Active Phytochemicals
1. Eugenol (1-hydroxy-2-methoxy-4-allylbenzene
Eugenol is a naturally occurring phenolic molecule found in Tulsi. It has been used as a topical antiseptic as a counter-irritant and in dental preparations with zinc oxide for root canal sealing and pain control. Although not currently available in any FDA-approved products (including OTC), eugenol has been found to have anti-inflammatory, neuroprotective, antipyretic, antioxidant, antifungal and analgesic properties. Its exact mechanism of action is unknown, however, it has been shown to interfere with action potential conduction. There are a number of unapproved OTC products available containing eugenol that advertise its use for the treatment of toothache.
