Side effects of curcumin
Jun 04, 2019

Previous articles have already said that WHO's recommendation for Curcumin Granules

is no more than 200mg/d for adults per day, or no more than 3mg/d per kg of body weight. It is safer in this range, and generally does not appear too abnormal. It is not necessary to eat a large amount of food for the pursuit of effect. The so-called "too much" is not enough. Excessive use sometimes causes undesirable side effects. In addition, some people do not apply curcumin to their constitution and may also have adverse reactions.


One of the side effects of curcumin is that very few people have contact dermatitis. This skin disease usually begins with a rash and then disappears within 24-72 hours. In the absence of treatment, the skin will continue to itch and burn, and it may develop into blisters or measles later. Mild gastrointestinal pain is another side effect that is easily caused by high doses and long-term consumption of curcumin.

 Because it is often used to treat heartburn and hyperacidity, exceeding the recommended dose may result in nausea, even vomiting and diarrhea. Curcumin has the effect of stimulating uterine contractions and may lead to increased menstrual bleeding. These two factors are particularly prone to risk of miscarriage in pregnant women. Therefore, it is not recommended to consume large amounts of curcumin during pregnancy. The negative effects of curcumin also include the risk of bleeding. Because this substance can slow down the process of blood coagulation, it is not recommended for patients with bleeding disorders to consume. In addition, taking with drugs such as anticoagulants will further increase the risk of bleeding, so do not take curcumin for two weeks before and after surgery.


Another benefit of high-dose intake of curcumin is that it can cause liver and gallbladder poisoning. In fact, if gallstones already exist, taking curcumin can only make the problem worse. Taking curcumin in patients with specific diseases such as diabetes is particularly prone to cause serious side effects.

Many studies have confirmed that curcumin can lower blood sugar. If diabetic patients take blood sugar control drugs, taking curcumin can easily cause complications. In addition, curcumin also has the effect of lowering blood pressure, so people taking antihypertensive drugs should also avoid using curcumin.

One of the following conditions is recommended to reduce or avoid the use of curcumin in large quantities, or consult a doctor for use:

1. Pregnant women and lactating women;

2. young children;

3. Gallstones or biliary dysfunction;

4. Patients taking anticoagulants;

5. Female physiology period;

6. Diabetic patients;

7. Patients with esophageal reflux or other stomach diseases;

8. Iron deficiency anemia;

9. Prepare for 2 weeks before and after surgery;

10. Patients with calcium oxalate stones;

11. Those with impaired liver and kidney function;

12. Do not take it with other drugs while taking the drug;
