Ganoderma, commonly known as Reishi mushrooms, is a genus of polypore fungi in the family Ganodermataceae. They are characterised by their large, woody brackets, also called conks, and their fan-like or hoof-like appearance. Ganoderma species are found all over the world, particularly in tropical regions, and are used in traditional Asian medicine. They are believed to have various health benefits, including boosting the immune system, reducing fatigue, and improving cholesterol and blood sugar. However, there is limited scientific evidence to support these claims, and consuming the powder for longer than a month may be unsafe.

Ganoderma mushrooms are used in traditional Asian medicine
Ganoderma mushrooms, also known as reishi or lingzhi, have been used in traditional Asian medicine for centuries. The genus Ganoderma was established in 1881 by mycologist Karsten and includes about 80 species, many of which are found in tropical regions. Ganoderma mushrooms are characterised by their large, woody brackets, also called "conks", and their fan-like or hoof-like shape. They are known for their bitter taste and have been used for promoting health and longevity in China, Japan, and other Asian countries.
In traditional Chinese medicine, the lingzhi mushroom is revered as the "mushroom of immortality". It is mentioned in the 1st century CE chronicles of Shiji by Sima Qian and in the poetry of Ban Gu, where it is associated with mystical teachings and the opportunity to see or become a spirit. The Taoist treatise of Baopuzi from Ge Hong also mentions the use of lingzhi for immortality. In ancient China, it was believed to have the power to heal the body and calm the mind, and it is still widely consumed today.
Ganoderma mushrooms are known for their high genetic diversity, and different species are favoured in different geographical regions. For example, black Ganoderma lucidum is popular in South China, while red Ganoderma lucidum is preferred in Japan. The red lingzhi mushroom, or Ganoderma sichuanense, is the most widely found species in Chinese herb shops today. It is also the most likely species to be referenced in ancient texts, according to molecular work by Dai et al. (2017).
Ganoderma mushrooms have been studied for their potential health benefits, including their effects on the immune system, cholesterol, blood sugar, and antioxidants. They contain diverse phytochemicals, such as triterpenoids and polysaccharides, and enzymes that allow them to break down wood components. However, there is no high-quality evidence that Ganoderma or its phytochemicals are medicinally effective in humans. Ganoderma mushrooms are not edible, and consuming the powder for longer than a month may be unsafe.

They have a long history of promoting health and longevity in China
Ganoderma mushrooms, also known as reishi or lingzhi mushrooms, have been used for centuries in traditional Chinese medicine. The ancient Chinese believed that the lingzhi mushroom was the "mushroom of immortality", owing to its perceived ability to heal the body and calm the mind.
In ancient Taoist texts, the mushroom is referred to as the "spirit mushroom", and it is said that consuming it allowed followers to see spirits or become spirits themselves. The mushroom was also believed to positively affect one's "life energy" or Qi, and to bring about longevity.
The lingzhi mushroom is native to East Asia, where it grows as a parasite or saprotroph on a variety of trees, especially maples. It is characterised by a reddish-brown, varnished, kidney-shaped cap with bands and a peripherally inserted stem, giving it a distinct fan-like appearance.
Today, lingzhi mushrooms are cultivated on hardwood logs, sawdust, or woodchips, and are used in the clinical, pharmaceutical, and nutritional industries for the treatment of various diseases, including migraine, hypertension, asthma, hepatitis, cancer, and cardiovascular problems. Ganoderma mushrooms contain diverse phytochemicals with undefined properties in vivo, such as triterpenoids and polysaccharides. While there is no high-quality evidence of their medicinal effectiveness, ongoing research suggests that they may help reduce fatigue and improve cholesterol, blood sugar, and antioxidants.

They are characterised by large, woody brackets called conks
Ganoderma mushrooms, also known as reishi or lingzhi mushrooms, are characterised by large, woody brackets called conks. These mushrooms are polypore fungi, meaning they have pores or tubes through which they release spores, rather than gills. The conks of Ganoderma mushrooms are perennial, meaning they persist for more than one year, and they are lignicolous, meaning they grow on wood. The fruit bodies of these mushrooms typically grow in a fan-like or hoof-like form on the trunks of living or dead trees. They have a double-walled basidiospore, which is a unique feature that differentiates them from other polypores.
The genus Ganoderma was established in 1881 by Karsten and initially included only one species, G. lucidum. Today, the genus includes about 80 species, many of which are found in tropical regions. Ganoderma mushrooms can be identified by their shape, colour, host specificity, and geographical origin. They are wood-decay fungi with a cosmopolitan distribution and are often found in subtropical regions of the Orient.
The appearance of Ganoderma mushrooms can vary depending on the species and growing conditions. For example, the Ganoderma lingzhi, also known as the reishi or lingzhi mushroom, has a reddish-brown, varnished, kidney-shaped cap with bands and a peripherally inserted stem, giving it a distinct fan-like appearance. When fresh, it is soft, cork-like, and flat. On the other hand, Ganoderma tsugae, which grows on conifers, has a shiny cap surface similar to G. lucidum, while Ganoderma sinense, also known as black reishi, has a dull cap surface.
Ganoderma mushrooms have a long history of use in traditional Asian medicine, particularly in China, Japan, and other Asian countries. They are believed to have various health benefits, including boosting the immune system, reducing fatigue, improving cholesterol and blood sugar levels, and acting as antioxidants. However, it is important to note that there is limited scientific evidence to support these claimed benefits, and consuming Ganoderma products for extended periods may be unsafe.

