Cassia essential oil is a warm, spicy oil steam-distilled from the bark, leaves and twigs of the cassia tree (Cinnamomum cassia), a close relative of cinnamon. It is prized for its strong, comforting aroma and its natural antimicrobial and antifungal qualities, which is why it turns up in aromatherapy blends, homemade cleaning sprays and diluted massage oils. Because it is potent, it should always be diluted before use on skin and kept for external use only.
What is cassia essential oil?
If you like the smell of cinnamon, cassia will feel familiar. It shares many of the same aromatic compounds and gives a deep, sweet-spicy scent that many people find grounding. Azlok's cassia essential oil is produced in India by steam distillation and ranges in colour from light to dark yellow. It is soluble in alcohol and blends beautifully with lemon, lavender, frankincense and peppermint, along with carrier oils like coconut, almond or jojoba.
Common uses
- Aromatherapy: A few drops in a diffuser fill a room with a warm, invigorating scent that many find uplifting when energy feels low.
- Natural home cleaning: Its antimicrobial reputation makes it a popular addition to DIY surface sprays and floor washes.
- Massage blends: When properly diluted in a carrier oil, it adds warmth to a relaxing massage oil.
- Insect repellent: Spicy oils like cassia are often used in homemade repellent sprays for the home.
- Soap and candle making: A small amount contributes a cosy, spicy fragrance to handmade products.
How to use it safely
Cassia is one of the stronger essential oils, so a little goes a long way. Follow these basics:
- Always dilute. Mix with a carrier oil before any skin contact. A very low dilution, around 0.5–1 percent, is sensible because cassia can irritate skin.
- Patch test first. Apply a small diluted amount to the inner forearm and wait 24 hours before wider use.
- Diffuse in moderation. One to three drops in a diffuser with good ventilation is usually enough.
- Keep it external. Do not ingest it, and keep it away from eyes and mucous membranes.
- Avoid sun exposure on areas where you have applied it, and store the bottle out of reach of children and pets.
Pregnant or breastfeeding women, and anyone with a medical condition or sensitive skin, should speak to a doctor before using cassia oil. It is a fragrance and wellness product, not a treatment for any illness.
Simple blend ideas
- Cosy diffuser blend: 1 drop cassia with 2 drops lemon for a fresh, spicy lift.
- Calming mix: 1 drop cassia with 2 drops lavender and 1 drop frankincense.
- DIY cleaning spray: A few drops in water with a splash of alcohol and a mild surfactant, shaken well before each use.
Buying and storage tips
Azlok offers cassia essential oil starting at around ₹199, with pack sizes from 100 GM up to bulk 25 KG options, which suits both hobbyists and small businesses making soaps, candles or cleaning products. Look for the botanical name Cinnamomum cassia and a clear country of origin on the label. Store the bottle tightly closed in a cool, dark place away from direct sunlight and heat. Kept well, it has a shelf life of about two years. Because it is flammable (flash point around 100 °C), keep it away from open flames.
