Cnidium (Cnidium monnieri), known as "She Chuang Zi" in Traditional Chinese Medicine (TCM), has a long history of use in Asian herbal medicine, especially in China. The seeds and extracts of Cnidium are primarily known for their application in skin conditions, sexual health, and as a topical agent for various dermatological issues. In the context of bruises and their healing, Cnidium is traditionally used to invigorate blood circulation, disperse blood stasis, and reduce swelling and pain. These actions are thought in TCM to support the healing of bruises and other traumatic injuries.

Classical Chinese medical texts, such as the "Shennong Bencao Jing" and subsequent materia medica, mention Cnidium as an agent to treat skin disorders and trauma. In traditional practice, it is often included in herbal formulas applied topically or taken internally for trauma, bruises, and contusions, often in combination with other blood-invigorating herbs.

However, modern scientific studies specifically evaluating Cnidium for bruise healing are limited. While some pharmacological investigations suggest that Cnidium contains coumarins and other compounds with anti-inflammatory and antimicrobial properties, these findings do not directly validate its efficacy for bruises in clinical settings. Thus, its use for bruises is primarily justified by tradition, with limited but supportive ethnobotanical and pharmacological evidence.
