  • Q: What is the scientific evidence supporting Wu Long Tea?
    • 1. Basics of Tea
      • Tea comes from the Camellia family and is native to China. When the British went to India, they imported tea from China and eventually developed their own strain of tea. Thus, all tea comes from the same family of plants and all teas are very closely related. The only difference between teas made from the Camellia plant is the degree of oxidation of the tea leaves. Oxidation is also known as fermention. However, no microorganisms are involved in this process. Instead, fermentation refers to the the browning of the leaves as they are bruised and exposed to air. The process if very similar to the browning of an apple when exposed to air.

        Wu Long tea has long been made in China through a special process involving exposure to the air. What this does is spur chemical reactions between substances within tea. This process also gives the different types of tea their distinct flavor and color.Wu Long tea belongs between green tea and black tea in classification. Because it is neither full oxidized, nor left in its natural state, much skill is required to pick out a properly prepared batch of Wu Long. Wu Long tea is truly a craft on par with winemaking.

        To oxidize tea, manufactures harvest the tea leaves and hand roll the leaves to bruise them, exposing them to air for a period of time that requires artisan precision and experience. The leaves are then roasted in a pan coated with tea oil in order to lock in the flavor. Then, the leaves are dried and stored in a cool place for distribution.

        The grade of Wu Long depends on the age of the tea plants and the portion of the plant from which the tea leaves are picked. The younger the leaves used for tea, the higher the grade. Our Wu Long is a premium grade from mature Wu Long plants. However, we also provide rarer, higher grades of Wu Long that are picked from the spring buds of the tea plant. Because these buds occur only in the Spring, they are only available to our subscription customers and are considered a rare luxury even higher than the finest white teas.

    • 2. Wu Long Tea and Adipose (Fat) Metabolism
      • Wu Long tea is widely known by scientists to increase metabolism and fat burning. Some studies suggest that it burns fat better than green tea by 157%. Studies have shown repeatedly that drinking Wu Long increases energy expenditure. According to an Article titled Energy Expenditure of US Men and Japanese Women Consumer Oolong Tea by researchers at the Beltsville Human Nutrition Research Center, ARS, USDA, in Beltsville, MD; and the Department of Nutrition, University of Tokushima, and Research Center, Suntory LTD., in Japan, Wu Long energy expenditure, or the total calories metabolized by the body in a given day increased, on average, 3.8%. In women, a similar study showed that their body metabolism, as measured by a breath calorimeter, was higher in oolong tea rather than green tea. The scientists conclude that drinking Wu Long displays statistically significant effects on the Energy Expenditure of Human subjects. They further state that drinking Wu Long tea daily may also be useful for control of diabetes mellitus.

        In another article in the Journal of Nutritional Biochemistry (2001) Wu Long was also found to block fat absorption as well as fat storage in the liver and hears of rats who consumed sucrose rich diets. However, in this case, Green Tea was actually found to be more effective than Wu Long, leading to the conclusion that a mixture of Green and Wu Long may have the maximal health benefits we all look for.

    • 3. Wu Long Tea, Obesity, Diabetes, and Coronary Heart disease
      • Wu Long alone does however have unique effects against obesity and cardiovascular disease. An article in Diabetes Research and Clinical Practice 65 (2004) by researchers in Japan showed that Wu Long tea increased Adiponectin levels in patients with type 2 diabetes mellitus and coronary artery diesase. While water consuming groups showed no changes in adiponectin levels, a protein that is lowered in those with morose obesity, Coronary Artery disease, and Diabetes Mellitus, those who consumed Wu Long tea showed a significant difference in blood levels of adiponectin.

    • 4. Wu Long Tea's effect on Cholesterol Levels
      • Wu Long has also been shown to help balance levels of LDL and triglyceride levels by moderating the effects of LDL, a pernicuous cholesterol carried by low-density lioprotein. In a study by lead scientist H. Itakura of the Suntory Resaerch Center, Osaka japan, as well as H. Itakura of the National Institute of Health and Nutrition, Tokyo Japan, subjects who dranked Wu Long tea twice a day for 8 weeks had lower total cholesterol and triglyceride levels while HDL (good Cholesterol) levels were unaffected. Oxidation of LDL is believed to contribute to the development of atherosclerosis (Frei 1995). The scientists conclude that Wu Long "signficantly reduces LDL oxidation, total cholesterol and triglyceride and may be beneficial in the prevention of coronary heart disease.

