Ku Ding Cha was described in the Bencao Gangmu Shiyi (1765), originally called Dong Qing,This term, being rather general, led to some confusion about source materials, two groups of plants were being utilized for the tea: the holly (species of Ilex) and the wax tree (species of Ligustrum). Both the holly and wax tree are evergreens, their leaves have a somewhat similar appearance, and the wax insect that feeds off the wax tree is also found occasionally on the holly. The leaves of Ilex kudingcha (young plant pictured here) are long, slim, without the points common to other holly plants, and somewhat rubbery in texture

Considerable health benefit is attributed to Ku Ding Cha. In traditional Chinese medicine terms, it is used to disperse wind-heat, clear the head and the eyes, and resolve toxin, thus being used for common cold, rhinitis, itching eyes, red eyes, and headache. In addition, it is said to calm fidgets and alleviate thirst, especially when one is suffering from a disease that causes fever or severe diarrhea. It transforms phlegm and alleviates coughing, thus used in treating bronchitis. Finally, it is said to invigorate digestion and improve mental focus and memory.

Modern research suggests that the herb, whether derived from Ilex or Ligustrum, promotes blood circulation, lowers blood pressure, and lowers blood lipids, including cholesterol. It has the reputation of preventing deterioration of the heart and brain function and maintaining proper body weight. The main active components appear to be triterpene glycosides (saponins), which have been dubbed kudinosides and kudinlactones; it also contains polyphenols and flavonoids, somewhat like those found in ordinary tea
