Lemon essential oil is simple and unassuming, but so useful, and at the moment it seems to be everyone's favourite.

The horses surprised me by selecting it this weekend when I was demonstrating self-selection during a workshop here. Ellie chose it first, then her daughter and brother joined in, till they were all standing around in a trance. Then I was working with  a Level 2 student, teaching meridian assessment and oil selection, and lemon came up again for her dog with warts.
