the extraction of soluble parts of a drug by passing a solvent liquid through it.
percolation (perˈ·k
·lāˑ·shn),n a method for extracting essential oils from aromatic plant materials that strongly resembles steam distillation. As part of the process, a generator above the aromatic plant material produces steam. The steam then trickles down into the aromatic plant material, and the steam and oil are collected in the exact method used in steam distillation. This process is quicker and less complex than steam distillation. Also called
hydro-diffusion. See also steam distillation.
