Not certain where this originated, and have not tried this since we have not had colds, flu, or other contagious diseases for 40 years while enjoying the Creator's lifestye and eating plan. However, am told that as simple as it may be, this one works!
1 tsp. unheated honey
1/4 tsp. cinnamon
Mix and use in hot herbal tea, or eat slathered on an apple slice.
(Do not feed honey to infants under one year.)
