Herbs

Pathologic 2= Collected herbs play a vital part in both the mechanics of the game and the culture of the Steppe. The most important herb is twyre, but all herbs can be used to create tinctures to boost the player's immunity or to discover disease symptoms when healing the infected.

"'Twyre is pain of the Steppe (‘huung twyrat ag agyl')'

- The Kin"

Every root of twyre is different, and some may only be picked on certain days, months, or years. It is said that stalks of the herbs have name—these named ones are the most valuable. The people of the steppe believe that twyre feeds off the deeply-buried blood of the Earth and is proof of that area's pain. Some say it even brings the souls of the dead up from the Earth.

Twyre is also called "oxitocia tvirinum", the first word of which is the Greek-derived medical term 'oxytocia' (rapid childbirth) which is related to the hormone oxytocin. The name of the herb may be taken from the Russian word tvorit', which means 'to create', and the related Ukrainian word tvaryna, which means 'animal' or 'livestock'.
