How to Protect Your Immune System Naturally?
All you have to to to protect yourself naturally from picking up bugs is to practice a few simple ‘common sense’ measures.
The #1 MOST important and best way to protect your immune system’s health is to Promote a healthy microbiome.
Your first line of defense against any bugs is your gut. Natural health practiioners have known this for years, but science is finally catching up. Science has finally made the game changing discovery that up to 70% of your immune system is located in your gut.
This means your food can act as a medicine (or poison) depending upon your dietary choices. Do you eat to satisfy your needs for delicious foods that nourish your body and mind. Or, do eat purely for the entertainment value and experience of eating. Or, do you eat comfort foods that suppress uncomfortable emotions (as in emotional eating).
Simply choosing to eat whole foods (not processed) that are organically grown is fundamental to good health and supports a strong immune system. Essential oils, herbs and health supplements that support your individual needs can also play a vital role in protecting your immune system.
The VERY worst thing you can do to undermine your immune response is to eat sugar, or food that turns immediately into sugar, i.e. breads, pasta and other carbohydrate dense foods. Listen to your body and how it feels after consuming food for clues about what nourishes or possibly damages your gut.

Best Antimicrobial Oils by Chemistry - What the Research Shows
Alcohols (The Lovers)
Some of the most well-known and beloved oils in aromatherapy are in the alcohol chemical class. Alcohols are friendly oils that blend well with most other essential oils.
The monoterpene alcohols are found in a large number of essential oils. Terpenes give most essential oils antimicrobial effects.
Adding an additional oxidation pathway, such as with monoterpenols (a terpene alcohol), can lead to more synergistic effects.
Synergistic effects are observed when the combination of substances has a greater effect than the sum of its individual effects. The synergistic quality of alcohols is what makes them stand out and worthy of being considered for immune protection.
Essential oils containing terpene alcohols have the highest antibacterial action, after phenols and aldehydes.
Alcohols are generally nontoxic, non-irritating, nonallergenic and nonmutagenic (do not cause cell mutations or genetic alterations).
Phenols (The Warriors)
Notably phenols require careful handling due to their tendency to cause chemical burns. They have a viscous (thick, sticky) consistency. Their high viscosity makes them less volatile and subject to rapid evaporation. Phenol’s characteristic scent is intensely sweet.
Thymol, eugenol and carvacrol are characteristic components of this class of essential oils. Phenol containing oils have strongly antiseptic, anti-bacterial, disinfectant and stimulating properties.
Thymol - Results of a study on the chemical Thymol (a constituent of the essential oil Thymus vulgarius) suggest the potential role of thymol as a natural immuno-stimulatory drug which can be used in the treatment of various immunological disorders.
Eugenol - The influence of clove essential oil in antimicrobial activity was studied. The results of the study suggest that the characteristics of organic substances, i.e. eugenol, play an important role in destroying bacteria. Up to 89% of clove oil is eugenol.
Carvacrol - The biological effects of carvacrol was studied (oregano essential oil contains up to 80% carvacrol). It’s antimicrobial, antioxidant, antifungal, immunomodulatory, anticancer and anti-inflammatory properties were shown to prevent free radicals and hazardous compounds from interacting with cellular DNA.
Carvacrol has the ability to change the gut microflora, improving digestion and absorption of nutrients.
Aldehydes (The Cleaners)
Highly unstable, aldehydes easily oxidize and become rancid in the presence of heat, light and air.
Citral, neral, geranial and citronellas are characteristic components of aldehyde containing essential oils. Essential oils containing primarily aldehydes have the highest antibacterial activity, along with phenols.
Citral is an aroma compound used frequently in the perfume industry for its citrus effect. It’s also used as a food flavor and to fortify the effects of lemon oil.
Citral has strong antimicrobial qualities, Lemongrass oil contains 70–80 percent citral. Citral has been studied and shown to be effective for its bactericidal and fungicidal activity.
Neral, is classified as a monoterpene aldehyde. Its aroma is similar to lemons. Neral has been studied and shown effective as an antibacterial agent. One study showed the antimicrobial prosperities of Lemongrass (Cymbopogon citratus) to be effective against pathogenic bacteria.
Citronellal has a distinctive lemon scent. Research on its insect properties show its high effectiveness, especially against mosquitoes. Research has also demonstrated citronellal strong anti fungal properties.
Geranial has a light, sharp, fresh lemon scent. Studies conducted on the aldehydes geranial (alpha citral) and neral (beta citral) showed both to be effective as antibacterial agents.
Oxides (The Liberators)
The most common oxide in aromatherapy is 1,8-cineole. Also known as eucalyptol.
Oxide molecules are chemically very stable. Essential oils having a camphoraceous scent usually contain oxide formations, i.e. eucalyptus and rosemary cineole.
1,8-Cineole has been shown to have expectorant properties and to stimulate the respiratory and digestive systems.
Top 10 Essential Oils to Protect Your Immune System
Research shows these essential oils are effective as broad spectrum anti-microbial agents. You can use them to protect your immune system.
Oregano (Origanum vulgare) - Phenol
- Contains powerful anti-microbial properties
- Studies show oregano essential oil is a potent antiseptic, germ killer
- Promotes relief for a broad spectrum of infections
A 2014 study showed the antiviral efficacy and mechanisms of action of oregano essential oil were due to its primary component carvacrol.
Safety Cautions: Strong irritant to the skin and the mucous membranes. Maximum dermal use level is 1.1% dilution for safe skin application. Possible drug interactions, may inhibit blood clotting, possible embryo-toxicity. Avoid in pregnancy and breastfeeding and with children under two years of age. Avoid with hypersensitive, diseased or damaged skin.
