Green tea has a better reputation than the captain of your high school football team, but is the hype true? Does green tea really have all the health benefits of a super-man like beverage? Here are the facts.
First of all, what exactly is green tea? We have all had a cup, but where does it come from? Green tea comes from a plant called Camellia sinensis. Despite its arguably weird name, this plant seems to be the parent of a very popular beverage. In leaf form, green tea is dried out and made into extract pills. Modern medicine has been able to dispel the facts and myths of green tea.
According to the National Institute of Health, green tea has long been claimed to approve alertness, lower blood pressure, promote weight loss, cure genital warts, ease stomach disorders, stop skin cancers, and cure cervical cancers. The list is not all inclusive. Despite most of the claims, there is little to no scientific evidence to validate using green tea as a curative medicine.
What claims may be true? Green tea ointment is FDA approved for genital warts. Secondly, green tea may promote alertness and focus. According to the data, these are the only 2 claims with scientific validity. In fact, the FDA approval for the treatment of genital warts is accompanied by a body of research. Green tea is a real medicine!
Which claims are ruled as “possibly true”? For a full list of claims that are partially true, please visit The National Institutes of Health’s website. Most interestingly, possibly true claims include lowering blood pressure after eating, reducing cholesterol, delaying onset of Parkinson’s disease, preventing dizziness upon standing, reducing HPV cells from growing in the cervix, and lowering the risk of certain cancers. For these claims, data is limited and ineffectiveness can not be ruled out. According to the data, green tea is probably not effective for preventing colon cancer.
Many other claims show insufficient evidence for green tea’s effectiveness. These include but are not limited to preventing kidney stones, breast cancer, gum disease, and diarrhea. Once again for a complete list visit the link above.
Green tea is relatively safe, but it is not recommended to consume more than 5-6 cups a day. Caffeine in green tea can result in side effects.
Overall, green tea has a huge market in America and across the world. If more research is conducted in the future, more claims might be proven effective! The upside is that green tea is relatively safe, so feel free to sit back and enjoy a cup of green tea today!
