Manchineel

TL0; $1/dose

If arrows dipped in the sap of local Carrouban poison apple trees; if hit by one or more, make a HT-2 roll to avoid an extra 1d toxic damage an hour after exposure. A successful Physician or Poisons roll can create a poultice to negate the effect.

On the trees themselves - with distinct grayish bark and small apple-like fruit, the notorious manchineel trees (which the Conquistan call manzanilla de la muerte, “little apples of death”). Their bark and sap is toxic, and even sheltering under one during a rainstorm can be dangerous. (HT-2 roll or take 1d-3 corrosion and 1d-3 toxic damage for every hour one was exposed to the tree.)
