well yes, but you won't know the strength of salicylic acid in an infusion.
16 aspirin tablets from a cheap stockist probably only costs about 20p (if that) Would you like to spend ages peeling bark off willow trees, dry it, grind up into sawdust, extract using solvents to make enough for an infusion, or would you rather just pop down to the supermarket where it is already purified and quantified per tablet LOL
