 "The following chemical races based on essential oil composition, occur in North America: Type 1 - high in pulegone, isomenthone and menthone. Type 2 - high in linalool, cis-ocimene and trans-ocimene. Type 3 - high in cis-isopulegone and trans-isopulegone. Type 4 - high in cis- and trans-ocimene and in 1,8-cineol. These four chemotypes are not correlated with any of the morphological variations." \\ "The following chemical races based on essential oil composition, occur in North America: Type 1 - high in pulegone, isomenthone and menthone.

 century production was dominated by Japan, providing around 70% of global requirements from an estimated annual  production of around 800 tons of arvensis oil, with the remaining demand supplied by China. Brazil then took over the position of dominant supplier, with annual production reaching 5,000 tons in the mid 1960’s. Extreme price and supply volatility resulted in the collapse of the Brazilian production sector and the re-entry of China as the major supplier during the 1980’s and the first half of the 1990’s.

 "The majority of (-)-menthol is obtained by freezing the oil of Mentha arvensis to crystallize the menthol present. This "natural" menthol is then physically separated by centrifuging the supernatant liquid (called dementholized cornmint oil) away from the menthol crystals. Any residual impurities are due to traces of Mentha arvensis oil, and these often impart a slight peppermint aroma to the menthol crystals." \\ "The majority of (-)-menthol is obtained by freezing the oil of Mentha arvensis to crystallize the menthol present.
