What it is known for
Triterpenes, ganoderic acids, and beta-glucans
Reishi's most-studied compounds are its triterpenes, the family that includes ganoderic acids, along with its beta-glucans and other polysaccharides. In Japanese and Chinese tradition it carries old names like the mushroom of longevity. That is tradition, named as tradition, and this is general background about the Reishi mushroom, not a claim about what our extract does for you.
How to take it
Three easy ways
Shake well, then hold 1ml under your tongue for 30 to 60 seconds.
Or stir 1ml into a glass of cold water or any drink you like.
Or work it into a light meal. Fruit especially. That works, though I'd point you to a drink first.
The flavor surprises people. It's sweet and silky, an apple flavor with a mild tartness, no more sour than a piece of fruit you'd actually enjoy eating. Reishi carries more bitterness on top of that, a forest bitterness that's simply part of the mushroom. That's why we went looking for a better way to make it. When we moved away from alcohol, the flavor got better, and honestly, so did the way it made us feel.
What to expect
The first day, the first weeks, and the long run
Everyone at the booth asks the same thing first. How fast will I feel it? Here is the honest answer, in the order it usually happens.
The first night
The one people notice first
Reishi is an evening one. Take it before bed and you may notice it that first night. Many people describe feeling settled rather than knocked out, which is the difference between this and something that sedates you. If your first night is unremarkable, that is normal, and it is worth staying with.
The first weeks
It stops being about one night
Same amount, same point in your evening. For most people this is where a good night stops being the exception and starts being the pattern.
A month in
It stacks
Sleep is the part you notice. The rest of what Reishi does is quieter and it builds with regular use. A month in you are not thinking about it, which is the point.
Which makes the next part the important part. Not the timeline. The habit.
What is Reishi Mushroom?
Reishi mushroom, also known as Ganoderma lucidum, is a type of fungus that grows on decaying logs and trees in various parts of Asia, including China, Japan, and Korea. The fruiting body (the part of the mushroom that we see above ground) is reddish-brown, kidney-shaped, and has a tough, woody texture .
Scientifically termed Ganoderma lucidum, its Chinese name, Lingzhi, signifies a powerful health elixir. Red Reishi, its vibrant variant, is cherished for its antioxidant properties. The Japanese call it Mannentake, while Yeongji is its Korean moniker. It has also earned the names Spirit Plant, the Mushroom of Immortality and Divine Mushroom.
History of Reishi Mushroom Use
Reishi has a rich history dating back over 2,000 years in traditional Chinese medicine, where it was highly revered for its numerous health benefits. Ancient texts describe the reishi mushroom as a "divine" and "auspicious" herb, and it was often reserved for royalty and the elite class (9). Today, reishi is gaining popularity worldwide as a natural and complementary approach to health and wellness.
Health Benefits of Reishi Mushroom
Reishi mushrooms contain a variety of bioactive compounds, including polysaccharides, triterpenoids, and peptides, that contribute to its health-promoting properties (9). Some of the key benefits of reishi mushroom are:
-
Immune System Support: Research has shown that reishi mushroom can help support the immune system by increasing the activity of certain white blood cells (8). This may help the body more effectively fight off infections and maintain overall health.
-
Antioxidant Properties: Reishi mushrooms are rich in compounds with antioxidant activity, which can help protect the body's cells from damage caused by free radicals (7).
-
Stress Relief and Sleep Improvement: Reishi mushrooms have been traditionally used to promote relaxation and improve sleep quality. Some research has shown that reishi may have adaptogenic properties, helping the body better cope with stress (9).
Reishi Mushroom and Whole-Body Organ Support: A Systems Biology Perspective
The therapeutic potential of Ganoderma lucidum, commonly known as Reishi, extends beyond general wellness claims. A close look through the lens of systems biology, biochemistry, and integrative physiology reveals that Reishi may offer targeted support to major organs and systems of the human body. Its influence spans hepatic detoxification, cardiovascular modulation, pulmonary function, renal support, and neuroendocrine balance. This section introduces the biological mechanisms through which Reishi interacts with these organ systems and lays the groundwork for in-depth cluster articles focused on each.
Reishi and Brain Health: Neuroprotection Through Mycological Modulation
Reishi (Ganoderma lucidum) has demonstrated a range of neuroprotective effects through several pathways associated with inflammation, oxidative stress, and neurotransmission regulation. Brain tissues are highly susceptible to oxidative damage due to their lipid-rich content and high metabolic demands. Reishi's triterpenoids, particularly ganoderic acids, and its abundant polysaccharides exert antioxidant activity by enhancing superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) levels within neural tissues (Wachtel-Galor et al., 2011).
Reishi may also influence the hypothalamic-pituitary-adrenal (HPA) axis by attenuating stress-induced cortisol elevation, which is critical for cognitive resilience and hippocampal preservation. In preclinical studies, Reishi extract reduced microglial activation and pro-inflammatory cytokines, including TNF-α and IL-1β, across brain regions implicated in memory and cognition (Zhu et al., 2012).
Moreover, polysaccharides from Reishi have been observed to increase brain-derived neurotrophic factor (BDNF) expression, a protein central to neurogenesis and synaptic plasticity. Reishi’s impact on the gut-brain axis also emerges through its prebiotic effects; by modulating gut flora and increasing SCFA production, it indirectly enhances neuroimmune function and neurotransmitter synthesis via enteroendocrine signaling pathways (Cryan et al., 2019).
