Background: Insomnia is a widespread sleep disorder where individuals experience difficulty in initiating sleep, maintaining it, or achieving restful sleep, even when the environment is conducive. This condition can significantly disrupt personal, social, and occupational well-being. It may present as short-term, temporary, or chronic, and is frequently associated with other health issues such as anxiety, depression, cardiovascular disorders, and persistent pain. Common symptoms involve fatigue, poor concentration, mood fluctuations, and reduced efficiency in daily activities. While standard treatments often include medications like Melatonin, Escitalopram, and Lopez, their outcomes and side effects can vary. Objective: The aim of this study was to evaluate the effectiveness of Coffea Cruda, a homeopathic remedy, in comparison to conventional pharmacological treatments for improving sleep quality, as measured by the Insomnia Severity Index (ISI), in adult patients. Methods: A randomized controlled trial was conducted with 30 adult participants diagnosed with insomnia. They were evenly divided into two groups: one group received Coffea Cruda, while the other was treated with standard conventional medications. Conclusion: The findings indicate that Coffea Cruda was more effective in enhancing ISI scores compared to conventional medications, suggesting it may be a promising homeopathic treatment for insomnia. Additional comprehensive studies are encouraged to support these initial outcomes.
