How It Works
Saffron contains more than 150 volatile compounds, mainly terpenes, terpene alcohol, and their esters. However, the main active compound in saffron is crocin, responsible for the color and most of the pharmacological effects of the herb.
Saffron has mainly anti-inflammatory and mildly sedative properties, thanks to the action of crocin on GABA (gamma-aminobutyric acid) production. GABA is the main neurotransmitter in charge of lowering excitable activity in the central nervous system, which in turn induces sleep and lowers anxiety symptoms. At the same time, crocin lessens the effect of inflammatory processes, mainly muscle pain, and also helps reduce blood pressure.
In addition, saffron contains large amounts of carotenoids, including zeaxanthin and lycopene, which are necessary for healthy eyesight and may help relieve arthritis pains.
Saffron reduce the negative effects of insomnia due to the presence of crocin, which acts as a sedative.

Saffron does best in temperate regions, with full sun exposure.
Saffron should be planted in well-drained soil, with a pH of 6.0 - 8.0. If saffron crocus is planted in swampy or poor draining soil, it will rot.
Saffron grows best in hot and dry conditions, though it can survive winters as cold as -10°C (14°F).
It should be planted four inches (10 cm) deep, and seeds should be separated four to six inches (10 - 15 cm) away from each other.
Saffron is high susceptible to fungus contamination, so it is important to check for it regularly.

Saffron, known primarily as one of the most expensive spices in the world, has numerous characteristics that make it incredibly distinctive. Growing up to 8 to 12 inches (2030 cm), and sprouts 5 to 11 white, non-photosynthetic leaves known as cataphylls. Its flowers are sweet, fragrant smelling are typically purple, ranging from light lilac to darker mauve in shade. The flowers typically bloom in the autumn months.
Scientifically known as Crocus sativus, saffron is a member of the Iridaceae family, which contains perennial plants that have either a bulb, rhizome, or corm, including approximately 1,500 species, some of them well-known ornamental herbs, such as Irises, Crocus, an Freesia.
Varieties of Saffron
Saffron species are often regionally distributed and characteristically distinct, but most fall within the Spanish, Iranian, or Italian varieties. Among culinary connoisseurs, the saffron varieties produced in Spain are prized for their mellower flavor, while the Italian varieties are regarded as possessing a more potent aroma, and the Iranian saffron is considered the most intense. The 'Aquila' variety is regarded as the premium saffron, and it is characterized by a high safranal and crocin content.
Researchers believe its use as a food crop can be traced back to temperate regions of Greece approximately 3,500 years ago. During prehistoric times, it was used in pigments for depictions on ancient constructions. There is documented evidence of saffron being used to treat over 90 illnesses over the course of 4,000 years. In the 10th century BCE, saffron was woven into fabrics, and in 500 BCE, it began being used throughout South Asia in different foods. During the times of the Roman Empire, saffron started gaining popularity in Europe, and it subsequently spread throughout the rest of the world.
Saffron is the most expensive spice in the world. Most of the world's saffron is grown east of the Mediterranean, though small amounts are grown in every continent in the world, aside from Antarctica. Annually, about 660,000 pounds (300,000 kg) of saffron are gleaned. Iran is the top producer of saffron, accounting for over 90% of it, followed by Greece, Kashmir, and Morocco. Saffron's stamens are the most commercialized part of this plant. However, all parts of the plant are sold commercially.
Because of how expensive it is, many crooks have sold fake saffron to turn huge profits. In the 15th century, saffron counterfeiters in Germany were sentenced to death, since saffron was, and still is, more valuable than gold.
