This is taken from the article on the weapon that injured Guilliman, the Kinebrach AnathameL

The Apothecaries of the XVI Legion proved incapable of healing the Warmaster's wounds despite every form of advanced medical technology at their disposal, until it seemed that Horus would surely die. The Luna Wolves' notable Apothecary Vaddon examined the Primarch's wound, discovering that the fell weapon's toxins rendered even Horus' superhuman immune system powerless in the fight against them. His Larraman Cells were no longer functioning correctly, and so the open wound could not clot properly, causing Horus to bleed profusely.
