An oil carries the mark of where it grew: altitude, rains, cultivar, distillation. Bulgarian and Turkish Damask rose oils differ; Vietnamese cassia and Ceylon cinnamon are two species.
The fifteen pages below record the key producing regions for aromatic materials: which plants, which season, which part is distilled, the main constituents, geographical indications and notes on provenance. Harvest timing for every region is collected in the Harvest calendar.
