Most of your essential oils state to dilute in water or a carrier oil. Is there a "generic" carrier oil which harmonizes with any of the essential oils or is there specific carrier oils for each essential oil? Also, if diluted with water, is it intended to be applied to the specific treatment area such as those which reduce digestive symptoms & complaints? Where on the your body do you spray for those intended to treat depression,anxiety, and stress?

Most aromatherapists use sweet almond oil or jojoba. In water, the blend can be applied to unbroken skin anywhere. With digestion and some other ailments, we do like to apply the blend on or near the site . For anxiety , depression and stress, I like to apply or spray on the neck, temples or nape of the throat..

 Thank you, very good questions
