This Thai tea, spiral plant-part

teathai-cuisine

I bought these, for me, nicely spiral looking dried fruits(?) in a tea-specialized shop in Bangkok in the area of the bridge leading from Phra Khanong towards On Nut (pictured below a cooked product).

I made a gentle tasting tea from these before bed time ; it was very nice for me.

What is this Thai tea, spiral plant-part?

Please share some information you find crucial about it in the answer.
