How QICAOGANGMU Works: Ingredients, Mechanisms and What the Research Shows
QICAOGANGMU is a steroid-free botanical topical built around five declared actives: Cnidii Fructus, Borneolum Syntheticum, Sophorae Flavescentis Radix, Stemonae Radix and Menthol. Modern studies on these ingredients explore itch signaling, inflammation, sensory pathways, microbial activity and topical delivery. The formula also uses glycerin and petrolatum to support moisture retention and the topical base.

Cnidii Fructus: the highest-concentration botanical active
Cnidii Fructus, called She Chuang Zi in Chinese herbal medicine, is present at 3%. Traditional materia medica describes external use for Dampness and itching. Modern research has examined compounds from Cnidium through several separate mechanisms.
One frequently studied constituent is osthole. In a 2018 experimental study, osthole inhibited the TRPV3 ion channel and reduced scratching behavior in mouse models. TRPV3 is involved in skin sensory signaling, making the finding relevant to research on itch pathways. PMID 30108138.
Cnidium has also shown antifungal activity in laboratory research. An aqueous extract inhibited Trichophyton rubrum, a dermatophyte associated with ringworm and athlete's foot. That is a useful positive antifungal finding for the herb, while also identifying the organism actually studied. PMC8417377.
Sophorae Flavescentis Radix: anti-inflammatory research
Sophorae Flavescentis Radix, or Ku Shen, is present at 1.5%. In TCM it is traditionally described as clearing Heat, drying Dampness, dispersing Wind and relieving itching. Modern pharmacology has investigated Sophora extracts and constituents including matrine, oxymatrine and sophoraflavanone G.
A 2024 study investigated Sophora flavescens in experimental psoriasiform inflammation and found anti-inflammatory activity from extracts and constituent compounds, together with work on topical skin targeting. This supports the scientific rationale for including Ku Shen in a topical botanical formula. PMID 38358770.
Other Sophora research spans cell and animal models, isolated compounds and different inflammatory conditions. Taken together, it gives the ingredient a substantial pharmacological research base without reducing the herb to one single pathway.
Borneolum Syntheticum: sensory effect and topical formulation research
Borneolum Syntheticum is present at 2%. Borneol has a long history in traditional formulations and is also studied in modern topical delivery systems. It can influence the stratum corneum environment and is frequently investigated as a penetration-enhancing component for co-formulated substances.
Human evidence also exists for topical sensory effects. In a randomized double-blind placebo-controlled study involving 122 postoperative patients, topical borneol produced greater pain relief than placebo. Related experimental work identified TRPM8 as an important sensory mechanism. PMC5452010.
Stemonae Radix: alkaloid and inflammation research
Stemonae Radix is present at 0.5%. The root contains a distinctive group of alkaloids that have been investigated for several biological activities. In a 2022 study of compounds isolated from Stemona tuberosa, researchers evaluated 29 alkaloids in an LPS-stimulated macrophage model. One compound showed clear inhibition of nitric oxide production and several others showed moderate activity. PMID 35295975.
This is experimental anti-inflammatory evidence at the isolated-compound level. It provides useful scientific context for Stemonae Radix while keeping the evidence type clear.
Menthol: why the cream feels cooling
Menthol is present at 0.5% and is responsible for much of the recognizable cooling sensation after application. Menthol activates TRPM8, a cold-sensing ion channel in peripheral sensory nerves. Cooling signals can change how itch, heat and discomfort are perceived at the skin surface.
The strength of the cooling sensation can vary with the amount applied, skin condition and individual sensitivity. Cooling itself is not proof of anti-inflammatory activity, but it is a real pharmacological sensory effect with a well-characterized receptor pathway.
Glycerin and petrolatum: the less glamorous but important base
QICAOGANGMU also contains glycerin and petrolatum. These are not traditional herbs, but they are important to how a topical cream behaves. Glycerin is a humectant that helps attract and retain water in the outer skin. Petrolatum is an occlusive ingredient that reduces water loss from the skin surface.
For dry or irritated skin, the vehicle can matter almost as much as the botanical actives. A cream that spreads evenly and reduces moisture loss creates a very different topical environment from applying powdered herbs directly to dry skin.
How the ingredients work together
The most useful way to understand QICAOGANGMU is not as five ingredients all doing the same job, but as a layered formula. The moisturizing base supports the skin surface. Menthol and borneol shape the immediate sensory experience. Cnidium and Sophora provide the strongest modern research around itch-related and inflammatory pathways among the declared botanicals. Stemona contributes a separate alkaloid research profile.
Current published research is strongest at the ingredient level, supported by longstanding traditional use in TCM. Ingredient studies help explain the scientific rationale behind the formulation and should be interpreted according to the type of evidence studied.
Traditional Chinese Medicine formulation logic
Within the traditional TCM framework, Ku Shen and She Chuang Zi are associated with concepts such as Wind, Dampness, Heat and itching. Borneol is traditionally used in multi-herb formulations and is valued for its aromatic, dispersing character. These traditional concepts describe the historical logic of the ingredients and are not biomedical synonyms for cytokines, fungi or nerve receptors.
That distinction is useful rather than limiting. It allows the same formula to be explained through two lenses: why the herbs were traditionally selected, and what modern research has found when extracts or compounds are studied experimentally.
Steroid-free formulation and purity testing
QICAOGANGMU's declared international formula does not list a corticosteroid ingredient. Its steroid-free formulation avoids corticosteroid-specific effects such as steroid-induced skin atrophy. Overall use should follow the product's directions and available safety information.
The product's Purity Assured information also publishes testing details. Where a laboratory report states "Not Detected," that result applies to the named substances in the tested panel at the laboratory's stated detection limit for that tested batch.
How to use the science when choosing a topical
Mechanism research is most helpful for understanding what an ingredient is plausibly doing, not for diagnosing the rash. Eczema, psoriasis, contact dermatitis, fungal infection, scabies and bacterial folliculitis can overlap visually. If the diagnosis is uncertain, clarifying the condition is more useful than choosing a cream only because one ingredient has an interesting pathway.

Frequently asked questions
Is QICAOGANGMU a steroid cream?
No corticosteroid is listed in the declared international ingredient formula. QICAOGANGMU is positioned as a steroid-free botanical topical, and testing information for named corticosteroids is published in the Purity Assured section.
What ingredient gives the strongest cooling sensation?
Menthol is the clearest cooling ingredient because it activates TRPM8 cold-sensing pathways. Borneol can also contribute to the sensory character of the formula.
Which ingredients have the most research behind them?
Sophora and Cnidium have broad modern pharmacological literatures spanning extracts and isolated compounds. Borneol also has a substantial topical and sensory research base. The strength and type of evidence vary by ingredient and by the exact extract or compound studied.
Why include petrolatum if the product is herbal?
Because a topical needs a functional vehicle. Petrolatum helps reduce water loss, while glycerin acts as a humectant. These base ingredients help create a usable cream and support dry skin at the surface.
