iv lowered queasiness by 36%, throwing up by 50% and diarrhea by 59%.

Likewise, several other research studies have demonstrated advantages of the herb for nausea and throwing up in individuals undergoing chemotherapy for colon cancer.

  • Absence of new blood cells from bone marrow (aplastic anemia). Early research study reveals that giving astragalus intravenously (by iv) together with the steroid stanozolol improves signs and blood cell counts more than simply the steroid alone in individuals with aplastic anemia.
  • Asthma. Early research shows that taking a combination of astragalus, cordyceps, radix stemone (bai bu), bulbus fritillariae cirrhosae, and baikal skullcap by mouth for 6 months does not improve asthma symptoms or lung function in children with mild asthma.
  • Liver scarring (cirrhosis). Early research suggests that injecting a combination of astragalus and danshen in to the vein every day for up to 90 days might improve liver function in people with liver cirrhosis. It’s prematurely to know if the enhancement is due to astragalus, danshen, or the combination.
  • Vision problems in individuals with diabetes (retinopathy). Early research study recommends that taking herbal items containing astragalus for as much as 10 months may improve vision in some individuals with vision damage triggered by diabetes.
  • Hearing loss. Early research reveals that offering astragalus intravenously (by iv) daily for 10 days can improve hearing in people with sudden deafness or hearing loss triggered by extremely loud noise.
  • Hiv/aids. Evidence on the impacts of astragalus in people with hiv/aids is inconsistent. Individuals treated with a specific mix consisting of baikal skullcap root, glossy privet fruit, astragalus root, and eupolyphaga et polyphage (ailing granules) for 4 months show improvements in hiv/aids signs
  • And immune function. Nevertheless, taking a different combination including licorice, yin chen, white mulberry, astragalus, and safflower by mouth for 12 weeks does disappoint the same advantages.
  • Lung cancer. Platinum-based chemotherapy is used to treat a kind of lung cancer called non-small-cell lung cancer. Analysis of early research recommends that taking herbal products containing astragalus in addition to platinum-based chemotherapy can lower the danger of death in individuals with innovative non-small-cell lung cancer after one, two, and 3 years of treatment compared to platinum-based chemotherapy alone.
  • Menopausal symptoms. Early research suggests that taking 3-6 grams of a specific combination of astragalus and dong quai called dang gui buxue tang may lower hot flashes in menopausal females. However, lower dosages do not seem to be efficient.
  • Infection in the heart (myocarditis). A number of early research studies have used astragalus for the treatment of viral myocarditis, however outcomes are inconsistent. The best proof to date recommends that taking astragalus preparations in addition to traditional drugs for myocarditis can reduce the number of people with myocarditis who have abnormal heart beats. Nevertheless, taking astragalus appears to enhance only some but not all blood markers of heart damage.
