Tiger Milk Mushroom: Benefits, Side Effects and Uses for Respiratory Health
Tiger Milk Mushroom is gaining attention in Malaysia and internationally for its potential respiratory, immune-supporting and antioxidant properties.
Traditionally used in Southeast Asian medicine, this rare medicinal fungus has now been examined in clinical and preclinical studies for its possible effects on lung function, respiratory symptoms, inflammation and immune defence.
In this guide, we explore what Tiger Milk Mushroom is, how it may support respiratory health, its potential side effects and who should seek medical advice before taking it.
What Is Tiger Milk Mushroom?
Tiger Milk Mushroom, scientifically known as Lignosus rhinocerus, is a medicinal fungus traditionally used by indigenous communities across Southeast Asia.
In Malaysia, it is commonly known as cendawan susu rimau or kulat susu rimau. Both names translate to “Tiger Milk Mushroom.”
Historically, the term may also have been used to describe other closely related species within the Lignosus genus, including Lignosus tigris and Lignosus cameronensis, because their underground structures look similar.
Tiger Milk Mushroom grows naturally in tropical rainforest regions, including Malaysia, Thailand and parts of China.
Unlike many familiar mushrooms, the most commonly used part is not the visible fruiting body. Instead, supplements are generally produced using the sclerotium, a firm, tuber-like structure formed from densely packed fungal material.
The sclerotium acts as a nutrient reserve for the fungus and contains many of the naturally occurring compounds being studied for their potential health-supporting properties.
Tiger Milk Mushroom also has a long recorded history. A fungus believed to be Tiger Milk Mushroom was mentioned approximately 400 years ago in The Diary of John Evelyn, after specimens were reportedly brought to Europe by Jesuits travelling from Asia.
Potential Benefits of Tiger Milk Mushroom
1. May Support Respiratory Health and Lung Function
One clinical study examined the effects of Tiger Milk Mushroom supplementation in 50 adult volunteers.
Participants consumed 300 mg of Tiger Milk Mushroom twice daily for three months. At the end of the study, researchers reported significant improvements in several measurements of pulmonary function.
Forced expiratory volume in one second, commonly known as FEV1, improved by approximately 19.7%.
FEV1 measures how much air a person can forcefully exhale during the first second of a breath. It is commonly used to assess airflow and respiratory function.
The ratio of FEV1 to forced vital capacity, or FEV1/FVC, increased from 67.40 to 85.73, representing an improvement of approximately 27.2%.
These findings suggest that consistent Tiger Milk Mushroom supplementation may help support overall respiratory function in adults.
However, the study was relatively small, and larger controlled trials are still needed to confirm the results across different populations.
2. May Help Improve Respiratory and Nasal Symptoms
The same clinical study evaluated participants using the Nasal Symptom Questionnaire, or NSQ.
After three months of supplementation, the average NSQ score decreased from 8.96 to 2.32. This represented an overall change of approximately 74.1%.
Participants also completed a Visual Analogue Scale to assess the severity of their symptoms. The average score decreased from 2.54 to 0.68 by the end of the study.
These improvements suggest that Tiger Milk Mushroom may help support people experiencing certain nasal and respiratory discomforts.
The study did not establish that Tiger Milk Mushroom can diagnose, treat or cure a respiratory condition. Its findings should be understood as evidence of potential supportive benefits rather than a replacement for medical treatment.
3. May Support a Balanced Inflammatory Response
Inflammation is part of the body’s natural defence system. However, prolonged or excessive inflammation may contribute to ongoing irritation in the respiratory tract.
Researchers found that Tiger Milk Mushroom supplementation was associated with reductions in two pro-inflammatory signalling molecules:
- Interleukin-1 beta, or IL-1β, decreased by approximately 54.9%.
- Interleukin-8, or IL-8, decreased by approximately 40.8%.
Both IL-1β and IL-8 are involved in inflammatory activity within the airways and lungs.
Preclinical studies have also reported anti-inflammatory activity from extracts of the Lignosus rhinocerus sclerotium.
Together, these findings suggest that Tiger Milk Mushroom may help support a healthy inflammatory response. More human research is needed to determine how clinically meaningful these changes are.
4. May Support Respiratory Immune Defence
Tiger Milk Mushroom may also help support the immune system at the body’s mucosal surfaces.
In the clinical study, participants experienced an increase in immunoglobulin A, commonly known as IgA.
Average IgA levels increased from 4.83 ng/mL to 10.26 ng/mL after three months of supplementation.
IgA is an antibody found in saliva and other mucosal secretions. It acts as part of the body’s first line of defence by helping protect exposed surfaces in the nose, throat, airways and digestive tract.
The increase observed in the study suggests that Tiger Milk Mushroom may support respiratory immune defence. It does not mean the supplement can prevent or cure infections.
5. May Increase Antioxidant Capacity
Oxidative stress occurs when the production of unstable molecules, known as free radicals, exceeds the body’s antioxidant defences.
Environmental pollution, cigarette smoke, inflammation and normal metabolic activity may all contribute to oxidative stress.
In the clinical study, participants’ total antioxidant capacity increased from 0.703 mmol/L to 1.188 mmol/L. This represented an improvement of approximately 68.9%.
Researchers also measured malondialdehyde, or MDA, which is commonly used as an indicator of oxidative damage to fats within the body.
MDA levels decreased from 1.10 nmol/L to 0.34 nmol/L, representing a reduction of approximately 68.3%.
