I found some recipes for bath teas and wondered if you can get dried rose petals somewhere (probably a dumb question) or, if I dry my own, how long does it take for them to dry enough to be crumbled and added to a tea? Do you get most of the herbal stuff just at the grocery store or a natural foods store? I feel foolish asking, but didn't know if it made a difference where you purchased from? I have a food coop in my area and you can buy a lot of these things in bulk-that's why I ask. How much do you typically put in one of the bags???? Thanks Tracey
