Frequently Asked Questions About Astragalus

What is Astragalus?

Astragalus is a herb that’s been used in traditional Chinese medicine for millennia. There are thousands of species of the plant, but only two are still commonly used today – Astragalus membranaceus and Astragalus mongholicus.

Astragalus is also known as milkvetch or huáng qí. Several cultures have used it traditionally, believing it to promote long life, fight fatigue, reduce allergies and more.

Nowadays, astragalus is still commonly used in supplement form. The root of the plant is powdered and included in various supplements.

The plant contains several active compounds that are thought to contribute to its potential benefits (1). For example, the polysaccharides found in astragalus root are thought to contribute to the plant’s effects on the immune system (2).

Overall, this is an herb that needs more research – but the clinical studies we do already have point to several potential uses for astragalus.

What Are the Uses & Benefits of Astragalus?

Astragalus is primarily used for immune health, heart function, allergies and more. Some benefits are more proven than others. Some primary potential uses for astragalus include:

  • Immune Health – Astragalus may help to improve the health of your immune system. Some evidence from clinical trials has shown that astragalus may increase the natural production of white blood cells (3) which are essential for the body to ward off potential illness. Some evidence suggests that astragalus may also help fight viral infection, including hepatitis and the common cold (4, 5). More research is needed.
  • Heart Health – Astragalus supplementation may help to improve heart function, particularly in individuals with existing heart conditions. It may help to increase blood flow from your heart while widening blood vessels (6). In one study, patients with heart failure who were given astragalus daily showed greater improvements in heart function when compared with the control group (7). With that said, some similar studies have shown no benefit (8) – so more research is needed.
  • Blood Sugar – Astragalus is commonly used in China to help manage blood sugar levels in individuals with diabetes (9, 10). One study of people with type 2 diabetes showed that taking astragalus daily helped improve blood sugar levels after meals and fasting (11). Animal studies have backed up these findings, showing that astragalus helped to improve sugar metabolism and lower blood sugar levels (12). More research is needed, but clinical data thus far is positive.
  • Kidney Health – Astragalus is thought to potentially support kidney health. It may help prevent infections in individuals with impaired kidney functions (13). It has also been shown to improve proteinuria, a common condition in individuals with kidney disease (14). More research is needed.
  • Other Benefits – There are other potential benefits of astragalus root. Some studies have shown that it may help reduce fatigue in individuals with chronic fatigue syndrome (15). One study found that astragalus supplements may help reduce the intensity of seasonal allergies (16). Test-tube studies have shown potential anti-cancer effects (17, 18), but research is limited. All of these potential benefits require more research.

How Do I Take Astragalus?

Astragalus can be taken daily, according to the guidelines set forth by the product manufacturer. notes that due to the potential for differences in potency between manufacturers, it’s difficult to set a standard dosage quantity, and you should simply follow the instructions included with the supplement.

Many manufacturers of top astragalus supplements recommend that you take two servings per day, split up in morning and evening. This is not strictly necessary but may be beneficial.

Astragalus can be taken with or without food, but some people find that it can cause minor stomach irritation on an empty stomach. If you experience this, try taking your dose with or shortly after a meal.

Are There Any Side Effects?

Astragalus appears to be well tolerated for most people. Most people do not experience any noteworthy side effects. That said, minor side effects are possible.

The most commonly reported side effects in research studies include stomach upset, nausea, diarrhea, rash, runny nose, and itchiness (19, 20).

Astragalus can also be given by IV, but this should only be done under medical supervision as the potential for serious side effects is higher (21).

Although astragalus is typically well-tolerated, certain groups should avoid using it.

Pregnant and breastfeeding women should avoid using astragalus supplements, as there is not enough evidence to support its safety.

Anyone with autoimmune diseases, or those taking immunosuppressant medications, should also avoid astragalus supplements. Individuals with lupus, multiple sclerosis, rheumatoid arthritis, and other autoimmune diseases should speak with their doctor before considering these supplements.

Lastly, individuals with diabetes should consult a medical professional before taking astragalus root.

How Do I Pick a Good Astragalus Product?

There are many different options when it comes to choosing an effective astragalus supplement. We’ve helped narrow it down for you by selecting the best astragalus supplements on the market in this guide.

When making your selection, you should take into account several factors. First and foremost, buying from a reputable company is very important. You want to ensure that you’re getting a quality product, and the easiest way to do that is to buy from a quality company.

You should also consider the specific type of astragalus used, the dosage amount, and the cost per serving. You don’t necessarily want the cheapest option, but you’ll want to find a product that offers good value at a fair price.
