The Elixir of the Wounded Heart was made out to be a rare commodity in Season 4. The only place we've ever seen someone get it from is Zelena in the Emerald City, but since that last happened, Zelena has been banished. It may have been lost in the battle between her and Dorothy. But even if it wasn't, Henry was already mostly dead when Regina cast the Dark Curse and they probably couldn't get to Oz that quickly.

Hook and Alice is more questionable since they've had ~28 years working on this. Maybe the Elixir of the Wounded Heart doesn't work on this kind of poison. We've only see it work on heartbreak and the Darkness consuming Rumple, and the latter it only worked temporarily. We don't even know if Henry's heart was poisoned.
