Researchers at Islamic Azad University undertook an ethnobotanical and ethnopharmacological survey of Hezar Mountain (4465 m), the highest peak in the central region of Kernan Province and a rich, though endangered, plant ecosystem.
Working with 75 local informants, the team recorded traditional uses of 92 species in the treatment of several ailments, the most common of which were digestive disorders of the gastrointestinal tract, renal and genital disorders, respiratory tract system disorders, and heart-blood circulatory system disorders.
Among the most commonly used medicinal plants were Levisticum officinale, Artemisia persica, Thymus carmanicus, and Ziziphora clinopodioides. Poultices and extracts from Arnebia euchroma are used for their antibacterial, antifungal and anti-inflammatory properties, and derivatives have shown anti-HIV activity and anticancer properties. The authors report that “due to its medicinal uses, the species is being harve[s]ted indiscriminately from the wild both for domestic and Pharmaceutical purposes. This has resulted in A. euchroma [being] critically endangered[,] the status and its listing in the species prioritized for conservation in this region.”
The authors note several other threats to the medicinal plants of this region:
“In recent years, aridity and low precipitation have damaged the vegetation of plants in Hezar. In addition, overgrazing impact is increasingly threatening the fragile medicinal plants in this mountain.
“Some rare species such as Levisticum officinale, Thymus carmanicus, Arnebia euchroma, Dracocephalum polychaetum and Dorema ammoniacum have been threatened as herbalists and traders hire the local people for gathering these species due to the economic purposes. Many of these plants are potentially endangered and vulnerable taxa. Since the alpine plants grow very slowly, they cannot quickly re-grow leaves or flowers that are lost. Harvesting of roots, bulbs, seeds and flowers, which are essential to the survival of the plants, often lead to vanish this species. In addition, local people sometimes sell these medicinal plants in the local market for their livelihood. So, the domestication of these plants is a need for conservation.
“Lately, a Manganese purification factory has been established in 30 Km of NW of Hezar Mountain, so that the air pollution and soil toxicity are inevitable in this region. It is a direct threat to flora and fauna in the study area.”
