Spagyrics Explained: Paracelsus and the Tria Prima
Spagyrics is alchemy's most practical legacy: not gold, but a way of processing medicinal plants that takes them apart and puts them back together. The word turns up on small dropper bottles in natural-food stores and in the reading lists of American alchemy circles, and almost nobody explains what it actually means.

Spagyrics is an alchemical method of processing medicinal plants. The word first appears in Paracelsus (1493–1541) and comes from the Greek spao, to separate, and ageiro, to unite: the plant is broken into its parts, each is treated separately, and they are recombined. Typical steps are fermentation, distillation and calcination, burning the residue to ash, before distillate and ash salts are reunited. The most widely used method today goes back to Carl-Friedrich Zimpel (1801–1879), who developed it from 1868. In the US, spagyric remedies are usually sold as homeopathic drugs; the FDA has approved no homeopathic drug as safe and effective, and an effect beyond placebo has not been shown. Distilling alcohol at home without a federal permit is illegal.

This article covers where the word comes from, what Paracelsus's three principles — salt, sulfur and mercury — stand for, how a spagyric essence is made step by step, how it differs from a tincture, who invented the method in use today, and what the law in the United States says about the bottle. What it does not give you: a recipe for home production, or any promise of healing. Spagyric products are sold as homeopathic drugs, and their effectiveness is not established.
Separate and unite: where the word comes from
The term first appears in the writings of Paracelsus, the Swiss physician Theophrastus von Hohenheim (1493–1541), who pulled alchemy away from gold-making and toward medicine. It is built from two Greek words: spao, to separate, and ageiro, to unite.
That is not wordplay; it is the method. Whoever works spagyrically breaks the plant down, treats each part separately and then brings them back together. The idea behind it: only separation reveals what was woven together before, and reunion should yield something more than the sum of its parts. The same movement is described in a line of the Emerald Tablet: separate the subtle from the gross, gently and with great care.
Salt, sulfur, mercury: the three principles
Paracelsus assigned every substance three principles, the tria prima. They are not chemicals in the modern sense but roles — what in a thing is fixed, what burns and what is volatile.
| Principle | Stands for | In the plant |
|---|---|---|
| Sal · salt | body, the solid, what remains | the mineral salts left as white ash after burning |
| Sulphur · sulfur | soul, the combustible, character | the essential oil — the scent that makes a plant unmistakable |
| Mercurius · mercury | spirit, the volatile, what binds | the alcohol produced by fermentation, the carrier |
Read it once like this and the process explains itself: each principle is recovered with the means that suits it — the volatile by distillation, the fixed by fire.
How a spagyric essence is made
Methods differ in detail, but the basic sequence is the same everywhere. Four steps, and the third is where the real difference from ordinary herbal preparation lies.
- Fermentation — the fresh plant is set with yeast, sugars become alcohol. This is the mercury.
- Distillation — alcohol and essential oil are drawn off. This is the sulfur.
- Calcination — the residue is dried and burned down to white ash, and the salts are extracted. This is the salt.
- Reunion — distillate and salt solution are combined and left to mature. The essence is finished.
Step three is the decisive one. In ordinary herb work, the spent plant material is waste; here it becomes the source of the "body." That is also where spagyrics makes its biggest interpretive claim — that the ash preserves "what endures" of the plant. That cannot be measured. All anyone can establish is that mineral salts remain.
The second step, in a bottle
Peppermint Essential Oil
An essential oil is exactly what the spagyrists called sulfur: the distilled character of a plant. If you want to understand the tria prima with your senses rather than a still, open this bottle and you are holding step two. Certified organic, 100% pure and undiluted. It is not a spagyric essence and not a remedy, and we make no health claims for it. Never take essential oils by mouth, dilute before skin contact, and keep the bottle away from children and pets — cats in particular. $20.00

