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 is Cassia. The Cinnamomum cassia plant is closely related to cinnamon and smells similar. I love using Cassia Essential Oil to make candles and anything associated with fall.

Uses and Benefits of Cassia Essential Oil

Promotes Circulation 

According to this study1, Cassia Essential Oil creates warmth when applied topically and boosts circulation. 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.

Supports Women’s Wellness 

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


Like its close relative, Cinnamon Essential Oil, Cassia is a great cleaner. One study4 says it has antimicrobial properties, and another suggests it has antiviral effects5. It’s great to use as 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. As mentioned above, it is effective in inhibiting the growth of bacteria, so some may find it helpful in easing diarrhea.

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

Boosts Immunity

Because of the benefits mentioned above, Cassia Essential Oil can support immunity, especially when seasonal threats are lingering.

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 It. However, 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


Cinnamaldehyde occurs naturally and gives cinnamon its flavor and odor. This pale yellow, viscous liquid appears in the bark of cinnamon trees and other species of Cinnamomum. Cinnamaldehyde’s most obvious application is flavoring chewing gum, ice cream, candy, e-liquid, and beverages. It is also used in some perfumes with natural, sweet, or fruity scents. Cinnamaldehyde has been tested as a safe and effective insecticide against mosquito larvae. It also has antibacterial and antifungal properties. Moreover, it has some miscellaneous uses, such as being a corrosion inhibitor for steel and other alloys.


Ortho-Methoxycinnamaldehyde is a natural compound of Cinnamomum cassia with antitumor activity. It is commercially and industrially applied as a flavor and fragrance agent.

Cinnamyl Acetate

Cinnamyl acetate naturally occurs in plants and has a sweet floral-fruity fragrance. It is used in cosmetics, some toiletries, and non-cosmetic products, such as detergents.

What Earthies Are Saying About This Oil

Cassia Essential Oil from Malagassi (Northern Vietnam)

Simply Earth proudly sources its Cassia Essential Oil from the renowned Malagassi Farm in the high mountains of Northern Vietnam. Known as Vietnamese cinnamon, Cassia (Cinnamomum cassia) is diligently cultivated and nurtured by ethnic minority farmers, who have seen tremendous growth in Cassia plantations in recent years. This rise has significantly bolstered the local economy and improved the livelihoods of indigenous families. From March to September, the harvesting season aligns perfectly with the abundant sunlight for drying the bark. After three years of careful nurturing in nurseries, the cassia trees are transplanted to mountain slopes, where they begin productive yields by six years old. However, Malagassi farmers often allow the trees to reach full maturity to ensure superior quality. This prized Cassia Essential Oil, exclusive to Vietnam and a small region in southern China, owes its uniqueness to the area’s specific climate and soil conditions. Extracted through a precise steam distillation process refined over 25 years, the meticulous care taken from start to finish guarantees the highest quality essential oil.
