Laser, láseris, n. gen. Plin. A gumme or iuice issuing out of anhearbe called Laserpitium. Some hauc taken it to be that which Apothecaries call Benzwine, but there be great arguments to the contrarie. I take the orst kind of Laser, which is of Media, to be our Asafœtida, and that of long time we haue had none of the best and true Laser, out of the prouince of Cyrenæ.
