Conventional deodorants are bad news for your health and for the environment. Deodorant works by killing bacteria. It's not sweating that makes you smell. It’s that your armpits are a warm, dark place, and when you sweat you’re basically creating an ideal environment for bacteria to thrive. Unfortunately, conventional deodorants use nasty chemicals to do that!
Studies have shown that the essential oil of lavender, is renowned for its antibiotic properties and not only smells wonderful it has a variety of therapeutic and curative properties.
A great reason to use tea tree oil is to eliminate body odour. Tea tree oil has antimicrobial properties that destroy the bacteria on your skin that causes body odour.
Since some people have a skin reaction to certain oils, test the underarm area or a small patch of skin before using. Delightfully fragrant, sage can fight bacteria and reduce perspiration.
Just a few drops of essential oils will do the trick when making a homemade deodorant recipe, where something less powerful like lavender takes 15-20 drops. My advice when getting used to essential oil is to start small. Add a few drops, mix, smell, repeat. You can always add more.
