A popularly used method for weight loss, green tea as an herbal supplement has its own side effects too. Like every other general health medicine, you need to be aware of the negative effects green tea might have. You experience the negative effects when the intake of green tea exceeds the prescribed amount. Foremost, you should consult your doctor to know how much of green tea is safe for daily intake.
With this introduction, let’s talk about the possible side effects of consuming green tea.
In the mad rush to lose weight fast, it is common to see people consume weight loss supplements excessively. I hope you are not in this category because if you overdo consumption of green tea supplements, you will definitely face problems relating to intake of high amount of caffeine.
When compared to coffee, green tea has less amount of caffeine but if you happen to consume the supplements in excess, you have to face the consequences. Irregular heartbeat, headaches, rapid heartbeat, irritability, restlessness, jitters, diarrhea, loss of appetite, sleeping problems, stomach upset, nausea, frequent urination, skin rashes and vomiting are some of the side effects of green tea due to the presence of caffeine.
Apart from caffeine content, you may experience certain other problems, one of them being nausea. Green tea contains tannins. Now when you steep the green tea leaves for long, that is, more than 3 minutes, the tea begins to taste bitter and increased steeping doubles the amount of tannin in the tea you were about to drink.
Increased level of tannin tends to irritate the stomach, colon, and can also cause stomach upset. A study on 19984 on the negative effects of green tea on sensitive stomach showed that “tea is a potent stimulant of gastric acid, and this can be reduced by adding milk and sugar”. Remember never to drink green tea in empty stomach because it leads to nausea, therefore, have little snacks with green tea.
Doctors’ advice that pregnant women should stay away from green tea! Why? Green tea leads to the development of neutral tube defect in the baby. This is because of two reasons – the caffeine content and the presence of EGCG, an antioxidant found in tea which helps to lose weight but is detrimental for the baby. Therefore, as a precautionary measure, stay away from green tea when pregnant.
Also, if a woman is experiencing pre-menopausal syndrome, green tea is a disadvantage because there has been mixed evidence regarding green tea lowering the level of estrogen in the body, which aggravates hot flashes. However, when the green tea is taken with other herbs, it alleviates post menopausal syndrome.
Again, if any person is consuming blood thinning medication prior to surgery, he/she should avoid green tea as the tea has blood thinning properties. Moreover, green tea resists or prevents blood clot formation.
Apart from these negative effects, green tea, in any form, is safe to consume. Just keep in mind not to overdo its intake in any way.
