Eczema, a chronic
inflammatory skin condition characterized by dry, itchy, and inflamed skin, is
a growing concern in the UK. According to the National Eczema Society, over 15
million people in the UK suffer from eczema, with 1 in 5 children and 1 in 10 adults affected.[1] The condition
not only impacts physical health but also significantly affects mental
well-being and quality of life. While Western medicine offers various
treatments, many patients seek alternative therapies, such as Chinese medicine,
to manage their symptoms effectively and holistically.
Western Medicine for Eczema: Challenges and Limitations
Western medicine primarily
treats eczema with topical corticosteroids, emollients, and antihistamines to
reduce inflammation, moisturize the skin, and relieve itching. In severe cases,
systemic immunosuppressants or biologics may be prescribed. While these
treatments can be effective, they often come with limitations and side effects.
Prolonged use of topical steroids, for example, can lead to skin thinning,
discoloration, and tolerance, while systemic treatments may carry risks of
immune suppression or organ toxicity.[2] These challenges have led
many patients to explore complementary and alternative therapies, especially traditional
Chinese medicine (TCM).
Chinese Medicine’s Understanding of Eczema
In Chinese medicine,
eczema is often attributed to an imbalance in the body’s internal environment,
particularly involving the Lung, Spleen, and Liver systems. According to TCM
theory, eczema is caused by a combination of factors, including:
- Wind, Heat, and Dampness: External pathogens like wind and heat, combined with
internal dampness, are believed to contribute to skin inflammation and
itching.
- Blood Deficiency:
Chronic eczema is often linked to blood deficiency, which leads to dry
skin and poor nourishment of the skin.
- Emotional Factors:
Stress and emotional imbalances are thought to exacerbate symptoms by
disrupting the flow of Qi (vital energy) and blood.
Chinese Medicine Treatment Methods
Chinese medicine
employs a holistic approach to treat eczema, focusing on addressing the root
cause of the imbalance rather than just alleviating symptoms. Common treatment
modalities include:
- Herbal Medicine:
Customized herbal formulas are prescribed based on the patient’s specific
pattern of imbalance. For example:
- Wind-Heat Pattern:
Herbs like Jin Yin Hua (Honeysuckle) and Lian
Qiao (Forsythia) are used to clear heat and expel wind.
- Damp-Heat Pattern:
Herbs such as Huang Qin (Scutellaria) and Fu
Ling (Poria) help resolve dampness and heat.
- Blood Deficiency Pattern: Herbs like Dang Gui (Angelica
Sinensis) and Shu Di Huang (Rehmannia) nourish the blood
and moisten the skin.
Commonly used formulas include Xiao Feng San (Wind-Dispelling
Powder) for acute eczema and Si Wu Tang (Four Substances
Decoction) for chronic cases.
- Acupuncture:
Acupuncture is used to regulate Qi and blood flow, reduce inflammation,
and relieve itching. Specific points, such as LI11 (Quchi)
and SP10 (Xuehai), are often targeted for skin
conditions.
- Dietary Therapy:
TCM emphasizes the role of diet in managing eczema. Patients are advised
to avoid damp-producing foods like dairy and sugar while incorporating
nourishing foods such as leafy greens and lean proteins.
- Topical Herbal Applications: Herbal creams or washes made from ingredients
like Ku Shen (Sophora) and Huang Bai (Phellodendron)
can soothe itching and reduce inflammation.
Efficacy of Chinese Medicine for Eczema
A Clinical
study showed that Xiaofeng San can reduce in total lesion scores in the
treatment group of eczema patients. It was significantly better than that in
the placebo group at 8 weeks. There were also statistically significant
differences between the treatment group and the placebo group in terms of
erythema, skin surface damage, itching, and sleep scores. Patients reported no
side effects of the treatment.[3]
A meta-analysis
study included a total of 662 patients with eczema were included (322 in the
experimental group and 340 in the control group). The area and severity index
and the remission rate of the treatment group were better than those of the
placebo group. The atopic dermatitis score, surface damage score, and sleep
score of the treatment group were all improved.[4]
Modern Pharmacological Research on Chinese Medicine
Modern research has
begun to validate the mechanisms behind TCM’s efficacy. For example:
- Huang Qin (Scutellaria)
has been found to contain baicalein, a compound with anti-inflammatory and
antioxidant properties.[5]
- Ku Shen (Sophora)
contains matrine, which has been shown to inhibit histamine release and
reduce itching.[6]
- Dang Gui (Angelica
Sinensis) promotes blood circulation and skin repair through its active
compounds, such as ferulic acid.[7]
These findings bridge
the gap between traditional knowledge and modern science, providing a
scientific basis for the use of Chinese medicine in eczema treatment.
Conclusion
Eczema is a complex
condition that requires a multifaceted approach to management. While Western
medicine provides effective symptom relief, its limitations and side effects
have led many patients to explore Chinese medicine as a complementary or
alternative therapy. With its holistic approach, personalized treatments, and
growing body of scientific evidence, Chinese medicine offers a promising option
for those seeking to manage eczema naturally and effectively.
