What is Gardenia Essential Oil?

Gardenia essential oil is an extract from the flower of gardenia plants, which are part of the Rubiaceae family. There are over 200 species of gardenia plants, but the most common ones used for essential oil are Gardenia jasminoides (also known as common gardenia or Cape jasmine) and Gardenia augusta (Madagascar gardenia).

To make gardenia essential oil, solvent extraction is commonly used. The delicate white flowers are picked and soaked in a solvent like hexane or ethanol to extract the aromatic compounds. The solvent is then evaporated, leaving behind the concentrated oil. Another method is enfleurage, where the flowers are placed on solid fat to absorb the fragrance, then the fat is treated with alcohol to isolate the essential oil.

Some key therapeutic properties and uses of gardenia essential oil include:

Anti-inflammatory – Helps reduce inflammation and swelling
Antioxidant – Neutralizes free radicals that can cause cell damage
Sedative – Induces relaxation and sleep
Aromatherapy – Uplifts mood and reduces anxiety

The oil has a very intense, sweet, floral aroma reminiscent of the gardenia flower. It’s used in perfumes, cosmetics, aromatherapy, and natural remedies.

Origins and History

The gardenia plant is native to the tropical and subtropical regions of Africa, Asia, and Oceania. Some popular species include Gardenia augusta which is native to China and Gardenia jasminoides which originated in Asia. Gardenias have a long history of use in traditional Chinese medicine as well as Ayurvedic medicine practices in India. The fragrant white flowers have been used for centuries for their medicinal benefits as well as their lovely scent (1).

Extraction Methods

Gardenia essential oil is extracted primarily through steam distillation. The process involves passing steam through crushed gardenia blossoms to evaporate the volatile aromatic compounds. The steam contains the essential oil, which then condenses and separates from the water. Steam distillation is useful for delicate materials like flowers and helps protect the aromatic compounds from damage.

Solvent extraction is another method used to obtain gardenia oil. Organic solvents like hexane are used to extract the aromatic compounds from the gardenia blossoms. The solvent is then evaporated, leaving behind the concentrated oil. Solvent extraction leads to higher yields of oil but can negatively impact the aroma profile.

Key factors in gardenia oil extraction include the freshness of the blossoms, the equipment and solvents used, distillation time and temperatures, and proper storage of the finished oil. Proper extraction helps maximize the concentrations of desired aromatic compounds like linalool, methyl benzoate, and crocin

Chemical Composition

The main chemical constituents found in gardenia essential oil can vary greatly depending on the specific species and region where it is produced. Some key components include:

Linalool (34.7%), α-farnesene (10.2%), α-terpineol (6.3%), geraniol (5.8%) and cembrene A (5.8%) were the main components of the essential oil from Gardenia jasminoides extracted in China.

In a study on Gardenia jasminoides from Yunnan, China, the main aroma components were α-farnesene (32.45%), cis-3-hexenyl tiglate (8.02%), linalool (6.56%) α-terpineol (2.40%), tau-cadinol (2.40%), geraniol (1.93%) and limonene (1.49%) [2].

Research also shows variation between different Gardenia species. The essential oil of Gardenia augusta contains mostly fatty acids and acids, while Gardenia jasminoides has a higher percentage of terpenes like linalool [3].

Benefits and Uses

Gardenia essential oil is highly prized for its luxurious floral fragrance and therapeutic benefits. Some of the key benefits and uses of gardenia oil include:

Skin Health: According to research, gardenia oil contains antioxidant and anti-inflammatory properties that can help promote smooth, glowing skin (Draxe). The oil has been traditionally used to soothe and rejuvenate the skin. It is often added to skincare products like creams and lotions.

Aromatherapy: The sweet, floral scent of gardenia oil is believed to have uplifting and relaxing effects. In aromatherapy, it is often used to ease anxiety, stress, and depression (Nature In Bottle). Diffusing gardenia oil or inhaling it directly can provide these soothing emotional benefits.

Hair Health: Some natural health proponents suggest that gardenia oil may nourish hair and enhance shine when applied topically. However, more research is still needed on the effects of gardenia on hair.

When using gardenia oil topically or in aromatherapy, dilution with a carrier oil is recommended to avoid skin irritation. Those with sensitive skin should do a patch test before wider use. As with any essential oil, gardenia should not be ingested without proper supervision. It’s best to consult your doctor before using gardenia oil if pregnant, nursing, or taking medications.

Comparison to Other Floral Oils

Gardenia essential oil is often compared to other popular floral oils like rose, jasmine, neroli, and ylang ylang. While it shares sweet, floral notes with these oils, gardenia has its own unique aroma profile.

Compared to rose oil, gardenia is less powdery and sharp. It has a warmer, creamier scent that is slightly fruity. Gardenia is considered more exotic than traditional rose. Jasmine oil is more intensely floral than gardenia. It has a richer, headier, and more romantic aroma. Gardenia is softer, sweeter, and more mysterious.

Neroli and ylang ylang oils have hints of gardenia’s fragrance, but are distinctly different. Neroli from orange blossoms is citrusy, light, and refreshing. Ylang ylang is intensely sweet and spicy. While gardenia contains subtle spicy undertones, its dominant scent is smooth, creamy, and sensual.

In terms of availability, gardenia oil is considered rare and can be quite expensive. It is not as readily available as rose or jasmine oils. Going rate for gardenia is around $70-90 for 5mL, compared to $40-60 for the same amount of rose otto. However, gardenia oil is highly prized for its exquisite aroma and powerful emotional benefits.

Buying and Storage

When buying gardenia essential oil, it’s important to look for 100% pure and natural oils. Adulterated oils may be diluted with carrier oils or contain synthetic ingredients. According to Essential Oils Company https://www.essentialoilscompany.com/products/gardenia-absolute, pure gardenia oil should have an intense, sweet, floral aroma. It’s also one of the more expensive essential oils due to the large quantity of flowers needed to produce a small amount of oil.

Proper storage is critical to maintain the integrity and shelf life of gardenia essential oil. Essential oils are highly concentrated and can degrade when exposed to light, air, and fluctuations in temperature. According to the article How to Store Essential Oils, essential oils should be stored in dark glass bottles and kept away from heat, light, and oxygen. Refrigeration can help extend the shelf life of gardenia oil and other floral absolutes up to 1-2 years when stored properly.
