4. Astragalus

This herb isn’t well known in the U.S., but it should be. There are studies showing that astragalus assists the immune system by stimulating the production of immune cells in the bone marrow and lymph glands. This herb has also been discovered in studies to increase the number and stimulate the activity of killer cells in the body that target cancer cells. Astragalus also produces immune compounds such as immunoglobulin. One study conducted in China in 1997 found that when they gave astragalus to elderly mice, it restored their immune systems to resemble the ones found in mice that were only 10 weeks old!


5. Cloves

These tiny flower buds not only smell great and have analgesic compounds, but they are also full of important nutrients such as fiber, calcium manganese, magnesium, and omega-3 fatty acids!

Chew cloves whole, add them to your foods, or consume clove oil supplements as directed.
