In South Africa, 27% of adult males and 31% of adult females experience insomnia. Insomnia may lead to feelings of fatigue and sleepiness, mood disturbances, cognitive difficulties, and may exacerbate symptomatology of co-morbid diseases. Current conventional treatment for insomnia includes both psychological and drug therapies. These conventional medications potentially may lead to dependency and withdrawal symptoms. Individualised homeopathic treatment is a process in which a homeopath selects the most appropriate remedy for the treatment of a condition in accordance with the fundamental principles of homeopathy. This treatment protocol may offer safe and effective treatment for insomnia disorder, however, more research is required on the subject. The aim of this study is to determine the effect of individualised homeopathic treatment of insomnia disorder in females using detailed case studies and the Insomnia Severity Index.
