How do I properly make rosehip tea??

I'm not sure how to make my tea since I just got it a couple days ago from my mom. I've read a bunch of blogs and watched yt videos about it and most of them say I have to crush/blend the rosehips. Does it do something? Like is there more benefit to it if I blend/crush it? What I've been doing so far is just letting the whole rosehip steep for 15 mins but other than that I haven't done anything special.
