As an Element, Poison covers not only the usual Poison Status, but also Stone (as well as the instant KO Spell BANE). Your own Poison Spells are all instant kills, but many Monsters resist Poison. TIAMAT is notable because she has a Poison weakness (one of only two creatures in the game with one, in fact). Due to a bug in the NES game, most Poison- or Stone-inflicting standard attacks are not actually Poison elemental (they instead use the Element of any weaknesses the Monster has).
Causes the target to lose 2 hit points at the end of each turn.
Cured by Item
PURE Potion
A Poisoned character takes 1 point of damage per step taken outside of combat, and a small amount of damage at the end of each combat round. The map damage cannot kill the character, but the damage taken during combat can. Poison does not wear off at the end of combat. It can be cured with the PURE or CUR4 Spells or with a PURE Potion.
As an Element, Poison covers not only the usual Poison Status, but also Stone (as well as the instant KO Spell Poison). The main threat from Poison, however, comes from early-game Monsters that inflict it with their normal attacks. Poison deals significant damage in combat, and will doom a character if you have no Antidotes (or Esuna Spells) on hand. Your own Poison Spells are all instant kills, but many Monsters resist Poison. Tiamat is notable because she has a Poison weakness (one of only two creatures in the game with one, in fact).

Poison is an interesting Element, since you won't actually get the Scourge Spell so you can use it until pretty far into the game. Very few Monsters are weak against Poison, consisting mostly of Thunder-elemental bosses and stone creatures. It's a fun Spell to have leveled, but not at all important.

Even more so than Darkness, Poison is really only a problem because it halts progress if a Character hasn't been cured by the end of combat. A few damage per round of combat isn't a problem at any stage of the game, and while the 1 damage per step of walking can add up, Esuna 1 is enough to cure this Status outside of combat. You'll need Esuna 2 to cure it in combat, or to cure the whole party of Poison outside of combat, though.

Venom is very similar to Poison, only temporary. It is extremely easy to shake off, and often the effect ends before dealing even a single point of damage. Like Poison, the damage from Venom is minor and can be ignored for most of the game. This is one Status Ailment you will not likely have to worry about. If you do want to cure it, though, Basuna 1 can do so.

Confusingly, Poison is both an Element and a status in this game. That said, aside from the Monster Ability Acid Rain, all Poison-Elemental Abilities inflict Poison as well, so the difference is mostly elementary.
Nonetheless, the damage dealt by Poison-Elemental Abilities is significant even aside from the Status effect. Most of the Monsters that have a weakness to Poison are human, while the ones that are immune tend to be undead.
Unfortunately, a Poison weakness becomes less and less relevant as the game progresses because of the availability of tier-3 Elemental (and better) Spells. They deal more damage to neutral targets than your best Poison Spell (Bio) does against a Poison weakness.

Poison deals increasing damage based on Stamina at set intervals during combat. Each interval adds the initial damage on top of the previous interval to a maximum of 8× the initial damage.
Characters also take 1/32 of their max HP in damage per step outside of combat, but cannot die as a result.
