A commonplace beverage for many Asian countries green tea is an abundant source of useful nutrients such as catechins, a family of powerful antioxidants. Green tea extract, a condensed green tea supplement that features high quantities of catechins, has been studied for its ability to fend off a variety of health issues, which range from cardiovascular disease to morbid obesity. In accordance with the University of Pittsburgh Medical Center, studies at some level seem encouraging but have produced different results. So it is not fully shown that taking green tea supplements will deliver any health benefits. Like medications, all-natural supplements may yield side effects, plus some possible interactions with medications have been observed when using this health supplement. Consult with your physician prior to taking green tea extract or other kinds of herbal treatments if you use prescription medications.
Antidepressants and Sedatives
The content of caffeine in green tea extract may affect the actions of drugs like benzodiazepines, a group of medications generally used for treating anxiety and similar disorders. This could mean possibly decreased effectiveness in treating nervousness, anxiety, sleeping disorders and similar health issues. Combined usage of green tea extract and MAOI’s – a group of antidepressant medications – might lead to harmful increases for blood pressure levels, according to Maryland University Medical Center. It may also reduce the effectiveness of a drug called lithium, used for treating people who are bipolar.
Some discussion exists about using antioxidant supplements during chemotherapy, because in some cases they might make the medications less capable of eradicating cancerous cells. The Maryland University Medical Center reports scientific studies that discovered that using extracts of green tea actually helped chemotherapy medications be more effective, however, in one case it activated the growth of a specific gene that reduced the sensitivity of cancerous prostate cells to the activities of chemotherapy medications. Due to the possibility of interference with the performance of these anti-cancer treatments, consult with your physician with regards to the suitability of taking green tea extract if you’re presently undergoing chemotherapy.
