Hola Krystyn
This is "os" because it is referring to a "you plural = vosotros". You can see that the verb is "curar" and the form "curáis" is for the vosotros form. If we were referring to a you singular = tú, then the sentence would be:
¿ _Te__ curas las heridas con algodón? (Do you treat your wounds with cotton wool?)
However, I understand that this may be misleading if you only look at the English translation so I added a hint saying that we are referring here to a "you plural -vosotros".
I hope this helps.
