Blood

Blood is, as it's name would suggest, a dark, sticky red liquid found most often on Blood planets. It does not impart any status effects when walked into, and has few uses other than being extracted for copious amounts of Oxygen.

Additionally, putting either Red Honeycombs or Blood Root Seeds into the Extraction Lab will produce 2 and 4 measures of Blood respectively.
