How are we different?

Potent medicinal mushrooms have been grown in China for hundreds of years, and to this day the most nutrient-rich mushrooms come from Chinese cultivars. For over 2,000 years, the traditions of Chinese medicine have been applied to the cultivation of these mushrooms for a host of medicinal uses. Mushroom cultivation in China has furthermore been so refined that farmed variants are in no way inferior to their wild-grown counterparts. Our shiitaki are sourced directly from the globally-recognised mushroom-growing region of Gutian County in Fujian. Our farming partner is organically certified according to EU standards and places a high value on natural, traditional cultivation methods. The mushrooms are selectively harvested by hand between July and October for maximum nutritional value.

Mushrooms are composed of the fruiting body, which typically appears above ground, and the mycelium underneath. The most important nutrients are concentrated in the fruiting body. Products derived from the mycelium are frequently much cheaper because mycelia are cultivated faster, cheaper, and easier. Yet these products hardly contain any of the potent compounds of the mushroom. Our mushroom powders and extracts are exclusively made from the entire fruiting body of the mushroom (including the stem) and contain the full nutritional richness that the mushrooms have to offer.

The most important nutrients within the shiitake are the mushroom polysaccharides, especially beta-1,3-glucan and beta-1,6-glucan. Our mushroom extracts consolidate these compounds into a highly effective concentrate. The extract is produced according to a traditional method using only water and edible ethanol. The result is a pure and wholesome extract with absolutely no toxic extraction residues or chemical release agents (such as acetone, n-hexane, or methanol).

In contrast to extracts, which can lose some of their nutritional value during processing, powders contain the full spectrum of nutrients and enzymes for a particularly strong adaptogenic effect. To ensure that these nutrients are optimally bioavailable, our powder is gently ground according to the "shell-broken" method to a size of less than 0.1mm. This milling process breaks open the difficult-to-digest cells of the mushroom and makes their contents directly bioavailable.

By combining the mushroom powder and extract, this product offers the complete range of all the effective phytochemicals of shiitake including an especially high concentration of beta-glucans.

Shiitake (Lentinula edodes, Hua gu)

After the common mushroom (Agaricus bisporus), the shiitake is perhaps the most common and beloved edible mushroom in the world. Many Asian cuisines take advantage of shiitake's distinctly umami taste and firm texture, which is why shiitake is sometimes referred to as the king of mushrooms.

Shiitake flourishes on the decaying wood of deciduous trees in Japan, China, and Vietnam. It has been a staple ingredient in culinary dishes as well as medicine in East Asia for thousands of years. The use of shiitake as a strengthening elixir in Traditional Chinese Medicine has been documented by scriptures which are over 2,000 years old. In these texts, shiitake is referred to as the "elixir of life".

Shiitake contains all essential amino acids, which makes this mushroom particularly attractive for vegans and vegetarians. Moreover, it also contains many vitamins and minerals as well as beta-glucans including lentinan and the alkaloid eritadenine, both of which are used for the treatment of various illnesses.


Our medicinal mushrooms are sourced from the renowned mushroom-growing region of Gutian County (600-700m above sea level), in Fujian, China. The cultivation of mushrooms is an age-old tradition in the region, as is reflected by the unparalleled quality of these mushrooms. The fertile land, sophisticated substrates, as well as the climate, all contribute to a uniquely nutritious end product. Moreover, these pristine lands are protected by dense mountain forests, thus providing an ideal environment for the mushrooms to thrive. Our untreated mushrooms are certified organically grown according to EU standards. They are grown to full maturity and hand-picked at the peak of their vitality, between July and October.

The mushrooms retain their raw quality as a result of gentle drying at temperatures below 40°C. This process preserves the delicate enzymes and potent vital substances of the mushrooms. To ensure that these valuable nutrients are bioavailable, the dried mushrooms are then gently milled. Thanks to our use of the "shell-broken" method, the powder attains a fineness of less than 0.125mm, which ensures that the compounds within the cells as well as within the chitin skeleton of the mushroom are optimally available for absorption. The powder contains the full richness of enzymes, vitamins, minerals, and trace elements of the whole fruiting body of the mushroom.
