This fungus, celebrated for centuries in Asian cultures for its medicinal properties, is now recognized worldwide for its potential health benefits.

This article explores its nutritional content, various forms, and ways to enjoy it while also considering potential side effects.

What Is Reishi Mushroom?

Reishi mushroom, scientifically identified as Ganoderma lucidum, is a type of polypore fungus revered in East Asian traditional medicine for over 2,000 years. This basidiomycete mushroom, commonly referred to as “Lingzhi” in China and “Mannentake” in Japan, has been extensively chronicled in classical pharmacopeias such as the Shen Nong Ben Cao Jing for its tonic effects and longevity-enhancing properties.

Reishi is classified as an adaptogen, meaning it helps the body resist various stressors, both physical and psychological. It contains bioactive constituents—notably triterpenoids, β-glucans, and ganoderic acids—that are known to modulate immune response, exhibit anti-tumor activity, and improve liver function. A 2021 review in Journal of Ethnopharmacology confirmed that Ganoderma lucidum enhances natural killer (NK) cell activity, supporting its traditional use in immune modulation.

“Reishi represents a bridge between traditional herbal wisdom and modern immunological science,” states Dr. Hirokazu Kawagishi, a leading researcher in myco-pharmacology at Shizuoka University.

Modern pharmacognosy measures its therapeutic quality based on polysaccharide and triterpenoid content, and formulations range from hot water extracts to ethanol-based tinctures, each affecting compound bioavailability differently.

As a functional food and nutraceutical, Reishi mushroom plays a critical role in preventative health regimens, but users should monitor for possible contraindications with immunosuppressants or anticoagulant medications.

What Are The Different Names Of Reishi Mushroom?

Reishi mushroom, scientifically known as Ganoderma lucidum, is referred to by various names across cultures and scientific classifications, reflecting its widespread historical use and cultural reverence.

In Traditional Chinese Medicine (TCM), it is called “Lingzhi” (灵芝), which translates to “spirit plant” or “divine fungus,” symbolizing immortality and spiritual potency. In Japan, it is known as “Mannentake” (万年茸), meaning “10,000-year mushroom,” and in Korea, it is called “Yeongji” (영지).

Taxonomically, Reishi belongs to the Ganodermataceae family, and among its known variants are Ganoderma tsugae (native to North America), Ganoderma applanatum, and Ganoderma sinense.

Each species exhibits varying concentrations of pharmacologically active compounds, such as ganoderic acids and β-glucans, which influence their therapeutic efficacy.

A review published in Mycological Progress (2022) highlights that more than 80 Ganoderma species have been recorded worldwide, yet G. lucidum remains the most studied due to its rich triterpenoid profile and immunological activity. “Lingzhi is not just a mushroom—it represents a pharmaco-cultural icon that bridges mycology and human longevity,” asserts Dr. Zhang Wei, a mycologist at Beijing University of Chinese Medicine.
