Some important facts about aromatherapy...

Aromatherapy is the therapeutic use of essential oils.  It is a natural approach to healing and an alternative to the current emphasis on prescription and over the counter medications.
 
Essential oils are recognized by their antibacterial, antioxidant, anti fungal, antiviral and anti-inflammatory properties.  They are effective in the treatment of many infections and respiratory conditions.  They can improve immune function and response and help balance the nervous system.
 
While "aromatherapy" candles, bath gels and lower grade oils can have a pleasant fragrance and we can enjoy using them, very few (if any) will have any true therapeutic value or effect on the body. 
 
True therapeutic essential oils are of a much higher quality than the commercial grade oils used by perfume companies and the fragrance industry.  Only raw, pure, therapeutic grade essential oils, that have been grown, harvested and distilled in the right environment specifically for this purpose, will have the healing properties we desire in an essential oil.
 
Re-distillation is routinely performed by perfume and fragrance industry to get a more favorable scent, but this adversely affects the therapeutic quality of the oils.
 
Because pure, therapeutic essential oils do have a physiological, a psychological and a pharmacological effect on us, it is important to be aware of and to follow responsible cautions when using therapeutic essential oils.
