Camellia Oil

Start in a village kitchen on Jeju. In Shinheung 2-ri, in Seogwipo, the Visit Jeju tourism site describes villagers who tend tangerines by day and sort camellia seeds one by one in the evening, pressing them in the traditional way. Visitors can taste the oil stirred into a bowl of bibimbap. It is a small, modern tourism program, but it points to something older: the camellia (dongbaek-namu, 동백나무) is a food tree as well as a flowering one, and a Korean newspaper account of the winter-flowering tree notes that the pressed seed oil is used as an edible oil. The wider Korean pantry runs on toasted oils, and sesame and perilla oils are the everyday ones. Camellia oil is a regional specialty beside them.

A tree of the southern coast

The Encyclopedia of Korean Culture describes the camellia as an island and coastal tree, growing from Ulleungdo in the east to Daecheongdo in the west. On the mainland its wild range reaches up to Seocheon in South Chungcheong. A newspaper feature lists seven groves protected as natural monuments, from Daecheongdo to Geoje, Gochang, Gangjin and Yeosu. Jeju's Dongbaek Dongsan wetland takes its name from the trees that once grew thickly there, and the encyclopedia says villagers at times earned a living from camellia oil. For the island itself, see Jeju.

The classic hair oil

In the historical record the oil is most often a grooming product. The Encyclopedia of Korean Culture entry on hair oils (meorigireum) lists camellia first among the seed oils, alongside cornel (suyu), castor (ajukkari) and perilla. It says seed oils like these were prized because they were not sticky, had a mild smell and left hair soft and glossy, and that men used them too. The camellia entry reads folk songs that name camellia and castor together as reflecting their use on women's hair, and notes that the oil also fed lamps. Neither entry describes camellia oil as a cooking oil, so its culinary role is best treated as regional and recent rather than a documented national tradition.

The same hair-oil entry explains why oil bottles have round bodies and narrow necks: hair oil degrades in sunlight, and surviving examples range from Three Kingdoms earthenware to Goryeo celadon and Joseon white porcelain. For how this fits the larger beauty culture of the Joseon period, see Joseon cosmetics, and for the company that grew from a Gaeseong camellia-oil shop, see the rise of K-beauty. The wider hair story is in traditional hair care.

What the research shows

A 2007 paper in the Journal of Ethnopharmacology tested Camellia japonica oil in two ways. In lab cultures of human dermal fibroblasts, the oil activated a collagen-gene promoter and inhibited an enzyme that breaks collagen down. On people, the researchers measured water loss through the skin on the forearm, and ran an irritation test on the upper backs of 30 volunteers. The oil reduced water loss and caused no adverse reactions. The authors drew a cautious conclusion: it might be considered a candidate for wrinkle-reducing products. That is a small safety and moisturization signal, not proof of an anti-aging effect, and I did not find a controlled trial showing that the oil grows or strengthens hair.

Evidence status

• Traditional use: well documented for hair dressing and lamp oil; edible use is described in regional and press sources, not in the encyclopedia entries consulted.
• Skin: one small study combining cell work with a 30-person irritation test and a water-loss measurement.
• Hair: no clinical evidence found; historical use is about shine and grooming.
• Practical note: as with any plant oil, patch testing a new product before wider use is sensible.
