India was known to be the first major centre for it’s production and processing in the Old World. Later, it made its way to Ancient Greece and Rome where it was considered a luxury product and used for cosmetics, paints and medicine. Owing to treacherous land trade routes, it remained a rare commodity in Europe throughout the middle ages, due to which alternates had to be used, until the 15th century, when a sea route to India was discovered.
