Unlocking the Immune-Boosting Power of Astragalus Membranaceus

Astragalus membranaceus is one of those medicinal plants that most naturopaths know, love and hold in high regard. The immune boosting powers of astragalus are well known, but have you considered what might affect quality (and therefore the results you’re likely to get from this ingredient)?

Astragalus has been used extensively in Western Herbal Medicine for centuries and over 2,000 years in Traditional Chinese Medicine (TCM).

In 2020 when interest and research into potent, effective herbal medicines blew up, as you expect, astragalus was high on the list of ingredients studied. We ourselves saw many new studies come out alongside recommendation from experts around the world on its therapeutic application and potential.

How astragalus supports immunity

With regards to supporting immunity, astragalus works through multiple pathways, but ultimately provides immunomodulation, helping the body maintain a state of homeostasis.

It does this through ‘enhancing the immune hormone index, promoting the proliferation of immune cells, stimulating the release of cytokines, and effecting the secretion of immunoglobulin and conduction of immune signals’.1

This is vitally important to both prevent immune infection as well as recover from attacks on the immune system.

More than 200 compounds from astragalus have been isolated and identified. Many of these having a positive impact on immune modulation, adaptogen activity, cardiovascular health, among other benefits.

Astragalus and sustainable sourcing

Like all medicinal plants that have an increased demand, we recommend that you may want to consider supply and sustainability issues. Inferior quality material inherently makes its way to the market and – without proper knowledge, screening and due diligence – ends up in the formulations that practitioners prescribe.

We’ve included astragalus in Give Back Health Clinic Collection RejuveGen.

The astragalus we’ve used in RejuveGen is derived from 100% water extract, which extracts out the key active constituents (e.g. polysaccharides) for maximum therapeutic effect.

Additionally, the material we use is organically grown and sustainably sourced.
