Astragalus: It Stops Aging, Cancer, And More!

Astragalus is a potent medicinal herb

Astragalus is a class of herbs found in northern Asia that’s been used to treat fatigue and sickness for thousands of years.

Some of the plant constituents have shown to be so potent that they’re now being used as the basis for different drugs to treat cancer, fatigue, and subdue ulcers, among other things.

The Health Benefits of Astragalus

Astragalus seems to work its magic through the following mechanisms:

  • It causes your body to produce more telomeres, a part of your DNA that protects chromosomes from degradation
  • It contains a unique class of polysaccharides which are very biologically active
  • It improves the rate of replication of immune cells called macrophages

These three properties are very unique to astragalus, and are one of the reasons its such a wonderful medicinal herb.

It’s health properties are so unique that isolated compounds from its polysaccharides are being used as the basis for billion dollar pharmaceutical drugs being used to treat some of mankind’s most daunting health problems.

It’s also one of the reasons holistic wellness should precede medicine.

How Astragalus Stops Aging

Astragalus is uniquely healthy for your cellular health because of its ability to protect your body’s telomeres from degradation.

Telomeres are small pieces of DNA located at the edge of your chromosomes.  When your cells replicate telomeres help prevent your DNA from unraveling and keep it locked into place. They serve a similar function as the plastic caps on the edges of your shoelace.

Whenever your cells replicate telomeres shorten a wee bit.  After so many replications the stubby telomeres reach a critical point where they’re no longer usable and cells begin their programmed death, a process called “apoptosis.”

The gradual shortening of telomeres is an important component of ageing and different types of cancer.

Astragalus causes your body to increase its production of a substance called “telomerase”, which is an enzyme that enables the production of more telomeres. In clinical studies mice treated with extracts of astragalus root had telomeres that were longer and degraded more slowly than a control group.

What’s more impressive is that despite these remarkable effects on cellular health there’s apparently no toxicity from astragalus if taken at reasonable dosages.

Astragalus Helps Improve Sickness and Heal Wounds

As stated before, astragalus contains some polysaccharides which are just darn unique.

The most notable compounds are called formononetin, calycosin and astragaloside IV, and seem to do the following things in your body:

  • Reduces the amount of nitric oxide released from cells, which reduces inflammation
  • Causes certain genes and metabolic pathways to be shutdown which would otherwise cause blood and chemicals to flow to wounds
  • Activates other genes and pathways which activates different immune cells

Because of this astragalus is fairly robust at healing sickness.  It’s been used to treat ulcers, swollen wounds, reduce hemorrhaging, and serve as a complimentary input to cancer treatments.

One of my favorite studies on astragalus was published recently in the journal Clinical Investigative Medicine, and it studied the ability of astragalus to reduce fatigue in cancer patients with very developed cases.

The patients were treated with a purified extract of Astragalus membranaceous in two 1 month cycles. After the first month 82% of patients reported feeling better and more energetic, and the following month 71% of the remaining group reported better feelings of energy, vitality, and youth.

The study was a double-blind placebo controlled study and fairly high quality.

Astragalus is Good For Diabetics

Astragalus seems to be a decent food for diabetics. For a reson that’s not entirely clear patients who take astragalus exhibit better blood sugar control.

The different polysaccharides protect against radical scavengers, and the benefits astragalus provides to cellular health seem to carry over in its ability to metabolize different nutrients.

Astragalus Supplements, Dosages, and Side Effects

One of the benefits of astragalus is that despite its potent behavior within the body it seems to be benign at almost all doses. As far as I know there are no cases where astragalus caused harmful side effects in patients.

When you buy astragalus at the store you’ll want to buy Astragalus Membranaceous , as it’s the form most studied and easily consumed by humans.

You can either buy astragalus membranaceous in its root form or as an extract.  Astragalus supplements typically come in powdered form, but it’s also  available in capsules.

With most supplements the amount of astragalus contained will be between 250-1000mg, and as far as I know this is fine.  Only if you’re taking significantly more than this or taking several doses a day should you exercise caution.

It’s also possible that at very high dosages astragalus might suppress your immune system, and taking it with immune-stimulating drugs might cause side effects.

Talk to your doctor if you have any questions about this.

Who Should Take An Astragalus Supplement?

Because of its widespread health benefits and benign nature, most people would benefit from having some astragalus in their diet.

However, due to its unique properties astragalus probably provides the most help to the following people:

  • elderly people looking for a non-invasive way to fight the vagaries of old age
  • people looking to reduce fatigue or reduce the collateral damage from severe chemotherapy or drug treatments
  • anyone with a brittle immune system that’s sensitive to over the counter medication
  • people looking for a natural/homeopathic way to help control blood sugar

Of course, if you have specific questions about a condition you should consult your doctor or licensed medical professional. This is not specific medical advice.


Astragalus is a pretty bodaceous herb. There are a large amount of studies that verify its health benefits, and the fact that it’s the subject of mimicry in pharmaceuticals alludes to its medicinal potency.

  1. I started taking astragalus extract 3 months ago. It cleared up my irregular heartbeat. I had a heart scan a couple of yrs. ago and my heart sounded like a gumball machine. Last month I had another heart scan and I asked the technician If there is any irregular heart beat. He said, “just slightly but not enough that I should have to worry to So there is proof that it does improve the function of the heart.


  2. The above picture of two fan shaped leaves is not astragalus leaves and the powder looks a little too green to be astragalus. The two leaves are from a ginkgo biloba tree.


    1. Thank you! That lame slip up should make every reader question the whole article. That’s just ridiculous – get it together. Perfect example of how you should do your own research and ever believe everything you see on the internet because any yahoo can throw their bs out there. Gah.


  3. If I get a virus it take exactly 5 hours for me to feel better with astragalus. On the down side I began taking it regularly and in six months I had aches in my hips when I stopped taking it, the aches stopped.


    1. Susan,

      Thanks for this. Most people who take astragalus use it for its benefits to the immune system, and you might not realize it but testimonials like yours do a lot to “sway” people into deciding to try it.


      1. If you take astragalus capsules as I do, do not take any blood thinners with it because it already works like a blood thinner. See and scroll down to the bottom of the page.


  4. What is the difference between Astragalus root and standardized Astragalus. I know that the standardized is much more expensive. So what’s the difference?


    1. Sally,

      Astragalus root is just the root itself with no additional processing, except for being powdered. It’s the whole plant. Standardized astragalus is processed to contain a certain amount of the active ingredient. In theory these should be more potent, but you also have more processing so more care is necessary to make sure it gets done right. You have an increased risk of solvents and contamination with standardized products.


  5. On another site the Chinese claimed that astragalus improves the heart rythem. I take 2 to 3 caps a day and it improves my heart beat and rate by 90%.


  6. So happy to read all this information. I am always so scare to take herbs .thank you again l be taking my Astragalus without fear.


  7. I have fibromyalgia :pain all over my body from head to toe, chronic pain, I wear a pain patch 24 hours a day 7 days a week.
    Has anyone had any pain relief while taking Astragalus in any form be it drinking as a tea or taken in a capsule


    1. I believe you are correct. I didn’t notice the error until I went back up the page to see. Ginkgo is another fabulous herb, btw. I take it everday along astragalus, jiaogulan, pterostilbene, ashwagandha, etc.
