Plant description

Cardamom is a perennial herb of the ginger family, growing up to 60 cm high. Its leaves are large, green, and oval-shaped, arranged alternately. The flowers can be either white or purple, and the three-chambered pods contain seeds. These seeds, known as cardamom, are used as spice and flavoring. The genus name “Elettaria” is believed to have originated from the local name of the Malabar region in Sri Lanka. Its type is known to be  close to Ginger, Ply and Turmeric but the root lacks aroma; instead, the fragrance emanates from the small seeds and their pods. Cardamom boasts a rich history as a spice, having been introduced to Europe from India around the 2nd century BC.

Cardamom Essential Oil Properties & Uses

Around 3.5%-7% of Cardamom essential oil is obtained from the seeds by steam distillation, and is colorless to pale yellowish in color. Its primary constituents include terpinyl acetate and 1,8-cineole, known for its properties in reducing bad breath. The aroma of cardamom essential oil is characterized as bright, fresh, invigorating, spicy, and sweet. It pairs well with various essential oils, but it particularly complements strongly scented floral essential oils like Neroli and Ylang Ylang. Due to its moderate fragrance, it's advisable to add it to blends gradually to maintain a harmonious balance.

Stress Reduction

A study reported that brain tumors in mice that inhaled the fragrance of α-pinene became smaller. However, no melanoma cell growth was observed with the addition of α-pinene, indicating a potential psychological effect .1)

Anti-bacterial Effects

A study reported that α-pinene had an inhibitory effect on the growth of blue staining fungi, both when exposed to gas and when added to the culture medium2)

Anti-inflammatory Effects

It is known that the addition of lipopolysaccharide (LPS) in RAW264.7 cells induces the production of nitric oxide (NO), a substance that causes inflammation. A study reported that the production of NO was suppressed by the addition of α-pinene.3)

Anti-inflammatory Effects

A study reported that in mice with inflammation in the leg, swelling was concentration-dependently reduced in the 1,8-cineole-treated group.1)

Deodorizing Effects

A study reported that when common odorants like skatole and 3-methylbutanoic acid were stored in a sealed container with 1,8-cineole, the odorant components were significantly diminished.2)

Antimalarial Effects

A study reported that the addition of 1,8-cineole reduced the number of infected cells in malaria-infected erythrocytes. Furthermore, it was found to inhibit the intracellular growth of Plasmodium falciparum and mitigate the brain edema caused by the infection3)

Stress Reduction

A study reported that mice subjected to cold stress at 4°C (41°F) exhibited reduced elevations in blood corticosterone levels when treated with limonene. Furthermore, the same report demonstrated that limonene effectively lowered corticosterone levels in the blood of mice exposed to both physical and mental stress.1)

Memory Improvement

A study reported that when acetylcholinesterase reacts with acetylthiocholine in phosphate-buffered saline, the introduction of limonene inhibits the degradation by acetylcholinesterase. Acetylcholinesterase plays a role in the breakdown of acetylcholine, a hormone associated with memory and learning. In the same report, it was also noted that limonene suppressed memory impairment induced by scopolamine administration in rats.2)

Anti-cancer Effects

A report indicated that the consumption of limonene by breast cancer patients resulted in reduced expression of Cyclin D1, a protein crucial for cell division, within tumors.3)Furthermore, numerous other studies have also documented the anticancer properties of limonene.4)5)

Stress Reduction

A study reported that linalool treatment increased the time it took for mice to escape to a dark room when under light stress. Additionally, it reduced the number and duration of attacks on other mice in a confined room, indicating its stress-reducing effects.2) Linalool inhalation was observed to reverse gene expression alterations in the hypothalamus associated with stress response in mice.3) Numerous studies have documented the stress-reducing capabilities of linalool.4)5)6)

Anti-oxidant Effects

A study reported that the addition of linalool was found to suppress the generation of reactive oxygen species (ROS) induced by UV irradiation in human skin fibroblasts.7)
