Kitzur Shulchan Aruch 50:9
If one had something caught in his throat, and he drank a drink or ate bread -- or any other enjoyable substance -- to help him swallow, he must make a bracha both before and afterwards. However if someone drank [just plain] water, not because he was thirsty, but because it would help him swallow what was stuck in his throat, or other purposes, he should make no bracha, as a person does not enjoy water unless he is drinking for his thirst.
Presumably Kitzur is saying that you'd make a "Shehakol" on apple juice if you used it to swallow a pill; so I'd figure you would make a "shehakol" on apple sauce if it was used as the carrier for a powder. No?
