This tea cultivar was discovered in 1982[2], is not as widely planted as other teas and has a short harvesting period; it is a comparatively rare tea, and as such, is among the most expensive teas in China.[3]
It is called "white" tea although it is a green tea.[4] The long, narrow leaves are yellow in colour and have a recognisable fold along the length of the leaf.[5]
A 2010 study found that the tea is high in polysaccharides which can inhibit the hemolysis of blood cells.[6]
