Tea Medicine Series: Pu-erh (poo-air)

Pu-erh tea (‘poo-air’) contains high levels of polyphenols (flavonoids, catechins and theaflavin), which are beneficial antioxidants. Fat metabolism and stress reductions have been found to be beneficial side effects from inclusion of these naturally present chemicals in food sources.

Pu-erh has become more accessible in the United States, but it is still not as well known as some of the more classic black, oolong, green, or white teas. Teavanna, David's Tea, Numi's and other larger distributors have begun to scale and made Pu-erh more available. You will find that many of these retailers include 'cacao nibs' or 'chocolate' flavor to make it more palatable to the American consumers. Pu-erh by themselves are more of an acquired taste since most popular teas consumed here in the US are not fermented--yes this tea has been aged. Before you prematurely dismiss its place in your arsenal of food medicine, think about how we love kombuchas, 60-day dry-aged beef, and aged cheese. This should not dissuade one from trying it and appreciate its value as a complementary medicinal food in your everyday lifestyle.

So, what's the big deal?

#1 Helps manage Cholesterol

Aging and fermentation process of pu-erh tea can result in the production of small amounts of product that act as natural statin. Those of us who have history of high overall LDL numbers take statins either to treat a dangerous situation or as a preventative measure recommended by their primary care doctors if they detect an unhealthy trend indicated in their patients' blood panels. Reduction of LDLs and raising HDL numbers is vital to avoiding serious medical issues in these patients. Health benefits of including tea is gentle and cumulative; meaning, if you have a emergent health condition that requires more aggressive measure, you must consult with your medical professional first. For others who are already receiving reliable medical care, teas such as Pu-erh can be a great addition to a new healthier lifestyle.

#2 Digestion

In Traditional Eastern Medicine, pu-erh tea is considered to benefit the middle jiao (stomach/digestive tract) Pu-erh helps aid digestion and has detoxing quality. Although eating pre-packaged meals or foods that are highly processed is not recommended, practically speaking, eating clean all the time may not be possible for everyone. If such is the case, we can carve out days each month to detoxify with nutrient dense foods. In the meantime, adding green tea and pu-erh tea may mitigate some of the damage.

#3 Helps with Weight Loss

Pu-erh tea helps suppress fatty acid synthesis (FAS). Lipogenesis (liver's mechanism of creating fat) is slowed by this tea. The natural source of caffeine found in pu-erh motivates your body to secrete the hormones epinephrine and norepinephrine which are shown to increase metabolism of stored fatty acids in fat cells. Our bodies store fat for a good purpose, which is to use it later when we have calorie deficit. When fat is metabolized for use more efficiently, your body can access fatty acids as fuel and thereby not storing it as excess fat around your hips and belly.

Tea Medicine Series: Hawthorn

This little gem is also known as Shan Zha. Hawthorne may be new to us, but it is a medicinal supplement that has been used throughout history throughout Asia, Europe and North America for its health benefits.

The leaves and flowers contain beneficial flavonoids and procynaidins. Flavonoids activate endothelium-derived relaxing factor and inhibit phosphodiesterase, thereby increasing vasodilation. Therefore, patients who take warfarin/Coumadin, vasodilating, antiplatelet, and/or anticoagulant medications should make sure dosage of this herb is moderate.

Hawthorn fruit herbs are often included in herbal formulas for indigestion. Hawthorn fruit helps break down animal fat and supports digestive function. It has been found to be effective in lowering serum cholesterol and blood pressure. [1] [2]

Check your family medical history and examine your daily diet. If you are concerned about your heart health or have history of high LDL levels, a small dose of hawthorn tea may benefit you. Every little bit counts!

Alcohol Abuse Related Disease Now Affecting Children

Fatty liver diseases are often associated with alcohol abuse. Unfortunately, Non-Alcoholic Fatty Liver Disease (NAFLD) is thought to be the fastest growing cause of liver disease in both Western and developing world. What is causing excessive fat accumulation in liver cells in people who do not abuse alcohol?

Researchers posit that dietary consumption of fructose and uric acid concentrations may play a significant role in disease progression in NAFLD. Please refer to the original study for further in-depth information.

Whether the study is conclusive or not, there is no reason to not make healthful modification to mitigate potential health problems--especially for children. Replace sodas and juices with healthier options such as tea (oolong, green, pu-erh tea, and black teas are excellent choices to combat western diets) and whole fruits instead of juices (yes, including natural/ organic sources) as juices contain high concentrations of fructose. Nature provides balance when we consume whole fruits--natural sugar, fiber, and satiation when consumed naturally.
