Astragalus tea, derived from the root of the astragalus plant (Astragalus membranaceus), has a long history in traditional Chinese medicine (TCM). Often called Huang Qi, or “yellow leader,” this herb has been used for over 2,000 years and is recognized as one of the 50 foundational herbs in TCM. Native to northern and eastern China, Mongolia, and Korea, the plant’s thick, fibrous root is primarily used.
Key Health Benefits of Astragalus Tea
Astragalus tea is associated with several potential health benefits, largely due to its active plant compounds like polysaccharides, saponins, and flavonoids. These compounds contribute to its adaptogenic properties, helping the body manage various types of stress. The herb has been traditionally used to enhance overall vitality and support the body’s natural defenses.
Astragalus is recognized for its immune system support, potentially enhancing the body’s resistance to illnesses by stimulating immune function. Some evidence suggests it can increase the production of white blood cells, which help prevent illness. It may also help fight viral infections, including the common cold.
The tea also possesses anti-inflammatory properties, potentially helping to reduce inflammation throughout the body. Its antioxidant content, including flavonoids and saponins, helps protect cells from damage caused by free radicals. This action can contribute to overall cellular health and may offer relief in conditions linked to chronic inflammation.
Astragalus tea may offer cardiovascular benefits by supporting heart function and contributing to healthy blood pressure regulation. Research suggests it can help improve heart function, particularly for individuals with conditions like heart failure, and may support blood vessel health. It is thought to widen blood vessels and increase the amount of blood pumped from the heart.
Making and Enjoying Astragalus Tea
Preparing astragalus tea at home is a straightforward process, whether using dried root slices or pre-packaged tea bags. For dried root, a common method involves simmering 1 tablespoon of shredded astragalus root with 2 cups of water, covered, for about 10 minutes. Alternatively, a decoction can be made by boiling 8-15 grams of dried root in 350-400 mL of water for 20-30 minutes, allowing the active compounds to extract.
After simmering or steeping, the tea should be strained before serving. Astragalus tea has a mild flavor, with slightly sweet and earthy undertones. It can be enjoyed hot or iced and may be blended with other herbs like ginger, orange peel, or licorice root for varied flavors and additional benefits.
Important Safety Considerations
While astragalus is generally well-tolerated, certain individuals should exercise caution or avoid its use. People with autoimmune diseases, such as lupus, rheumatoid arthritis, or multiple sclerosis, should avoid astragalus as it may stimulate the immune system and potentially worsen symptoms. There is not enough reliable information to confirm its safety during pregnancy or breastfeeding, and some animal research suggests it could be toxic to the fetus.
Astragalus may interact with certain medications. It might decrease the effectiveness of immunosuppressant drugs, such as those used after organ transplants or for treating cancer, due to its immune-activating properties. It could also interact with blood pressure medications, potentially causing blood pressure to drop too low, and may affect how the body processes lithium, leading to increased levels of the drug. Consulting a healthcare professional before using astragalus tea is recommended, especially if you have existing health conditions or are taking other medications.
