Essential oils are concentrated oils derived from plants and are known for having plant essences, which they get through the distillation process. They smell great, help reduce stress & treat fungal infections, and induce sleep. Their existence date back a thousand years ago, and since then, they have been used extensively for medicinal purposes. However, essential oils, nowadays, are used less for medical purposes and more for skincare, aromatherapy, & alternative healing practices. They can be extracted from almost any plant substance, like flowers, tree bark, etc. Some of the most commonly used essential oils available in the market include tea tree, rosemary, lavender, eucalyptus, and citrus, among many others.
