Pure essential oils are easily available, either as single essences or in ready-made mixtures. It is worth investing in a few of these. Some of their many uses include being used as scents in bathing, added to base oils for massage, rubbed into the palms and breathed in to help focus and added to a candle or burner to energise a room.
Some of the most useful oils are also some of the least expensive. If you are starting out, lavender, rosemary, neroli, geranium and other easily found and inexpensive oils are a good place to begin. A few drops of each will work wonders in many situations. Keep a very small bottle of lavender and rosemary with you when you travel. Aside from getting rid of smells and energising a space, one or two drops rubbed on the palm of your hands, will act as a very good calming agent in times of stress or panic and even young children can benefit from the calming effects of a drop of this. Eucalyptus, cypress, and other woods added to the bath or onto a tissue, is great for stuffy noses after a day in the traffic. The delicious and more expensive oils can be added slowly later.
Single essences are always best and you can make your mixes. Here are some mixtures that could be used in a sensuous bath or massage oil. A few drops of these same mixtures can go into the bath or be added to a small bottle of base or carrier oil like Almond or Grapeseed, to be used as massage oil. Numbers refer to drops. You need less than you might think. Try experimenting with different permutations.
Any decent basic aromatherapy book will give you more details and mixes.
