Latin Name
The Latin name for star anise is Illicium verum. The genus name Illicium comes from the Latin word "illicio," meaning to entice or allure. The species name "verum" means "true" or "genuine" in Latin. This classification distinguishes it from toxic Japanese star anise (Illicium anisatum) and common anise (Pimpinella anisum).
Sweet Licorice-Scented Dark Oil
Star anise oil is a dark amber-colored essential oil with a sweet licorice scent derived from the fruit of Illicium verum. The oil contains 85-90% trans-anethole, the compound responsible for its characteristic licorice-like aroma. When stored properly in dark glass containers at room temperature (20-25°C), the oil maintains a liquid state with a viscosity of 1.544-1.556 at 20°C.
The oil's aroma can be detected at dilutions as low as 0.05% due to its high concentration of aromatic compounds. In culinary applications, standard usage rates range from 0.05% to 0.1% in final products due to its potency. The essential oil is obtained through steam distillation of the dried fruits, yielding approximately 2.5-3% oil by weight.
Eases Respiratory Congestion Naturally
Anise star essential oil, when inhaled through steam or diffusion, contains anethole, a compound with documented expectorant properties. The oil can be used for steam inhalation by adding 2-3 drops to hot water.
Studies have shown that trans-anethole, the main component of star anise oil, exhibits anti-inflammatory effects. However, specific clinical evidence for respiratory benefits is limited.
Safety note: Star anise essential oil should be properly diluted before use and avoided by pregnant women, nursing mothers, and those with estrogen-sensitive conditions due to its estragole content.
Chemistry
Understanding the respiratory benefits of anise star oil begins with its chemical composition. The molecular structure contains several key compounds that define its chemical properties.
