Expensive spa treatments typically include exotic ingredients, but the local food movement has contributed to the new treatment trend of fruits and herbs from local farms. Guests at the Ojai Valley Inn in California can get scrubbed with Pixie tangerines.  Spa Hotel Healdsburg features the same wine, honey, and Meyer lemons found in its restaurant.  As often is the case, don’t expect local to equate to cheaper prices than the exotic stuff.
