Ancient Egyptians used thyme for embalming. The ancient Greeks used it in their baths and burnt it as incense in their temples, believing that thyme was a source of courage. It was thought that the spread of thyme throughout Europe was thanks to the Romans, as they used it to purify their rooms and to "give an aromatic flavour to cheese and liqueurs". In the European Middle Ages, the herb was placed beneath pillows to aid sleep and ward off nightmares. In this period, women would also often give knights and warriors gifts that included thyme leaves as it was believed to bring courage to the bearer. Thyme was also used as incense and placed on coffins during funerals as it was supposed to assure passage into the next life.
Thyme is widely cultivated for its strong flavor, which is due to its content of thymol. It is best cultivated in a hot sunny location with well drained soil. It is generally planted in the spring and thereafter grows as a perennial. It can be propagated by seed, cuttings, or by dividing rooted sections of the plant. It tolerates drought well. The plants can take deep freezes and are found growing wild on mountain highlands.
