The ginger is one of the most prized ancient roots today, not only for its value as a traditional ingredient in Indian and Asian cuisine but also for its medicinal benefits . Both raw grated ginger and dried ground ginger are widely used as home remedies for the treatment of common ailments, such as nausea, loss of appetite, dizziness, and body aches.

Plus, it’s one of the most popular ingredients for relieving cold, sore throat, and cough symptoms , improving digestion, boosting energy levels, and even losing weight .

But did you know that its properties are not without worry?1

Contraindications: when is it not safe to take it?

Pregnant women

There is some controversy regarding the use of ginger in pregnancy. Although many women have used it safely to control morning sickness and vomiting , researchers warn that it can be counterproductive and dangerous at this stage if consumed excessively. It is believed that it can affect the levels of sex hormones, raise the risk of miscarriage, cause abnormal vaginal bleeding, uterine contractions, lead to the malabsorption of certain vitamins and minerals such as iron, among other negative effects.

It is important to consult your doctor before taking ginger in pregnancy, and especially to avoid it during the last weeks of pregnancy.

During lactation

Because there is not enough information yet4 on what could be the contraindications of ginger in breastfeeding, the researchers believe that, as a safety measure, it isbetter to avoid or reduce its usewhile breastfeeding a baby.

People with bleeding disorders or taking drugs for blood clotting

Taking ginger in these cases can increase the risk of bleeding , since its compounds have been proven to accelerate and increase circulatory activity in the body. Also, they are known to interfere with normal blood clotting in some people.5

Although drinking ginger tea can be very helpful in relieving pelvic pain and inflammation during menstruation, it is also not recommended for women with very heavy and prolonged menstrual bleeding.

People with inflammatory problems, gastritis and / or ulcers

People who have gastritis, an inflammatory bowel disorder, ulcers, or blockage in the intestinal tract are likely to experience adverse reactions if they overuse fresh ginger.

People who suffer from gallstones

Because ginger increases bile production , its use is not recommended for people with a tendency to develop gallstones.

Patients awaiting surgery

According to a group of researchers, taking ginger several days before having surgery can increase the risk of bleeding in the body . As a safety measure, it is recommended not to consume it for 15 days before or after a surgical procedure.6

Diabetic patients

Considering that the compounds in ginger can increase insulin levels and / or lower blood sugar levels, there is no doubt that it can be a good natural remedy to control type 2 diabetes; but its continued use may cause the need to make changes in the dose of the medical treatment being used due to the risk of hypoglycemia. Taking ginger without consulting a doctor in these cases can be counterproductive.

Patients with heart problems

Consuming high doses of ginger can worsen certain heart conditions. Its frequent use has been associated with an increased risk of cardiac arrhythmias and even heart attack in some people.

People under medical treatment

One of the most important contraindications of ginger in its interaction with certain medications. This includes beta-blockers , anticoagulants , insulin medications , barbiturates, and anti-platelet therapy .


In this sense, special emphasis is placed on people who take medications for hypertension , since it has been seen that the complementary use of ginger can result in blood pressure values ​​that are too low.


Those under treatment for thyroid problems should also be very careful with the consumption of the spice, since it seems that its compounds can interact with these medications and affect their function.

Note : Although several investigations have observed that the active substances in ginger can promote the health of the thyroid gland, it is known that their consumption affects thyroid function in some people, causing episodes of subacute thyroiditis.7

People who suffer from hemorrhoids

Although several studies cite ginger as one of the best natural supplements for hemorrhoid relief 8 , many specialists warn that its regular or excessive use can exacerbate symptoms. Like other hot ingredients, such as cayenne and hot peppers, gingercan cause dormant hemorrhoids to become seriously inflamed, causing great discomfort to the patient. It is recommended to consume it very carefully and avoid it as long as the condition is active.

In case of hemorrhoids accompanied by bleeding, it is very important to discontinue their use completely, since the anti-platelet activity of the gingerol compounds could lead to increased bleeding. 9

People with kidney disease or under treatment for the kidneys

So far there is no evidence that indicates that the simple fact of ingesting ginger puts the health of the kidneys at risk, however it is important to take into account its ability to interact with certain medications, which can indirectly affect kidney function .10 In general, special caution is recommended if you have stones, kidney infection, or have undergone a kidney transplant.
