Habitat & Cultivation : Astragalus is indigenous to Mongolia, as well as northern and eastern China. The cultivation of Astragalus typically involves growing it from seed during the spring or autumn. This herb flourishes in sandy, well-drained soil and requires ample sunlight. The roots of Astragalus plants, typically harvested when the plants are four years old, are collected during the autumn season.
- Triterpene saponins (astragolosides)
- Isoflavonoids (formonentin)
- Immune stimulant
- Chinese investigations : Research in China suggests that astragalus possesses diuretic properties and may contribute to lowering blood pressure while enhancing endurance. A clinical trial conducted in 2012 revealed that a daily dosage of 5 grams of astragalus root helped stabilize kidney function in patients with chronic kidney disease, thereby delaying the necessity for dialysis. These findings underscore the potential health benefits of astragalus in the context of kidney function and overall cardiovascular well-being.
- Western research Recent : Research in the United States has emphasized the potential of astragalus in restoring normal immune function, particularly in cancer patients. Clinical evidence indicates that, similar to several other herbs, cancer patients undergoing chemotherapy or radiotherapy may experience faster recovery and longer survival when astragalus is administered concurrently. This highlights the promising role of astragalus in supporting immune function during cancer treatment.
Traditional & Current Uses
- Tonic & endurance remedy : Astragalus is regarded as a classic energy tonic, and some believe it may even be superior to ginseng, especially for young individuals. In Chinese traditional medicine, it is believed that astragalus has the ability to warm and tone the wei qi, a protective energy that circulates just beneath the skin. This is thought to aid the body in adapting to external influences, particularly cold conditions. Astragalus is known for boosting immune resistance and visibly enhancing physical endurance.
- Control of fluids : Despite being a vasodilator, encouraging blood flow to the surface, astragalus is employed for its effectiveness in addressing issues such as excessive sweating, including night sweats. Additionally, it is known for its ability to alleviate fluid retention and reduce feelings of thirstiness. Astragalus supports normal kidney function and is believed to have protective effects on the kidneys, potentially shielding them from damage.
- Immune stimulant : While not typically considered a herb for acute illnesses, astragalus proves to be a valuable medicinal option for addressing viral infections, such as the common cold. Its potential in supporting the immune system and mitigating the effects of viral infections makes it a useful herbal remedy, especially during times of increased susceptibility to such illnesses.
