普洱茶 (Pu’er or Pu-erh tea): Impact on Cholesterol levels

This article is based mainly on the below book.

木霁弘, 胡皓明, 胡波. 普洱茶. (2007). 北京 (Beijing). 中国轻工业出版社. [Found currently at the Bishan and Yishun branches of the National Library Board, Singapore]

Qualities

Apparently from the Kong Kong and Macau perspective, it is warm. (My uncle or 大 said years ago that it is not a cooling tea.) Green tea is 寒 or cool. Red teas are hot. (p. 95-96)

赵学敏, Qing dynasty China 1765, stated that for Pu’er tea: “…虚人禁用.” So like any types of foods/medicines, any successful use depends on whether a person’s constitution is suited to the remedy. (p. 89)

Cholesterol

According to a medical practitioner (廖朝崧, Internal Medicine/Cardiovascular Internal Medicine)  from 台大 (National Taiwan University or NTU), fat accounts for 14-30% of a person’s weight. It is made up of various components including cholesterol and triglycerides (another related biomarker). (p. 93-94)

Efficacy (p. 91-93)

Study 1: 台大台大科技研究所 – (NTU, non human trial) the tea prevents formation of cholesterol in the liver by 41%. But it took 3 times the typical daily amount/dose.

Study 2: (nomads in Mongolia and Xinjiang, China) Paris St Anthony Clinical Studies Department Head – 30% of frequent tea drinkers (which the population generally are) saw decline in cholesterol levels [but the sample size (N) is not stated].

Study 3: Another French source – 3 bowls (whose volumes were not indicated) of 云南沱茶 (a specific type it seems) daily. After 1 month, cholesterol levels fell 13% for some patients. The N is only 20. By most standards, N needs to be 30 and above to be statistically significant.

Study 4: 云南沱茶 juice used on mice – 10 to 30% reduction of cholesterol after 9 weeks.

Report: Japanese magazine <<Health>> – tea can lessen cholesterol and triglycerides
