Cassia Oil – A Warm, Potent Essential Oil from Vietnam
Cassia oil is a powerful essential oil renowned for its warm, spicy fragrance and therapeutic richness. Extracted from the bark of the Cinnamomum cassia tree, this oil has long been used in traditional medicine, flavoring, and aromatherapy. It combines a distinctive aroma with exceptional natural benefits, making it a prized extract in both health and wellness industries.

What Is Cassia Oil?
Derived from the bark of Cinnamomum cassia—also known as C. aromaticum or Laurus cassia—this oil belongs to the Lauraceae family. Often referred to as Chinese cinnamon or false cinnamon, Cassia is different from true cinnamon (C. verum), though their scents are similar. The essential oil is prized for its high potency and characteristic aroma, rooted in its major compound: cinnamic aldehyde.

Botanical Description and Origin
The Cassia tree is a tall, evergreen species that can reach heights of up to 20 meters. Its leaves are thick and leathery, while its small white blossoms eventually give way to berry-like fruits. The bark of this tree is what yields the familiar spice used in global cuisine and the essential oil used in various health and beauty products.
Cassia trees flourish in the diverse climate of Vietnam, particularly in regions known for their rich biodiversity. The country’s natural conditions support the cultivation of high-quality Cassia, which forms the foundation of Dien Bien Agri’s premium essential oil offering.
Extraction Process
The essential oil is obtained through steam distillation of the bark. This gentle yet effective process preserves the natural compounds, producing a pure and concentrated essential oil that retains its aromatic and therapeutic properties.