They are used to treat diseases like cancer, Alzheimer's, and hypertension
Ganoderma lucidum, also known as the Reishi mushroom, is a type of mushroom that grows on plum trees in Asia. It is a large, dark mushroom with a glossy exterior and a woody texture. The Latin word "lucidus" means "shiny" or "brilliant", referring to the varnished appearance of the mushroom's surface. Ganoderma mushrooms have been used in traditional Chinese medicine for over 2000 years and are believed to promote health and longevity. They are also widely recommended by Asian physicians and naturopaths for their positive effects on the immune system.
Ganoderma mushrooms are used to treat a variety of diseases, including cancer, Alzheimer's, and hypertension. In cancer treatment, Ganoderma lucidum extract is a popular complementary and alternative medicine used by traditional Chinese medicine practitioners. Laboratory research and preclinical trials have shown that the mushroom carries promising anticancer and immunomodulatory properties, with antitumor activity. It is often recommended as an immune system support supplement for cancer patients, helping to combat the side effects of radio/chemotherapy.
In the context of Alzheimer's disease, Ganoderma lucidum has therapeutic potential due to its efficacy against multiple pathogenesis of Alzheimer's. Studies have shown that it can ameliorate spatial learning and memory deficits in rats with hypercholesterolemia and Alzheimer's. Further clinical trials are needed to unlock the complete potential of Ganoderma lucidum as a treatment for Alzheimer's disease.
Additionally, Ganoderma lucidum has been studied for its potential in treating hypertension and improving cardiovascular health. Clinical trials indicate that it can lower blood pressure, cholesterol, and blood glucose levels in humans. Ganoderma lucidum is becoming increasingly popular in Western countries as a complementary medicine for cardiovascular health. However, it is important to note that evidence from some randomised controlled trials does not support its use in treating cardiovascular risk factors in people with type 2 diabetes mellitus.

Ganoderma mushrooms, also known as lingzhi or reishi, are a genus of polypore fungi that includes about 80 species, many from tropical regions. They are commonly referred to as "shelf mushrooms" or "bracket fungi" and are characterised by their large, woody brackets, also called "conks". Ganoderma mushrooms have a long history of use in traditional Asian medicine, particularly in China, Japan, and other Asian countries, where they are believed to promote health and longevity.
The use of Ganoderma mushrooms as a medicinal herb can be traced back to ancient times, with references to the mushroom appearing in the 1st century CE in the chronicles of Shiji by Sima Qian and the poetry of Ban Gu. In Taoist teachings, the use of woody mushrooms, or "spirits mushrooms", was believed to give followers the opportunity to see spirits or become spirits themselves by receiving the magical energy of the immortals. The mushroom was also mentioned in the philosophical work Huainanzi, where it was said to be a personification of nobility, and shamans would brew it into a psychedelic drink.
In traditional Chinese medicine, Ganoderma mushrooms are believed to have healing powers and the ability to calm the mind. They have been studied for their potential bioactive properties, including antibacterial, antioxidant, and antitumor effects. The beneficial health properties of Ganoderma species are attributed to a wide variety of bioactive components, such as polysaccharides, triterpenes, sterols, lectins, and other proteins.
The Ganoderma mushroom is also known as the "mushroom of immortality" due to its perceived ability to positively affect life energy or Qi. According to ancient texts, consuming the mushroom over a long period can lengthen life and preserve the agility of the body. While there is no conclusive scientific evidence to support these claims, modern research suggests that Ganoderma mushrooms may have various health benefits, including boosting the immune system, reducing fatigue, improving cholesterol and blood sugar levels, and acting as an antioxidant.
Today, Ganoderma mushrooms are widely consumed and marketed internationally in various forms, including capsules, tablets, and extracts. However, it is important to note that consuming Ganoderma mushrooms in powdered form for extended periods may be unsafe, and there is limited scientific evidence to support all of the claimed health benefits.
