Coriander Seed Oil Elevates the Senses and Tones Digestion

Whole Coriander SeedsCoriander appears in so many different cuisines that it can be hard to determine where the plant first originated. We know by its Latin name, Coriandrum sativum, that coriander has been cultivated by humans for a long time (sativum means “cultivated” in Latin). The seeds have been found in ancient Greek and Egyptian ruins that are thousands of years old. Coriander seed essential oil  is commonly used today as a appetite stimulant, energizer, and detoxifying oil for the whole body.

An annual herb in the carrot family Apiaceae, coriander is a soft plant with feathery roundish leaves and small pale pink or white flowers that bloom in clusters called umbels. Coriander is native to Southern Europe, North Africa and Southwest Asia. As a testament to its status as an ancient food, preserved coriander seeds have been recovered from the Stone Age level of the Nahal Hemel cave system in Israel; today, coriander seeds, leaves, and even roots are widely used in cooking, especially in Indian, Southeast Asian, and Mexican dishes. In fact, the common English word for coriander leaves, cilantro, is taken from the Spanish word for the plant.

The word coriander most likely comes from the ancient Greek koriadnon. It may be related to the Greek word koris, meaning “stinkbug”, since the Greeks believed that the smell of crushed coriander seeds had a similar pungent aroma! Interestingly, modern studies have suggested that genetic factors are at the root of some people’s dislike for the smell and flavor of coriander when used as a garnish or cooking spice: a minority of people are sensitive to unsaturated aldehydes in coriander, which causes them to perceive an offputting “soapy” smell or taste in coriander leaves and seeds.

However, history attests that most people love the smell and taste of coriander: the ground seeds are used as a spice in classic Indian and Southeast Asian curries, and even added to Belgian beer during fermentation to impart a hint of citrus to the completed brew. The seeds are also used to flavor Chartreuse liqueur, and may be added to rye bread as a substitute for caraway seeds when those aren’t available.

There’s another very good reason why coriander is so popular in cuisines worldwide: coriander seed has beneficial regulatory effects on digestion, and can relieve wind and indigestion [1]. Coriander seed essential oil may be used in massages to address digestive complaints, ease muscle and joint pain [2], and act as a general detoxifier for the body [3]. A warming, uplifting oil, coriander essential oil is also inhaled to stimulate the senses and clear away mental fog; its energizing aroma can banish weakness and fatigue, and may be helpful in treating tension headaches [4]. Blend it with woody or spicy oils such as cypress, cinnamon, ginger, pine, and sandalwood for a truly memorable fragrance that leaves you feeling clearheaded and ready to tackle your day.

Star Anise Oil for Digestive Issues and Stomachache

Star Anise Seed PodsNamed for its distinctive star-shaped seed pod, star anise has been used as a cooking spice and medicine in East and Southeast Asia for hundreds of years, especially in the treatment of digestive disorders such as upset stomach and wind [1]. Star anise essential oil is clear to pale yellow with a strong licorice-like odor reminiscent of anise seed oil, although the two species are not closely related. Its familiar aroma comes from the presence of anethole, a compound with beneficial regulating properties for the digestive system [2].

The star anise (Illicium verum) is a small evergreen tree native to Southwest China and Northeast Vietnam. The genus name Illicium comes from the Latin verb illicio, meaning to entice, because star anise’s sweet-spicy flavor was believed to attract anyone who smelled it. Not surprisingly, star anise seed pods are popular in East, South and Southeast Asian cooking, especially in Vietnam, Malaysia, and Indonesia. Star anise seed pods add dimension to Chinese Five Spice, Indian garam masala and biryani rice, and Vietnamese phò noodle soup. In the West, star anise seeds are often used as a more economical alternative to anise seed for flavoring baked goods and liqueurs such as Anisette.

In traditional Chinese medicine, star anise is considered a warming and moving herb that is stimulating to the stomach, spleen, gall bladder and liver [3]. Star anise essential oil and star anise tea were used to treat ailments resulting from blockages in these systems. Star anise seeds were chewed after meals in China and Japan to sweeten the breath and aid digestion, and the tea made from the seeds was sometimes employed against rheumatism. Today, aromatherapists use star anise essential oil in massages to treat indigestion, colic and gas, rheumatism, and menstrual cramps []. Star anise oil may also be diffused and inhaled to treat congestion, persistent coughs, colds and chills, to relieve mental fatigue, and to balance the emotions [4].

Interestingly, traditional and modern medicine also cross paths in the star anise tree: star anise seed pods are the main commercial source of shikimic acid, a precursor of the drug oseltamivir (Tamiflu), which is used to treat influenza [5]. Shikimic acid is extracted from star anise seeds in a 10-stage process that takes a year to complete!

While star anise seeds are safe for human consumption, the seeds of a related species, Illicium anisatum, are toxic: native to Japan, this species contains the neurotoxic compounds anisatin, neoanisatin, and pseudoanisatin, which can also cause inflammation of the kidneys and digestive tract if the seeds are consumed [3]. Illicium anisatum seeds were once burned as a ceremonial incense in Japan, but today it is recommended to avoid using this species in any application. Always buy your star anise essential oil from a reputable vendor that lists the genus and species (Illicium verum) on the label to make sure you are getting a true, verified star anise essential oil.

Blood Orange Oil is a Unique Antioxidant Citrus Oil

Fresh blood orange halvesThe blood orange is a varietal of the classic sweet orange, Citrus sinensis; the blood orange produces an even richer oil with a scent some have called “oranger than orange”! Both the dark red pigmentation and antioxidant properties of blood orange essential oil come from the presence of anthocyanins, antioxidant pigments normally found in dark berries and other purple or red fruits such as pomegranates [1].

Blood oranges are now widely thought to be a mutation of the sweet orange. This is based on the discovery that all oranges have the gene to make anthocyanins, but only blood oranges have this gene activated [2]. Since at least the 18th century, blood oranges have been cultivated in Italy and China, and they’re now the main type of orange grown in Italy. In the U.S., both California and Texas grow blood oranges commercially. The anthocyanin pigmentation only develops when the oranges are grown in a Mediterranean climate where the nights get cold during the fall and winter months [2].

As with other citrus fruits, blood orange essential oil is extracted by cold pressing the rind of the fruit. Blood orange oil is mainly used as a mild anti-depressant and aphrodisiac [3]: its fresh, rich citrus scent elevates the mood and stabilizes the emotions, and may have a warming effect on the body.

Similar to bergamot oil in its uses and effects, the smell of blood orange oil can calm the nerves and ground the psyche; it also adds body to many citrus-based blends and perfumes. When using blood orange oil on the skin, be sure to wait 24 hours before sun exposure to avoid photosensitization [4].

Blood orange essential oil is unique among citrus oils for its concentration of anthocyanins, which otherwise don’t occur in citrus fruits. Due to its high acid content, blood orange oil can also be used as a household cleanser and antiseptic [5], but we imagine you’ll want to hoard every drop of this refreshing oil to buoy your spirits and reset your senses whenever you need a pick-me-up!
