A decaffeinated green tea isolated from Camellia sinensis, a plant native to Asia, with antiviral and antioxidant activities and potential chemopreventive activity. Green tea extract contains antioxidant compounds, including flavonoids, vitamins and polyphenols such as epigallocatechin-3-gallate (EGCG), which may have antineoplastic (ANTICANCER) properties. Consumption of green tea extract may confer chemopreventive protection against various cancers including those of the prostate, stomach, and esophagus.
Some people take green tea by mouth to prevent various cancers.
Green tea is also taken by mouth for Parkinson’s disease ,skin damaging.
Some people apply green tea bags to their skin to soothe sunburn and prevent skin cancer due to sun exposure.
Some people gargle with green tea to prevent colds and flu.
Green tea is used in an ointment for genital warts.
In food, people drink green tea as a beverage
When talking about health benefits, we must differentiate between teas made from the Camellia sinensis plant and those made from other botanicals. Technically, only beverages derived from the Camellia sinensis plant should be called tea and the others should be referred to as herbal tea, herbal infusions, or tisanes. In this section, we will focus on the potential health benefits of true tea, from the plant Camellia sinensis
There are five significant components found in all tea from the plant Camellia sinensis:
- Essential Oils
Each of these components work differently in the human body and a full description is best left to a medical journal. However, recent research exploring the potential health attributes of tea is leading many scientists to agree that tea of all types may contribute positively to a healthy lifestyle.
Within tea research, the most research that has been conducted has revolved around green tea in particular. Much of this research has been commissioned by Japan and China, major producers of green tea, in an effort to increase exports. While potential health benefits of green tea have been studied more often then other.
Did you know that up to 80% of the catechins in tea are not absorbed (or bioavailable) by the body? Most are lost in your intestine. However, researchers found that adding citrus to your tea may improve your body’s ability to absorb these beneficial catechins by increasing the acidity in your small intestine. In particular, a 50-50 tea/citrus mix had the greatest catechin-preserving effect, with lemon juice performing best, followed by orange, lime and lastly grapefruit juice. So brew your tea and flavor it with freshly-squeezed lemon, orange, lime, or grapefruit juice.
The tea plant is thought to have originated near the Yunnan region of China. The name Camellia sinensis is Latin for “Chinese camellia.” Due to its connection with the beverage, this plant is also commonly referred to as a tea plant, tea bush, or tea tree.
The China plant grows best in cool temperatures on steep mountain slopes. In fact, it thrives at elevations up to 9,500 feet. Because of the climate and elevation, the China plant will typically grow to between 5 and 15 feet tall, if left unattended, and produce leaves up to two inches long. The short mountain growing seasons yield a smaller crop of more tender leaves that yield a sweeter, less astringent cup.
AUSPICIOUS KNOWLEDGE ABOUT GREEN TEA (CAMELLIA SINENSIS)
Listed below are the possible health benefits associated with green tea. Green tea was used in traditional Chinese and Indian medicine to control bleeding and heal wounds, aid digestion, improve heart and mental health, and regulate body temperature.
Green tea and cancer prevention
According to the National Cancer Institute, the polyphenols in tea have been shown to decrease tumor growth in laboratory and animal studies and may protect against damage caused by ultraviolet UVB radiation.
In countries where green tea consumption is high, cancer rates tend to be lower, but it is impossible to know for sure whether it is the green tea that prevents cancer in these particular populations or other lifestyle factors.
Some studies have also shown the positive impacts of green tea on the following types of cancer:
- colorectal (bowel)
- esophageal (throat)
Green tea heart benefits
A 2006 study published in the Journal of the American Medical Association concluded that green tea consumption is associated with reduced mortality due to all causes, including cardiovascular disease. Green tea contains catechins, polyphenolic compounds that are thought to exert numerous protective effects, particularly on the cardiovascular system.
Green tea and lower cholesterol
An analysis of published studies in 2011 found that consuming green tea, either as a beverage or in capsule form, was linked to significant but modest reductions in total and LDL or “bad” cholesterol.
Green tea for type 2 diabetes
Studies concerning the relationship between green tea and diabetes have been inconsistent. Some have shown a lower risk of developing type 2 diabetes for green tea drinkers than for those who consumed no tea, while other studies have found no association between tea consumption and diabetes at all.
Green tea and inflammatory skin diseases
A 2007 study concluded that green tea could hold promise as a new treatment for skin disorderssuch as psoriasis and dandruff. Researchers studied an animal model for inflammatory skin diseases, often characterized by patches of dry, red, flaky skin caused by the inflammation and overproduction of skin cells. Those treated with green tea showed slower growth of skin cells and the presence of a gene that regulates the cells’ life cycles.
The antioxidants in green tea are excellent at fighting premature aging. Free radical damage is one of the leading causes of premature aging. These invaders are increased by an unhealthy diet, smoking, and environmental factors such as pollution. Antioxidants in green tea eliminate free radicals that can cause fine lines and wrinkles—the classic hallmarks of getting older.
Green tea contains a special antioxidant known as epigallocatechin gallate or EGCG. Scientific studies show that this tea antioxidant is effective in rejuvenating dying skin cells. EGCG effectively works to reactive the reproduction process of skin cells, giving dull skin a healthier glow.
Treats Oily Skin
Green tea contains tannins—biomolecules that bind with amino acids in the body. Tannins are naturally astringent compounds. This means they work directly as a skin toner to even out the appearance of skin. Tannins shrink pores ensuring that they clog less often.
Tannins also regulate sebum production, the skin’s naturally generated oil. People with oily skin tend to produce too much sebum, which results in clogged pores and acne breakouts. Most oily skin products aim to remove excess oil on the skin’s surface, but green tea targets the root cause by minimizing oil production in skin cells.
Clears Clogged Pores
Acne is one of the main skin problems people experience. The unsightly pimples and red skin can be hard to get rid of. Most doctors prescribe oral antibiotics or creams to target this stubborn skin disease. Unfortunately, many of these medications have negative side effects including dry skin, itching, and depression. Green tea is an effective acne treatment that helps to reduce pores and get rid of blackheads and breakouts without serious side effects.
Green tea leaves can be used to gently exfoliate the skin. Exfoliation helps to remove dead skin cells that can cause skin to look dull and lifeless. The exfoliation process also helps to trigger the production of new skin cells for a glowing appearance. Dried green tea leaves offer a slightly abrasive texture that softly removes dead skin. The antioxidants in the tea leaves also help to remove excess oil and dirt that can cause breakouts.
Reduces Puffiness and Redness
Green tea contains moderate amounts of caffeine. Tea tannins and caffeine both work to shrink blood vessels. This helps to reduce the look of puffy eyes and dark circles. Caffeine also brightens skin, resulting in an appearance that is glowing and rejuvenated.
Protects Skin From the Sun
We’ve focused on how green tea can be applied topically to protect skin. Since we’re all about drinking green tea, we couldn’t leave out the skin benefits of sipping a cuppa or two a day! Drinking a few cups of green tea every day can help minimize the sun damage caused by UV rays.
