Neyshabur Turquoise has been used for more than 2000 years and for this turquoise it is sometimes called "the turquoise land". Neyshabur turquoise and jewellery made from it are sold as souvenirs in Neyshabur and Mashhad resorts.
Rhubarb (Persian rivaas or rivand), a sour vegetable, grows at the foot of the eponymous Rivand Mountains (more recently, Turkified as Mount Binalud). Soft drinks made from the stems of the plant, such as "Sharbate rivaas" (in Persian:شربت ریواس) and "Khoshaabe rivaas" (in Persian:خوشاب ریواس), are sold at some Nishapur resorts as souvenirs.
