Abstract: The invention relates to a method for processing freshly picked plants, and more particularly aromatic herbs or plants, characterized in that it comprises steps consisting in adding water activity depressors to consumable pieces of plants and mixing them; deep-freezing the resulting mixture; extracting from such mixture an amount of water determined by sublimation and stopping the process at the very beginning or during progress of the primary desiccation, so that such mixture has dry and/or still frozen or more or less moist pieces of plants; homogeneously mixing the resulting mixture of pieces of plants so as to allow for a migration of water from the frozen pieces towards the more or less moist pieces and/or the dry pieces.
