Medicinal mushroom extracts may be dietary supplements and are not a substitute for a balanced and varied diet. Do not exceed the recommended daily dose. Methylene blue is a laboratory chemical and is not intended for ingestion.
From forest to bottle
Five steps.
Nothing
in between.
01
Wild harvesting
02
Ultrasound
03
Ethanol + hot water
04
Lab testing
05
Bottling
Step 1 / 5
Wild harvesting
We hand-harvest Tinder Fungus and Birch Polypore in German forests. Only fruiting bodies are used, not mycelium.
Fruiting bodies only
Step 2 / 5
Ultrasound
The mushrooms’ tough cell structures are broken down with ultrasound — a gentle, modern method used in laboratory practice.
Ultrasound extraction
Step 3 / 5
Ethanol + hot water
Dual extraction with ethanol and hot water brings water- and alcohol-soluble compounds into the extract. Both mushrooms are processed in the same way.
Ultrasound + ethanol + hot water
Step 4 / 5
Lab testing
Every batch is tested in the lab. We document the results in a Certificate of Analysis (COA).
COA for every batch
Step 5 / 5
Bottling
Products are bottled and shipped from Kronach, discreetly packaged and with tracking.
Made in Bavaria
5,000
Years of tradition
Archaeologists found Tinder Fungus and Birch Polypore with the glacier mummy Ötzi. The use of both mushrooms is based on traditional knowledge passed down over generations. We combine this tradition with modern ultrasound extraction — without making medicinal claims.

02
Ultrasound
03
Ethanol + hot water

05
Bottling
Step 1 / 5
Wild harvesting
We hand-harvest Tinder Fungus and Birch Polypore in German forests. Only fruiting bodies are used, not mycelium.
Fruiting bodies only
Step 2 / 5
Ultrasound
The mushrooms’ tough cell structures are broken down with ultrasound — a gentle, modern method used in laboratory practice.
Ultrasound extraction
Step 3 / 5
Ethanol + hot water
Dual extraction with ethanol and hot water brings water- and alcohol-soluble compounds into the extract. Both mushrooms are processed in the same way.
Ultrasound + ethanol + hot water
Step 4 / 5
Lab testing
Every batch is tested in the lab. We document the results in a Certificate of Analysis (COA).
COA for every batch
Step 5 / 5
Bottling
Products are bottled and shipped from Kronach, discreetly packaged and with tracking.
Made in Bavaria
5,000
Years of tradition
Archaeologists found Tinder Fungus and Birch Polypore with the glacier mummy Ötzi. The use of both mushrooms is based on traditional knowledge passed down over generations. We combine this tradition with modern ultrasound extraction — without making medicinal claims.