These results suggest that Tiger Milk Mushroom may help strengthen the body’s antioxidant defences and reduce markers associated with oxidative stress.
6. Other Potential Benefits Being Studied
Scientific reviews of Tiger Milk Mushroom and related Lignosus species have discussed a wide range of possible biological activities.
These include potential:
- Antioxidant activity
- Anti-inflammatory activity
- Respiratory-supporting effects
- Immune-modulating activity
- Neuroprotective effects
- Skin-protective effects
- Healthy-ageing support
- Blood-glucose support
- Wound-healing activity
Some laboratory studies have also explored anticancer, antiviral and anti-HIV properties.
However, many of these findings come from laboratory or animal studies rather than large human clinical trials. They should not be interpreted as proof that Tiger Milk Mushroom can prevent, treat or cure these conditions.
Does Tiger Milk Mushroom Have Side Effects?
Available preclinical research suggests that Tiger Milk Mushroom has demonstrated a relatively favourable safety profile at the doses tested.
In one 28-day animal toxicology study, rats received up to 1,000 mg per kilogram of body weight daily. Researchers reported no treatment-related sub-acute toxicity.
The study established a no-observed-adverse-effect level, or NOAEL, above 1,000 mg per kilogram.
Another 28-day study involving the sclerotium of Lignosus tigris also found no significant treatment-related adverse effects at oral doses of up to 1,000 mg per kilogram per day.
Although some statistically significant changes were observed in blood and biochemical measurements, researchers did not consider them to be caused by the treatment.
It is important to remember that animal safety studies cannot fully predict how every person will respond.
Possible supplement-related reactions may include:
- Digestive discomfort
- Nausea
- Bloating
- Headache
- Sensitivity or allergic reactions
Anyone who develops unusual or persistent symptoms should stop taking the supplement and consult a healthcare professional.
Who Should Consult a Healthcare Professional First?
Speak with a doctor, pharmacist or qualified healthcare professional before taking Tiger Milk Mushroom if you:
- Are pregnant or breastfeeding
- Are under 18 years old
- Have a mushroom or fungal allergy
- Have a chronic health condition
- Are preparing for surgery
- Take prescription medicines
- Use blood-thinning, immune-suppressing or blood-glucose medications
- Are currently receiving treatment for a respiratory condition
Tiger Milk Mushroom should complement appropriate medical care, not replace prescribed medication, inhalers or professional medical advice.

Check whether the product contains the sclerotium, mycelium, fruiting body or a combination.
Most traditional use and current research surrounding Tiger Milk Mushroom focus on the sclerotium.
Clearly Stated Dosage
Choose products that disclose the amount of Tiger Milk Mushroom provided per serving.
Avoid relying solely on vague claims such as “proprietary mushroom blend” without a clear ingredient quantity.
Manufacturing Standards
Look for products manufactured in facilities that follow recognised quality and safety standards.
Supporting Ingredients
Some formulations combine Tiger Milk Mushroom with other mushrooms, herbs, fruits, prebiotics or vitamins.
Review the complete ingredient list carefully, especially if you have allergies, sensitivities or take medication.
Frequently Asked Questions
Is Tiger Milk Mushroom Good for the Lungs?
Clinical findings suggest that Tiger Milk Mushroom may support lung function, respiratory comfort and mucosal immunity.
In one three-month study, supplementation was associated with improvements in FEV1, the FEV1/FVC ratio, respiratory symptom scores, IgA levels and inflammatory markers.
These findings are promising, but Tiger Milk Mushroom should not be considered a treatment or cure for lung disease.
Is Tiger Milk Mushroom Suitable for Children?
The main clinical study discussed involved adult participants.
There is currently insufficient information from the available research to confirm an appropriate dosage or safety profile for children.
Parents should consult a paediatrician or qualified healthcare professional before giving Tiger Milk Mushroom to a child.
Can Tiger Milk Mushroom Help With Sinus Issues?
The clinical study used the Nasal Symptom Questionnaire to evaluate nasal and respiratory symptoms.
Participants showed significant improvements after three months of supplementation. These changes may be connected to Tiger Milk Mushroom’s potential anti-inflammatory and immune-supporting effects.
However, targeted clinical studies specifically investigating sinus conditions are still limited.
How Long Does Tiger Milk Mushroom Take to Work?
The clinical findings discussed were measured over a three-month supplementation period.
Individual experiences may vary depending on dosage, formulation, general health, consistency of use and the reason for taking the supplement.
Tiger Milk Mushroom is generally positioned as a daily nutritional supplement rather than an immediate-relief product.
Can Tiger Milk Mushroom Replace an Inhaler or Medication?
No.
Tiger Milk Mushroom should not replace an inhaler, prescription medicine or treatment plan recommended by a healthcare professional.
People taking respiratory medication should continue following their doctor’s instructions and discuss any new supplement before adding it to their routine.
Final Thoughts
Tiger Milk Mushroom has a long history of traditional use in Southeast Asia, particularly for respiratory and general wellness support.
Early clinical evidence suggests that it may support pulmonary function, respiratory comfort, mucosal immunity, antioxidant capacity and a healthy inflammatory response.
However, research is still developing. Many potential benefits require further investigation through larger, placebo-controlled human studies.
For adults seeking additional nutritional support for respiratory and immune health, Tiger Milk Mushroom may be worth considering as part of a broader wellness routine.
Always choose a clearly labelled, quality-controlled product and consult a healthcare professional if you take medication, have an existing medical condition or are unsure whether the supplement is suitable for you.
