The liver is the largest internal organ in the human body. It performs many, many functions including:-
- Metabolism and storage of food
- Conversion and transportation of medicine
- Detoxification and excretion of toxic substances ingested or inhaled
- Synthesis of protein
- Involvement in food digestion (conversion of hemoglobin into bilirubin to aid digestion).
Main Causes of Liver Diseases
Damage to liver cells may result in liver inflammation, hepatitis, fibrosis, cirrhosis or cancer.
The 3 main causes of liver disease are:-
- viral infection, where the most prevalent are hepatitis B and C (AST/ALT ratio less than 1).
- alcoholic damage (AST/ALT ratio more than 2).
- chemical damage including ingestion or inhalation of toxic substances.
Once liver cells are damaged, they will release GPT (ALT) and GOT (AST) enzymes - the greater the damage, the higher the values of these liver function indices. GPT is a more representative index on account of its liver specificity. GOT also exists in the heart, kidneys, skeletal muscle and brain.
Research into the Effects of Ganoderma on Liver Function
Over 30 scientific studies have been published on the usage of ganoderma in liver protection. These are some of the references on studies published since 2000:
An official testing method uses a strict and rigorous approach employing a "chronic poisoning" model, which involves using carbon tetrachloride to induce chronic hepatic injury in rats. This requires 8 weeks of feeding the toxic substances to rats and examining their effects on the liver. The rats are divided into 5 groups:
a) control group (no medication given)
b) carbon tetrachloride (CCl4) group
c) silymarin group
d) low-dosage ganoderma group
e) high-dosage ganoderma group.
The results are as follows:
The test results show that rats receiving ganoderma products (extracted from YK-01 strain) showed significant decreases in GPT and GOT values after 3 weeks. This shows that ganoderma was able to reduce hepatic injury induced by CCl4. The efficacy is dose-dependent. i.e. the more ganoderma was taken (from 0.5g/Kg to 3.0g/Kg), the more the inflammation was alleviated and liver function indices lowered. Thus, in animal testing model for lowering serum GPT and GOT values, ganoderma extract has the effect of alleviating injuries related to the liver.
When the liver is injured, it will activate the function of liver cell regeneration. The experiment found that mice taking CCl4 together with ganoderma were found to have high levels of protein in their livers. This tendency is also dose-dependent - higher dosage (0.5g/Kg to 3.0g/Kg) of ganoderma led to greater levels of liver protein. Ganoderma is not a high-protein food, but interestingly, the results demonstrated that it helped to increase the quantity of protein in the liver. The liver cells also show greater powers of regeneration. In other words, ganoderma can increase the quantity of protein in the liver, and enhance liver cell reproduction.
This study was published in the The American Journal of Chinese Medicine in 2004.

This test results shows the effects of ganoderma and silymarin in reducing hepatic fibrosis:
Section A : Healthy liver
Section B : Clear signs of fibrosis.
Section C : High-dosage ganoderma group showed no signs of fibrosis.
Section D : Silymarin group showed a lower level of hepatic fibrosis.

In another study in 2006, Bi-Fong Lin and Miao-Ling Chen from National Taiwan University fed ganoderma extracts from the fruiting body of the YK-01 strain to mice for 7 weeks. The results indicate that ganoderma has anti-oxidation ability, i.e. prevent our liver from oxidation.
In 2005, Prof. Jin-Kun Wang from Chung Shan Medical University conducted a clinical trial on 40 healthy volunteers using Ganoderma YK-01 fruiting body extracts over 3-6 months. Their average GPT values during consumption of ganoderma were measured and are listed in the table below:
In other words,
- YK-01 ganoderma extract decreases liver indices values.
- The longer the extract is used, the more the hepatic GPT value dropped.
Summary
Ganoderma provides "all-round" liver protection because:
- It helps to protect the liver from harm by reducing injuries related to the liver.
- In the case of injury, ganoderma promotes liver cell reproduction.
