Aim: Uterine leiomyomas are the most common benign uterine neoplasms associated with significant morbidity. Herbal formulas capable of restoring yin-yang balance by dispersing blood stasis may be useful for managing fibroid symptoms. Materials and Methods: In this study, the antitumor properties of three herbs viz., Trogopterus xanthipes Milen-Edwards, Paeonia lactiflora Pallas, and Ulmus davidiana Planch, were evaluated in nude mice injected intravenously with human malignant myomas. Tumour fragments were xenografted subcutaneously through a flank incision in female mice. The mice entered the study for 8 weeks when their tumors reached the threshold volume (260 mm3). The mice were randomly allocated to receive subcutaneous injections of normal saline (group 1; negative control), P. lactiflora Pallas (group 2), U. davidiana Planch (group 3), T. xanthipes Milen-Edwards (group 4), and intravenous injections of paclitaxel (group 5; positive control). The weight and tumor volume were measured, followed by histopathology. Results: A few cases of abdominal distention and death were observed in the negative control group. Furthermore, a considerable enlargement of the liver and spleen was observed in the negative control group at autopsy with a gradual increase in body weight during the experiment. The mean tumor volume which increased in negative control mice reduced in mice treated with herbal remedies or paclitaxel from day 14 onwards (p
