THE GREAT PROTECTOR
Astragalus contains numerous different kinds of polysaccharides that have attracted a great deal of attention for their immunomodulatory action. It is traditionally known to strengthen what is known in China as wei qi, which is essentially surface level defenses.
A 7-day double-blind study showed that 1.23 grams of astragalus delivered twice per day activated the natural defenses more effectively than echinacea.
It has also been well-researched for its cardioprotective, anti-inflammatory, and longevity-enhancing properties.
