Maceration

Cold extraction by prolonged soaking of the plant material in a liquid (water, oil or alcohol depending on use), without heat. The longer contact time than an infusion extracts compounds that cold water alone would dissolve too slowly.

Process summary

1) Chop or crush the plant material. 2) Fully submerge it in the chosen liquid, in a closed container. 3) Let it sit in a cool, dark place, stirring occasionally, for anywhere from several hours to several days depending on the preparation. 4) Strain and use the resulting liquid.
