Latin Name: Astragalus membranaceus
Herb Class/Action: Astragalus is classified as an adaptogen, immunomodulator, and tonic herb.
Parts of Plant Used: The root of the astragalus plant is primarily used for medicinal purposes.
Flavors: Astragalus root has a sweet, slightly earthy taste.
Energetics: Astragalus is energetically warming and tonifying.
Medicinal Properties:
- Immune Support: Astragalus is revered for its immunomodulating properties, which enhance the function of the immune system and increase resistance to infections and diseases. It contains polysaccharides, flavonoids, and saponins that stimulate the production of white blood cells, enhance phagocytosis, and improve immune surveillance. Astragalus is used preventatively to strengthen immune defenses and shorten the duration and severity of colds, flu, and respiratory infections.
- Adaptogenic Effects: Astragalus acts as an adaptogen, helping the body adapt to stress and maintain homeostasis. It regulates the hypothalamic-pituitary-adrenal (HPA) axis, reducing the production of stress hormones such as cortisol and adrenaline. Astragalus enhances resilience to physical, mental, and emotional stressors, improving energy levels, stamina, and overall well-being.
- Tonic Properties: Astragalus is considered a vitalizing tonic in traditional Chinese medicine (TCM), promoting longevity, vitality, and endurance. It strengthens the spleen and lungs, tonifies Qi (vital energy), and nourishes the blood and fluids. Astragalus is used to boost energy levels, improve digestion and metabolism, and support cardiovascular health.
In the Garden: Astragalus is a perennial herbaceous plant native to China and Mongolia but cultivated in many parts of the world for its medicinal properties. It prefers well-drained soil and full sun to partial shade. Astragalus has erect stems with pinnate leaves and clusters of small, yellow or purple flowers that bloom in the summer. It is often grown in herb gardens, wildflower meadows, and naturalized areas or used as a nitrogen-fixing cover crop in sustainable agriculture.
Culinary Uses: Astragalus is not commonly used for culinary purposes due to its fibrous and woody texture. However, it may be simmered in soups, stews, or broths to extract its nutritive and medicinal components. Astragalus root slices or powder can be added to herbal decoctions or teas to enhance immune support and overall vitality.
Precautions: Astragalus is generally safe for most individuals when used as directed. However, individuals with autoimmune diseases, organ transplants, or immune system disorders should consult a healthcare professional before using astragalus, as it may stimulate immune function and exacerbate autoimmune reactions. Pregnant or breastfeeding women and individuals taking immunosuppressant medications should also exercise caution when using astragalus.
