Reishi grows on hardwood stumps across East Asia and has been documented in Chinese and Japanese pharmacopoeia for more than two thousand years, where it is sometimes called the mushroom of immortality.
Its medicinal value is split between two chemical classes: water-soluble beta-glucans that engage the immune system, and alcohol-soluble triterpenes responsible for the bitter taste and the calming, cardiotonic reputation.
How it works in the body
Beta-glucans interact with pattern-recognition receptors on immune cells, helping the body respond more measuredly. Triterpenes appear to influence GABA signalling, which is part of why reishi is associated with quieter sleep.

Honest answers
- Will reishi make me drowsy?
- It is not sedating. It supports the architecture of sleep rather than knocking you out.
- Why dual-extracted?
- Beta-glucans need water; triterpenes need alcohol. A dual extraction captures both.
