Reishi

Reishi is a varnished, woody-fruited polypore that has been used in Chinese, Japanese, and Korean wellness traditions for over two thousand years — referred to in classical Chinese medicine as "the mushroom of spiritual potency." It is one of the most distinctive medicinal mushrooms because its bioactivity is dominated by triterpene chemistry rather than purely polysaccharide chemistry.

MYKO uses a 12:1 hot-water-and-ethanol dual extract — twelve units of fruiting body concentrated into one unit of finished extract — to capture both the triterpene and beta-glucan fractions.

MYKO uses Reishi to support a calm, parasympathetic, downshifted nervous system. It is the counterweight to Cordyceps in CORTEX, the immune-and-restoration partner in EMBODY, and the calming foundation in EUPHORIA. Reishi is the tone control of the MYKO line — the ingredient that lets active formulas finish smoothly rather than feeling spikey.

Customers most often describe Reishi as a "system softener" — a quieting of nervous-system static, smoother evenings, and an easier transition into sleep. The effect is cumulative; it builds over 2–4 weeks of daily use.

Within MYKO formulas, Reishi is the parasympathetic counterweight: it pairs with Cordyceps to make CORTEX feel like calm vigilance rather than caffeine focus, and grounds the openness of EUPHORIA so the experience finishes with stability.

What is reasonably supported: HPA-axis and parasympathetic modulation mechanisms; immune-marker shifts in adjunct-therapy populations; long traditional use as a calm and recovery substance.

What is still emerging: clean RCTs for sleep, anxiety, and cortisol in healthy adults; standardized triterpene-content dosing.

What should not be claimed strongly: "treats anxiety," "cures insomnia," "prevents cancer," "lowers cortisol by X%."

Where more human research is needed: dose-response for ganoderic acids; standardization of triterpene fractions across suppliers; sleep-architecture outcomes in non-clinical populations.
