The plant parts are sterilized and placed in the sachets, then some ghone rocks are placed in the container with them. The container is sealed and then subjected to a dissociation wave that breaks down the structure of living matter in the container. The ghone stones react to this wave too by breaking apart and freezing the contents of the container. The cost of this storage method probably accounts for a tenth of the total cost of production.
The alternative to storing them will be to convert the materials to pills but the need to preserve their purity makes items with life energy difficult to work with and can be more expensive. The advantage of pills is their quick-acting properties. As they are right now, the materials will be eaten raw. The advantage of that is the high utility per unit of the materials while the disadvantage is that they will need to be digested which takes more time.
