People can make ginger tea using fresh ginger or a store-bought tea bag. Although ginger is generally safe, some people may experience mild side effects — such as heartburn, diarrhea, gas, and abdominal pain — after consuming it.
This article will discuss the potential side effects of ginger tea, alongside some possible benefits.
It will also look at the safety of consuming ginger tea during pregnancy.
According to one 2019 systematic review, ginger can cause mild side effects. However, this is rare.
Some side effects — such as heartburn, diarrhea, and abdominal discomfort — might occur when a person consumes more than 5 grams (g) of it per day.
The sections below will look at these potential side effects in more detail.
Heartburn occurs due to acid reflux causing a burning sensation in the lower chest.
In one 2020 systematic review, 16 out of the 109 studies and reviews the researchers examined reported heartburn as an adverse side effect.
However, a 2014 article notes that consuming 1 g to 1.5 g of dried ginger per day can actually help treat heartburn.
The National Center for Complementary and Integrative Health (NCCIH) note that ginger may cause:
However, according to one 2016 article, ginger can increase gastric emptying. This, in turn, can help relieve the symptoms of abdominal pain.
Also, a 2019 article states that ginger can decrease the pressure on the lower esophageal sphincter, which can work to reduce gas and bloating.
Ginger may encourage bleeding. This is because it inhibits platelet thromboxane. This is a substance that platelets make that causes the blood to clot and constricts the blood vessels.
There are also concerns that ginger may interact with blood-thinning medications, such as warfarin, according to the NCCIH.
For this reason, people should avoid consuming ginger before undergoing surgery. Those with bleeding disorders should also talk with a doctor before consuming any form of ginger.
Although ginger tea can cause some side effects, it also has some potential health benefits.
The sections below will look at these in more detail.
Gingerols and shogaols, which are active compounds in ginger, may help relieve nausea and vomiting.
In one 2015 review, the researchers found that ginger extracts may help relieve pregnancy-induced nausea and vomiting, as well as chemotherapy-induced nausea.
A 2016 article suggests that using ginger may be an inexpensive, effective, and safe way to help relieve nausea and vomiting in those who are pregnant or undergoing chemotherapy.
Ginger may also help relieve pain and have an anti-inflammatory effect.
One study involved 60 adults with acute migraine. They reported relief after using 400 milligrams of ginger extract alongside nonsteroidal anti-inflammatory drugs.
A 2020 systematic review suggests that ginger may also be able to relieve menstrual pain, as well as pain that occurs due to osteoarthritis.
Ginger may also help relieve muscle pain. A small study involving 49 participants found that ginger decreased muscle soreness in athletes.
Ginger tea may help a person lose weight. For example, one 2018 review suggests that ginger may aid weight loss by:
Ginger tea may also help people with type 2 diabetes achieve better blood sugar control.
Researchers saw that consuming 2 g of ginger per day reduced fasting blood sugar and other vital indicators of diabetes.
For this reason, ginger may have a role in helping control blood sugar levels.
Ginger tea may help improve heart health and lower blood pressure.
Some research suggests that a daily intake of ginger may help lower the risk of chronic heart conditions by:
Ginger tea is safe to drink. However, people should avoid consuming more than 5 g of it per day.
The NCCIH suggest that those with gallstone disease should be cautious when using ginger. This is because it may increase the flow of bile.
One study examined 1,020 people who used ginger during pregnancy. The researchers conclude that using ginger during pregnancy did not increase the chance of:
However, pregnant people should still consult a healthcare provider before consuming ginger.
A person can make ginger tea using store-bought tea bags. However, if they want to make their own ginger tea, they can do so using:
The side effects of ginger tea may vary from person to person. It may cause heartburn, stomach upset, diarrhea, and bloating.
Although ginger tea comes with several side effects, it may also offer a wide range of benefits, including:
However, pregnant people and those with gallstone disease, diabetes, or high blood pressure should talk with their healthcare provider before incorporating ginger tea into their wellness regimen.
