Does anyone know what those branches are in Goblin Slayer episode 7? Does any one know what these branches are and what their purpose is (like herbal)? Is it in Japanese culture or any other culture?
NSFW (Nudity) content and manga spoilers ahead.

Those are White Birch Branches. It's also mentioned in the manga during Chapter 20.


    


I'm not sure of their exact use but according to the Wikipedia page of birches,


  fragrant twigs of silver birch are used in saunas to relax the muscles.


This seems to coincide with what is shown in the manga/anime, as it looks like it is used to relieve exhaustion and provide relaxation.
