Poisons with a '' / '' in their Effect square

[Maerimydra]

I don't understand how a poison with a ''/'' in its Effect square works. Can someone explain it to me please?

Example:

Sassone leaf residue - Effect: 2d12 hp/1 Con
Swampseer poison - Effect: 1d4 Wis/1d2 Wis and confusion 1 min
Azure lily pollen - Effect: nauseated 1 min./paralyzed 2d4 hrs

Core Rulebook entry on Effect, under the Afflictions category (poisons are a type of affliction):
Effect: This is the effect that the character suffers each time if he fails his saving throw against the affliction. Most afflictions cause ability damage or hit point damage. These effects are cumulative, but they can be cured normally. Other afflictions cause the creature to take penalties or other effects. These effects are sometimes cumulative, with the rest only affecting the creature if it failed its most recent save. Some afflictions have different effects after the first save is failed. These afflictions have an initial effect, which occurs when the first save is failed, and a secondary effect, when additional saves are failed, as noted in the text. Hit point and ability score damage caused by an affliction cannot be healed naturally while the affliction persists.

And note, for example, in the sassone leaf residue entry:
SASSONE LEAF RESIDUE
Type poison, contact; Save Fortitude DC 16
Onset 1 minute; Frequency 1/minute for 6 minutes
Initial Effect 2d12 hit point damage; Secondary Effect 1 Con damage; Cure 1 save
