There are 2 types of spagyrics, I only do calcining and adding the white ash back into the tincture, to add the earth element (minerals) into the tincture . The full spagyric process destroys many constituents , and at the soma time increases some constituents like essential oils.
I don’t see subtle properties, I see the addition of the plants mineral content which is very important for many (not all) medicinal plants.
I am not familiar with Ens
I’m very passionate about the alchemical work and would love to hear the experience of someone with a depth of understanding in plant work such as yours.
We will discuss this further in our Pao Zhi class (in February I think)
