Our Process

Separate, Purify, and Recombine

Every extract we make follows the spagyric method, a three part process that comes from traditional laboratory alchemy. We separate each mushroom into its parts, purify them, and bring them back together in one bottle.

Body, Soul, and Spirit

The word spagyric is usually credited to Paracelsus, the 16th century physician and alchemist. It comes from two Greek words: spao, to separate, and ageiro, to gather or bring together.

Alchemists described every plant and mushroom as having a body, a soul, and a spirit. We separate those parts through extraction, purify the mineral salts from what's left behind, and then bring everything back together. Most tinctures keep only the liquid and discard the rest. A spagyric returns all of it, so what's in the bottle reflects the whole mushroom.

How We Make It

From Whole Mushroom to Finished Extract

Every batch is made by hand, start to finish, in our cGMP certified facility in Estacada, Oregon.

Step 1

Whole Fruiting Bodies

We start with 100% mushroom fruiting bodies, all domestically sourced. Some are wild harvested and some are cultivated by growers we've worked with for years.

Step 2

Alcohol Extraction

The mushrooms go into our Soxhlet extractors with cane alcohol under gentle heat, drawing out the alcohol soluble compounds and the subtle aromatics.

Step 3

Water Extraction

Next comes a hot water extraction for the water soluble compounds, including polysaccharides like beta-glucans. The Soxhlet is a closed system, so the volatiles stay in.

Step 4

Mineral Salts

We draw the mineral salts out of the spent mushroom material, purify them, and return them to the extract. This is the step that makes it spagyric.

We look at the laboratory and the flask we work in as the microcosm that mirrors the macrocosm, the below that mimics and captures the above. In this way, the vital force that would otherwise return to the firmament is captured within the universe of our flask.
