The seeds of Camellia oleifera mature from mid October to early November each year. The seed kernel contains 20% -30% oil (depending on the species, variety, and place of origin of Camellia oleifera), and is the raw material for producing tea oil. In addition to oil, Camellia oleifera seeds also contain abundant usable components such as starch, cellulose, lignin, and tea saponins.

The residue of oil tea seeds after being peeled or pressed without being peeled is called oil tea seed cake, also known as tea dry cake or tea bran. Camellia oleifera seed cake generally contains 5% to 8% residual oil. Through chemical solvent extraction, 4-6 kilograms of oil can be obtained for every 100 kilograms of cake, which is refined and processed into edible oil or other functional oils.

After extracting oil from Camellia oleifera seed cake, it is called Camellia oleifera seed meal. It is mainly used for extracting tea saponins and sugar terpenes, and can also be directly used as a pond cleaning agent and snail killing agent in aquaculture. Tea saponins have a wide range of applications in industries such as daily chemical, construction, mining, and pharmaceuticals, and can also be used as raw materials for biopesticides. Sugar terpenes are a mixture of tea saponins and sugars, which can be used as feed additives for livestock and poultry, partially replacing antibiotics, and have the effects of disease prevention and growth promotion.

The residue of tea saponin extracted from Camellia oleifera seed cake can be used as biological fertilizer and also in the production of feed.

The Camellia oleifera shell includes two parts: the Camellia oleifera fruit shell and the Camellia oleifera seed shell. The Camellia oleifera fruit shell is also known as the tea plant.

Camellia oleifera fruit shell and Camellia oleifera seed shell contain a large amount of lignin, hemicellulose, and cellulose, which have a wide range of industrial applications. They can be used to produce furfural, xylitol, activated carbon, potassium carbonate, and sodium lignosulfonate, extract tannin extract, and produce chemical products such as ethanol and levulinic acid. It can also be used to manufacture naturally degradable bioplastics and lightweight building materials.

Camellia oleifera is a rich source of honey, and its honey and powder are both nutritious and good beverages and foods, with medicinal value.

According to "Chinese Materia Medica", Camellia oleifera "has a bitter taste and a slightly cold nature. Its function and indications are to cool blood and stop bleeding. It is mainly used for vomiting blood, coughing up blood, epistaxis, rectal bleeding, uterine bleeding, and burns."
