Benefits of Tea - Green, Black, and Oolong Tea

Updated on January 8, 2014

Camellia Sinensis

Oolong, black, and green tea all come from one plant. These teas are derived from the plant “Camellia Sinensis”. The majority of the tea made from this plant is black tea. Of course, “Camellia Sinensis is the scientific name. In English, it’s simply “Tea”, in Hindi it’s known has “Cha” or “Chai”. No one is sure if a wild plant still grows. You can buy your own Camellia Sinensis to make your own tea. The plant is a forest plant, and of the class Equisetopsida. For centuries everyone thought black tea and green tea came from different plants. However the only real difference in the two is that black tea is fermented.

Green Tea

Green tea can be wonderful for warding off disease and helping a long a diet. There are some brands though that add harmful additives, so it’s recommended you check with your pharmacist about the particular brand you’re drinking. Green tea does contain caffeine, but very little. It’s helpful in cancer prevention, Parkinson’s disease prevent or delay, and lowering cholesterol. It is also used to help speed up the metabolism and assist in weight loss. Brewing the tea yourself at home will give you much more antioxidants and vitamins VS. buying bottled or canned tea from the store. As wonderful as Green Tea can be, it can also decrease the iron and folic acid you absorb. So it’s best not to drink it with your meal. More studies need to be done to learn which cancers Green Tea is affective for. Is already known that it is affective for some, such as breast cancer, prostate cancer, and lung cancer. It is believed, but not proven yet, that green tea is helpful in preventing cancers of the pancreas, ovaries, bladder, and esophagus. You should remember when doing research on health benefits of this tea that most studies have been done on the brewed tea, not supplements or extracts.

Black Tea

Black Tea is the most consumed in Western populations, according to a study done at Kings College in the UK. The polyphenols in the tea leaves go through changes during the processing, making them easier to identify in Green Tea. Those changes are the difference in Black Tea and Green Tea. Because of the complexity of the flavoniods in Black Tea, they don’t absorb as quickly into the body. The study at Kings College concluded that consuming enough of these flavoniods could help lower the risk of coronary heart disease. It’s also good for lowering a specific type of cholesterol, called lipoprotein. An animal study showed this tea has something better than an antioxidant effect. Black Tea can stimulate and anti-inflammatory effect, helping prevent a number of diseases.

Oolong Tea

Oolong Tea is considered ideal for certain ailments. Those with Diabetes, Hyperlipidemia, Coronoary heart disease, and high blood pressure. Oolong tea is also bad for certain things. People with insomnia, pregnant woman, habitual constipation, and peptic ulcers should stay away from this tea. Oolong Tea is often used to reduce chronic health conditions. Inflammatory problems, high cholesterol, and heart disease are among many things Oolong Tea can relieve. This Tea is packed with vitamins, antioxidants, and minerals. Oolong has enough caffeine in it to stimulate the nervous system, so drinking it late in the evening probably isn’t a good idea. The tea differs from Black Tea and Green Tea because it is only semi-fermented. It’s commonly believed the Oolong Tea can also help with obesity, do to the enzymes activated in the body. When those enzymes are activated, it enhances the functions of the fat cells. Another powerful antioxidant, Oolong Tea can also ward off many ailments. Oolong Tea was proven to be helpful to patients with eczema. These patients drank three cups of Oolong a day, and some saw improvements in one week.

Consult Your Doctor

If you are considering drinking tea to improve your health or for a health condition, you should check with your health practitioner to see which tea could be best for you. As stated, different brands mean different things. Your health practitioner may recommend a certain amount each day, or that the tea could be bad for you all together. There are many different types of tea in the world, I’m not a doctor but I’m sure there is something for everyone. Don’t be afraid to get out and explore the different types and flavors of tea.
