The cassia plant comes from China where it has been used for thousands of years in herbal medicine. It is closely related to the cinnamon tree, however, it is not as expensive as Cinnamon and for that reason it is usually sold as cinnamon spice in grocery stores. It is commonly made from twigs, bark, and leaves from the tree. Because the properties of cassia are to support emotional and physical well-being, it can have many different applications.
A recent study released in 2009 found that cassia cinnamon extracts had surprising effects in both animal and human subjects with type 2 diabetes. They specifically found that serum glucose levels along with their cholesterol, triglycerides, and LDL cholesterol levels all decreased during the study when ingesting cassia essential oil.
A common use of cassia oil when having stomach problems is to drink a few drops with warm water. This has been found to calm the stomach and help with digestion. It is also frequently diffused around offices and living areas to help with colds, fevers and even the flu. This is because of the antiviral properties found in cassia. Many people will also add a few drops to a spray bottle and use it as a cleaning agent. Be sure to try it on a test area first before covering larger spaces to make sure that the product will not ruin anything in your house. An added benefit of using it on a frequent basis is that it is able to help reduce stress. If you are suffering from constipation or diarrhea you can also take the oil internally to help calm your body return to a healthy state.
Due to the nature of the oil, it can be very strong when put on the skin. If using topically on the skin, you should dilute 1 drop of cassia essential oil to 4 drops carrier oil like coconut or jojoba oil. When taking internally, many people will put it in empty gel caps, directly in their water, or by ingesting a drop with honey.
It is important to remember when using essential oils that quality matters. Not all products are created equal. You need to make sure that the oils you use are 100% pure and natural. I would only recommend using quality oils from known and respected brands.
