个人感觉英文的描述更为详细一些，以下资料来源于国外某精油品牌的部分说明...


** c.org: Certified organic farming - No use of chemical fertilizers, herbicides, pesticides, fungicides. Distillation usually under low pressure. No overheating, slow distillation in order to preserve the maximum of active components in the essential oil which contribute to its special aromatic effect and healing power. Lack of these ingredients has a different rate of evaporation when exposed to heat. If an oil is distilled too quickly (high pressure, high temperature), many of these precious elements preserved by a slower evaporation rate are lost.

The process of manufacturing pure organic essential oils, which requires more time and involves higher risks, is usually only practiced in a few small family enterprises. As a result, the organic essential oils are more costly than those of conventional farming. Most of our certified organic products are controlled by the following organizations:

Nature et Progress (France) * Simples (France) * Demeter (Germany) * Suolo e salute (Italy) * Agrobio (Portugal) * Vida Sana (Spain) * CRAF (Spain) * Biotop (Israel).


** trad: traditional farming - Like c.org. no use of chemical fertilizers, herbicides, pesticides, fungicides. Distillation usually under low pressure. No overheating, usually slow distillation. The farmer is not a member of one of the controlling organizations, but planting, harvesting and distilling are performed according to the old traditional methods without any use of chemical substances. Because of our close personal contact with these farmers we are able to monitor their work and feel confident that no chemicals are used in the cultivation of plants and manufacturing of their essential oils.


** wc.org: wild certified organic - 'This category applies to oils stemming from wild-grown plants, harvested and distilled according to c.org. regulations. Their manufacturing does not differ from that of c.org. oils.


** wild: wild-grown - These essential oils stem from wild-growing plants. They may be manufactured in larger quantities (e.g. Eucalyptus, Tea Tree, Pine sib. etc.) but have not undergone chemical treatment.


** S: selected farming - The Ayus collection also contains essential oils from many countries where it is impossible to find c.org. sources, since control organizations, or independent monitoring agencies do not exist there or are not applicable (e.g. Bergamott in Calabria). Each of these oils, however, is carefully selected for its high quality. The regular use of gas chromatography testing provides a further guarantee of purity and quality.
