Essential oils are potent, concentrated oils extracted naturally from various plants. They are often used in aromatherapy, and massage therapy, and are occasionally taken orally. Essential oils can be used to treat emotional problems such as depression, anxiety, sleeplessness, and lethargy. They can also be used to treat medical problems such as poor circulation and respiratory issues. Additionally, they are used in cosmetics to treat dandruff, acne, and other skin conditions. Essential oils are great because they are powerful in small doses, making them easy to carry. Although they are powerful many essential oils can be used therapeutically without professional assistance, making them cost efficient and convenient.
