My question is why the second procedure gives a way better yield. The only way I could achieve any separation in layers of distillate at all, getting
essential oil from myrrh resin, was to heat a saturated salt solution, leading the overheated steam through the solid.
I could not obtain any yield of oils from orange peel powder by just heating it directly with water, either.
