Health Benefits of Tea: Green, Black, White and Herbal Tea

Tea is a name given to a lot of brews, but purists consider only green tea, black tea, white tea, oolong tea, and pu-erh tea the real thing. They are all derived from the Camellia sinensis plant, a shrub native to China and India, and contain unique antioxidants called flavonoids. The most potent of these, known as ECGC, may help against free radicals that can contribute to cancer, heart disease, and clogged arteries.

All these teas also have caffeine and theanine, which affect the brain and seem to heighten mental alertness.

The more processed the tea leaves, usually the less polyphenol content. Polyphenols include flavonoids. Oolong and black teas are oxidized or fermented, so they have lower concentrations of polyphenols than green tea; but their antioxidizing power is still high.

Here's what some studies have found about the potential health benefits of tea:

• Green tea: Made with steamed tea leaves, it has a high concentration of EGCG and has been widely studied. Green tea’s antioxidants may interfere with the growth of bladder, breast, lung, stomach, pancreatic, and colorectal cancers; prevent clogging of the arteries, burn fat, counteract oxidative stress on the brain, reduce risk of neurological disorders like Alzheimer’s and Parkinson’s diseases, reduce risk of stroke, and improve cholesterol levels.
• Black tea: Made with fermented tea leaves, black tea has the highest caffeine content and forms the basis for flavored teas like chai, along with some instant teas. Studies have shown that black tea may protect lungs from damage caused by exposure to cigarette smoke. It also may reduce the risk of stroke.
• White tea: Uncured and unfermented. One study showed that white tea has the most potent anticancer properties compared to more processed teas.
• Oolong tea: In an animal study, those given antioxidants from oolong tea were found to have lower bad cholesterol levels. One variety of oolong, Wuyi, is heavily marketed as a weight loss supplement, but science hasn’t backed the claims.
• Pu-erh tea: Made from fermented and aged leaves. Considered a black tea, its leaves are pressed into cakes. One animal study showed that animals given pu-erh had less weight gain and reduced LDL cholesterol.

Health Benefits of Tea: Herbal Teas

Made from herbs, fruits, seeds, or roots steeped in hot water, herbal teas have lower concentrations of antioxidants than green, white, black, and oolong teas. Their chemical compositions vary widely depending on the plant used.

Varieties include ginger, ginkgo biloba, ginseng, hibiscus, jasmine, rosehip, mint, rooibos (red tea), chamomile, and echinacea.

Limited research has been done on the health benefits of herbal teas, but claims that they help to shed pounds, stave off colds, and bring on restful sleep are largely unsupported.

Here are some findings:

• Chamomile tea: Its antioxidants may help prevent complications from diabetes, like loss of vision and nerve and kidney damage, and stunt the growth of cancer cells.
• Echinacea: Often touted as a way to fight the common cold, the research on echinacea has been inconclusive.
• Hibiscus: A small study found that drinking three cups of hibiscus tea daily lowered blood pressure in people with modestly elevated levels.
• Rooibos (red tea): A South African herb that is fermented. Although it has flavonoids with cancer-fighting properties, medical studies have been limited.

Water Temperature and Time

Natural flavoring in tea refers to flavoring substances derived from natural sources such as fruits, spices, herbs, or other plants. These flavorings are added to enhance the taste and aroma of the tea without the use of artificial additives or chemicals. Here's how it typically works:

1. Extraction Process: Natural flavorings are extracted from their source using methods like distillation, pressing, or soaking. For example, citrus oils might be cold-pressed from peels, or vanilla extract might be derived from soaking vanilla beans in alcohol.

2. Concentration: The extracted flavors are often concentrated to create a potent liquid or powder that can be blended with tea leaves.

3. Application: These concentrated flavors are carefully applied to tea leaves to achieve the desired taste. This might involve spraying the flavoring onto the leaves or blending them with dried fruits, flowers, or spices.

Examples of natural flavorings include:

• Citrus oils (like bergamot in Earl Grey tea)
• Vanilla extract
• Mint oils or dried mint leaves
• Fruit extracts (like peach, strawberry, or mango)
• Spices (like cinnamon or cardamom)

It's important to note that while natural flavorings are derived from natural sources, they may undergo processing to isolate the desired compounds. Always check labels or ask the tea producer if you’re looking for entirely unaltered ingredients.

Organic Pu-erh

Native to China's Yunnan district, pu-erh is cultivated from the plant Camellia sinensis, which also supplies other variations of tea. What makes this tea different from others is that pu-erh is fermented like oolong tea and then goes through another process known as post-fermentation. Once the tea is fermented, leaves are sun-dried and aged in a high-humidity environment. As it is popularly said, the more aged wine is, the better it tastes. Similarly, pu-erh tea gets better the longer it is aged.
