The in vitro trypanocidal activity of 13 medicinal plants used by local
herdsmen in Northern Nigeria for the treatment of trypanosomosis was
investigated. Forty-four different extracts prepared from the 13 plants
were screened for in vitro activity against Trypanosoma brucei brucei
. Four of the extracts showed activity against the parasite at
minimum concentration of 8.3 mg/ml of blood
