What's Actually Inside Tiger Milk Mushroom?
Tiger milk mushroom (Lignosus rhinocerus) gets its activity from the underground part of the fungus, the sclerotium, which is rich in three main groups of compounds: polysaccharides (including 1,3/1,6 beta-glucan), proteins, and triterpenoids, alongside fibre and minerals. Of these, the 1,3/1,6 beta-glucan is widely treated as the key active compound and the benchmark for quality.
If you have been reading labels at the pharmacy or comparing brands online in Malaysia or Singapore, this is the page that explains, in plain language, what those words on the box actually mean, and why some matter more than others.
What part of the mushroom is used?
The active part is the sclerotium, not the cap or stem. The sclerotium is a dense, tuber-like mass that grows underground and stores the plant's nutrients and defensive compounds.
This matters because most of tiger milk mushroom's studied compounds concentrate in the sclerotium rather than the fruiting body or the lab-grown mycelium. It is also why serious products state the sclerotium amount on the label. TYGRON™, for example, declares 1,000 mg of tiger milk mushroom sclerotium per sachet. If a product does not say which part it uses, that is a fair question to ask before you buy. We cover the difference in detail in our guide on fruiting body vs mycelium extraction.
What are the main active compounds in tiger milk mushroom?
The sclerotium contains several compound groups, but four are worth knowing:
- Polysaccharides: large sugar-chain molecules that make up a big share of the sclerotium. The most studied of these is beta-glucan.
- 1,3/1,6 beta-glucan: a specific type of polysaccharide with a particular branching structure. This is the headline active compound and the usual quality benchmark.
- Triterpenoids: a family of plant compounds found across many medicinal mushrooms and herbs, present here in smaller amounts.
- Proteins and small peptides: including a lectin-type protein that researchers have isolated and studied from the sclerotium.
Beyond these, the sclerotium also carries dietary fibre, minerals, and trace amounts of other natural constituents. The exact balance varies with how the mushroom is grown, harvested, and processed, which is one reason a lab-verified beta-glucan figure is more useful than a long ingredient list.
| Compound | Role |
|---|---|
| Polysaccharides (incl. 1,3/1,6 beta-glucan) | Large sugar-chain molecules that make up a big share of the sclerotium; beta-glucan is the headline active compound and quality benchmark. |
| Triterpenoids | A family of plant compounds found across many medicinal mushrooms and herbs; present here in smaller amounts. |
| Proteins and small peptides | Include a lectin-type protein that researchers have isolated and studied from the sclerotium. |
| Fibre and minerals | Dietary fibre and trace minerals that round out the natural profile of the sclerotium. |
Why is 1,3/1,6 beta-glucan the one to look at?
1,3/1,6 beta-glucan is the most important active compound and quality benchmark in tiger milk mushroom: a higher content signals greater potency and quality.
The “1,3/1,6” refers to how the sugar units are linked together. It is this specific branched structure that researchers focus on when they study mushroom beta-glucans, and it is the structure that distinguishes a quality sclerotium from a thin one. Because it is measurable, beta-glucan content is the single most honest number to compare between brands, far more telling than vague phrases like “high potency”.
This is why TYGRON™ holds the Malaysia Book of Records certification for the highest 1,3/1,6 beta-glucan content in Malaysia, verified by accredited laboratory analysis. We explain the structure and why it matters in full in beta-glucan in tiger milk mushroom, explained.
Quick rule of thumb: if a brand cannot tell you its beta-glucan content or point to independent verification, the number on the front of the box is just marketing.

What about triterpenoids and the other compounds?
Triterpenoids are a well-known group of compounds across functional mushrooms and many traditional botanicals. In tiger milk mushroom they are present in smaller amounts than the polysaccharides, and they form part of the overall profile of the sclerotium rather than being the star.
The lectin-type proteins are mostly of research interest: scientists have isolated and characterised them to understand the mushroom better. For everyday use, the polysaccharide fraction and its beta-glucan content remain the practical thing to look at.
Does the body actually absorb these compounds?
Having good compounds in the box is only half the story; absorption is the other half. Large molecules like polysaccharides are not always easy for the body to take up efficiently, which is where formulation comes in.
ORGANO™ uses Herbosomal® patented liposomal encapsulation technology (patent number MY-188945-A) on the extract portion of TYGRON™ to support absorption. In plain terms, encapsulation wraps the active extract in a fat-friendly carrier that the body recognises and takes up more readily. We break down how this works in Herbosomal® absorption, explained.
What does the research say about these compounds?
Tiger milk mushroom has a long heritage. It has been used by the Orang Asli and across Malaysian traditional practice for respiratory complaints for generations: a heritage of use, not a claim of treatment.
On the modern side, a preliminary open-label study published in Scientific Reports (Tan ESS, Leo TK, Tan CK, 2021; DOI 10.1038/s41598-021-91256-6) reported improvements in lung-function markers, nasal comfort, and antioxidant status in healthy adults taking a tiger milk mushroom product over three months. It is worth being clear about what that study was: open-label, with no placebo group, in a small group of healthy volunteers, and it used a different product, so the findings are early and should be read as preliminary rather than proof.
Separately, preclinical safety work on the sclerotium found it was generally well tolerated in animal studies, with no treatment-related toxicity observed over 28 days of oral dosing (Lee SS, Tan NH, Fung SY, et al., Journal of Ethnopharmacology, 2011; PMID 21930194). This supports the long-standing view that the sclerotium is well tolerated, while not being a substitute for talking to your own doctor.

Frequently asked questions
What is the main active compound in tiger milk mushroom?
1,3/1,6 beta-glucan, a type of polysaccharide found in the sclerotium, is widely treated as the main active compound and the quality benchmark. A higher beta-glucan content signals greater potency and quality.
Is beta-glucan the same as polysaccharide?
Beta-glucan is a specific kind of polysaccharide. Polysaccharide is the broad family of long sugar-chain molecules; 1,3/1,6 beta-glucan is one particular branched structure within that family, the one researchers focus on in tiger milk mushroom.
Which part of tiger milk mushroom contains the active compounds?
The sclerotium, the dense underground storage body, holds most of the studied compounds, not the cap or stem. Quality products state the sclerotium amount on the label; TYGRON™ declares 1,000 mg of tiger milk mushroom sclerotium per sachet.
What are triterpenoids and do they matter?
Triterpenoids are a group of natural compounds found across many functional mushrooms and herbs. In tiger milk mushroom they are present in smaller amounts than the polysaccharides, so they are part of the overall profile rather than the headline compound.
How do I know a product has enough active compound?
Look for a stated, lab-verified 1,3/1,6 beta-glucan content and which part of the mushroom is used. Independent verification, such as the Malaysia Book of Records certification TYGRON™ holds for the highest beta-glucan content in Malaysia, is more reliable than front-of-box phrases like “high potency”.
Is tiger milk mushroom safe to take daily?
Tiger milk mushroom has a long heritage of daily use and was generally well tolerated in preclinical safety studies. As with any functional food, if you are pregnant, nursing, or taking medication, check with your doctor first.
