Medicinal mushrooms is a commonly used term for mushrooms with a history of use in traditional systems of medicine and that have been studied for their biologically active compounds.

Mushrooms such as Reishi, Lion’s Mane, Turkey Tail, and Cordyceps are now the subject of extensive research into their distinct constituents and potential effects on human health.

Different mushrooms have different compositions and properties. Reishi, Lion’s Mane, Turkey Tail, and Cordyceps each contain distinct compounds that have been studied in areas including antioxidant activity, immune function, cognitive health, energy metabolism, and overall wellbeing.

At Language, we formulate with each mushroom according to its individual character, composition, and intended use.

A mushroom extract is a concentrated preparation made by extracting compounds from mushrooms. Different extraction methods can make different classes of mushroom compounds more available, depending on the species and the compounds being targeted.

Mushroom extracts can be prepared in liquid, powder, capsule, and other forms. Language creates concentrated liquid mushroom extracts designed to be simple to incorporate into a daily ritual.

Follow the serving instructions provided for your specific Language extract. Our liquid extracts can be taken directly or added to water, tea, coffee, smoothies, or another beverage.

We designed them to be easy to incorporate into the rituals you already have.

Fresh mushrooms and mushroom extracts serve different purposes and can both be valuable parts of a mushroom-rich lifestyle.

Eating fresh mushrooms provides the benefits of the whole food, including fiber, nutrients, and naturally occurring mushroom compounds. 

Extracts are concentrated preparations designed to make specific mushroom compounds more accessible and convenient to consume in a consistent amount. They are not a replacement for eating mushrooms—they are another way to work with them.

Yes. Culinary mushrooms are nutrient-dense foods that provide fiber, protein, vitamins, minerals, and naturally occurring bioactive compounds. Different mushroom species have different nutritional profiles, making variety especially interesting.

Mushrooms such as Shiitake, Oyster, Maitake, and Lion’s Mane can be incorporated into meals in countless ways—from sautés and soups to broths, grains, sauces, and more.

Cooked mushrooms are an excellent addition to a balanced diet. 

The best mushroom ritual doesn't have to be complicated. Sometimes it's simply a skillet, a little heat, and whatever you're already making for dinner.

You don't necessarily have to choose.

Fresh mushrooms are whole foods that can contribute nutrients, fiber, and mushroom compounds to your diet. Mushroom extracts offer a concentrated and convenient way to incorporate specific mushrooms into a daily routine.

We think of them as different expressions of the same vocabulary: eat the mushroom, extract the mushroom, get to know the mushroom.

Reishi (Ganoderma lingzhi) is a functional mushroom rich in naturally occurring polysaccharides and triterpenes. It has been extensively studied for antioxidant activity, immune modulation, inflammatory pathways, and its relationship to stress and overall wellbeing.

Reishi is often associated with grounding and restorative rituals and can be used throughout the day depending on the formula.

Lion’s Mane (Hericium erinaceus) contains distinctive compounds that have been studied for their relationship to the nervous system, cognitive function, antioxidant activity, and neurotrophic pathways.

It is particularly well suited to daily rituals centered around focus, clarity, and long-term brain health.

Turkey Tail (Trametes versicolor) is a functional mushroom known for its polysaccharides, including beta-glucan-rich compounds that have been extensively studied for their relationship to immune function and gut health.

Its complex chemistry makes it one of the most widely researched medicinal mushrooms.

Cordyceps is a group of fungi containing compounds that have been studied in relation to energy metabolism, exercise performance, oxygen utilization, and physical endurance.

Cordyceps is particularly well suited to daytime rituals centered around energy, movement, and vitality.

Mushrooms contain naturally occurring polysaccharides, triterpenes, antioxidants, and other bioactive compounds that have been studied for their potential role in skin health.

We formulate mushrooms alongside botanical oils, herbs, and flowers to create skincare that nourishes and conditions the skin while bringing mushrooms into an everyday ritual.

Reishi contains polysaccharides, triterpenes, and antioxidant compounds that have been studied in relation to oxidative stress, inflammation, hydration, pigmentation, and visible signs of photoaging.
