The lingzhi mushroom or reishi mushroom (traditional Chinese: 靈芝; pinyin: língzhī; Japanese: 霊芝; rōmaji: reishi; Vietnamese: linh chi; literally: "soul/spirit mushroom") is a species complex that encompasses several fungal species of the genus Ganoderma, most commonly the closely related species Ganoderma lucidum, Ganoderma tsugae, and Ganoderma lingzhi. G. lingzhi[1] enjoys special veneration in East Asia, where it has been used as a medicinal mushroom in traditional Chinese medicine for more than 2,000 years,[2] making it one of the oldest mushrooms known to have been used medicinally.

Description

Lingzhi is a polypore mushroom that is soft (when fresh), corky, and flat, with a conspicuous red-varnished, kidney-shaped cap and, depending on specimen age, white to dull brown pores underneath.[9] It lacks gills on its underside and releases its spores through fine pores, leading to its morphological classification as a polypore.

Preparation

Because of its bitter taste, lingzhi is traditionally prepared as a hot water extract product.[51] Thinly sliced or pulverized lingzhi (either fresh or dried) is added to a pot of boiling water, the water is then reduced to a simmer, and the pot is covered; the lingzhi is then simmered for two hours.[citation needed] The resulting liquid is fairly bitter in taste and dark, with the more active red lingzhi more bitter than the black. The process is sometimes repeated for additional concentration. Alternatively, it can be used as an ingredient in a formula decoction or used to make an extract (in liquid, capsule, or powder form). The more active red forms of lingzhi are far too bitter to be consumed in a soup.

Medical uses

A 2015 Cochrane database review found insufficient evidence to justify the use of G. lucidum as a first-line cancer treatment. It suggests that G. lucidum may have "benefit as an alternative adjunct to conventional treatment in consideration of its potential of enhancing tumour response and stimulating host immunity".[52] Existing studies do not support the use of G. lucidum for treatment of risk factors of cardiovascular disease in people with type 2 diabetes mellitus.

Habitat

Ganoderma lucidum, and its close relative Ganoderma tsugae, grow in the northern Eastern Hemlock forests. These two species of bracket fungus have a worldwide distribution in both tropical and temperate geographical regions, growing as a parasite or saprotroph on a wide variety of trees.[9] Similar species of Ganoderma have been found growing in the Amazon.[26] In nature, lingzhi grows at the base and stumps of deciduous trees, especially maple.[27] Only two or three out of 10,000 such aged trees will have lingzhi growth, and therefore its wild form is extremely rare. Today, lingzhi is effectively cultivated on hardwood logs or sawdust/woodchips.

History

The Chinese classics first used zhi during the Warring States period (475–221 BCE) and lingzhi during the Han Dynasty (206 BCE-220 CE).

The word zhi 芝 occurs approximately 100 times in classical texts.[29] Occurrences in early Chinese histories, such as the (91 BCE) Shiji "Records of the Grand Historian" and (82 CE) Hanshu "Book of Han", predominantly refer to the "Mushroom of Immortality; elixir of life". They record that fangshi "masters of esoterica; alchemists; magicians", supposedly followers of Zou Yan (305–240 BCE), claimed to know secret locations like Mount Penglai where the magic zhi mushroom grew. Some sinologists propose that the mythical zhi 芝 derived from Indian legends about soma that reached China around the 3rd century BCE.[30] Fangshi courtiers convinced Qin and Han emperors, most notably Qin Shi Huang (r. 221–210 BCE) and Emperor Wu of Han (r. 141–87 BCE), to dispatch large expeditions (e.g., Xu Fu in 219 BCE) seeking the zhi Plant of Immortality, but none produced tangible results. Zhi occurrences in other classical texts often refer to an edible fungus. The Liji "Record of Ritual" lists zhi "lichens" as a type of condiment.[31] The Chuci "Song of the South" metaphorically mentions, "The holy herb is weeded out".[32] The Huainanzi "Philosophers of Huainan" records a zizhi 紫芝 "Purple Mushroom" Aphorism, "The zhi fungus grows on mountains, but it cannot grow on barren boulders."

The word lingzhi 靈芝 was first recorded in a fu 賦 "rhapsody; prose-poem" by the Han dynasty polymath Zhang Heng (CE 78–139). His Xijing fu 西京賦 "Western Metropolis Rhapsody" description of Emperor Wu of Han's (104 BCE) Jianzhang Palace parallels lingzhi with shijun 石菌 "rock mushroom": "Raising huge breakers, lifting waves, That drenched the stone mushrooms on the high bank, And soaked the magic fungus on vermeil boughs."[34] The commentary by Xue Zong (d. 237) notes these fungi were eaten as drugs of immortality.

The (ca. 1st–2nd century CE) Shennong bencao jing "Divine Farmer's Classic of Pharmaceutics" classifies zhi into six color categories, each of which is believed to benefit the qi "Life Force" in a different part of the body: qingzhi 青芝 "Green Mushroom" for Liver, chizhi 赤芝 "Red Mushroom" for heart, huangzhi 黃芝 "Yellow Mushroom" for spleen, baizhi 白芝 "White Mushroom" for Lung, heizhi "Black Mushroom" 黑芝 for kidney, and zizhi 紫芝 "Purple Mushroom" for Essence. Commentators identify this red chizhi (or danzhi 丹芝 "cinnabar mushroom") as the lingzhi.

Chi Zhi (Ganoderma rubra) is bitter and balanced. It mainly treats binding in the chest, boosts the heart qi, supplements the center, sharpens the wits, and [causes people] not to forget [i.e., improves the memory]. Protracted taking may make the body light, prevent senility, and prolong life so as to make one an immortal. Its other name is Dan Zhi (Cinnabar Ganoderma). It grows in mountains and valleys.