Retail labels mix the terms freely, so here they are side by side.
| Tincture | Spagyric essence | |
|---|---|---|
| Basic process | steeping in alcohol | fermenting, distilling, burning, reuniting |
| Alcohol | added from outside | produced by the plant itself |
| Plant residue | discarded | burned to ash and returned |
| Time | weeks | weeks to months |
| Doable at home in the US | yes — here is how | no — distilling alcohol requires a federal permit |
| Legal status of retail products | depends on the claims made | typically sold as homeopathic drugs |
From Paracelsus to Zimpel
Three hundred years lie between the word and today's method. Paracelsus supplied the name and the model, but no single standard procedure. That changed in the nineteenth century.
Carl-Friedrich Zimpel (1801–1879) was a railroad engineer before he studied medicine — a biography you can see in the method. In Italy he met Count Cesare Mattei, whose "electro-homeopathy" was widely popular at the time. From 1868 Zimpel developed his own system, combining Paracelsian procedures with homeopathic thinking. He regarded distillation as the crucial step and greatly extended it.
The Zimpel method is still the best known; other procedures differ in the details of fermentation and calcination. Whoever holds a bottle is not holding "spagyrics" as such but one particular method — and it is usually named on the label.
The American chapter: an alchemy school in Salt Lake City
Spagyrics has an unexpected US history. In 1960 Albert Richard Riedel (1911–1984), writing as Frater Albertus, founded the Paracelsus Research Society in Salt Lake City, Utah, and published The Alchemist's Handbook. His classes taught what he called "practical alchemy," with the preparation of a plant stone and spagyric tinctures at its center. For decades his students formed the backbone of laboratory alchemy in North America, and much of what English-speaking hobbyists read about the tria prima still traces back to that small school. For the wider tradition, see spiritual alchemy explained.
What the law says about the bottle — and what it doesn't
This is the soberest section and the most important. In the United States, spagyric remedies sold as medicines are usually marketed as homeopathic drugs, prepared according to the Homeopathic Pharmacopoeia of the United States (HPUS). The Food and Drug Administration states plainly that it has not approved any homeopathic drug product as safe and effective; its 2022 guidance says it will prioritize enforcement against products that pose particular risks.
The Federal Trade Commission added a second layer in 2016: an over-the-counter homeopathic product that claims to treat a condition must back that claim with the same competent scientific evidence as any other health claim, or say clearly that the claim rests on homeopathic theory and not on modern science.
None of that is a judgment for or against the practice. It only means that anyone using these products should know on what basis they sit on the shelf. When a seller names an indication, that is the seller's statement, not the result of a regulatory review.
Practically: how to work with this
Don't distill at home. Producing distilled spirits in the United States without a federal permit from the Alcohol and Tobacco Tax and Trade Bureau is illegal, even for personal use and even in small amounts. Small stills are also a fire hazard in a kitchen.
Start with a tincture. If you want the principle in your hands, make a clean herbal extract and note ratio, date and steeping time. It is the first step everything else assumes.
Note the harvest. Any method is only as good as the herb that goes into it — see when to harvest and dry herbs.
Read the method on the label. The procedure named there tells you which production route is meant.
With symptoms, see a doctor first. A homeopathic product without FDA approval does not replace a diagnosis, especially for anything new or persistent.
Keep the levels apart. The three principles are a sixteenth-century model and a beautiful way to look at a plant. They are not a statement about what happens in the body.
Temple tip: practice the three principles on one plant
Take a handful of fresh lemon balm and walk through the tria prima without making anything. The scent between your fingers: sulfur. The sap that comes out when you crush a leaf: mercury. The skeleton of stem that remains when everything else is gone: salt. It takes two minutes and changes how you look at a plant — no flask required.
Voices from practice
Personal accounts from herbal practice — experiences, not evidence:
- "Step three floored me. For years I threw the spent herb on the compost without ever asking what was left in it."
- "The first time I read the FDA line about homeopathics I was annoyed. Now I think it's the most honest sentence on the whole shelf."
- "The tria prima became an observation grid for me. Whether it's true is another question — but I see more in a plant now."
What we don't promise
- That spagyric remedies work. Effectiveness beyond placebo has not been shown.
- That the ash preserves the plant's "powers." That is an interpretation of the process, not a measured quantity.
- That you can rebuild the process at home. Distilling alcohol requires a federal permit.
- That a product labeled HPUS has been tested for effectiveness. The FDA has approved no homeopathic drug.
What remains: one of the most carefully thought-out craft procedures alchemy ever produced — and a way of thinking about plants that has held for five hundred years.
Frequently asked questions
What is spagyrics?
An alchemical method of processing medicinal plants: the plant is broken down by fermentation, distillation and burning to ash, then put back together. The term first appears in Paracelsus.
What do salt, sulfur and mercury mean?
Paracelsus's three principles: salt stands for the fixed and is found in the ash salts, sulfur for the combustible and is found in the essential oil, mercury for the volatile and is found in the alcohol from fermentation.
What is the difference between a tincture and a spagyric essence?
A tincture steeps the herb in added alcohol and discards the residue. In a spagyric essence the alcohol comes from fermenting the plant itself, and the residue is burned and returned.
Who developed today's method?
Carl-Friedrich Zimpel (1801–1879), from 1868, after meeting Cesare Mattei in Italy. He combined Paracelsian steps with homeopathic ideas and placed special weight on distillation.
Are spagyric remedies FDA approved?
No. In the US they are usually sold as homeopathic drugs, and the FDA has not approved any homeopathic drug as safe and effective.
Can I make spagyrics myself?
Not the full process: distilling alcohol without a federal permit is illegal in the United States. The first step, a well-made herbal tincture, is easy to do at home.
