Th is plant is best knozvn as a fish poison, its usc for thïs pur- 
pose being espccially zvcll known to the Concozo and Numlaki 
Indians, who formerly inhabited the Sacramento Valley. These 
tribes mash zip the fresh plants zvith rocks and throzv this pro- 
duct, without any additional ingrediënt, into pools or sluggish 
streams. The fish are quickly intoxicated and float to the surface, 
when they are easily caught by hand or scooped out of the water 
zvith shallow sieve baskets made of small wands of zvillow. More 
of ten, however, other ingredients, such as soap root ( = Chloro- 
galum) or turkey mullein ( = Croton ) leaves, are added. These 
two plants are considered to bc much more poisonous than the 
blue curls, but the latter is preferred to the fresh leaves and 
fruit of the buckeye, zvhich are occasionally used for the same 
ptirpose. 
The Concows also especially value an infusion of the leaves as a 
head wash for the cure of feverish headachcs.
