s we head into the holidays, a gift that many of us wish for is a strong immune system to protect us not only from serious illness, but also from wintry coughs and sniffles. Robust immunity rests on three pillars, research shows: getting at least seven hours of sleep a night to allow immune functions to reboot; daily exercise to stimulate the production of white blood cells that fight off harmful bacteria and viruses; and plant-based foods to supply the antioxidants and phytochemicals needed to reduce inflammation and keep cells humming happily. In addition, we can enhance immunity by adding specific adaptogens and mushroom powders into our daily routine. These study-proven substances perform specific functions in the immune system that boost our resistance to illness. As powders, they can be easily added into drinks or foods, and they can also be taken as tinctures or pills.
Modulating Immunity with Adaptogens Used for millennia in China and India, adaptogens are plants that keep the body in balance by helping it adapt to stress. They 14

interact with the hypothalamic-pituitary-adrenal axis, a complex system of glands, hormones and receptors that helps manage homeostasis, stress responses and energy metabolism. “Adaptogens are a great way to boost immunity, especially if you are constantly sick and run down due to feeling stressed,” says Heather Hanks, a Plymouth, Michigan, nutritionist with USA Rx. Adaptogens typically take two or three weeks to become effective; follow package directions for proper dosage. Astragalus (Astragalus membranaceus), an herb called locoweed in the U.S., boosts immune function by increasing natural killer cell activity and enhancing the function of macrophages, the “immune sentinels” that reside in tissues. A recent review suggests that long-term use of astragalus might help prevent colds, and taking it for up to six weeks may relieve seasonal allergy symptoms such as runny nose, itching and sneezing. It has also been shown to improve recovery after illness, disease or prolonged stress and to help post-chemotherapy patients regain health.
