never heard jasmin oil can obtained by distillation. the aroma will be distroyed by the heat. I remember if the oil is extracted directly by commercial ethanol (a harsher process than the second method), then it is cheap, but good enough to be used in a burner; if it is absorbed first by plant oil like olive oil, then extracted by pure ethanol, it is considered safer,purer, more complete aroma, and of course more expensive.
