There are a wide variety of Essential oils and these have remarkable qualities that enhance health, beauty, and well being. Not to be confused with fragrant oils which are combinations of synthetically manufactured chemicals are designed to "mimic" the aroma of natural materials.
Essential oils are distilled from plant material using water, steam or both. The process involves placing plant material over a grate and forcing steam through the grate. In the alternative, the plant material can be placed in boiling water. In either case, the heat from the steam and/or water causes the plant material to break apart and release an aromatic vapor. This vapor is condensed through cooling tubes into liquid form. This liquid is partly the essential oil of the plant and partly the hydrosol (water) of the plant. The essential oil and hydrosol are then separated from one another and bottled. Different essential oils product different results in different persons with different skin types
