Saffron, known as the world’s most expensive spice, contains powerful compounds that provide an array of health benefits. Extracted from the delicate saffron crocus flower, saffron oil has been used for centuries to promote overall wellness. Keep reading to learn all about the origins, extraction methods, uses, benefits, risks and more of this unique golden-hued oil.
Origins and History of Saffron Oil
Often referred to as “red gold,” saffron is one of the world’s oldest and rarest spices. Derived from the purple saffron crocus (Crocus sativus), saffron has been cultivated and harvested by hand for over 3,000 years. Some of the first historical evidence of saffron cultivation dates back to the 7th century BCE in Assyria. Ancient Persians and Greeks, along with Arab, Indian and European cultures have prized saffron for medicinal uses, fragrances, cosmetics and culinary dishes for millennia.
As a precious commodity, saffron’s value rivaled that of gold and ivory in ancient times. Demand for the prized spice led Phoenicians and Arabs to establish lucrative saffron trade routes, introducing cultivation and commerce to new parts of the world. Saffron grows best in particular soil and climate conditions, making mass production difficult. Transporting the delicate threads across long distances without damage posed an additional challenge, further adding to it’s exclusivity.
Modern techniques have made commercial saffron farming more efficient without compromising quality. However, it remains amongst the world’s costliest spices by weight. Saffron oil, steam-distilled from the plant’s vivid crimson stigmas, provides concentrated essential phytochemicals with evidence-based therapeutic potential.
Saffron Flower and Stigma Details
The Crocus sativus is an autumn-blooming perennial of the Iridaceae family. Originating from Eastern Mediterranean regions, it grows across Western and Central Asia, parts of Europe and North Africa. The purple flowers feature six petals along with three vivid crimson stigmas from the carpels that make up the pistil, the female reproductive structure of the plant. These delicate, thread-like reddish stigmas connect at the style, a specialized stalk that attaches to the inferior ovary.
Flowering season lasts about two weeks. Expert farmers with generations of cultivation experience hand pick the individual stigmas daily, gently plucking each one at the peak stage of maturity when their potency is highest. Timing during harvest is crucial since stigmas quickly begin losing aromatic intensity and color after pollination occurs. The tedious harvesting method limits the quantity obtained from each flower to just three stigma strands totaling 1-3 mg of fresh saffron weight.
It requires roughly 225,000 flowers or 750,000 hand-picked strands to produce one extra pure pound of high-grade, dried saffron suitable for oil extraction. This explains why saffron is the most labor-intensive agricultural product in the world and why it commands stratospheric prices up to $5,000 or more per pound for high grades of Iranian saffron.
Extraction and Production Methods
Steam distillation is the preferred technique for extracting and concentrating saffron’s aromatic, flavorful and bioactive components into a hydrophobic essential oil. Gently heating the fresh or dried spice causes volatile oil compounds to evaporate. As hot pressurized steam passes through, it causes the key phytochemicals to be released without burning delicate saffron strands.
The vaporized extracts and steam condense and convert into a mixture that separates into distinct liquid layers. The top hydrophilic layer is floral water (hydrosol) while the concentrated hydrophobic essential compounds constitute the bottom saffron oil layer. Herbalists frequently utilize both byproducts. However, the oil contains over 50 bioactive compounds compared to just around 30 found in the co-produced floral water. The entire process must be carefully monitored by master distillers to obtain a premium quality therapeutic grade saffron oil which is always reddish-orange.
Composition and Active Ingredients
Over 150 compounds have been detected in Crocus sativus stigmas including carbohydrates, proteins, amino acids, minerals and vitamins. However, the key phytochemicals responsible for saffron’s favorable pharmacological effects are hydrophobic terpenes, terpene alcohols and apocarotenoids found concentrated in the essential oil.
Key bioactive constituents identified in saffron oil include:
● Crocin and Crocetin – These antioxidant carotenoid dicarboxylic acids are exclusive to saffron. Crocin exists as a natural trans-crocetin diester referred to as α-crocin, the main component responsible for saffron oil’s distinctive hue.
● Picrocrocin – The glycoside precursor of safranal, it gives saffron it’s characteristic bitter flavor. Highly unstable, it rapidly degrades to yield safranal when dried, during storage or steam distilled.
● Safranal – Formed by picrocrocin hydrolysis via drying/heating/extraction, the monoterpene aldehyde is the major aroma-defining component of saffron oil. Structurally similar to curcumin, it provides many pharmacological actions.
● Kaempferol – This common dietary flavonol exhibits strong antioxidant, anti-inflammatory, neuroprotective, cardioprotective, anti-cancer and immune boosting effects.
● Zeaxanthin – Rare xanthophyll isomer and provitamin A carotenoid closely related to lutein with additional health promoting activities as an antioxidant.
Saffron oil’s broad spectrum bioactivity results from distinct synergistic and additive interactions between it’s complex mixture of volatile lipophilic phytochemicals, mainly crocin esters, safranal and other potent terpenoid constituents. Even minor oil components likely contribute substantially to it’s high value therapeutic versatility.
Uses and Applications
