Osmanthus Oolong, an export product with traditional roots in Anxi, Fujian, the homeland of "Tie Guan Yin" tea, is primarily marketed in Hong Kong, Macau, Southeast Asia, and Western Europe. This tea is crafted mainly from the summer and autumn tea leaves of the current or previous year. Guìhuā Wūlóng features robust, thick tea leaves with a rich brown luster, an elegantly enduring fragrance, a mellow and lingering taste, and an orange-yellow infusion.
Oolong tea's health benefits have long been recognized, as described by the Tang Dynasty poet Lu Tong: "The first bowl moistens my lips and throat; the second bowl breaks my loneliness; the third bowl searches my barren entrails but to find therein some five thousand volumes of odd ideographs; the fourth bowl raises a slight perspiration, all the wrong of life passes away through my pores. At the fifth bowl, I am purified; the sixth bowl calls me to the immortals. The seventh bowl may not be drunk, only the pure wind of the cool valley raises in my sleeves." Similarly, in the Song Dynasty, Wu Shu wrote in "Tea Eulogy": "It relieves anxiety, quenches thirst, lightens the body, and its benefits are like those of a deity." Li Shizhen, in the Ming Dynasty's "Compendium of Materia Medica," stated: "Tea is bitter and cold, and it is the Yang within Yin, sinking and descending, and is most effective at reducing internal heat."
