Cyathula, particularly Cyathula officinalis (commonly known as Chuan Niu Xi in Traditional Chinese Medicine), has a longstanding history of use in traditional Asian medicine systems. It is often prescribed to "invigorate blood," "dispel blood stasis," and "unblock channels," which, in traditional frameworks, are associated with internal bleeding, trauma, menstrual disorders, and other circulatory issues. Classical texts such as the "Shennong Bencao Jing" and later materia medica works describe Cyathula's use in formulas aimed at treating symptoms like metrorrhagia and hematuria, conditions that would today be recognized as forms of internal bleeding.

However, scientific research directly investigating Cyathula’s efficacy for treating or stopping internal bleeding is limited. Some pharmacological studies indicate anti-inflammatory and circulatory effects, but robust clinical trials on bleeding specifically are lacking. The current evidence is thus rooted primarily in tradition, with only preliminary biochemical support. As such, while Cyathula's use for internal bleeding is well-documented in traditional practice, the overall evidence rating is moderate (2/5), reflecting mainly historical precedent rather than rigorous modern validation.
