Overview Information

White pepper grows in tropical Asian countries. Black pepper and white pepper both come from the same plant. But they are prepared differently. Black pepper is made by cooking the dried unripe fruit. White pepper is made by cooking and drying the ripe seeds.

People take white pepper by mouth to treat upset stomach, diarrhea, a specific bacterial infection that causes diarrhea (cholera), malaria, and cancer.

People apply white pepper to the skin to reduce pain.

White pepper is added to foods and drinks to add flavor.

White pepper essential oil is used in aromatherapy.

How does it work?

White pepper contains a chemical called piperine. This chemical seems to have many effects in the body. It seems to reduce pain, improve breathing, and reduce inflammation. Piperine also seems to improve brain function, but it is not clear how.


Uses & Effectiveness?

Insufficient Evidence for

  • Diarrhea.
  • Cancer.
  • A bacterial infection that causes diarrhea (cholera).
  • Malaria.
  • Pain.
  • Upset stomach.
  • Other conditions.
More evidence is needed to rate white pepper for these uses.

Side Effects

Side Effects & Safety

White pepper is LIKELY SAFE when taken by mouth in amounts commonly found in foods.

White pepper is POSSIBLY SAFE when taken by mouth appropriately as medicine. White pepper might cause an allergic reaction in some patients, although this is rare. White pepper might also cause a burning aftertaste. Piperine, a component of white pepper, has been reported to cause fast heart rate, nausea, headache, coughing, sneezing, and runny nose when used as a nasal spray.

Special Precautions & Warnings:

Pregnancy: White pepper is LIKELY SAFE when taken by mouth in amounts commonly found in foods. There isn't enough reliable information available to know if taking white pepper as medicine or applying white pepper oil to the skin is safe while pregnant.

Breast-feeding: White pepper is LIKELY SAFE when taken by mouth in amounts commonly found in foods. There isn't enough reliable information available to know if taking white pepper as medicine is safe while breast-feeding.

Children: White pepper is LIKELY SAFE when taken by mouth in amounts commonly found in foods. It is POSSIBLY UNSAFE when taken by mouth in large amounts as deaths have been reported.

Bleeding conditions: Piperine, a chemical in white pepper, might slow blood clotting. In theory, taking white pepper in amounts greater than those in food might increase the risk of bleeding in people with bleeding disorders.

Diabetes: White pepper might affect blood sugar levels. In theory, taking white pepper in amounts greater than those in food might affect blood sugar control in people with diabetes. Dosing adjustments for diabetes medications might be needed.

Surgery: Piperine, a chemical in white pepper, might slow blood clotting and affect blood sugar levels. In theory, white pepper might cause bleeding complications or affect blood sugar levels during surgery. You should stop taking white pepper in amounts greater than those in food at least 2 weeks before surgery.



We currently have no information for WHITE PEPPER Interactions.



The appropriate dose of white pepper depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for white pepper (in children/in adults). Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
