bubble_chart Modern Pharmacology

Borneol contains dextroborneol, as well as sesquiterpenes such as humulene, β-elemene, and caryophyllene, as well as triterpenoids such as oleanolic acid, alphitolic acid, asiatic pennywort herb acid, borneol alcohol, and erythrodiol. Borneol contains levo-borneol. The mechanism of borneol is a racemic mixture of borneol.

Topical application of borneol has a mild stimulating effect on sensory nerves, providing certain analgesic and mild antiseptic effects. It is rapidly absorbed through the intestinal membrane, crossing the blood-brain barrier within 5 minutes of administration, and accumulates in the brain for a long time at relatively high levels, providing preliminary experimental evidence for the resuscitation with aromatics effect of borneol. Higher concentrations (0.5%) inhibit Staphylococcus, Streptococcus, Diplococcus pneumoniae, Escherichia coli, and some pathogenic skin fungi. It has an abortifacient effect on mid- and advanced-stage pregnant mice.
