Reishi

Reishi (Ganoderma lucidum) is the "mushroom of immortality" of East Asian tradition, valued today for calm, sleep and immune support. Our collection covers three formats: daily capsules, whole dried fruiting body for decoctions, and a concentrated dual-extract tincture. Because reishi's prized triterpenes are only released by hot-water and alcohol extraction, format and processing genuinely matter here — our label-reading guide shows what to look for.

Reishi is an adaptogen: it is taken to help the body handle stress, to support restful sleep, and for its broad wellness properties. Unlike lion's mane or cordyceps, it is usually taken in the evening. If sleep and winding down are your goal, it also anchors our calm routines alongside gentler botanicals.

The tincture is the most potent per drop and simplest to dose; capsules keep a daily habit effortless; the dried fruiting body is traditional and economical if you brew your own reishi tea. Get started with our dosage guide and timing guide, and review side effects and interactions if you take medication.

Choosing between the three formats. Reishi holds two compound groups with opposing solubility, and this is the single fact that makes format matter. The triterpenes — the bitter, resinous ganoderic acids — are alcohol-soluble. The beta-glucans and polysaccharides are water-soluble and need prolonged heat to release from the chitin cell walls. A traditional decoction extracts the second group well and the first poorly; a plain alcohol tincture does the reverse. Only a dual extraction captures both, which is why our tincture is double-extracted rather than simply macerated in spirit.

A practical quality test: genuine reishi should taste distinctly bitter. That bitterness is the triterpene fraction. A reishi product that tastes of nothing is usually either a water-only extract or a mycelium-on-grain powder — mycelium grown on a starch substrate that cannot be separated out and is milled into the finished product, leaving something largely composed of grain. Every reishi item in this collection is 100% fruiting body, batch-tested for beta-glucan and triterpene content.

What to expect, and when. Reishi is an adaptogen, not a stimulant or a sedative in the pharmaceutical sense, and it does not produce a same-day effect the way caffeine does. Traditional and modern use alike assume daily intake over weeks — consistency matters far more than dose size, and a modest amount taken every day serves better than an occasional large one. Most people find it settling rather than energising, which is why evening use is the common default.

Before you start. Reishi may increase bleeding risk and can interact with anticoagulant and antiplatelet medication — discontinue at least two weeks before scheduled surgery. As an immune-modulating mushroom it may interact with immunosuppressants, and anyone with an autoimmune condition should speak with their doctor first. It may also lower blood pressure and blood sugar. Not for use during pregnancy or breastfeeding.
