Stop unstoppable blood with dried human blood
To stop blood that flows unstoppably.
Take human blood, either from a vein-cutter or from any other source, in whatever way it may happen, and throw it into a wide-mouthed vessel.
Dry it in the sun, and on the first day you will find a watery part floating on top.
This must be thrown out, and the rest made dry; and at the time of need plaster it on and bind it.
For it will stand, even if the flow is hard to check.
Greek
2.9 Πρὸς αἷμα δυσκατασχέτως ῥέον Λαβὼν ἀνθρώπειον αἷμα εἴτε ἀπὸ φλεβοτόμου εἴτε ἐξ ἄλλου του οἵου δήποτε <ἂν> τύχῃ τρόπου καὶ βαλὼν εἰς ἄγγος πλατύστομον, ξήραινε ἐν ἡλίῳ καὶ ἐν τῇ πρώτῃ ἡμέρᾳ εὑρήσεις ἐπιπολάζον ὑδατῶδες· τοῦτο χρὴ ἐκβάλλειν ξηρόν τε ποιεῖν τὸ λοιπόν, κἀπὶ τῆς χρείας κατάπλασον <καὶ> ἐπίδησον· σταθήσεται γάρ, εἰ κἂν δυσκατάσχετον ᾖ.
