IMMUNE SYSTEM

The first line of defense against disease-causing microorganisms is the skin and mucosal barriers. Behind this is a complex defensive system. Collectively these parts are known as the immune system. 

The immune system neutralizes or destroys microorganisms and the toxins created by them wherever they attack the body via the extensive lymphatic system (comprised of the spleen, thymus gland, tonsils, bone marrow, and other organs and tissues). 

The network of lymph vessels (capillaries and lymphatics) drains the clear body fluid known as lymph from the tissues into the bloodstream. Special white blood cells that originate in bone marrow, known as lymphocytes, along with antibodies (proteins that neutralize foreign objects), are primarily responsible for carrying out the work of the immune system. The first line of immune defense is called the mucosal barrier. 

Mucous membranes are an integral part of the immune system. They form a protective barrier between the interior of the body and the outside environment. The mucosal barrier is permeable and allows nutrients into the body while protecting it from infectious agents, allergens, and other harmful substances.

If testing reveals that mucosal immunity is impaired, therapies should be initiated to rebuild it. In addition to evaluating mucosal immunity, it is relevant to assess cell-mediated immunity and humoral immunity. Cell-mediated immunity works by the activation of specialized cells called macrophages and natural killer cells, which destroy intracellular pathogens (disease-causing microorganisms). 

Humoral immunity is the aspect of immunity that involves antibodies. Knowing the status of these immune components provides a comprehensive understanding of one’s ability to fight infectious agents, defend against toxic exposures such as chemicals and heavy metals, and kill aberrant cancer cells. 

dōTERRA On Guard, a proprietary essential oil blend, provides a natural and effective alternative for immune support when used internally.

 dōTERRA On Guard protects against environmental and seasonal threats with essential oils known for their positive effects on the immune system when ingested.

 dōTERRA On Guard can be taken internally on a daily basis to maintain healthy immune function. It can also be used on surfaces throughout the home as a non-toxic cleaner. When diffused, dōTERRA On Guard helps purify the air, and can be very energizing and uplifting.
