Thraynîs

Thrayniis is a brown paste prepared from the  ayniic flea, a fairly large (1/8") flea native  to   tropical  plains  (both  tall-  and  shortgrass)  or savannas, where  it feeds  on most  mammals,  particularly  large herbivores like  cattle and antelopes.  The ayniic flea itself is quite common, but the knowledge of its preparation into thrayniis is much  less common.   Ayniic  fleas are  captured by  coating a cowhide with  a sticky  mixture which usually contains five parts honey, five  parts glue,  and one part cow urine, then stretching the coated  cowhide in  the sun on a tree near ground level.  The captured fleas are then ground into thrayniis paste with a mortar and pestle.   Thrayniis  causes paralysis;  at minimum, it has no ill effects.
