Patchouli was used to cover the smell of pot. Explanation: I graduated from IU in the late 70s.Sallyinindiana and Leahsmom--you are both too funny! I didn't know anyone used cloth diapers anymore (haven't had babies around the house for decades)--and I had to look up Ina May. If you had said "must have knowledge of dr Spock", not meaning a Vulcan, that would've been more my baby-raisin' times.
Didn't find patchouli did much for the kids, but if you slipped a little whiskey in the bottles...a totally different story. LOL

We had some patchouli plants last summer (not pot--lol). You could rub the leaves to smell that cool smell. I still like it.
