Interaction Details
Aspirin, Caffeine, Phenacetin, Propoxyphene is classified as belonging to the following category: Cns Depressants
Theoretically, spearmint might alter the sedative effects of CNS depressants.
Animal research suggests that (-)-carvone, a major constituent of spearmint, has sedative effects. However, in humans, chewing spearmint-flavored gum induced arousal effects.

Interaction Details
Aspirin, Caffeine, Phenacetin, Propoxyphene is classified as belonging to the following category: Hepatotoxic Drugs
Theoretically, high doses of spearmint might increase the risk of liver damage when taken with hepatotoxic drugs.
Animal research suggests that drinking spearmint tea for 30 days can increase markers of liver damage, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and cause liver degeneration and necrosis, in a dose-dependent manner. This effect has not been reported in humans.
