A process for preparing a total extract which is a mixture of a fresh plant matter with a fatty matter includes a. contacting the fresh plant matter which comprises at least 10% of water by weight relative to its total weight before or after desiccation loss, with the fatty matter chosen from hydrogenated oil or fat at a temperature between 50° C. and 180° C.; b. grinding the plant matter-fatty matter mixture at said temperature between 50° C. to 180° C.; and c. recovering a total extract that is solid or liquid at ambient temperature with a concentration of less than or equal to 4% of water by weight relative to the total weight of the total extract. Extracts recovered from such process and treatments using the extracts are also disclosed.
