Fuzhuan Tea (also called Fu Tea, Fu Zhuan Tea, or Chinese Brick Tea) is a type of fermented tea made from the Camellia sinensis plant, traditionally grown and crafted in the mountainous Hunan Province of China. The tea leaves were known to be processed during the hottest days of summer and fashioned into bricks (the Chinese word for brick is "Zhuan").

Fu Zhuan Tea is fermented with the fungus, Erotium cristatum (Eurotium cristatum), and contains a unique phytochemical profile attributed to its unique method of processing.[1]

Healing Properties

  • Regulation of blood lipids.
  • Immune activation effects: of the fungus, Eurotium cristatum, found in Fu Zhuan Tea.[2]

Disease / Symptom Treatment

  • Hyperlipidemia: A condition in which there are high levels of fat particles (lipids) in the blood. Examples of lipids include cholesterol and triglycerides. These substances can deposit in blood vessel walls and restrict blood flow. This creates a risk of heart attack and stroke.
    • Fu Zhuan Tea has been shown to activate pancreatic enzymes and regulate blood lipids.[1]
    • Significant changes in blood lipids were detected after 120 days of daily consumption.[1]
  • Cardiovascular disease:[1]
  • Type 2 diabetes:[1]

    Abstract: Emerging evidence supports health-promoting properties of post-fermented Chinese Brick Tea. Fu Zhuan Tea, fermented with the fungus, Erotium cristatum, contains a unique phytochemical profile attributed to its unique method of processing. Fu Zhuan Tea has been shown to activate pancreatic enzymes and regulate blood lipids in laboratory models. Regulation of blood lipid levels by Fu Zhuan Tea consumption was examined in an observational pilot study of volunteers with elevated LDL cholesterol that were not taking any prescription lipid lowering medications. Significant changes in blood lipids were detected after 120 days of daily consumption. Fu Zhuan Tea fractionation led to the investigation of six compounds for regulation of transcription factors involved in lipid metabolism, including Farnesoid X receptor (FXR), Liver X-activated Receptor (LXR) and two isoforms of the Peroxisome Proliferator-Activated Receptors (PPARγ and PPARδ). Reporter gene assays with liver cells revealed dose dependent differences in regulation of transcription factor activation. These data reveal potential therapeutic efficacy and candidate molecular targets for Fu Zhuan Tea, and provide rationale for chemical characterization of bioactive fractions and investigation of therapeutic efficacy in cardiovascular disease and type 2 diabetes.

    Abstract: The immunization effect of Eurotium cristatum isolated from Fuzhuan brick-tea was evaluated. Ethyl acetate extraction (E2) had an increasing effect on T cell subset proportions. And then four compounds (physcion, echinulin, catenarin and emodin) were isolated from E. cristatum. The immunization effect of echinulin was observed through determining T cell subsets’ percentage, DNA synthesis and cytokine levels. It suggested that the immunization effect of compounds might work in relation to its structure. In addition, echinulin accelerated protein of p65, IκBα upregulation and nuclear translocation of p65 by the NF-κB signaling pathway. The result showed that the immunization effect of echinulin is closely related to the activation of NF-κB activity. Meanwhile echinulin increased transcript levels of p65 and IκBα in T cells at 200 μM (middle dosages group). It demonstrated that the immunization effection of echinulin on T cells is enhanced by activating NF-κB signaling pathway.
