Tea is made from the leaves, stems, and buds of the evergreen shrub- Camellia Sinensis otherwise referred to as “the tea shrub,” a native shrub of East Asia (1). The black tea, green tea, and the delicious Oolong tea are all made from this plant. The process of making the Oolong tea starts immediately after the leaves are picked. The process ends in the pan firing stage after the leaves’ edges are reddened and aromatic substances are formed from partial oxidation. Oolong tea is a favorite, highly sought after for its health benefits. This article shares the nutritional value, benefits, and possible side effects of taking oolong tea.
What is Oolong tea?
Oolong tea is a traditional Chinese beverage representing 2% of the world’s tea. Its origin is traced back to the Fujian province of China, where it is still largely produced today. It is an intermediate between the green tea, which is slightly oxidized, and the black tea that is left to oxidize till it turns black. This traditional Chinese tea, also known as “wu long tea,” is left to oxidize from 8%-80%, which accounts for its robust taste and color (2).
The Oolong tea is made by naturally withering the freshly harvested leaves in direct sunlight. Then, the withered leaves are repeatedly shaken in a bamboo basket to bruise their edges lightly. After this, it is air-dried in the shade until the surface changes to a slightly yellow color (3). As a result, the Oolong tea’s flavor and color may vary widely depending on where it’s grown and how it’s processed. However, its benefits are universal and can significantly improve your skin, hair, and health.
