8 Germ Fighting Essential Oils – To Boost Immunity

Best Germ Fighting Essential Oils – Derived from Common Garden Herbs

If you want to fortify your body against viruses and bacteria that invade, attack, and cause a host of unpleasant and inconvenient symptoms, then you might consider essential oils as a way to boost your immunity this cold and flu season.

Remember that essential oils come from plants – often herbs, flowers, seeds, stems and bark. Some plants are better than others at warding off bacteria, viruses, fungi and other pathogens. Let’s use companion gardening to put this into perspective and fully understand it. 

Organic gardeners know that certain, strongly scented herbs and flowers actually repel bugs and disease. For example, planting basil next to your tomatoes may help strengthen the plants and ward off invaders. Other companion herbs that protect plants against diseases and pests include rosemary, sage, thyme, and oregano.

Sure, enough, many of the same plants that afford gardeners chemical-free protection of their growing vegetables also offer protection to humans by arming their immune systems against viruses and bacteria. Rosemary oil, thyme oil, and oregano oil are among the most powerful, illness-fighting, immune-boosting essential oils you can find. 

Because these essential oils are so strong, you will likely have to adjust the ratio if you are preparing EO blends using these powerful germ fighters and illness busters. It only takes a few drops of the strongest-smelling oils, which also happen to be the most potent and powerful, to elicit the desired effects.

Sage oil, while it is available for purchase, may be risky in personal applications as it is known to be toxic to the body. You can safely use Clary sage oil in your diffuser as well as massage it into the skin.

1) Rosemary Oil as an Immune Booster

Rosemary oil is analgesic, antibacterial, anticancer, anticatarrhal, antifungal, anti-inflammatory, antioxidant, and expectorant in nature.

In addition to fighting cold and flu viruses and bacterial, rosemary oil will reduce inflammation in the body. Chronic inflammation is the immune system over-reacting, which slowly wears down the body’s ability to fight infections such as cold and flu germs, when they become present. So if you reduce inflammation, you can help your body regain immune response and arm yourself against cold and flu.

An expectorant helps the body expel mucous, which helps get rid of colds faster. Rosemary oil can therefore help you get over a cold more quickly if used as a method of cold relief.

According to Valerie Ann Worwood, the author of The Complete Book of Essential Oils and Aromatherapy, a blend of rosemary, lemon and eucalyptus oils can massaged into the facial sinus areas, including bridge of the nose, cheekbones, temples to relieve sinus congestion and speed healing from a cold virus.

2) Clary Sage Oil as an Immune Booster

Clary sage essential oil is antidepressant, anticonvulsive, antispasmodic, antiseptic, aphrodisiac, astringent, bactericidal, carminative, deodorant, digestive, emmenagogue, euphoric, hypotensive, nervine, sedative, stomachic and a tonic for the uterus.

Clary sage oil is notorious for being a hormone balancer. In addition to this, it also imparts relaxation and healing to the entire body. It is a much safer option that regular sage oil, which is known to an excitant that is potentially toxic and can trigger miscarriage and epileptic seizures. 

Clary sage oil offers anti-inflammatory benefits that will help an over-active immune system return to a balanced state, so that your body will have an easier time getting over cold and flu germs. And with expectorant–disinfectant and antibacterial activity to boot–you will be greatly boosting your body’s infection fighting ability when you add powerful sage to your arsenal of essential oils for immune health.

3) Thyme Oil as an Immune Booster

Thyme oil is possibly the most powerful of the essential oils known to fight germs. In fact, the ingredient “Thymol” which appears in environmentally friendly cleaning products is a chemical derivative of thyme oil. 

Thyme oil is known to be antispasmodic, antirheumatic, antiseptic, bactericidal, bechic, cardiac, carminative, cicatrisant, diuretic, emenagogue, expectorant, hypertensive, insecticide, stimulant, tonic and vermifuge.