        In another Study in Pharmacological Research, Vol. 35, No. 6, 1997 titled Hypocholesterolemic Effects of Chinese Tea , Yang and Koo, found that all Chinese teas including Jasmine, Green, Iron Buddha, and Pu erh all contributed to a lessening of liver weight due to fat deposits. Thus, a mixture of various Chinese teas may give a beneficial boost to liver health as well as heart health. If you'd like to sample other chinese teas please let us know!

    • 5. Wu Long Tea's Antimutagenic and Anticarcinogenic Activity
      • In a study by Y. Kuroda, and Y. Hara in Mutation Research 436 (1999), the authors state that the "polyphenols in tea have a strong radical scavenging and reducing activity...that capture and detoxify radicals of various promotors of carcinogensis and radicals produced in the process of exposure o radiation and light." Tea polyphenols as inactivate enzyme and virus activity and thus, may modulate the efficacy of viruses in producing cancerous by-products. Cathechins are in afar higher concentration in green teas and less oxidized teas such as Wu Long than in Black teas. The Japanese Cancer Association as well as the Ministry of Health and Welfare repored that death rate from cancer in both females and males in Shizuoka Prefecture was much lower than the mean for all of Japan. In additional, greater intake of a partially fermented tea, such as Wu Long was correlated with a lower risk of lung cancer in women. As little as 1-4 metric cups a day led to significant results, though the best results were obtained from women who drank 10 cups or more. Similar results were found for men.

        In female rats, Weisburger et al. reported that the volume of mammary tumors in female rates were decreased by 1.25% when the rats drank 2% tea beginning 1 week before carcinogen administration. The authors conclude by highlighting the effects of tea in the suppression of a rise in blood pressure and the reduction of blood glucose. Tea polyphenos also have an antibacterial effect against food borne bacterial was well as dental caries caused by bacteria.

    • 6. Wu Long Tea and Dental Health
      • In a study by the Institute for Natural Resources, Tea was found to contain naturally occuring Flourine which helps to prevent tooth decay. However, black tea was found to have overly high levels of fluorine that could lead to fluorosis, while green teas and oolongs did not exhibit the same effects. Thus Wu Long not only prevents tooth decay through its anti-microbial properties, but does so at a moderate rate that does not cause pernicuous damage to our bodies in the process.

    • 7. Wu Long Tea and Tobacco
      • In a study by the American Health Foundation published in Food and Chemical Toxicology 40 (2002) Tea was found to have chemopreventive effects through its antioxidants, detoxifying enzymes, and effects on cellular growth and natural cellular death (apoptosis) the opposite of cancerous cell growth.

        Tea has been found to kill Helicobacter pylori which causes ulcers and stomach cancer as well as inhibiting the effects of tobacco use in the oral cavity, esophagus, and lung. They conclude that the use of "a widely available, tasty, inexpensive beverate, tea, has displayed valuable preventitive properties in chronic human diseases."

        In addition, tea is a natural bronchodilator and anti-inflammatory for the lung tissue, allowing otherwise struggling cells to recover. Its effects on the lungs have already been noted in a previous section.

    • 8. Wu Long Tea and Nutrition
      • The effects of Wu Long are in addition to the effects of green tea. Wu Long tea is filled with vitamin C, Theanine, Polyphenols and enzymes that help break down foods so they are more efficiently metabolized.

        What this means is that your body goes after fat stored in your adipose tissue rather than glucose derived from your muscles. Since the muscles are a major engine of calory metabolism, normal diets actually cause your metabolism to slow because your body breaks down your muscle tissue for energy.

        Tea contains Pattasium, Phosphorus, Calcium, Bagnesium, Manganese, Selenium, Copper and Flourine among minerals found in tea. In addition, it contains Car0tin and Lutein, other powerful anti-oxidants found in carrots. Its Vitamin content includes A, B1, B2, C, E K, P U Pantothenic Acid, Folic Acid, and Niacinamide. Tea also contains detoxifying alkaloids such as Theine, Theophyline, Theobromine, and calming amino acids Theanine. Its. All this makes tea powerful for bone health, heart health and a natural anti-carcingoen. It is almost like wearing internal sunblock.
