Janey & John,
Thanks for doing some research for me. We just brought the cabinet into the basement yesterday, but ran errands all day and volunteered at the Heritage Center last evening. Left it in the car overnight due to rain. I get wintergreen for about 8 bucks for a tiny bottle,, ordered from the pharmacy. Caution: don't put wintergreen into a dispenser plastic bottle, even those with a metal point/dropper. I learned the hard way. it basically destroyed it!.
Will review all of your research & Update on results.
