M.Tech. (Homoeopathy) / Atopic dermatitis (atopic eczema) is a chronic, relapsing, allergic inflammatory skin disease (Hauk, 2008). The prevalence of atopic dermatitis has increased significantly over the past few decades, with highest rates of 45 – 64% occurring amongst preschool children (Butler, 2009), and 40% amongst older children and adults (Manjra, 2005). This increase in prevalence is attributed to environmental factors such as microbial exposure and poor nutrition, which can all lead to atopic dermatitis (Schnopp, 2006). The quality of life of patients suffering from atopic dermatitis and their family members are significantly affected (Manjra, 2005). Atopic dermatitis is characterized by active skin lesions that are red, flaky, dry and itchy and in children commonly occurs in the flexural areas of the body (Fölster-Hols et al., 2007, Schnopp, 2006). Conventional treatment potions for atopic dermatitis are associated with adverse effects in children (Kalicharan et al., 2005). Homoeopathic remedies may offer an alternative option for this condition. This study aimed to assess the effect of a homoeopathic complex consisting of Graphites 6cH, Histaminum 9cH, Psorinum 6cH and Sulphur 6cH, on atopic dermatitis in children. All the participants of the study received the homoeopathic complex. The atopic dermatitis was evaluated using the SCORAD index (Scoring of Atopic Dermatitis) (Appendix F) and the Children’s Dermatology Life Quality Index (CDLQI) (Appendix E). Thirty four participants who met the inclusion and exclusion criteria were recruited to participate in this pre-test – post-test single group study by means of advertisements (Appendix A) placed in and around primary schools in the Gauteng area (with relevant permission given) and in the local newspaper. Participants were also recruited via word of mouth. Once participants were accepted into the study they were allocated into the treatment group which received the homoeopathic complex containing Graphites 6cH, Histaminum 9cH, Psorinum 6cH and Sulphur 6cH. The study was completed over a four week period. The percentage of the area affected, the intensity of the symptoms, the pruritus and the loss of sleep as well as the quality of life of the participants suffering from atopic dermatitis were aspects of the condition evaluated on a weekly basis. The results for the CDLQI showed improvements in the participant’s perception of itching/ pain of the affected area, as well as their quality of sleep. These improvements were shown to have occurred gradually over the study period. There were however no statistically significant changes noted in the mental and emotional quality of life of the participants.
