The big idea:
This article reviews existing scientific evidence on Chinese herbal medicine for atopic dermatitis (eczema) and concludes that while some studies show potential benefits, overall evidence remains limited and inconclusive.
What the study asked:
The article sought to examine whether Chinese herbal medicine is an effective and safe treatment option for atopic dermatitis (AD), a chronic, relapsing inflammatory skin condition commonly associated with itching, sleep disturbance, and reduced quality of life.
Since many patients — especially in Asia — seek alternative or complementary therapies due to concerns about long-term steroid use and the lack of a definitive cure, the authors aimed to evaluate the strength of current scientific evidence supporting Chinese medicine for eczema.
What the study did:
The authors conducted a literature review using databases such as PubMed and the Cochrane Database for Systematic Reviews.
They searched for randomized controlled trials (RCTs), case series, and laboratory (bench) studies that investigated Chinese herbal medicine for eczema.
They included studies involving both children and adults and examined clinical outcomes such as symptom severity, quality of life, steroid usage, and laboratory markers of immune function.
They also reviewed studies on possible mechanisms of action and reported adverse effects.
What the study found:
The review identified only a small number of well-designed randomised controlled trials.
Some herbal formulations, such as Zemaphyte and PentaHerbs, showed improvements in eczema severity scores or reductions in the need for topical corticosteroids in certain trials.
For example, some studies reported significant reductions in symptom severity and improved quality of life, while others found reduced steroid usage among patients taking herbal formulations.
However, results were inconsistent.
While early trials in the UK showed positive effects of Zemaphyte, later trials in Hong Kong did not demonstrate significant benefits compared to placebo.
Similarly, studies on PentaHerbs showed improvements within treatment groups, but differences between treatment and placebo groups were sometimes not statistically significant.
Some trials suggested that herbal treatments may help improve quality of life even when changes in clinical severity were modest.
Laboratory studies provided some biological support for these findings.
Certain herbal formulations appeared to reduce inflammatory markers, modulate immune responses (such as lowering Th2 cytokines), and inhibit mast cell activation, which may contribute to reduced inflammation and itching.
However, these mechanistic findings do not automatically confirm strong clinical effectiveness.
The review also highlighted safety concerns.
Although many studies reported no serious adverse effects, there have been case reports of liver damage and other complications associated with Chinese herbal medicine.
Standardization of herbal mixtures remains a challenge, and safety monitoring is essential.
What this means for eczema:
Chinese herbal medicine may offer potential benefits for some individuals with eczema, particularly as an adjunct to conventional treatment.
It may improve symptoms, reduce steroid dependence, or enhance quality of life in certain patients.
However, current evidence is limited by small sample sizes, inconsistent results, and methodological weaknesses.
Therefore, Chinese herbal medicine cannot yet be considered a proven or first-line treatment for eczema.
Larger, well-designed clinical trials are needed to confirm its effectiveness and ensure safety before it can be widely recommended in standard medical practice.
