Objective: To evaluate the anthelmintic property of Saba senegalensis (A.DC) Pichon (Apocynaceae) (S. senegalensis) on Haemonchus contortus that is traditionally used in Burkina Faso for its gastrointestinal parasites treatment. Methods: The lyophilized aqueous decoction of leaves of S. senegalensis at concentrations of 0.10, 1.00, 3.00, 10.00 and 15.00 mg/mL was used on eggs and adult worms of Haemonchus contortus collected from gastrointestinal tract of small ruminant. Results: The LC50 on adult worms was 6.79 mg/mL and 3.25 mg/mL for the leaves of S. senegalensis and the levamisole (reference drug), respectively. Inhibition of hatching assay showed a concentration-dependent manner with an inhibition of 93.63% at the concentration of 15.00 mg/mL of S. senegalensis. Conclusions: These results indicate that the aqueous extract of S. senegalensis possesses an anthelmintic property and may justify its use in traditional medicine for the treatment of gastrointestinal parasites.
