Q: Dear Dr. Mao,
My grandmother is getting older and I am worried that getting colds at her age will be more dangerous. Is there something she can take to improve immunity?
A: A famous natural treatment for colds is the use of zinc lozenges. In cases of zinc deficiency, the immune system does not function properly. Because zinc is commonly deficient in the diet, especially among senior citizens, nutritional zinc supplementation may certainly be useful for those who get sick easily. A recent study suggests that zinc and selenium taken together in nutritional doses can reduce the number of infections in nursing home residents. Ten other studies performed in third world countries have found that zinc supplements at nutritional doses can increase resistance to infection.
She might also try the “Perpetual Shield” and “Enduring Youth” herbal formulas by Traditions of Tao to boost her immune system and help combat the effects of aging. Of course, discuss with your physician before beginning any new health regime.
