What is a common characteristic of astragalus?

Astragalus is widely recognized for its supportive role in immune function and respiratory health. This adaptability can be attributed to its active compounds, such as polysaccharides and flavonoids, which are known to bolster the immune system by enhancing the activity of immune cells and improving the body’s resistance to pathogens. Additionally, astragalus has traditionally been used in herbal medicine to help protect against respiratory illnesses and difficulties, promoting overall lung health.

The other choices do not reflect the well-established benefits of astragalus. For instance, decreasing oxygen levels in the blood is contrary to the herb’s reputation for supporting respiratory health. High caffeine content is not associated with astragalus; in fact, it is naturally caffeine-free, making it unsuitable for those looking to avoid stimulants. Lastly, while skin elasticity is a significant concern in holistic health, astragalus does not specifically enhance it, unlike other herbs or nutrients that are known for supporting skin health directly. Thus, the statement regarding its support of immune function and respiratory health accurately encompasses the well-documented benefits of astragalus.
