What Is Lion’s Mane?

Lion’s Mane is a distinctive white, cascading mushroom long used in East Asian cuisine and herb craft. In TCM, it’s considered food-like and gentle, traditionally used to support the Spleen/Stomach. Modern wellness has embraced Lion’s Mane in daily lattes, teas, smoothies, and convenient capsules.

Why Lion's Mane “Works”: TCM Perspective + Modern Research

TCM Perspective

• Harmonizes the Middle (Spleen/Stomach): Aids digestive comfort and post-meal ease.

• Clear, Even Energy: By supporting digestion, many people report steadier daytime focus.

Modern Research 

• Cognitive & Mood Support: Human and preclinical studies explore Lion’s Mane’s role in mental clarity and mood under everyday stress.

• Nerve Pathways: Ongoing research examines compounds (e.g., hericenones/erinacines) and nerve-growth-factor–related pathways.

• Gut–Brain Axis: Early evidence is investigating digestive comfort and microbiome interactions with perceived focus and calm.

Timing Tips

Most people prefer AM or midday for calm focus.

If you’re sensitive to being alert at night, avoid late-evening use.

As a side note:

In the Pacific Northwest, where we live, lion’s mane mushrooms—Hericium erinaceus and close relatives like H. abietis—are often spotted “just hanging” from trees after the fall rains, their shaggy white cascades looking like pom-poms or icicles. You’ll typically find them on dead or dying hardwoods such as alder, maple, and oak, and in this region sometimes on conifers (e.g., Douglas-fir or hemlock). They stand out against dark, mossy trunks in damp coastal forests and lower mountain slopes from late summer through winter. If you forage, only harvest when you’re 100% certain of identification, follow local regulations, and harvest ethically by leaving some behind to re-fruit.

Storage & Freshness

Keep dry, cool, and away from light.

Close containers tightly; use within the “best by” window.

Powders: consider a desiccant pack; avoid steamy kitchens.
