Albizia julibrissin, commonly known as silk tree or mimosa, is traditionally used in Chinese medicine, where its flower ("He Huan Hua") and bark ("He Huan Pi") are employed for calming the mind, alleviating anxiety, and treating symptoms such as insomnia, irritability, and "restless dreams." The concept of "restless dreams" is referenced in traditional Chinese medicine (TCM) texts, where disturbed sleep with excessive dreaming is considered a sign of internal imbalance, often associated with emotional distress or "shen" (spirit) disturbance. Albizia julibrissin is described in the Ben Cao Gang Mu and later materia medica as an herb that "calms the spirit and relieves constraint," with specific mention of its use for disturbed sleep and excessive dreaming.

Regarding scientific evidence, modern pharmacological studies have identified anxiolytic and sedative-like effects in extracts of Albizia julibrissin in animal models. However, these studies do not specifically address "restless dreams" as an outcome, focusing more broadly on sleep, anxiety, and mood. No high-quality clinical trials exist that specifically evaluate its efficacy for restless dreams in humans. Thus, while its use for restless dreams is well-grounded in TCM tradition, direct scientific validation for this specific indication is limited, and the evidence rating reflects this gap.
