Ok I'm going to quote directly from the cards here:"You can get rid of a poison counter with a ♥ (that ♥ does not also heal a damage)"
"You can get rid of a shrink counter with a ♥ (that ♥ does not also heal a damage)"
From the wording on the cards it does imply that removing a counter with a ♥ is a form of healing as it says does not also heal a damage.
Also, side note what is the rules issue with the English version? My version which is in English says:
"The Monster in Tokyo cannot use the ♥ result on the dice to heal (but can heal using cards)"
