Safety and hemostatic effect of Achillea millefolium L. in localized bleeding.

BACKGROUND AND AIM: This study aims to demonstrate the hemostatic effect of the hydroalcoholic extract of Achillea millefolium L. in localized bleeding and to assess the safety of its topical application on rat liver.

MATERIALS AND

METHODS

The aerial parts of A. millefolium were macerated in methanol for two days. Twelve female Wistar rats, weighing 120-220 g, underwent anesthesia and laparotomy. The liver was exposed, and two incisions were made to induce bleeding. One incision was treated with a sponge soaked in A. millefolium extract, while the other served as a control. The animals were divided into two groups: in one, A. millefolium (150 mg/kg) was applied to the first incision, and in the other, to the second incision. Liver biopsies were collected after 4, 6, and 8 weeks.

RESULTS

Application of A. millefolium to liver incisions, whether first or second, significantly reduced bleeding time (by 36.1% and 31.9%, respectively). Histopathological analysis showed no signs of toxicity or hepatic damage after 4, 6, and 8 weeks in the female rats.

CONCLUSION

The study confirms the hemostatic effect of the hydroalcoholic extract of A. millefolium in localized bleeding and establishes its safety for topical use.
