of the Chinese Qinghaosu, an extract of Artemisia annua L. (Asteraceae), whose powerful antimalarial action ultimately was explained by oxidative activity ( Hien and White 1993; Klayman 1993; Meshnick 1994).
These investigations of in vitro antiplasmodial activity were conducted in the
laboratories of Dr. John Eaton, University of Minnesota Medical School.

Our position is supported by our medicinal plant inventory, which is more
comprehensive of local flora than our corollary catalogues for economic plants and
foods and which subsumes plants from those other categories. A second point is that
all the criteria that Hausa use to judge the suitability of plants for food are influenced
by long-term experience with botanicals used in medicinal preparations. But food
plants-even those drawn from among medicinals -- are appraised for qualities of
satiety and taste and only casually understood with reference to health value. For
this reason, while knowledge of medicinal plants guides the selection of foods, the
opposite is not true: knowledge of a food will not inform its medicinal use because
whereas texture, taste, and even toxicity are all integral to food selection, these
qualities are subordinated to their medicinal properties ( Etkin and Ross 1994:95-96).
See Etkin ( 1997) for discussion of how and why particular foods have again
captured the interest of biomedicine.
The scope and locus of our study made it impossible to include any clinical
examination or to secure blood samples for parasite analysis. In view of that, conclusions regarding the prevalence and severity of malaria infection are drawn from reports of the Nigerian Ministry of Health, the WHO Malaria Research Center in Kano,
staff of the district hospital and dispensary, published studies of malaria epidemiology in northern Nigeria (e.g., Abudu 1983; Ayeni et al. 1987; Schram 1971; Stock 1983), and, for 1987-1988, the village and hospital epidemiological surveys.
Heavily populated and intensively farmed for generations, the region in which
Hurumi is located (the Kano Close-Settled Zone) is actually home to no plants that
are, technically, wild. But the deliberate management of noncultivated species on
farm borders and public lands and those not removed during the weeding of farms
properly evokes the term "semi-wild."
