What is it

Armillaria mellea, the honey mushroom, is an edible and medicinal fungus widely distributed in temperate forests. The fruiting body and mycelium appear in some specialty mushroom supplements.

How it works

Like other medicinal mushrooms, Armillaria mellea contains beta-glucans and other polysaccharides that may modulate immune responses. Traditional Chinese medicine uses it (mi huan jun) for sleep, headache, and neurological complaints. Human clinical evidence is limited. Most claims are based on small Chinese studies and extrapolation from related medicinal mushrooms.

Dosage

There is no established daily intake recommendation. Mushroom extract supplements typically range from 500 mg to 2 g per day. Honey mushrooms can also be eaten as a food.

When and how to take it

Mushroom extracts are typically taken with meals. Traditional uses for sleep support suggest evening dosing.
