The production of menthol crystals starts with extracting menthol from mint plants. Steam distillation is one of the various methods available where crushed mint leaves are passed through steam to vaporize the menthol, which can then be condensed and collected back. Other methods include solvent extraction techniques. Further steps like crystallization and distillation ensure the refinement level is set to the required target of quality and purity standard of menthol crystals. Crystallization is one way of doing so, where the menthol solution is cooled to a level where it can become crystalized and once that happens, it is separated and dried.
