Astragalus: Ancient Remedy for Modern Health Issues

What is Astragalus?

Astragalus is an adaptogenic plant that belongs to the legume family, also known as “milkvetch” or “huang qi” in traditional Chinese medicine. It has been used for centuries in China to strengthen the body's immune system and promote healing. [1]

The Astragalus root is the most commonly used part of the plant. They usually turn it into tea, capsules, or extracts for medicinal purposes.

Astragalus has several health benefits, such as boosting the immune system, reducing inflammation, and improving the health of the heart and the brain.

As an adaptogen, it helps the body cope with stress and alleviates its adverse effects.

Astragalus Benefits

1. Boosts The Immune System

Several studies have found that astragalus can increase the production of white blood cells, which play a crucial role in the body's immune response. These white blood cells, including T-cells and natural killer cells, help to identify and destroy foreign invaders such as bacteria, and viruses. [2] [3]

Astragalus also contains compounds called polysaccharides, which have immune-modulating effects. These polysaccharides may help to regulate the immune system and enhance its ability to defend against pathogens like liver infections. [4] [5]

Some research has also suggested that astragalus may be helpful in the prevention and treatment of respiratory infections, including the common cold and flu.

2. Regulates Blood Sugar Levels

Astragalus increases insulin sensitivity in people with diabetes 2, improving glucose uptake by cells and controlling blood sugar levels. [6]

Also, Astragalus contains compounds called saponins, which inhibit the absorption of carbohydrates in the digestive tract. This process slows glucose absorption into the bloodstream and prevents blood sugar spikes.

Finally, inflammation is a critical factor in type 2 diabetes development. Astragalus contains anti-inflammatory compounds such as polysaccharides, which can reduce inflammation in the body and improve glucose control. [7]

3. Protects The Heart

Astragalus improves heart function by increasing heart contractility and reducing oxidative damage to the heart. The flavonoids present in astragalus are antioxidants that help prevent plaque buildup in arteries and the narrowing of vessel walls by protecting the inner wall of the vessel.

A 2014 study suggests that astragalus injections in combination with conventional therapies may improve outcomes for patients with viral myocarditis (inflammation of the heart wall). [8]

Studies have also shown Astragalus to reduce cardiac fibrosis, improve blood circulation, and reduce levels of LDL (bad) cholesterol.

4. Enhances Brain Function

Astragalus improves brain function by increasing oxygen flow to the brain, improving blood circulation, boosting energy and alertness, and increasing levels of antioxidants.

It may also help to protect against age-related cognitive decline and reduce stress and anxiety. [1]

Thanks to its neuroprotective effects, Astragalus improves memory and concentration and enhances mood by increasing dopamine and serotonin levels. [9]

Safety And Side Effects

Astragalus is safe when taken in recommended doses.

Side effects may include nausea, diarrhea, and allergic reactions. [10]

Long-term use of astragalus may cause an imbalance of electrolytes or interfere with medications. It is important to discuss your usage plan with a healthcare provider.

People with autoimmune diseases, bleeding disorders, or those taking immunosuppressants should not use astragalus. This also applies to Pregnant and breastfeeding women.
