Zyklin B is poison.



Antonym of poison is antidote. Or nectar, or something beneficial...Is there a possible antonyms for the gas zyklon B?
If you mean a synonym repeating Zyklon B should not be a problem as that was the trade name, but the active ingredient was hydrogen cyanide (HCN).

An antonym would be the opposite. I don't think you can have an opposite for a name, but you could use adjectives such as harmless, safe, beneficial (opposites to the idea of dangerous/poisonous).

Hope this helps.
