It is only in recent years that aromatherapy, or essential oil therapy, has gained substantial acceptance; this is primarily due to French veterinarians who have begun using essential oils and hydrosols in their practices. Laypeople, of course, have been enjoying great success treating animals with the very same substances for many years; for it is not just the medical professionals who can safely and effectively administer these aromatic oils. Anyone enabled with quality essential oils or hydrosols and adequate knowledge can use a plant's most concentrated and energetic byproducts to improve the health of their animals, and treat and prevent various illnesses and common ailments. Aromatherapy is actually a science that has a much larger archive of supported scientific data than most other holistic care methods. However, most of these studies were originally published in French or German.
