Phytochemical Profiling and Therapeutic Potential of Thyme ( spp.): A Medicinal Herb.

Thymol is a phenol monoterpene that is naturally derived from cymene and is an isomer of carvacrol. It constitutes a significant portion (10%-64%) of the essential oils found in thyme ( L., Lamiaceae), a medicinal plant renowned for its therapeutic properties. Wild thyme is native to the Mediterranean region and has been used in cooking and medicine for a long time. In contemporary contexts, both thymol and thyme offer diverse functional applications in the pharmaceutical, food, and cosmetic industries. Thymol has attracted scientific interest for its potential therapeutic applications in pharmaceuticals and nutraceuticals. Studies have explored its efficacy in treating respiratory, nervous, and cardiovascular disorders, highlighting its promising role in diverse therapeutic interventions. Additionally, this compound demonstrates antimicrobial, antioxidant, anticarcinogenic, anti-inflammatory, and antispasmodic properties. It also shows potential as a growth enhancer and has immunomodulatory properties as well. Other discussed aspects include thymol toxicity, bioavailability, metabolism, and distribution in animals and humans. This review summarizes the most significant data regarding the beneficial effects of thyme bioactive compounds and their applications as a food preservative while taking into account the thyme plant extract and its essential oil.
