Functional Mushrooms
Nature’s adaptogens for focus, immunity and resilience.
Functional mushrooms have been used for centuries in traditional medicine systems across Asia and Europe. Today, a growing body of research is exploring how compounds found in mushrooms like Lion’s Mane, Reishi, Cordyceps, Turkey Tail and Chaga may support cognition, immune function, energy and stress resilience.
At Green Gorilla we treat functional mushrooms as part of a wider wellness stack — not a cure, but a tool. This guide explains what each mushroom is traditionally used for, what current research suggests, and how different forms (powders, extracts, tinctures, teas) compare so you can make informed choices.
Educational content only — not medical advice. We share traditional use and emerging research; consult a qualified practitioner before using herbs or supplements, especially if you take medication or are pregnant.
Plant & Knowledge Profiles
Lion’s Mane
Hericium erinaceus
A white, cascading mushroom studied for its potential to support nerve health and cognition.
Traditional use
Used in traditional Chinese and Japanese practice to support the spleen, gut and “calming of the spirit.”
What research suggests
Pre-clinical research highlights hericenones and erinacines, compounds associated with nerve growth factor (NGF) activity. Early human trials suggest possible benefits for mild cognitive impairment, though larger studies are needed.
Reishi
Ganoderma lucidum
Known as the “mushroom of immortality” in traditional East Asian medicine.
Traditional use
Traditionally used to calm the mind, support sleep and promote longevity and immune balance.
What research suggests
Contains triterpenes and beta-glucans. Research is ongoing into its potential immunomodulatory and adaptogenic effects; evidence in humans remains preliminary.
Cordyceps
Cordyceps sinensis / militaris
A fungus traditionally associated with stamina and respiratory support.
Traditional use
Used in Tibetan and Chinese medicine to support energy, lung function and athletic endurance.
What research suggests
Cordycepin is being studied for potential effects on oxygen utilisation and fatigue. Some small studies report exercise-performance benefits, but findings are not yet conclusive.
Turkey Tail
Trametes versicolor
A colourful bracket mushroom rich in polysaccharides.
Traditional use
Traditionally brewed as a tea to support immune resilience.
What research suggests
Polysaccharopeptides (PSK/PSP) have been studied extensively in Asia, often as an adjunct in oncology care. We present this as emerging research, not a treatment claim.
Chaga
Inonotus obliquus
A slow-growing conk that grows on birch trees in cold climates.
Traditional use
Used for centuries in Siberian and Russian folk medicine as a general tonic and antioxidant.
What research suggests
Extremely high in melanin and phenolic compounds; studied for antioxidant activity. Always brewed/extracted — raw chaga is not digestible on its own.

Are functional mushrooms psychedelic?+
No. The functional mushrooms listed here (Lion’s Mane, Reishi, Cordyceps, Turkey Tail, Chaga) do not contain psilocybin and are not psychoactive.
Extract vs powder — what’s the difference?+
Powders are whole-ground mushroom material. Extracts (often dual-extracted with water and alcohol) concentrate bioactive compounds and are typically easier for the body to absorb, especially for tough, chitinous mushrooms like Reishi and Chaga.
How long until I notice anything?+
Functional mushrooms are gentle adaptogens. Consistent daily use over weeks is generally recommended rather than expecting immediate effects.
Can I take mushrooms with medication?+
Speak to a qualified healthcare practitioner first. Some mushrooms may interact with immune-modulating or blood-thinning medication.
