What are reishi mushrooms?


Ganoderma Lucidum is a rare mushroom rich in 「Beta glucan」

Ganoderma  Lucidum belongs to Basidiomycetes Polyporaceae species of mushrooms. The history of studying Ganoderma  Lucidum is long.  Approximately  2200 years ago, the efficacy of  Ganoderma Lucidum is documented in  China's oldest medical book " Divine Husbandman's Classic on Pharmacology ".  It is also recorded in Japan’s “Chronicles of Japan” as “tufted herb”.

Under ordinary circumstances, it grows rarely on the decayed tree of Prunus mume,  oaks.  Nowadays, artificial cultivation has become possible.  We have also set up our own R & D cultivation techniques and then carry on the production. We are currently producing two types of Ganoderma Lucidum: the "red Ganoderma  Lucidum" and the rare " Deer Horn Shaped Ganoderma Lucidum ".

Depending on the amount of light, temperature, humidity, and other factors, the Ganoderma Lucidum shape changes considerably, and sometimes lose its umbrella shape and take the shape of Deer Horns. Among the  Ganoderma Lucidum Mushrooms, the Deer Horns Shaped Ganoderma Lucidum contains a higher value of Beta glucan.



Once reserved for royalty to extend life and improve health, this polypore mushroom is strikingly beautiful. Deep reddish brown and saucer-shaped, often emerging from a branch-like stem, its smooth upper surface looks lacquered when wet. Because of this glossy appearance, Western mycologists called them "varnished conks" for many years (conks are mushrooms that have pores instead of gills on their undersides, such as maitake and turkey tails).


The reasons it is trusted

While reishi mushrooms have historically been prepared as teas or infusions, other modern preparations include capsules, tinctures, and fractionated extracts of mushrooms, mycelium, and spores. Reishi is also added to chocolate bars, candies, energy drinks, and even coffee blends! Because of its rich history and long tradition of medicinal use, Ganoderma lucidum (in the strictest sense) is now one of the few mushroom species whose DNA has been fully sequenced (16,113 genes). Others are button mushrooms (Agaricus bisporus) with 10,438 genes and oyster mushrooms (Pleurotus ostreatus) with 12,330 genes (Joint Genome Institute). Reishi is remarkable for its diversity of genes coding for cytochrome P450 enzymes. These enzymes not only afford this species a broad arsenal for producing secondary metabolites for digesting nutrients but may also confer benefits to human health such as enhancing the degradation of toxins and free radicals and increasing the liver's metabolic efficiency. The variety of these enzymes, among more than 400 active constituents that have been found, indicates that mushrooms such as reishi are like miniature pharmaceutical factories that can produce hundreds of medicinally-interactive compounds. Through trial-and-error and observable outcomes, our ancestors narrowed the field of edible mushroom candidates to just a few with remarkable, health-supporting properties. Today, reishi stands out as one the most valuable of all polypore mushrooms in nature for the benefit of our health. Many naturopaths and doctors prefer organically-grown reishi ( and we are the only grower certified JAS Organic in Japan)from pristine environments because they are purer.

How should I choose the right reishi product?

Reishi products are available in tablet, capsule, or granular form. A good Reishi product should be in powder form or in capsule form . The less treatment they receive the better the product is.

Quality of Reishi products differs greatly depending on the manufacturer. Factors such as the method of cultivation, the quality of the fungi strain, the growing conditions, and the processing method used to process the Reishi mushroom all play an important role in determining the potency of a Reishi product.

Modern wood log technique to cultivated reishi at a bigger scale was developed in Japan in the 1970s, products from Japan tend to use Safe and high-grade Reishi.

Before deciding on which product to use, also make sure that it is properly and clearly labelled with the ingredients, extract ratio, manufacturer or importer address, and product origin. Any authentic, high-quality, and safe health supplement will contain this information.


Another important factor to consider is the level of active ingredient contents of the fruiting body such as polysaccharides  (ours is around 60%) and triterpenoids.


What are the different types of cultivation for red Reishi?

The most common method of cultivation are the wood pulp (sawdust and bottle), wooden box, and natural wood log cultivation.

Wood pulp cultivation consists of placing wood pulp or sawdust in a glass bottle with Reishi fungi added. After 3 months, this usually will yield small mushrooms of relatively poor quality.

Wood box cultivation involves grafting the fungi into a wooden log which is then placed in a wooden box. Reishi of medium-size and moderate quality are generally produced through this method after 6 months.

The natural wood log method, developed first by the Japanese, is the most complex form of cultivation and produces large red Reishi with superior quality.


The process involves first culturing high-quality Reishi fungi strain in test tubes for about 85 days. Germinating fungi are then placed into drilled holes of selected high-grade logs between 26 to 30 years old. The logs are then placed in a greenhouse and buried under nutrient-rich soil for 5 months. During this growing period, the Reishi fungi absorb almost all of the nutrients from the soil.


Growing conditions require continual monitoring to ensure a high-quality Reishi harvest.

Why Red Reishi? What is the difference with the other reishi?

Among all the reishi that are known to have health benefits black and red Reishi have shown the most potency in dealing with diseases and were proven to be the ones with the most considerable health-enhancing effects.

Black Reishi (Ganoderma Sinensis), is fairly common and can be found in most Chinese herbal shops (they have a lower content in active ingredient and are less potent).
