A critical overview on Thymus daenensis Celak.: phytochemical and pharmacological investigations / 中西医结合学报

ABSTRACT

Thymus daenensis Celak. is an herb endemic to Iran belonging to the Lamiaceae family. Growing in many parts of Iran, the plant is extensively used in folk medicine. This review was performed to compile phytochemical and pharmacological data of T. daenensis. Databases such as PubMed, Scopus, Web of Science, ScienceDirect, Scientific Information Database, Embase, IranMedex and Google Scholar were searched for the terms "Thymus daenensis" and "Avishan-e-denaii" up to 1st January 2014. Following reported ethnopharmacological uses, various T. daenensis preparations have been investigated for antimicrobial, antioxidant, insecticidal and immunomodulatory effects in recent studies. Moreover, numerous studies have been published on the composition of the herb's essential oil, focusing either on environmental parameters or preparation methods. Due to its high concentration of thymol, the plant's essential oil possesses high antimicrobial activities on human pathogenic strains. However, comprehensive studies on the toxicity and teratogenicity as well as clinical efficacy of Thymus daenensis are missing.
