yup that's what they say - "wind" supposedly because if you deliver there's a "big" opening from where the baby comes out and the "wind" goes in...affecting your joints, etc. in the long term i.e. rhumatism (not that there is ANY scienitific proof) but that's what is said. i didn't bathe in it, didn't mind the taste of it so had ginger with rice as a go between with my MIL. the "wind" factor is also why we supposedly shouldn't take a bath / shower because when you do, the "wind" will enter your body because you're so exposed and that will lead to rheumatism too later on in your life...i took a bath 3 hours after i gave birth - of course without the consent of my MIL...but hey, you need to be clean to take care of your new born, right?!?
