Is there a rule for poisoning a healing potion?

If not, how would you handle it? The poison inflicts both damage and the 'poisoned' condition on a failed con save when ingested.

First, which poison was added?

If you meddle with an health potion, it stand to reason it doesn't work anymore.

There's no hard rule, so I would just have both effects happen. You heal from the potion, then make the Con save for damage and condition.

To make things more interesting, I would probably use the rules for mixing potions.
