Wow! Good find. So adrenochrome use, though probably not known by that term back then, goes all the way back to at least 1590.
FTA:
Stories describing Hungarian Countess Báthory’s vampiric tendencies, such as the tale that she bathed in the blood of virgins to retain her youth, were generally recorded years after her death, and are considered unreliable. Her story quickly became part of national folklore, and her infamy persists to this day. Some insist she inspired Bram Stoker’s Dracula (1897), though there is no evidence to support this hypothesis. Nicknames and literary epithets attributed to her include The Blood Countess and Countess Dracula. [end]
I like the way the elite-controlled wikipedia editorializes that the stories of her bloodlust are “unreliable” and there’s “no evidence that she inspired Dracula”. That’s the thing about the truth - it persists, even after 431 years. They only describe that she ‘bathed’ in the blood, so they may have managed to dilute the persistent truth.
We’ve got our work cut out for us if we’re going to undo more than 400 years of bloodthirst by people in positions of power.
