What it is
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.
How it works
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.
The protocol
1–2 g of dual-extracted reishi daily, ideally in the evening, with or without food.
Sourcing
Insist on fruiting-body extract (not mycelium grown on grain) and dual extraction so both classes of actives are present.
Honest caution
May potentiate anticoagulant medication. Discontinue two weeks before surgery and consult a clinician if on prescription blood thinners.
What it supports
- Immune modulation — Supports a measured immune response rather than overstimulating it.
- Deeper sleep — Eases the transition into rest without sedation.
- Heart and liver support — Traditionally used to support the cardiovascular and hepatic systems.
