Lower Cholesterol and Blood Glucose Levels by Drinking PHatea®

Positive results from a human study in China of daily Fu Zhuan Tea (PHatea®) consumption to reduce blood LDL cholesterol prompted a study in Colorado of a group of volunteers with elevated cholesterol that were not taking medication for diabetes or high cholesterol.

The Advanced Integrative Medicine Clinic supervised by Dr. Randy Snook conducted the study with a group of individuals whose baseline LDL levels were between 100 and 200 mg/dl and had HbA1c of greater than or equal to 6%.


Positive results in other studies had suggested that daily consumption of PHatea would lower cholesterol and reduce blood glucose levels. Dr Snook’s objective of the study was to assess changes in blood lipid parameters for HbA1c after 120 days of daily consumption of PHatea, a fermented tea produced in the Hunan Province in China. Both tea consuming volunteers and the control group were not prescribed medications during the 120- day test.


  • There was a significant decrease in LDL cholesterol levels of test subjects proving PHatea’s assistance in lowering cholesterol
  • There was a significant decrease in HbA1c levels of test subjects indicating PHatea’s positive effect on Type 2 Diabete
  • After 120 days test subjects reported no adverse effects
  • Test subjects reported a marked decrease in appetite

Chinese green tea has long been known for the medicinal properties associated with halting the oxidation process by steaming the tea. Steaming the tea deactivates enzymes responsible for breaking down chlorophyll and producing tannins. Instead of stopping the process, PHatea continues with one or more microbial fermentation steps the change the chemical composition of the tea and darken its color.

Unlike most Chinese tea PHatea is fermented in a 32-step process that encourages the growth of Eurotium Cristatum, a fungus distinctive for its golden flower. When consumed, the fungus reacts and increases polysaccharides and polyphenols (theaflavins and thearubigins).

Polyphenols or theaflavins and thearubigins have an antioxidant property. The health benefits of ingesting theaflavins and thearubigns have been connected all the way from protection against dementia to inhibiting HIV-1 to aiding in weight loss. Many dietary supplements and anti-aging creams contain polyphenols.

In addition to the health benefits of the antioxidants, PHatea also activates pancreatic enzymes. Pancreatic enzymes control the metabolism of sugars and fats. When they are activated they suppress appetite and sugar cravings.

Not part of the formal study, test subjects who drank PHatea were asked to track their appetite. They reported a marked decrease in appetite while drinking PHatea.

Compiled anecdotal evidence has shown that drinking one liter of tea a day for 120 days has reversed blood sugar levels to < 100, assisted patients in losing eight, controlling insulin sensitivity, eliminating sugar cravings and lowering blood pressure.

In China tea is part of the culture. PHatea is well-known for its medicinal qualities and is widely consumed in China for hundreds of years. It is an important component of the diet of herdsmen in China. Existing on an animal-based diet of high fat foods and few vegetables, herdsmen consume fermented tea in order to digest properly and stay healthy.

PHatea is distributed in the US by The Golden Flower Trading Company and it comes in pressed coins or capsules. Both capsules or tea have the same health benefits.
