Reishi: The Story Behind the “Mushroom of Immortality”
Few mushrooms have a history quite as extraordinary as Reishi.
Known as Lingzhi (灵芝) in China and commonly called Reishi in the West, this distinctive mushroom has appeared in Chinese art, herbal traditions and cultural symbolism for centuries.
Its reputation became so great that it acquired an almost mythical status, earning names such as the “Mushroom of Immortality.”
But where did that remarkable reputation come from?

What is Reishi?
Reishi belongs to the Ganoderma genus, a group of wood-growing fungi recognised by their distinctive fruiting bodies.
Perhaps the most familiar is the beautiful red, lacquered-looking form traditionally associated with Lingzhi.
Unlike familiar culinary mushrooms, Reishi has a characteristically woody texture and intensely bitter taste. Historically, it was therefore commonly prepared in water rather than eaten like an ordinary mushroom.
Today, Reishi can be found in teas, powders and concentrated extracts, making an ancient ingredient considerably easier to incorporate into modern life.
Why is Reishi called the “Mushroom of Immortality”?
Reishi's extraordinary nickname comes from its place within Chinese history and tradition.
Lingzhi became associated with ideas of longevity, good fortune and spiritual wellbeing, and representations of the mushroom can be found throughout traditional Chinese art.
It appeared in paintings, carvings, furniture, textiles and objects associated with imperial China. Its distinctive shape became sufficiently recognisable that the mushroom itself developed into a symbol of longevity.
References to Lingzhi also appear within historical Chinese herbal literature, helping establish a reputation that would endure for generations.
The “Mushroom of Immortality” is therefore best understood as a cultural and historical description, rather than a literal claim about what consuming Reishi can do.
And we think the real history is fascinating enough without turning the legend into a modern health promise.
Reishi and traditional Chinese herbalism
Reishi has an important place within Chinese herbal tradition.
Historical texts discuss Lingzhi within the traditional frameworks used to understand herbs and the body at the time.
You'll sometimes encounter concepts such as Qi, Jing and Shen when reading about Reishi and other traditional Chinese herbs.
These concepts belong to Traditional Chinese Medicine and shouldn't be interpreted as direct equivalents of modern anatomical or medical terminology.
Nevertheless, they provide an interesting window into how Reishi was understood historically — particularly its association with longevity, balance and spiritual practices.
Reishi in Chinese art and symbolism
Reishi's cultural history extends well beyond herbalism.
The mushroom's unusual form became a recurring motif in Chinese art and decorative objects, particularly in imagery connected with longevity and good fortune.
It could appear alongside other traditional symbols of longevity such as cranes, deer and pine trees.
This is one of the things that makes Reishi so unusual.
Very few mushrooms have crossed the boundary between food, traditional herbal practice, folklore, spirituality and art quite so successfully.
What is Duanwood Reishi?
The way Reishi is cultivated is another fascinating part of its story.
Duanwood cultivation is a traditional method in which Reishi is grown using sections of natural hardwood rather than simply being produced on a grain-based substrate.
The wood provides the mushroom with an environment closer to the material on which Ganoderma species naturally grow.
Duanwood cultivation takes considerably more time and space than many modern mushroom-production methods, but it remains particularly associated with traditionally cultivated Reishi.
It's the method we continue to favour for our own Reishi.
Fruiting body vs mycelium
Another useful distinction when exploring mushroom products is the difference between the fruiting body and mycelium.
The fruiting body is the recognisable mushroom that develops above its growing material. Mycelium is the network of fungal threads from which that fruiting body develops.
Some modern mushroom products are produced from mycelium grown on grain, while others use harvested mushroom fruiting bodies.
Our Reishi extract is made from 100% Duanwood-grown fruiting bodies.
For us, knowing what part of the mushroom you're actually buying is an important part of understanding any mushroom extract.
What does Reishi contain?
Reishi is a remarkably complex fungus containing numerous naturally occurring compounds.
Two groups frequently discussed in modern Reishi research are beta-glucans and triterpenes, including compounds known as ganoderic acids.
These constituents have contributed to considerable scientific interest in Ganoderma species.
Research into Reishi continues, but it's important to distinguish scientific investigation from the much stronger health claims that are sometimes made online.
An interesting research paper isn't automatically proof that consuming a Reishi product will produce the same result in people.
From traditional decoctions to modern extracts
Traditionally, Reishi's tough, woody fruiting body meant that it was often prepared by simmering it in water.
A modern extract provides a considerably more convenient alternative.
At Hybrid Herbs, our Reishi starts with Duanwood-grown fruiting bodies before being concentrated into a 10:1 extract powder.
That means we're able to offer Reishi in a form that's easy to mix into hot water, plant-based drinks, smoothies or other recipes without asking you to spend hours simmering pieces of mushroom.
The method may have changed, but the mushroom behind it has an extraordinary history stretching back generations.

We've worked with mushroom extracts at Hybrid Herbs since 2010, and Reishi remains one of the mushrooms that best represents why we became fascinated with them in the first place.
Its unusual biology, traditional Duanwood cultivation, distinctive bitterness and extraordinary place within Chinese culture make Reishi much more interesting than a list of exaggerated health claims.
