Would like to treat myself to a hay wrap, any suggestions

What is a hay wrap? I am assuming it is some sort of beauty treatment. Possibly not. Maybe it's some sort of ancient Swiss farmers tradition that takes place on the first full moon after the harvest?

They do turkey wraps in Zurich HB. Is it the veggie version?

I suggest you'd google for "Heubad"

hay wrap/bath is where you lie on a bed of warm, fresh hay and are covered in more of the stuff, which is preservative-free. The warmth and moistness of the hay improves circulation, while the fragrance aids relaxation.

Thank you
