Paints made from saffron were being used for drawing 50,000 years ago. These have been found in the country that is today called Iraq. Later, people called the Sumerians used wild-growing saffron in their remedies and magical potions. Traders carried saffron for long distances before the 2nd millennium BC. Ancient Persians were growing their own type of saffron ("Crocus sativus" 'Hausknechtii') in Derbena, Isfahan, and Khorasan by the 10th century BC. Sometimes saffron threads were woven into textiles. They were given as offerings to the gods and used in dyes, perfumes, medicines, and body washes. Saffron threads were also scattered across beds and mixed into hot tea as a way of curing sad feelings. Other people were afraid that the Persians would use saffron as a drug and aphrodisiac. During his Asian campaigns, Alexander the Great used Persian saffron in his tea, rice, and baths to help heal his battle wounds. Alexander's troops copied their leader's actions and brought the habit of saffron-bathing back to Greece.
