Essential oils are the essence of a plant. They are made from the bark, stem, leaves, roots or flowers of a plant, using a process of steam distillation. They play a role in protecting plants and helping with pollination, but they also bring us plenty of benefits. They have been used for many years in cooking, beauty treatments, and medicines.
Essential oils give plants their unique aroma and that is what makes them so effective in aromatherapy. The aroma acts on the smell receptors in the nose, which are closely connected to a part of the brain which governs memory and emotions. This is why essential oils are used to affect mood.
Essential oils can be used in a blend or complementary oils, or they can be used on their own, depending on the desired.
