The '''Tepary bean''' (''[[Phaseolus]] acutifolius'', [[Fabaceae]]) is native to the [[Southwestern United States|southwestern]] [[United States]] and [[Mexico]] and has been grown there by the native peoples since pre-Columbian times. It is more drought-resistant than the [[common bean]] (''Phaseolus vulgaris'') and is grown in desert and semi-desert conditions from [[Arizona]] through [[Mexico]] to [[Costa Rica]]. The water requirements are low and the crop will grow in areas where annual rainfall is less than 400 mm. It has recently been introduced to [[Africa]]n [[agriculture]].
Other names for this bean include '''Pawi''', '''Pavi''', '''Tepari''', '''Escomite''', '''Yori mui''' and '''Yori muni'''. The name ''tepary'' may derive from the [[Tohono O'odham]] phrase ''t'pawi'' or "It's a bean".
Tepary beans are cooked like other dry beans after soaking. Some Native Americans would toast the dry beans, then grind them into a meal which was mixed with water before eating.
Recent studies from the United States and Mexico suggest that [[lectin]] toxins and other compounds from tepary beans may be useful as chemotherapy for treating cancer. However, further research is needed.
