Orange - What is it?

Last Updated: 07/21/2025

About the Oil

Cold-pressed from the vibrant peels of the sweet orange fruit, orange essential oil is as sunny and cheerful as it smells. With a sweet, citrus-forward aroma, it’s one of the most beloved oils in aromatherapy. While its aroma alone uplifts and energizes, its benefits extend far deeper — offering antioxidant, antimicrobial, and emotionally balancing properties that make it a versatile staple in wellness and selfcare rituals.

 

Why You Would Use Orange Essential Oil

This oil is a go-to when you’re looking to:

  • Lift your mood and reduce feelings of stress or anxiety
  • Support skin clarity and promote antioxidant protection
  • Refresh your space with a clean, vibrant aroma
  • Ease digestive tension or discomfort when massaged onto the belly
  • Support the body’s natural immune and inflammatory response

Behind The Science (Made Simple)

Orange oil owes most of its therapeutic magic to limonene, a monoterpene that makes up over 90% of the oil. Here’s what’s going on behind the scenes:

  • Limonene interacts with olfactory receptors in the nose, sending signals to the brain’s limbic system, which helps regulate emotion and memory. This is why orange oil is so often used to reduce tension, anxiety, and low mood.
  • On a cellular level, it’s a powerful antioxidant, helping neutralize free radicals that contribute to inflammation and aging.
  • Orange essential oil also disrupts microbial membranes, giving it broad antimicrobial effects — especially valuable in cleaning and skincare.
  • The synergistic action of constituents like linalool and myrcene adds calming and soothing effects, especially in stress-related or digestive applications.

 

How and Where It Grows

Sweet orange trees (Citrus sinensis) are cultivated around the world — particularly in Brazil, the United States (Florida and California), Spain, and parts of the Mediterranean. The essential oil is typically a byproduct of the juice industry, extracted through cold expression of the peel to preserve its fragrant, volatile compounds.

 

Use in Ancient Medicine

Citrus fruits and their peels have been used in traditional medicine systems like Ayurveda and Traditional Chinese Medicine to:

  • Promote digestion and inspire appetite
  • Clear stagnant “qi” or blocked energy
  • Cleanse and uplift emotional states
  • Ease cough, congestion, or fatigue

The peel’s aromatic oils were used in both teas and topical applications for centuries.

 

Symbolism

Orange essential oil embodies joy, clarity, and abundance. It’s linked to the energy of the sun, helping us connect to warmth, confidence, and creativity. In energetic terms, it’s believed to stimulate the sacral and solar plexus chakras, where our emotional expression and vitality live.
