A 100% pure essential oil is not made with any synthetic chemicals. The term “essential oil” means that this oil is the very essence of the plant it was distilled from – it is the plant in its purest form, and made from nothing else. Essential oils are used in a wide variety of aromatherapy practices. Tea-tree oil can be used for cleansing and protection. It is particularly useful for warding off the demons of disease and can be used for healing rituals and as a room aroma in a sickroom. It is decongestive and may help to clear energy blockages.
