Medicinal plants and phytotherapy in Iran: Glorious history, current status and future prospects

Abstract

This study is an endeavour to analyse the status of medicinal plants research in Iran. Because of its exceptional phytogeography, Iran has a unique and diverse flora. It is estimated that, 8167 species of vascular plants are present in Iran of which about 2075 have medicinal importance. Situated at the heart of the Silk Road, Iran enjoys a mix of cultures providing a rich backbone for the development of traditional herbal medicine practices. Notwithstanding the brilliant history in traditional medicine and success of investigation to produce herbal medicines, attempts in recent decades, face many challenges. Many text and paper about these concerns were never translated in English. Strong need was felt to record such data of medicinal plants of Iran, their conservation status and related information. The scattered literature over medicinal plants of Iran were collected, analysed and presented in this review, highlighting not only their therapeutic potential but also concerns about product authenticity, quality, safety and efficacy. This will provide ways for future scientific research in this area. Awareness of critical issues in traditional medicinal herbs can play a pivotal role in the discovery and development of plant based drugs and to sustain consumer confidence.
