interesting, thx for sharing
1 year ago I've bought 0,5 kg of natural menthol and the country of origin is India and was produced from wild mint (Mentha arvensis)
last year I obtained slightly less than 10 ml of oil by steam distillation of slightly more than 1 kg of dried mint herb (Mentha piperita) from my
garden and similar amount is awaiting me to process it this year (when I start to heat my house with wood stove)
