Actually, people use nettle bouquets to beat themselves with in sauna. It has a pain relieving effect for rheumatic and nerve pain. Only younger nettles are used which are gathered in may-june. You first dip them in hot water for 1 minute, then 3 minutes cold water, then 1 minute hot again and 3 minutes cold. Then it is ready to be used for spanking in the sauna. It feels like all of your skin has an orgasm, pretty wild.
