Mushrooms And Liver: What's The Connection?

Mushrooms can have both positive and negative effects on the liver. While some mushrooms are known to cause liver damage, others are believed to have hepatoprotective properties. For example, the Reishi mushroom has been associated with acute liver injury, especially when combined with alcohol consumption. On the other hand, medicinal mushrooms like Reishi, Chaga, and Cordyceps are said to support liver health and protect liver cells, especially in cases of cirrhosis. Additionally, certain mushroom extracts have exhibited hepatoprotective activities in animal studies, indicating their potential to prevent or reduce liver diseases. However, it is important to note that further research is needed to confirm the effectiveness and safety of using mushrooms for liver health.

Reishi mushrooms can induce acute liver injury when combined with alcohol

The liver is a complex organ that plays a central role in metabolism and the detoxification of waste products. While mushrooms have been reported to possess hepatoprotective properties, certain species can induce liver damage when consumed. For example, the species Amanita phalloides can cause acute liver failure, as evidenced by a case involving a 35-year-old female who experienced nausea, vomiting, abdominal pain, and palpitations after ingestion.

Reishi mushrooms (Ganoderma lingzhi) have been associated with acute liver injury, especially when combined with alcohol consumption. Case reports have shown that the unregulated Reishi mushroom supplement, when ingested with alcohol, can lead to varying degrees of hepatotoxicity. One such case involved a 47-year-old male who presented to the hospital with a headache and abdominal pain after consuming Reishi mushroom powder and alcohol. The patient was diagnosed with acute hepatitis and exhibited significant transaminitis, indicating liver inflammation.

The interaction between Reishi mushrooms and alcohol may have synergistic effects on liver injury. Reishi mushrooms have been shown to directly inhibit CYP2E1, a key enzyme in the metabolic pathway of ethanol. This inhibition can decrease the concentration of CYP2E1, leading to reduced ethanol metabolism and an increased risk of ethanol-induced hepatitis. The combination of Reishi mushroom powder and ethanol can potentially exacerbate elevated liver enzymes and bilirubin levels, as observed in some patients.

It is important to note that the patient's consumption of a significant amount of alcohol likely contributed to the liver injury. The abnormal ultrasound findings indicated fatty infiltration of the liver, which is a common consequence of excessive alcohol intake. The pattern of transaminitis observed in the patient also differed from typical alcoholic hepatitis, further suggesting the involvement of Reishi mushrooms in inducing acute liver injury. As a result of this incident, the patient was advised to discontinue the consumption of Reishi mushrooms and alcohol, and their symptoms resolved within two weeks.

Chaga mushrooms may prevent or treat certain liver diseases

While some mushrooms can induce liver damage, others have been shown to have hepatoprotective properties. For example, Antrodia cinnamomea has received attention for its potential health benefits, particularly its hepatoprotective effects against various drug-, toxin-, and alcohol-induced liver diseases. Ganoderma lucidum, the most studied medicinal mushroom, has also been shown to have protective activities against toxin-induced liver injury.

Chaga mushrooms, in particular, have been found to have potential therapeutic effects on liver fibrosis. Chaga extract has been shown to protect liver tissue from the effects of tetra-butyl hydroperoxide, a chemical known to cause liver damage. Chaga's anti-inflammatory properties have been demonstrated in several studies, indicating that it may help reduce inflammation and protect the liver. The antioxidants in chaga mushrooms may also reduce oxidative stress, which fuels chronic liver diseases like non-alcoholic fatty liver disease. Chaga is also rich in oxalates, however, which can increase the risk of kidney stones, so caution should be exercised when consuming chaga mushrooms.

Chaga mushrooms are available as a powder, extract, or herbal tea. They can be consumed by steeping small chunks or powdered chaga in hot water for several minutes to make a tea, or by taking pre-packaged tea bags or tinctures. Tinctures are concentrated liquid extracts that can be added to water, tea, or other beverages. Chaga supplements are also available in capsule or tablet form.

While the existing research on chaga mushrooms and liver health has primarily been conducted on animals or in vitro, the results suggest potential benefits for human liver health. Researchers are exploring the possibility that chaga mushrooms can prevent or slow the growth of cancer, including liver cancer. Chaga has also been shown to have antitumor, antiviral, antiplatelet, antidiabetic, antioxidant, analgesic, immunomodulating, anti-inflammatory, anti-allergic, and cognition-enhancing effects.

Certain mushrooms can cause catastrophic liver damage, resulting in acute liver failure

While mushrooms have been found to have several health benefits, certain species can induce catastrophic liver damage, resulting in acute liver failure. Mushroom poisoning, known as mycetism, is a pressing health concern worldwide. Although most mushroom ingestions are harmless, certain species like Amanita phalloides can cause severe liver damage. In one case, a 35-year-old female experienced nausea, vomiting, abdominal pain, and palpitations just six hours after consuming Amanita phalloides.

