Essential oils are distilled from the leaves, roots, bark and other aromatic portions of a plant/botanical. These oils evaporate, and have a concentrated aroma. Fixed oils (Carrier Oils: Coconut oil, Almond oil) are pressed from the fatty portions of a plant or botanical, such as the seeds, nuts or kernels. We pre-blend all of our natural oils with your choice of carrier oil. They are sold in 1ml or 2ml glass amber jars with rollers. You can also use as a vapor, oils can be mixed with vegetable glycerin and diffused in a diffuser. Just add it to a vaporizer with your water and sit in an enclosed area. It can also be sprayed in a shower/sauna for a similar effect. You can even add a few drops to a bowl of hot water and breathe in the fumes.
