Many eczema sufferers try complementary therapies, particularly homeopathy, acupuncture or special diets.
Clinical bottom line
Likely to be beneficial
Probiotics: Reduce symptoms in infants and children.
Zemaphyte: A Chinese herbal mixture, which may reduce skin lesions but results are not entirely uniform.
Autogenic training: Effects on itching, long-term results are encouraging but not enough data available.
Autologous blood therapy: Not enough data available.
Biofeedback: Effects on itching, severity of skin lesions: not enough data available.
Black seed (Nigella sativa) oil: Not enough data available.
Borage (Borago officinalis) oil: Conflicting results.
German camomile (Matricaria recutita): Not enough data available on topical preparation.
Hypnotherapy: Not enough data available.
Johrei healing: Data unconvincing and scarce.
Liquorice (Glycyrrhiza glabra): Topical gel, not enough data available.
Selenium: Results contradictory.
Shuangfujin (Chinese herbal remedy): Not enough data available.
St John's wort (Hypericum perforatum): Topical, not enough data available.
Likely to be ineffective or harmful
Evening primrose (Oenothera biennis) oil: Initial positive studies were superseded by more rigorous negative trials.
Massage: No evidence of effectiveness.
Zinc: No evidence of effectiveness.
Probiotics and the Chinese herbal mixture Zemaphyte may be effective. Only Zemaphyte is associated with serious risks.
For probiotics, the risk–benefit balance is likely to be positive. Conventional treatments are probably more effective than complementary and alternative medicine.