Through a multifaceted approach—reducing inflammation, scavenging ROS, supporting neurotrophic signaling, and regulating stress physiology—Reishi demonstrates substantial potential as a neuroprotective adaptogen and cognitive modulator.
Reishi and the Digestive System: Gut-Immune Harmony Through Fungal Polysaccharides
Reishi’s interaction with the digestive system primarily occurs through its modulation of mucosal immunity, microbial ecology, and intestinal barrier function. Polysaccharides from Ganoderma lucidum serve as potent prebiotics, fostering beneficial bacteria such as Bifidobacterium and Lactobacillus species, which in turn enhance short-chain fatty acid (SCFA) production. SCFAs like butyrate are essential for epithelial cell repair, tight junction integrity, and anti-inflammatory cytokine expression (Zhou et al., 2015).
The gut-associated lymphoid tissue (GALT) houses over 70% of the body’s immune cells. Reishi’s polysaccharides stimulate dendritic cells and T-regulatory cells in the intestinal lamina propria, promoting immune tolerance and suppressing overactive immune responses. Animal studies demonstrate that oral Reishi administration increases levels of secretory IgA in the gut and normalizes CD4+/CD8+ T cell ratios, vital for intestinal immune homeostasis (Wang et al., 2012).
Reishi contains triterpenes, which may support a normal inflammatory response in the digestive tract. Furthermore, Reishi enhances the expression of tight junction proteins like ZO-1 and occludin, reducing intestinal permeability often implicated in metabolic endotoxemia and systemic inflammation (Li et al., 2020).
Reishi’s contribution to digestive health is not limited to physical barrier integrity. It also promotes neuromodulation via the gut-brain axis, indirectly influencing mood and cognition. This positions Reishi as a functional mycological intervention for comprehensive gastrointestinal regulation—from microbial modulation to immune surveillance and mucosal repair.
Hepatic (Liver) Function and Detoxification
The liver is the primary organ for detoxification, lipid metabolism, and hormonal balance. Numerous studies have documented the hepatoprotective effects of Reishi polysaccharides and triterpenoids. Mechanistically, these compounds reduce hepatic oxidative stress by enhancing the activity of endogenous antioxidant enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase.
Triterpenes from Reishi have shown the ability to modulate cytochrome P450 enzymes, especially CYP2E1, which plays a role in xenobiotic metabolism and is implicated in alcohol-induced liver damage (Wu et al., 2013). This modulation contributes to Reishi's protective effects against hepatotoxins such as carbon tetrachloride and alcohol.
Cardiovascular Regulation and Vascular Health
Reishi exhibits multiple cardioprotective effects, most notably through its influence on blood pressure regulation, cholesterol metabolism, and endothelial function. Ganoderic acids have been reported to inhibit angiotensin-converting enzyme (ACE) activity in vitro, suggesting a potential antihypertensive effect similar to pharmacological ACE inhibitors.
Reishi also contributes to favorable lipid profiles by downregulating hepatic HMG-CoA reductase activity, the enzyme responsible for cholesterol biosynthesis (Wachtel-Galor et al., 2011). Supplementation has been associated with reductions in LDL-cholesterol and triglycerides, alongside increased HDL levels in several clinical trials, albeit with small sample sizes.
At the endothelial level, Reishi polysaccharides enhance nitric oxide (NO) production by upregulating endothelial nitric oxide synthase (eNOS), which may improve vasodilation and reduce arterial stiffness.
Pulmonary Function and Immune Defense
The respiratory system, particularly the lungs, serves as both a site of gas exchange and a critical interface for immune defense. Reishi’s immunomodulatory effects are well-established, particularly its role in activating alveolar macrophages, increasing secretion of interleukin-1 (IL-1), and enhancing phagocytic activity.
Reishi is a source of beta-glucans, compounds studied for their role in supporting normal immune function.
Reishi's capacity to inhibit mast cell degranulation and reduce histamine release may further benefit individuals with chronic allergic respiratory conditions (Lee et al., 2010). These properties suggest a role in both prophylactic and adjunctive therapies for respiratory illnesses.
Renal (Kidney) Protection and Electrolyte Regulation
The kidneys regulate fluid balance, blood pressure, and waste elimination. Reishi contains antioxidant compounds, which may support the body's normal response to oxidative stress.
In rodent models of nephrotoxicity, Reishi supplementation has been shown to reduce serum creatinine and urea levels while preserving glomerular architecture.
Neurological and Endocrine Interactions
The brain and endocrine system are intricately connected through the hypothalamic-pituitary-adrenal (HPA) axis, a key modulator of stress response, mood, and homeostasis. Reishi’s adaptogenic potential is underpinned by its ability to normalize cortisol levels and influence the expression of stress-related proteins such as heat shock proteins (HSP70).
Neuroprotective effects of Reishi are largely attributed to its capacity to upregulate brain-derived neurotrophic factor (BDNF) and attenuate oxidative damage in neuronal tissues.

A Delicacy Fit for Emperors
When it comes to the edibility of reishi mushrooms, it's essential to know that they are not as readily consumable as other mushroom varieties. The only way to eat reishi mushrooms fresh is to consume the white growing margins of the cap while they are still in their developing stage. This tender part of the mushroom offers a unique culinary experience, which may explain why it was highly sought after by emperors in ancient China.
The lore of emperors indulging in reishi mushrooms is deeply rooted in traditional Chinese medicine. These potent fungi were believed to possess incredible healing properties, thanks to their rich array of bioactive compounds, such as polysaccharides, triterpenoids, and steroids. As a result, reishi mushrooms were considered an imperial delicacy, reserved for those with the highest stature in society.
