Essential oils are concentrated plant extracts with a wide variety of health benefits. They can boost your immune system, relieve stress and anxiety and help you sleep better.
But more research is needed on their safety and effectiveness. And because there’s no standardized grading system, quality can vary widely.
Tea Tree Oil
Tea tree oil, distilled from the leaves of the Australian native Melaleuca alternifolia, has germ-fighting properties. Its star ingredient is terpinen-4-ol, which destroys certain bacteria and fungi.
The Aboriginal Bundjalung people were likely the first to use this natural antiseptic. They used crushed leaves to treat infections, insect bites, and skin problems.
Now you can find it in a wide range of skin and health care products. Some researchers suggest it may relieve allergic skin reactions, such as contact dermatitis, by reducing swelling. It is also thought to be effective against herpes simplex. Don’t ingest it, though—that can cause confusion, loss of muscle control, breathing problems, and coma. (1,2)
Peppermint Oil
Known for its high menthol content and invigorating aroma, peppermint oil may ease indigestion, aid digestion, soothe headaches, relieve sinus congestion, and soothe skin irritation. It has also been shown to reduce nausea, including in patients undergoing cancer treatment.
This powerhouse herb has antibacterial properties. In one study, peppermint oil and several of its constituents inhibited the growth of Helicobacter pylori, Salmonella enteritidis, and methicillin-resistant Staphylococcus aureus.
The oil can be taken orally as a capsule or dietary supplement, but make sure to talk to your doctor before trying it. You can also diffuse it for an invigorating aroma or apply it topically to the skin, though make sure to follow dilution guidelines, as too much peppermint oil could be irritating. You can even use it in a shampoo to stimulate the scalp and remove dandruff.
Lavender Oil
Lavender is a versatile plant that is often used in aromatherapy. Its soothing, floral scent has been shown to reduce anxiety and improve mood. It also promotes relaxation, which can help improve sleep.
When applied to skin, lavender oil can soothe irritated or damaged tissues. Studies have shown that it may accelerate wound healing and boost collagen synthesis.
Its antifungal properties are effective at warding off common fungal infections, including yeast infection and athlete’s foot. It can be inhaled or applied topically as a natural alternative to Neosporin.
As with all essential oils, it is important to dilute the lavender oil before applying it directly to the skin. It is not recommended for use with infants or young children, and should always be diluted before using around the eyes.
Rose Oil
Known for its soothing properties, rose oil can help ease feelings of stress and depression. It also has been shown to increase libido by stimulating the hypothalamus gland.
It’s been found that the oil can also relieve menstrual pain by decreasing primary dysmenorrhea (pain that occurs during your period without any other underlying cause). A 2024 study found that inhaling or massaging rose essential oils can reduce PMS symptoms including nausea, vomiting, abdominal discomfort and headaches.
It’s best to use only pure rose oil that is steam-distilled and comes from a reputable supplier that grows its own roses in regions like Bulgaria, Turkey or Morocco for optimal quality. This ensures that the oil is free of additives and pesticides. Also, look for dark blue or amber bottles since light can damage the oil over time.
Lemon Oil
Lemon oil is derived from the peels of lemon, a citrus fruit native to warm, frost-free climates. It has a bright, zesty scent that is refreshing and uplifting.
Used in skin care, it helps clarify and tone the complexion. In addition, it acts as an antimicrobial and astringent to shrink pores, reduce inflammation, soothe skin and ease blemishes. It can also be added to hair products to boost scalp health and promote strong, healthy-looking hair.
Lemon Oil is phototoxic, so it should not be applied to the skin without dilution in a carrier oil or lotion. Its energizing and balancing properties help to stimulate the immune system, which can strengthen your body against harmful infections. It also promotes healthy liver and kidney function. Its vitamin content can reduce oxidative stress and help protect against damage.
