Sure. With raspberries you can use dried berries, leafs, roots. It’s a pretty versatile plant.

You can also make tea out of gummi bears too https://www.thesweetsbarn.net/product/gummy-bear-tea/86

Again: put stuff in hot water and let it soak. Strain said stuff and you have what is loosely defined as tea.

I probably wouldn’t do used radial tire tea, but if that’s what floats your boat, knock yourself out.