The identification of the specific mushroom species consumed is often challenging in poisoning incidents, emphasizing the need for clinical vigilance. It is crucial to recognize that while many mushroom exposures lead to mild gastrointestinal symptoms, some species can cause severe outcomes. Therefore, timely and effective intervention is paramount.

Reishi mushrooms (Ganoderma lingzhi) have been associated with acute liver injury, especially when combined with alcohol consumption. Case reports have linked Reishi mushroom use with episodes of fulminant hepatitis and inhibition of the CYP2E1 enzyme, which is crucial for metabolizing ethanol. The interaction between Reishi mushrooms and alcohol can potentially exacerbate liver damage.

On the other hand, some mushrooms have been found to have hepatoprotective effects. Antrodia cinnamomea, for instance, has been studied for its potential health benefits, particularly its ability to protect the liver against drug-, toxin-, and alcohol-induced liver diseases. Additionally, Chaga mushrooms have been found to prevent or reduce certain liver diseases. They exhibit powerful antioxidant properties and can protect liver tissue from damage.

Antrodia cinnamomea has hepatoprotective effects against various drug-, toxin-, and alcohol-induced liver diseases

Mushrooms have been studied for their potential to positively affect liver function. The most studied mushroom with respect to hepatoprotective effects is Ganoderma lucidum. However, the focus of this answer will be on Antrodia cinnamomea, as requested.

Antrodia cinnamomea, an edible fungus used in traditional medicine, has been found to have hepatoprotective effects against various drug-, toxin-, and alcohol-induced liver diseases. In a study by Liu et al. (2017), the components of A. cinnamomea (AC) mycelia were systematically analyzed, and its hepatoprotective effects were explored using a mouse model of acute alcohol-induced liver injury.

The study found that AC contains 25 types of fatty acids, 16 types of amino acids, 3 types of nucleotides, and 8 types of minerals. After two weeks of AC treatment at doses of 75 mg/kg, 225 mg/kg, and 675 mg/kg, the mouse model exhibited reduced levels of aspartate aminotransferase, alanine aminotransferase, oxidation-related factors, and inflammatory cytokines in serum and/or liver samples. AC treatment also resulted in a decreased incidence rate of necrosis, inflammatory infiltration, fatty droplets formation, and cell apoptosis in the liver, as detected by histological and TUNEL assays.

Furthermore, AC reduced the expression of cleaved caspase-3, -8, and -9, as well as the levels of phosphor-protein kinase B (Akt) and phosphor-nuclear factor-κB (NF-κB) in liver samples. The hepatoprotective effects of AC in mice with acute alcohol-induced hepatotoxicity are associated with the modulation of oxidative stress signaling.

The results of this study provide valuable evidence to support the use of A. cinnamomea as a functional food or medicine for liver protection. However, it is important to note that while mushrooms may have potential health benefits, certain species, such as Amanita phalloides, can induce catastrophic liver damage, leading to acute liver failure. Therefore, accurate identification of mushroom species is crucial to ensure safety.

Ganoderma lucidum is the most studied mushroom for its hepatoprotective effects

Mushrooms can have both positive and negative effects on the liver. While mushroom poisoning, or mycetism, can induce catastrophic liver damage, culminating in acute liver failure, certain mushrooms have been found to have hepatoprotective properties.

Ganoderma lucidum (G. lucidum) is the most studied mushroom for its hepatoprotective effects. It has been widely used for its health benefits as an edible and traditional medicinal mushroom for thousands of years in Asian countries, particularly in Japan and China. G. lucidum is currently used as a nutraceutical and functional food due to its major bioactive compounds, polysaccharides, and triterpenoids.

G. lucidum has been found to exhibit a broad range of hepatoprotective impacts in various liver disorders, such as hepatic cancer, non-alcoholic fatty liver disease (NAFLD), alcohol-induced liver disease, hepatitis B, hepatic fibrosis, and liver injury induced by carbon tetrachloride (CCl4) and α-amanitin. The mushroom protects the liver through a variety of mechanisms, including the modulation of liver Phase I and II enzymes, the suppression of β-glucuronidase, antifibrotic and antiviral actions, the regulation of nitric oxide (NO) production, the maintenance of hepatocellular calcium homeostasis, immunomodulatory activity, and scavenging free radicals.

The polysaccharides of G. lucidum, particularly β-glucans, improve immune system functioning and enhance immune cells' anticancer activities and cytokine production. Meanwhile, G. lucidum triterpenes inhibit cancer cell growth, proliferation, and invasion. The majority of mushroom polysaccharides are low in toxicity to the liver and have no major side effects, making them a popular natural remedy and functional food.

In summary, G. lucidum is the most studied mushroom for its hepatoprotective effects, with a wide range of potential benefits for the liver.
