Morus, commonly known as mulberry, has been used in traditional medicine systems, particularly in East Asia, to help with sleep disorders including insomnia. Traditional Chinese Medicine (TCM) employs mulberry leaves (Morus alba) and fruits as soothing agents believed to nourish the heart and calm the spirit, which are thought to promote restful sleep. Historical texts and herbal compendia from China often list Morus among the ingredients in formulas for calming the mind and alleviating restlessness or insomnia, sometimes in combination with other herbs.

However, scientific studies directly investigating Morus species for insomnia are limited. A few preclinical studies suggest that certain compounds in Morus, such as flavonoids and alkaloids, may have sedative or anxiolytic effects in animal models. For example, some studies report that extracts from mulberry leaves or fruits can increase sleep duration or reduce anxiety-like behaviors in rodents. Despite these findings, robust clinical trials in humans are lacking, and the precise mechanisms or active constituents are not well characterized.

Therefore, the primary justification for using Morus to support or treat insomnia is based on traditional usage rather than strong scientific validation. While some preliminary pharmacological evidence exists, it is not sufficient to firmly establish efficacy or safety for this indication.
