So we all know according to this study http://www.ncbi.nlm.nih.gov/pubmed/10641130 Rosmarinic
Acid (in Rosemary) increases PGE2.
However if you look at this study http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3307200/ that details Rosmarinic
Acid content in Labiatae family plants, specifically Table 2 lists peppermint oil as having 4x the Rosmarinic
Acid content than Rosemary.
Spearmint oil does even better at 8x the content, however the menthol in Peppermint oil causes increased blood flow so most likely results in better absorption.
