Antrodia camphorata, also called Antrodia cinnamomea or “niu-chang-chih,” is a rare fungus that grows only in Taiwan. Human research on it is limited to one small industry-funded trial in people with mildly elevated liver enzymes, which found improvements in liver markers after 12 weeks. Most of the supporting evidence comes from animal and lab studies, not large independent human trials, so the science is promising but still early.
Important Safety Notes Before You Read Further
This mushroom is marketed heavily for liver health, but that does not mean it is proven safe for everyone. Anyone with an existing liver condition, anyone taking prescription medication, and anyone scheduled for surgery should talk with a doctor or pharmacist before using any Antrodia product. Liver-active supplements can change how the liver processes certain drugs, and people with liver disease need medical supervision, not a supplement swap. Pregnant or breastfeeding people and children have no safety data available and should avoid use unless a clinician says otherwise. The National Center for Complementary and Integrative Health advises telling every health care provider about every supplement you use and remembering that “natural” does not automatically mean “safe” (NCCIH: Are You Considering a Complementary Health Approach?).

A Fungus That Only Grows on One Endangered Tree
Antrodia camphorata is not an ordinary mushroom. It is a parasitic fungus, meaning it lives off a living host rather than growing freely in soil or on dead wood. It grows only inside the trunk of Cinnamomum kanehirae, an aromatic camphor tree found only in Taiwan’s mountain forests, where it causes a condition called brown heart rot in the living tree.
This host relationship makes the fungus naturally scarce. Wild fruiting bodies once sold for as much as $15,000 per kilogram in 1997, before growers developed mycelium and solid-state cultivation methods to produce the fungus at scale. Because harvesting wild specimens damages or kills the host tree, most Antrodia products sold today come from cultivated mycelium, not wild harvest. Product labels rarely make this distinction clear, which matters for anyone trying to understand what they are actually buying. Taiwan’s Antrodia camphorata market is worth more than $100 million a year.
Traditional Use in Taiwan
In Taiwanese folk medicine, Antrodia camphorata has long been used as a general tonic and specifically as a remedy for hangover symptoms and liver discomfort after drinking. This traditional use is why almost all modern research on the fungus has focused on the liver, and specifically on alcohol-related liver stress, rather than on other body systems. Traditional use over generations is a reason to study a substance carefully. It is not, on its own, proof that a substance works or is safe by modern clinical standards.
What Human Clinical Research Actually Shows
There is one published randomized, double-blind, placebo-controlled human trial on an Antrodia camphorata extract standardized for antroquinonol content. It ran at multiple centers in Taiwan between December 2018 and November 2020 and is the closest thing to real clinical evidence this species has.
The trial enrolled adults aged 21 to 72 with elevated gamma-glutamyl transferase (GGT), a liver enzyme often raised by regular alcohol use. Eighty participants completed the study, 37 taking a 300 mg/day extract tablet and 43 taking a matching placebo, over 12 weeks. The group was 86% male. At 12 weeks, the treatment group showed statistically significant improvements compared to placebo in AST (p = 0.0365), ALT (p = 0.0230), and triglycerides (p = 0.0251), with no major safety differences between groups.
Two things matter for how you read this result. First, the study was funded by Golden Biotechnology Corporation, the company that makes the tested extract, and five of the paper’s authors were company employees, though the paper states the funder did not control the study design or analysis. Second, this was a small, short, mostly-male trial in people who already had elevated liver enzymes from alcohol use. It does not show that Antrodia camphorata benefits people with normal liver function, prevents liver disease, or treats any diagnosed liver condition. No larger, independently funded trial has replicated this result.
What Animal and Lab Research Shows
Outside that one human trial, the evidence base is entirely preclinical, meaning it comes from animal models or isolated cells in a lab dish, not from people. These studies help explain how the fungus might work biologically, but they cannot tell you what happens in a human body, and doses used in animals do not translate directly to human doses.
A rodent study testing Antrodia camphorata mycelium powder against alcohol-induced liver damage found that treated rats had lower ALT, AST, alkaline phosphatase, and inflammation markers than untreated alcohol-exposed rats, with effects at the highest dose comparable to silymarin, a reference liver-protective compound (PubMed: Hepatoprotective Effect of Antrodia camphorata Mycelium Powder on Alcohol-Induced Liver Damage). The same study noted that some other markers showed no significant change and that high concentrations were toxic to liver cells in the lab dish portion of the research, underlining that “natural” does not mean risk-free at every dose.
