In Biblical times, a great assortment of essential oils were used for healing, medicines, ointments, anointing, sweet savors, odors, spices, incense, perfumes, oils of joy and gladness, given as gifts, embalming, and offered as sacrifices. The people of the time knew what each oil was for and how to use them, which isn't always depicted in the Bible. It would be like writing a story about modern Christianity today and including the uses of aspirin, which are common place and wouldn't need to be explained. The same holds true with the oils of the Bible, they were so much a part of the lives of everyone that no explanations were necessary.

Essential oils perform many duties in plant functions. They regulate plant growth, help in plant metabolism, and provide the basis for the plant's immune system, warding off undesirable viruses, bacteria, microbes, fungi, parasites, and insects. When a plant is cut, it bleeds the oleo gum resin into the wound which initiates healing. Because God created the plants for us, their oils can serve many of the same purposes for us. They support and balance our endocrine, circulatory, digestive, nervous, and reproductive systems. They clear our sinuses and lungs to help us breathe better. They help us metabolize our nutrients, minerals, and vitamins. They also boost the natural defenses of our immune systems so we can fight off disease by our own abilities. And while they are friendly to us, they can be hostile to bacteria, viruses, parasites, and fungi. As if the foregoing were not enough to demonstrate the amazing abundance of healing properties of essential oils, they are also the world's most powerful antioxidants that gobble up free radicals in our bodies.
