Mario Paonessa, 49, physical instructor in a Milan high school, has a rather unenviable routine at the Arya Vaidya Sala at Kottakal, 40 km from Kozhikode in Kerala. His Rasayana treatment at the 93-year-old Ayurveda treatment centre involves imbibing quantities of special ghee for the first week. After this there's a steam bath routine for another week, followed by 14 days of oil enema and finally three days of sucking oil through the nose. All this before he gets to the stage where he can graduate to special herbal tonics.