While Chinese texts have recorded medicinal uses of lingzhi for more than 2,000 years, a few sources erroneously claim more than 4,000 years.[37] Modern scholarship accepts neither the historicity of Shennong "Divine Farmer" (legendary inventor of agriculture, traditionally r. 2737–2697 BCE) nor that he wrote the Shennong bencao jing.

The (ca. 320 CE) Baopuzi, written by the Jin Dynasty Daoist scholar Ge Hong, has the first classical discussion of Zhi.[38] Based upon no-longer extant texts, Ge distinguishes five categories of zhi, each with 120 varieties: Shizhi 石芝 "stone Zhi", Muzhi 木芝 "wood Zhi", Caozhi 草芝 "Plant Zhi", Rouzhi 肉芝 "flesh zhi", and junzhi 菌芝 "mushroom zhi. For example, the "mushroom zhi".

Tiny excresences. These grow deep in the mountains, at the base of large trees or beside springs. They may resemble buildings, palanquins and horses, dragon and tigers, human beings, or flying birds. They may be any of the five colors. They too number 120 for which there exist illustrations. All are to be sought and gathered while using Yu's Pace, and they are to be cut with a bone knife. When dried in the shade, powdered, and taken by the inch-square spoonful, they produce geniehood. Those of the intermediate class confer several thousands of years, and those of the lowest type a thousand years of life

Taxonomy and naming

Names for the lingzhi fungus have a two thousand-year history. The Chinese term lingzhi 靈芝 was first recorded during the Han dynasty (206 BC – 9 AD). Petter Adolf Karsten named the genus Ganoderma in 1881.

Botanical names

The fungus was given its first binomial name, Boletus lucidus, by English botanist William Curtis in 1781. The lingzhi's botanical names have Greek and Latin roots. The generic name Ganoderma derives from the Greek ganos γανος "brightness; sheen", hence "shining" and derma δερμα "skin".

The specific epithet lucidum is Latin for "shining". Tsugae is derived from the Japanese word for "hemlock" (tsuga 栂).

There are multiple species of lingzhi, scientifically known to be within the Ganoderma lucidum species complex and mycologists are researching the differences among species within this complex.

Chinese names

In the Chinese language, lingzhi is made up of the compounds ling 灵 "spirit, spiritual; soul; miraculous; sacred; divine; mysterious; efficacious; effective" (cf. Lingyan Temple) and zhi 芝 "(traditional) plant of longevity; fungus; seed; branch; mushroom; excrescence". Fabrizio Pregadio notes, "The term zhi, which has no equivalent in Western languages, refers to a variety of supermundane substances often described as plants, fungi, or "excresences"."[6] Zhi occurs in other Chinese plant names such as zhima 芝麻 "sesame" or "seed", and was anciently used a phonetic loan character for zhi 芷 "Angelica iris". Chinese differentiates Ganoderma species between chizhi 赤芝 "red mushroom" G. lucidum and zizhi 紫芝 "purple mushroom" G. japonicum.

Lingzhi has several synonyms. ruicao 瑞草 "auspicious plant" (with rui 瑞 "auspicious; felicitous omen" and the suffix cao "plant; herb") is the oldest; the (c. 3rd century BCE) Erya dictionary defines qiu 苬 (interpreted as a miscopy of jun 菌 "mushroom") as zhi 芝 "mushroom" and the commentary of Guo Pu (276–324) says, "The [zhi] flowers three times in one year. It is a [ruicao] felicitous plant."[7] Other Chinese names for Ganoderma include ruizhi 瑞芝 "auspicious mushroom", shenzhi 神芝 "divine mushroom" (with shen "spirit; god' supernatural; divine"), mulingzhi 木灵芝 (with "tree; wood"), xiancao 仙草 "immortality plant" (with xian "(Daoism) transcendent; immortal; wizard"), and lingzhicao 灵芝草 or zhicao 芝草 "mushroom plant".

Since both Chinese ling and zhi have multiple meanings, lingzhi has diverse English translations. Renditions include "[zhi] possessed of soul power",[8] "Herb of Spiritual Potency" or "Mushroom of Immortality",[9] "Numinous Mushroom",[10] "divine mushroom",[11] "divine fungus",[12] "Magic Fungus",[13] and "Marvelous Fungus".

Japanese names

Japanese language Reishi 霊芝 is a Sino-Japanese loan word from lingzhi. This modern Japanese kanji 霊 is the shinjitai "new character form" for the kyūjitai "old character form" 靈.

Reishi synonyms divide between Sino-Japanese borrowings and native Japanese coinages. Sinitic loanwords include literary terms such as zuisō 瑞草 (from ruicao) "auspicious plant" and sensō 仙草 (from xiaocao) "immortality plant". A common native Japanese name is mannentake 万年茸 "10,000 year mushroom". The Japanese writing system uses shi or shiba 芝 for "grass; lawn; turf" and take or kinoko 茸 for "mushroom" (e.g., shiitake). Other Japanese terms for reishi include kadodetake 門出茸 "departure mushroom", hijiridake 聖茸 "sage mushroom", and magoshakushi 孫杓子 "grandchild ladle".

English names

English lingzhi or ling chih (sometimes spelled "ling chi" from French EFEO Chinese transcription) is a Chinese loanword. The Oxford English Dictionary gives Chinese "líng divine + zhī fungus" as the origin of ling chih or lingzhi, and defines, "The fungus Ganoderma lucidum, believed in China to confer longevity and used as a symbol of this on Chinese ceramic ware."[15] The OED notes the earliest recorded usage of the Wade–Giles romanization ling chih in 1904,[16] and of the Pinyin lingzhi in 1980. In addition to the transliterated loanword, English names include "glossy ganoderma" and "shiny polyporus".
