Lavender

After doing a bit of research I wondered if this might be worth as much as 50 haircuts! :) For according to Wikipedia, "During Roman times, [lavender] flowers were sold for 100 denarii per pound, which was about the same as a month's wages for a farm labourer, or fifty haircuts from the local barber. Its late Latin name was lavand?rius, from lavanda (things to be washed), from the verb lav?re (to wash). The Greeks discovered early on that lavender if crushed and treated correctly would release a relaxing fume when burned.In medieval times powdered lavender was used as a condiment."
