Astragalus: A Great Adaptogen Herb

Posted by


Latin Name: Astragalus, Astragalus propinquus, Astragalus membranaceus

Common name(s): Milk Vetch, Astragalus, Huang Qi

Family: Fabaceae

Botany: Astragalus membranaceus is a perennial, native to Northern and Eastern China, as well as Mongolia and Korea.

Habitat: Astragalus does well in deep, sandy, well drained, and somewhat alkaline soils, but is fairly adaptable to other conditions.

History/Folklore: Astragalus has been a staple of Traditional Chinese Medicine (TCM) practice for thousands of years. As an adaptogen, it’s been used either alone or in formulas as a general Qi (or life force energy) tonic, promoting overall health and wellbeing. Astragalus membranaceus was introduced to the United States in 1925 through the USDA’s Plant introduction Office.

Parts used: root

Constituents: Polysaccharides (astragalosides I-IV and trigonosides I-III), isoflavonoids, saponins, triterpenoids

Energetics: Warming

Actions: Antioxidant, antimicrobial, anti-inflammatory, adaptogen, anti-tumor, cardiotonic, diuretic

Medicinal use: Astragalus has the general effect of increasing the body’s resistance to disease. In terms of how it works, herbalist Christopher Hobbs offers the following: “Astragalus increases the 'bone marrow reserve', enabling the body to produce more immune effector cells {such as t-cells}, aiding the immune system in its fight against pathogens.” In addition to its adaptogen qualities, Astragalus has been used to treat or as an adjunct therapy for a variety of conditions, including anemia, heart disease, hayfever, fatigue and lack of appetite during chemotherapy, and kidney disease. It also has strong anti-diabetes properties, lowering blood sugar levels. It may also have anti-tumor effects, specifically against melanoma and leukemia.

Common preparation: tincture, tea, capsules, and tablets

Contraindications: May interfere with drugs that suppress the immune system.

California Poppy

Early this spring, I began seeing them everywhere. These bright, beautiful orange flowers that lighten up even the darkest of days. I knew they were the state flower of California, but somehow, I had believed they were less common. Like the Lady Slipper, the state flower of Minnesota, my birthplace and home until last year. In reality, California Poppies [...]

Can Herbal Medicine Heal the World?

Herbalism has made a resurgence in North America over the past three decades or so. However, it has done so in a way that has stripped away much of the power, beauty, and wisdom. Plugging directly into the Western biomedical model’s view of health and disease, what constitutes herbal medicine these days tends to be primarily or solely focused [...]

Becoming Companions to the Plants

I am coming to believe that we have reached the limits of the analytical, logical approach to understanding. More precisely, the limits of relying on it as the sole or even dominant approach.Some questions that keep arising for me. "Where is the wildness here? Where are the weeds? The trickster animals?" Herbalism isn't ultimately about finding [...]

Zen Herbalism

We are being soaked right now with early spring rains here in Minnesota. Already, the nettle patch in my garden is bursting forth, bigger than ever. Soon, the dandelions will come, and then the clovers, plantains, and thistles. I'm anxious to get cracking on bottling more medicine. Even though it's cold outside, visions of green [...]
