What is Astragalus?

Astragalus is a perennial herb. It belongs to the legume family and originally comes from Asia, where it grows in places like inner Mongolia and Tibet.

This plant has a scientific name, Astragalus membranaceus, but most people just call it astragalus. In China, it’s also known as Huang qi, and in other places, it might be called astragali radix or Mongolian milkvetch.

There are many different kinds of astragalus, around 2,000 types in total. Inside this plant, there’s a special group of natural compounds called astragalosides, and these are thought to be the reason why astragalus is good for your health.

Some people say that astragalus is an adaptogenic plant. In the past, it was used in Asia to help with lots of problems like feeling weak, having wounds, being anemic, having a fever, or dealing with allergies. It was even used for things like tiredness, not wanting to eat, and certain issues related to women’s health.

Doctors also use astragalus for problems with mucus and digestion. It can help with stomach problems like ulcers and diarrhea.

Research indicates that astragalus contains beneficial phytochemicals, including:

  • Flavonoids
  • Saponins
  • Polysaccharides

Overall, this is a unique herb hat holds both cultural and practical significance.

Potential Health Benefits of Astragalus:

Below are the top researched-backed health benefits of astragalus

astragalus and its benefits

1. Immune Health

Astragalus has potential benefits for the immune system. It can boost the activity of immune cells called macrophages, which are like the body’s quick-response team against harmful invaders.

A study from the 1970s showed that high doses of astragalus increased immune markers. When combined with vaccines, it also showed immunological effects.

In animal and lab studies, astragalus was effective against avian influenza and the Epstein-Barr virus, displaying antiviral properties.

2. Heart Health

Astragalus has been extensively studied for its potential in aiding viral myocarditis, an inflammatory heart disease.

Research suggests its antiviral, anti-inflammatory, and antioxidant properties could assist those with this condition. Clinical research, mostly in China, utilizes a patented astragalus form administered via an IV drip.

A meta-analysis involving 2,522 participants across 28 trials found that astragalus significantly lowered heart enzyme levels, improved treatment efficacy, and showed no major adverse reactions. However, the researcher highlighted some poorly executed trials and called for more robust studies to solidify astragalus’s efficacy for myocarditis.

3. Anti-Aging Benefits

Astragalus’s antioxidants may aid healthy aging. Free radicals harm cells, but astragalus helps to stabilize cells and protect them.

Lab studies show it resists oxidation, reduces oxidative stress, and boosts defenses. Astragalus has also been found to improve antioxidant levels in animals, promoting healthy aging.

4. Respiratory Support

Astragalus may help to ease asthma symptoms.

In a study with kids that had asthma, this herb was shown to improve forced expiratory results due to anti-inflammatory properties.

Another study found that blend of Dangshen and Chinese licorice enhanced lung function in adult asthmatics.

In one final study involving allergy-induced asthma mice, astragalus was found to help lower inflammation and lung mucus. This positions astragalus as a promising remedy for asthma symptoms and respiratory health.

It is important to note that additional human clinical research is needed to fully understand the potential health benefits of astragalus and to determine appropriate doses and usage.

Side Effects of Astragalus:

Astragalus is generally safe to consume for most people. However, there are a few potential side effects of astragalus to be aware of.

Safety studies show that possible astragalus side effects can include rash, itching, nasal symptoms, or stomach discomfort, but these are uncommon. Astragalus may also interact with medications that suppress the immune system.

Before using any supplements containing astragalus, it is crucial to seek advice from a healthcare professional, especially if you have pre-existing medical conditions, are taking medications, or are pregnant or breastfeeding.
