Jvara brahmástra.¹ Take of white arsenic two tolás, soak it in cow's urine for three days, and afterwards in the juice of Celsia Coromandeliana (kokasima), for one day, and then wash in cold water. Take a small quantity, the weight of a mustard, (about one-ninth of a grain), and administer within a lump of sugar in intermittent fever before the paroxysm comes on. Thus taken for three days, it cures recent and chronic fevers, ague and remittent fever. It is called Jvara brahmástra or the weapon which infallibly destroys fever.