A separate lab and animal study found that antrodin C, a compound isolated from the fungus, reduced markers of liver fibrosis by blocking two signaling pathways involved in scar tissue formation (PubMed: Antrodia camphorata-Derived Antrodin C Inhibits Liver Fibrosis by Blocking TGF-Beta and PDGF Signaling Pathways). Other in-vitro and animal work has explored anti-inflammatory and antioxidant activity linked to liver protection. All of this research describes possible mechanisms. None of it has been confirmed in human liver fibrosis patients.
Evidence at a Glance
Human clinical trial (12 weeks)
Antroquinonol-standardized extract, 300 mg/day, in 80 adults with alcohol-related elevated liver enzymes. Result: lower AST, ALT, and triglycerides versus placebo. Strength: low to moderate; a single, short, industry-funded trial that has not been independently replicated.
Animal study: mycelium powder
Tested in rats against alcohol-induced liver injury. Result: reduced liver enzymes and inflammation, comparable to silymarin at the highest dose. Strength: preclinical only; not confirmed in humans.
Lab and animal study: antrodin C
Isolated compound tested in cell cultures and animal models. Result: reduced markers of liver fibrosis. Strength: preclinical mechanistic evidence only.
Lab study: mycelia extract and liver cancer cells
Tested in liver cancer cell lines and animal models. Result: suppressed STAT3 signaling linked to cancer cell growth. Strength: preclinical only; this is not evidence of a cancer treatment.
The Gap Between Tradition and Proof
Antrodia camphorata is one of the most heavily studied fungi in Taiwan, backed by a supplement market worth over $100 million a year in that country alone. That level of commercial and research interest can create a false impression of certainty. In reality, decades of traditional use and dozens of lab and animal papers have produced exactly one small human clinical trial, funded by the company that sells the tested extract. Strong preclinical interest is a reason for more independent human research, not a substitute for it.
If you see a product claim citing “clinical studies” on Antrodia camphorata, ask which study. The honest answer today is almost always the same 80-person, industry-funded, 12-week trial in people who already had elevated liver enzymes from drinking, not a body of independent evidence in the general population.
Who Should Use Extra Caution
- People with diagnosed liver disease, hepatitis, or a history of liver transplant, who need direct medical supervision, not a supplement.
- Anyone taking prescription medication, especially drugs processed by the liver, since interaction data for this fungus is not established.
- People preparing for surgery, since many supplements are advised to be stopped beforehand and this one has not been specifically studied for surgical safety.
- Pregnant or breastfeeding people and children, who were not included in the available research.
- Anyone using it to replace, delay, or avoid medical evaluation of ongoing liver symptoms such as jaundice, dark urine, unusual fatigue, or abdominal pain, which need prompt medical attention regardless of any supplement use.
Evidence Limits, Plainly Stated
Here is what the current research does not show: it does not show that Antrodia camphorata treats, cures, or prevents any liver disease. It does not show benefit in people with normal liver enzymes. It does not establish a safe or effective dose outside the one 12-week trial. It does not include long-term safety data beyond 12 weeks. And it does not come from research free of financial interest, since the only human trial was funded by the product’s manufacturer. Independent, larger, longer human trials are the missing piece.
Frequently Asked Questions
Is Antrodia camphorata proven to protect the liver in humans?
One small, industry-funded, 12-week trial found improved liver enzyme markers in people with alcohol-related enzyme elevation. That is early evidence, not proof, and it has not been independently replicated.
Is Antrodia camphorata the same as reishi or other medicinal mushrooms?
No. It is a separate species that grows only on one Taiwanese tree and has a much smaller and more Taiwan-centered research base than better-studied species like reishi.
Can I take Antrodia camphorata with my liver medication?
There is not enough interaction research to answer that safely. Anyone on liver-related medication should ask their prescribing doctor or pharmacist before combining it with any Antrodia product.
Does “wild” or “traditional” Antrodia work better than cultivated versions?
No published human research compares wild versus cultivated forms directly. Most products sold today are cultivated mycelium, and traditional reputation alone does not establish that wild-harvested material performs differently in the body.
