Making an Ens is a very different process then a spagyric tincture. One uses three components, Potassium carbonate saturated with moisture form the night air. This is called Tartar water or volatile Salts, fresh plant matter and pure alcohol around 98 % pure. The collection of tartar water is a long process since one makes layer of this salts on a plate and put it outside in the night preferable in the Spring time. I use different dishes. One should collect 1L at least. Also one needs at least 1L of pure alcohol that can be used to extract the Ens from the solvent (Tartar water and fresh herbs). I made several of these Enses and making these tinctures is an initiation in itself. It digs deep in ones inner worlds as well in the outer world. Ans Ens is the quintessence of ‘Q state’ of the plant. In the link I post here you can read about the formal process of making a Premum Ens Melissae. Every fresh herb can be used to make an Ens.
