Based on these photos, it's not clear what the final Spa recipes are, but a month ago, FarmVille Community Manager Lexilicious said they would be the following:
* Fresh Sachet – Pumpkins, Cranberries, and Sunflowers
* Floral Perfume – Raspberries and Morning Glory
* Soothing Herbal Lotion – Aloe Vera and Green Tea
* Relaxation Oil – Blueberries and Morning Glory
You will also be able to upgrade your FarmVille Spa, using coins or 15 Farm Cash. The higher your spa's star rating, the more tables will be open for crafting. Below are pictures of the FarmVille Spa in its beginning stages and then when it's completely upgraded.
