Our immune system is comprised of many biological structures, and is quite a wondrous thing. Give it the tools it needs, and it detects and protects us from potentially fatal invaders including bacteria, parasites, and viruses. As with anything else if you don’t put the right fuel in it’s not going to be able to perform at its best, so here I’ll discuss how to do that in a way that isn’t counterproductive.
With flu season upon us, “immune boosters” are all the buzz. No one wants to get sick! Nature provides medicine for every ailment – if you have even a bit of influence over whether you get sick or not or how quickly you recover from illness, why wouldn’t you want to take advantage?
However, there is such a thing as doing it wrong.
Let’s look at it as three different categories- immune stimulators, immune modulators, and immune essentials.
Many people refer to these as “immune boosters,” but I much prefer to use the term “stimulators.” These are the warriors you keep in your medicine cabinet to launch an attack when you get an invader. They rev up your immune system for war- they can be used prophylactically after exposure, used to kick out a pathogen at the first sign of illness, or used to reduce the duration of an illness. They are not required for immune function, but they can be extremely effective at helping and most have the research to back that. (See a sampling of available studies below- 111 of them!)
However, you don’t always want to stimulate, or “boost” your immune system! These should only be taken on an as-needed basis, not daily. Think of it as sending soldiers out to war- fighting off the enemy is a really tough job. Imagine if you were to send those soldiers off every day to fight, whether they were needed or not. They’d get tired and burnt out after awhile, wouldn’t they? Generally immune stimulators want to be used for 3-4 days, or as directed for your particular ailment by your naturopathic practitioner or herbalist. Immune stimulators are not ideal for those with autoimmune disease or those on immune – suppressing drugs. The following are some of my favorite immune stimulators. But bonus- a few of these do TWO jobs- immune stimulating and immune modulating. Keep reading to learn what that’s all about!
Examples of immune stimulators:
Wild echinacea purpurea near my house
These are the immune regulators; it is their job to keep the immune system at a healthy baseline. Modulation means being strong enough for pathogens and foreign cells to be destroyed, but also not hyper-reacting to common foods, allergens, environmental organisms, or your own body cells. Take these daily as gentle therapeutics, use prophylactically after exposure, or to support your system in fighting off pathogens at the first sign of illness. Some modulators can also help to stimulate, but due to their regulating activities they are safe for autoimmune disorders.
Examples of immune modulators:
Dried chaga chunks are used to make a delicious tea. Order my wild Wisconsin harvested chaga here and learn more about chaga at Eden Wild Food
Immune essentials are crucial nutrients that are required for functioning of the immune system. They are not optional. A balanced diet should provide most of what we need, however many times a supplement is helpful for filling nutritional gaps, especially if your diet is not ideal. In the presence of illness or as a prophylactic help, higher doses than the minimal amount to prevent deficiency can be helpful. For example, I like to take a gram of vitamin C every couple hours when I’m feeling under the weather. However, more is not always better for many vitamins and minerals- you want daily levels that allow the body and immune system to function at optimum levels, without overdosing. For example, overdosing on the vitamin D via supplementation can cause health issues such as a decrease in bone mass. Too much zinc (over 100 mg/day) can actually suppress your immune system. Consult your health practitioner for doses that are right for your body.
Examples of immune essentials:
- Vitamin C
- Vitamin A
- Vitamin D
Rose hips have 946% more vitamin C than oranges! Read more here.
So to sum up, these natural medicines can be a wonderful, effective way to stay healthy, but be sure to choose the methods that are right for you- rev up and/or regulate your immune system, and of course supply the vitamins and minerals that are the basic foundation of our bodily functions.
