This is the time of year when we are especially concerned with our immune system. Colds, flu, coughs–we want to prevent these conditions and, if we do succumb, we want to shorten their duration and severity.
There are many things we can do. We can try to avoid exposure to pathogens. We can eat healthy, avoid temperature extremes and too much stress. But these measures, and others, often fall short. Some of us get colds and/or the flu every season, sometimes more than once, while other’s seem to have an inherent resistance.
We all have some degree of inherent resistance. Our immune system is designed to protect us from these infections when working properly. Repeated, or chronic infections, including mild cases of colds and flu, can be signs of a weakened or compromised immune system.
In this short article, I am going to list some of my favorite “herbal remedies” for enhancing immune function. Choosing herbal supplements, when so many choices are available, can be daunting. I will break them down into categories, such as “prevention,” “treatment,” and specific health conditions. (Please note that my use of the terms “prevention” and “treatment” are not intended to imply medical actions. Only drugs, as per the FDA regulations, can be said to cure, treat, prevent or otherwise mitigate disease. I am using the terms only to clarify the nature of their effect on the immune system).
I will provide several choices, when appropriate, and you choose the supplements that seem best for you. In general, I will list combination products first, and then single herbs afterwards. For more information on each supplement, please refer to the more detailed information provided in the Phyto-Tech™ Product Reference Guide. Indexes located on pages 5 and 110.
