Brighten Your Day With Cassia Essential Oil

What does Autumn smell like to you? For me, it’s none other than… Cassia.

What does Autumn smell like to you? Living in the midwest, we are blessed to be surrounded by forests that take the opportunity of autumn to glamorize themselves with brilliant colors. Whiffs of spicy and earthy aromas fill the air.

I love using essential oils to usher in the smell of Autumn in my home. One of my favorite oils to use is Cassia. The Cinnamomum cassia plant is a close relative to cinnamon and smells similar to it. I love using Cassia Essential Oil to make my own candles and all things associated with fall.

What I Love About This Oil

I love this oil’s seasonal aroma. I love that while it smells great, it is also great for cleaning and keeping the bugs away!

Uses and Benefits of Cassia Essential Oil

Promotes Circulation 

Cassia Essential Oil creates warmth when applied topically and boosts circulation according to this study1. It can soothe muscle pain caused by weak blood circulation. Coupled with its anti-inflammatory effects as suggested by this study2, Cassia may be used to naturally ease bodily discomforts. Although Cassia’s benefits are great, please follow our dilution guide as it is an essential oil that is skin irritating.

Supports Women’s Wellness 

Because of its properties mentioned above, this essential oil may help ease soothe muscle tightness and headaches associated with menstruation. It also helps soothe other PMS symptoms like nausea and drowsiness which be further explained below.


Besides being reminiscent of fall, Cassia’s bright aroma acts as an antidepressant as per this study3, and brings about warm feelings. It’s very stimulating and may make you more alert. I love using Cassia Essential Oil in these recipes.


Cassia, like its close relative Cinnamon Essential Oil, is a great cleaner. One study4 says it has anti-microbial properties and another suggests it has anti-viral effects5. It’s a great one to use in a DIY cleaner or room spray when colds and sickness have been going through the house. 

Aids Digestion

The Cinnamomum cassia plant is popular in traditional Chinese medicine to help relieve gas, nervous stomach, and discomfort. It is effective in inhibiting the growth of bacteria, as mentioned above, therefore some may find it helpful in easing diarrhea.

Moreover, Cassia Essential Oil is great to have when nausea hits as it helps reduce retching and prevents vomiting according to this study6

Boosts Immunity

Because of the above-mentioned benefits of Cassia Essential Oil, this oil can be used to support immunity especially when seasonal threats are lingering around.

What This Oil Blends Well With

This oil is a close relative of Cinnamon Essential Oil and can often be used as a replacement for Cinnamon Essential Oil. Although, Cassia is considered to have a sweeter aroma than Cinnamon Essential Oil. 

This oil blends well with Cedarwood (Himalayan), Clove, Frankincense, Lavender, Lemon, Wild Orange, and Ylang-ylang Essential Oils.

Science and Constituents

Cassia’s main chemical constituent is Cinnamaldehyde. You probably can see the word “cinnamon” in there, giving its distinct cinnamon smell. 


It is antibacterial, anti-fungal, anti-inflammatory, antioxidant, antitumoral, neuroprotective, and immunomodulatory giving this oil amazing benefits.
