Top 10 Ways to Use On Guard Essential Oil
DIY Cleaning Spray
On Guard is a must-have, therapeutic-grade essential oil blend that every home should have on hand.
Made with sweet orange, rosemary, clove, cinnamon, and eucalyptus essential oils, this powerhouse blend offers a natural way to support the immune system and fight off germs.
Each ingredient brings its own antibacterial and immune-boosting benefits — and when combined, they create a potent, versatile formula.
On Guard doesn’t just support wellness — it also doubles as a natural disinfectant for your home. From cleaning surfaces to purifying the air, it’s one of the most multi-purpose blends I own. Best of all? It’s pure, effective, and smells amazing.
No wonder I use it for everything!
This list was hard to narrow down — On Guard is one of the most powerful tools I use to keep my family healthy year-round. These 10 ideas are simple to do and backed by research connecting immune function, oral health, and even brain health.
Mix with a tbsp of water, gargle for 1 minute then swallow at the on-set of a sore throat.
This helps kill bacteria in the mouth and throat, which can reduce inflammation and viral load early.
Put 5 drops Oregano and 5 drops OnGuard in a capsule and take 3 times daily at the on set of cold or flu symptoms.
These oils contain powerful compounds like carvacrol and eugenol that support the immune system and fight pathogens.
Put on the soles of kids feet in the morning and at night (diluted with fractionated coconut oil in a roller bottle) during cold & flu season (start in September) to support immune system.
The feet absorb oils quickly and stimulate reflex points connected to the immune system.
Put several drops in a bowl of very hot water and breathe in the vapors as the oil begins to volatilize when you have lung congestion. (or put in diffuser and inhale during the night)
Helps open airways and reduce respiratory inflammation thanks to eucalyptus and rosemary oils.
Put 20 drops in a spray bottle of water and vinegar. Shake and then use to clean and sanitize kitchen counters, sinks, floors, door knobs, and bathroom surfaces.
Natural antibacterial and antifungal properties make it a non-toxic way to sanitize your home.
Add to your dishwasher or laundry for micro clean dishes and clothes.
Reduces bacteria and odors while avoiding synthetic fragrances and chemicals.
Apply to bee and insect stings to neutralize the toxin and relieve the pain.
Clove and cinnamon oils have analgesic and anti-inflammatory effects.
Gargle and brush daily for healthy teeth and gums and to prevent and treat gum disease.
Reducing gum disease-causing bacteria may also protect your brain — oral health is linked to dementia risk.
Diffuse in your home, school, daycare or business to kill air borne pathogens, inhibit mold and build immune systems.
The antimicrobial blend supports air quality and the warm scent reduces stress and supports immunity.
Mix 2-3 drops of OnGuard and 2 drops of lemon EO with 1 tsp of raw honey (Manuka if you have it) for a cold or cough or sore throat relief for kids and adults.
Soothes irritation, reduces microbial load, and provides a natural immune boost for kids and adults.
