Tradition meets research
A modern presentation of a TCM-inspired composition
The formula combines botanical extracts, a medicinal mushroom and bee pollen. Many of these raw materials have a long history in Asian medical traditions; modern research mainly investigates their phytochemicals, polysaccharides, alkaloids and ginsenosides.

- Direct links to original scientific publications
- Clear labelling of human and preclinical evidence
- No implication that the complete product has been clinically tested
Selected ingredients
Key components of IMUSAN
Four familiar components illustrate the breadth of the formula. The complete daily composition is listed immediately below.

Ginseng
Ginsenosides are among the most extensively studied constituent groups in ginseng.
36 mg extract · 5.4 mg ginsenosides
Ganoderma lucidum
Reishi
This mushroom contains polysaccharides and triterpenes, among other compounds; human evidence remains limited.
72 mg · 10:1 extract
Corydalis yanhusuo
Corydalis
Alkaloids such as dehydrocorydaline are investigated in preclinical studies of cellular signalling.
72 mg · 10:1 extract
Glycyrrhiza glabra
Liquorice root
Research includes glycyrrhetinic acid and flavonoids such as isoliquiritigenin.
9 mg · 10% extractFull transparency
Daily serving: 3 capsules

Scientific context
What studies on individual ingredients report
Some components have been examined in small human studies; for many rare TCM extracts, evidence is largely limited to laboratory or animal models.
Important: The linked papers investigate individual plants, extracts or isolated substances—not IMUSAN as a complete product. Extract type, dose, duration and study population differ. Preclinical findings do not prove an effect in humans.
Human studyPreclinical / laboratory
Human study
2002
Green tea extract & antioxidant markers
A blinded crossover study in 16 men examined green tea extract after a low-flavonoid diet. Measured antioxidant capacity rose transiently after meals, while no persistent fasting effect was demonstrated.
Context
Open original publication · PMID 12064344 ↗
Small sample, short duration and a different catechin dose; no evidence for disease outcomes or for IMUSAN.
Human study
2021
Red ginseng & immune-cell counts
In a randomised double-blind trial, 100 adults took 2 g Korean Red Ginseng or placebo daily for eight weeks. T-cell, B-cell and white-blood-cell counts increased in the ginseng group; cold incidence did not differ significantly.
Context
Open original publication · PMID 33437171 ↗
The study product and dose are not equivalent to the 36 mg ginseng extract in IMUSAN.
Human study
2004
Reishi & short-term antioxidant capacity
A small double-blind crossover study in healthy adults observed short-term increases in plasma and urinary antioxidant capacity after Reishi intake. Clinical outcomes were not assessed.
Context
Open original publication · PMID 14630595 ↗
Very small sample, short exposure and substantially higher Reishi amounts than the IMUSAN daily serving.
Preclinical
2016
Agrimonia pilosa & inflammatory signalling
In LPS-stimulated macrophages, isolated agrimonolide reduced pro-inflammatory mediators and influenced COX-2, iNOS, MAPK and NF-κB pathways.
Context
Open original publication · PMID 27288920 ↗
A cell model using an isolated compound; it does not establish an oral effect of the extract in humans.
Preclinical
2020
Corydalis & NF-κB signalling
In cultured macrophages, Corydalis extracts and alkaloids such as dehydrocorydaline reduced TNF-α and IL-6 release and inhibited NF-κB activation.
Context
Open original publication · PMID 33299450 ↗
Laboratory evidence only; concentrations and bioavailability cannot be transferred to IMUSAN intake.
Preclinical
2019
Liquorice & molecular inflammatory markers
Liquorice extract and selected constituents reduced nitric-oxide production and the expression of TNF-α, COX-2 and iNOS in a macrophage model, partly involving NF-κB.
Context
Open original publication · PMID 31083310 ↗
In-vitro evidence. Liquorice may also require particular caution with certain conditions and medicines.
Preclinical
2020
Pyrola rotundifolia & antioxidant assays
A phytochemical laboratory study characterised phenolic compounds in the leaves and measured antioxidant activity in chemical test systems.
Context
Open original publication · PMID 32290223 ↗
Chemical assays are not human studies and cannot demonstrate a health benefit after oral use.
Preclinical
2014
Isodon rubescens / oridonin
Oridonin, a constituent of Isodon rubescens, reduced glial activation, inflammatory mediators and NF-κB signalling in a mouse model.
Context
Open original publication · PMID 25121593 ↗
An animal model using an isolated compound; no direct transfer to humans or to the included 20:1 extract.
