PATCHWORK

Natural Patches of Vermont ($7.50 each, at natural patchesofvermont.com), at the Sense Spa at Rosewood San Miguel de Allende in Mexico, attempt to prolong that posttreatment sensation. These small pieces of adhesive cloth are saturated with essential oils and extra-virgin olive oil; spa therapists usually apply them to the body and face at the beginning of a treatment. Spa director Paulina Mercader says that the patches send positive impulses to the brain as you inhale them, and their effect can last for up to 24 hours. They can be tailored to your needs, such as camomile for headaches and tension or lavender for repose.
