Sulphur, Mercury & Salt

The Three Principles of the Alchemist

To the alchemist, a plant was never simply a plant.

Hidden within it were different principles. Some volatile, some fixed. Some revealed through distillation, others only after the plant had been reduced to ash.

The work of alchemy was to separate these principles, purify them, and bring them together again.

Within the Paracelsian tradition, these became known as the Tria Prima: the three philosophical principles of Sulphur, Mercury and Salt.

They are central to understanding spagyrics, and they offer a very different way of looking at the plants we work with.

The Tria Prima

When an alchemist spoke of Sulphur, Mercury and Salt, they were not necessarily speaking about the ordinary substances we know by those names.

They were philosophical principles used to understand the nature of matter.

Everything contained something volatile, something combustible or characteristic, and something fixed.

These became Mercury, Sulphur and Salt.

Within plant alchemy, they are often described more poetically as Spirit, Soul and Body.

And although they exist together within the living plant, the alchemist seeks to separate them.

This is the beginning of the work.

Mercury - The Spirit

Mercury is the volatile principle.

It rises.

It moves.

It escapes.

In spagyric plant work, Mercury is traditionally associated with the spirit of wine: alcohol produced through fermentation and purified through repeated distillation.

It is the carrier. The menstruum. The subtle spirit capable of extracting and holding what would otherwise remain within the plant.

Mercury has always occupied a strange position in alchemical thought.

Neither entirely fixed nor entirely fleeting, it moves between states and crosses boundaries. This made it a powerful symbol of mediation and transformation.

The spirit moves where the body cannot.

Sulphur - The Soul

Sulphur is the individual character of the substance.

Its colour. Its aroma. Its oils. Its particular nature.

Within plant alchemy, philosophical Sulphur is associated especially with the plant's essential oils and other oily, combustible principles.

If Mercury is what carries, Sulphur is what gives the plant its distinctive expression.

Rose does not smell like frankincense.

Frankincense does not behave like rosemary.

Each plant possesses its own particular signature.

The alchemist called this principle Sulphur.

It was sometimes understood as the soul of the substance. The part that gives matter its individual character.

Salt - The Body

Then there is what refuses to disappear.

The fixed.

The body.

After a plant has been extracted and its volatile principles removed, the remaining plant matter is burned.

It blackens.

It becomes charcoal.

Eventually, under sustained heat, it is reduced to pale mineral ash.

This ash contains the plant's mineral salts.

Through the traditional spagyric processes of calcination, dissolution, filtration and crystallisation, these salts can be purified.

What appears at first to be waste becomes part of the preparation again.

This is one of the aspects of spagyrics that we find most beautiful.

Very little is simply discarded.

Even after the plant has been exhausted, burned and reduced almost to nothing, something remains.

Salt.

The fixed body of the plant.

Separate. Purify. Reunite.

And this is where the alchemical process becomes something more than extraction.

The plant has been divided.

Its spirit separated.

Its soul revealed.

Its body reduced to ash and purified.

But separation is not the end of the work, the principles must be reunited.

Solve et coagula.

Separate and recombine.

The purified salts are returned to the preparation, bringing the fixed and volatile principles together once again.

The plant returns, but not exactly as it was before.

It has passed through fire, dissolution, purification and reunion.

A Different Way of Seeing a Plant

Whether we understand Sulphur, Mercury and Salt literally, philosophically or symbolically, the Tria Prima asks us to look at matter differently.

A plant becomes more than something from which we extract useful compounds.

It becomes something that can be opened.

Separated.

Examined.

Purified.

And reunited.

Perhaps this is why plant alchemy feels so different from simply making a tincture.

There is an intimacy in taking a plant apart and following each part through its transformation.

The volatile rises, the oils reveal themselves and the body meets the fire.

And eventually, what was separated is brought together once more.

Spirit. Soul. Body.

Mercury. Sulphur. Salt.
