Camellia oil, also known as tea seed oil, is the actual green tea oil. It comes from the seeds of Camellia sinensis, the plant from which all the tea is made. Tea seed oil is wonderfully healthy in more ways than one. It is great for cooking, and from a nutritional point of view. Tea seed oil is used in some beauty products. This oil has been used as cooking for centuries in Southern China, and they make many more uses with it.
Camellia oil is extracted from the seeds of the tea plant. That makes it the natural tea oil. Tea tree oil, on the other hand, does not come from the tea plant. It comes from the tree called Melaleuca alternifolia, which is native to Australia. There are some varieties of Camellia oil.
- Camellia sinensis oil – This is the tea seed oil.
- Camellia japonica oil – Also known as Japanese tea oil. However, this plant does not produce tea leaves. It is a flowering plant with red blooms. Its oil is known as Tsubaki oil, and it is used heavily in cosmetic applications.
- Camellia oleifera oil – This is known as tea oil or Camellia oil.
So, technically the naming can be a bit confusing. The Camellia sinensis and oleifera oil are referred to as Camellia oil in general and may be used interchangeably. The Camellia Japonica oil is better known as Tsubaki, and it is also different in terms of its chemical composition and nutritional value.
The oil is extracted using solvent extraction or cold processing. One might hear about cold-filtered oil, but that does not mean cold-pressed oil. If the contents used to make oil are heated before oil extraction, it might change the chemical composition and properties of nutrients in that oil, which is often not natural.
Tea seed oil production is well monitored using quality control techniques . This oil has great commercial value in China as a considerable fraction of the population uses it. The oil is also getting attention from prominent international organizations like FAO. Since it is used as cooking oil, it needs to be correctly monitored for its fatty acid profile.

Fatty Acid Nutritional Profile of Camellia Oil
Tea seed oil is almost 90 % unsaturated fat, which is unique among oils. It is, therefore, a heart-healthy oil that has been identified to lower LDL cholesterol levels and harmful triglycerides from the body. Of this unsaturated fat, oleic acid makes a significant part. This is the complete fatty acid composition of camellia oil. This oil is pretty low in omega-3 fatty acid, but a significant amount of omega-6 is present.
|Gamma Linoleic Acid (18:3)||–||PUFA|
|Stearic Acid (18:0)||1.1 %||Saturated fat|
|Palmitic Acid (16:0)||8.8 %||Saturated fat|
|Palmitoleic Acid (16:1)||1.5 %||MUFA|
|Oleic Acid (18:1)||82.3 %||MUFA|
|Linoleic Acid (18:2)||7.4 %||PUFA|
|Alpha Linolenic Acid(18:3)||0.2 %||PUFA|
|Erucic Acid (22:1)||–||MUFA|
|Gadoleic Acid (20:1)||–||MUFA|
|Behenic Acid (22:0)||–||Saturated fat|
|Arachidic Acid (20:0)||–||Saturated fat|
Besides healthy fats, Camellia oil also contains some nutrients. It contains Vitamin E and minor amounts of other vitamins and minerals. Some of the minerals in this oil are calcium, phosphorus and potassium. Tea seed oil, however, gets its major health benefits from a whole range of micro-nutrients. These are the prominent nutrients from tea seed oil.
- Squalane – Possibly anticancer compound. It is commonly found in shark oil.
- Saponins – These compounds lower cholesterol and reduce the risk of heart disease.
- Kaempferol and its glycosides – These are strongly anti-inflammatory compounds, like quercetin. They help to protect the body from damage by inflammatory conditions.
