Close-up of cubeb pepper (tailed pepper): flavor, cooking use and health facts

In the kitchen at a glance

Flavor:Hot / pungentWarm / woodyBitter

Aroma: Dry, woody and warm, with a camphor-like, peppery edge.

Used in: curries, soups and stews, baking, tea and drinks

Usual amount in food: USDA SR Legacy has no entry for cubeb pepper, and we found no source that sets a usual recipe amount.

What it is

Cubeb pepper is the dried, unripe fruit of Piper cubeba, a climbing vine in the pepper family. [1] It is grown mainly on Java and Sumatra, which is why it is also called Java pepper. [1][2] The berries look like black pepper but keep a small stalk, the "tail" in the name tailed pepper. [1][2] Do not confuse it with "false cubeb" or Ashanti pepper, Piper guineense, from Central Africa. [2] It is also sometimes confused with allspice and with cassia buds. [2]

Flavor and aroma

Cubeb tastes pungent and bitter, with a strong, dry, woody and warm smell. [1][2] Some writers compare it to allspice or to a mix of allspice and black pepper. [1] Katzer disagrees with the allspice comparison and calls the aroma warm and camphor-like. [2]

The oil in the berries is mostly terpenes, and sabinene makes up about half of it. [1][2] Katzer says the burn comes mainly from a compound called cubebin, not from the piperine that gives black pepper its heat. [2] A 2022 review instead lists piperine among the main compounds. [3] The sources disagree, so we do not say what causes the heat. Katzer says the cause of the bitterness is not known. [2]

How it is used in cooking

Cubeb is sold whole. Crush or grind it before use. [2]
  • North Africa: used in Moroccan savory dishes and pastries, and in ras el hanout. [1][3] Katzer places its use mainly in Tunisia and Morocco. [2]
  • Indonesia: a seasoning in Indonesian curries called gulai. [1]
  • Drinks: a flavoring in gin and in pepper vodka. [1][3]
  • Europe, past: a popular stand-in for black pepper in the 16th and 17th centuries, then dropped when black pepper became cheap. [2] Medieval cooks used it in sauces and as a meat seasoning. [1]

The sources we read do not say when to add it, whether to toast it, or what to use instead, so we give no rules. Because it is bitter and strong, start with very little and taste.

Normal food amounts

USDA SR Legacy has no entry for cubeb pepper, so we give no grams per teaspoon and no nutrient numbers.
MeasureGramsSource
1 teaspoonNot foundNo USDA entry
Typical recipe amountNot foundWe opened no source that states one

Cubeb is used in small pinches as a flavoring, so it adds almost nothing to the diet. We have no numbers to back this up beyond that common sense.

Buying, storing and preparing

  • Forms: whole dried berries with their stalks. [1][2] The oil and extracts are used by industry for flavoring. [3]
  • What good looks like: the wrinkled skin is grayish brown to black, and the seed inside is hard, white and oily. [1] Katzer says most berries are hollow. [2]
  • Mix-ups: Ashanti pepper has smaller, smoother, reddish berries with a curved stalk. [2] Wikipedia says cubeb has been adulterated with other Piper species, and that cubeb oil is sometimes used to adulterate patchouli oil. [1]
  • Storing and shelf life: the sources we read give no shelf life. A cool, dry, closed jar is the usual sensible choice for whole spices.
  • Availability: hard to find in ordinary shops. Look at specialty spice sellers.

Health: what research says

Using a pinch of cubeb in a dish is very different from taking a concentrated extract. For cubeb, the research is so thin that neither has been well studied in people.

Food amounts vs supplements

Typical amountNo usual amount found; no USDA entry [1][2]No official amount found
What studies mostly usedNo study of cubeb in food was foundFruit extracts and isolated compounds in cells and rodents [3]
What we can say about benefitNothing; no research on food amountsNothing reliable for people; one case report only [3]

The 2022 review says there is no systematic clinical research on cubeb and that how it works is not well established. [3]

Official statements

  • FDA (US): we did not find cubeb listed in the part of the US rules we opened on oils and extracts that are generally recognized as safe, and we cannot say how the US classifies it.
  • EFSA, EMA, WHO: we found no statement from these bodies that we could open.

What research links to this spice, and how strong the evidence is. Most studies use concentrated extracts or doses far above what you eat; each card says which.

Anti-inflammatory and antioxidant effects (cells and animals)

Lab or animal research only

The 2022 review lists antioxidant and anti-inflammatory effects of extracts and compounds in cell models and rodents.

Supplements: Not shown in people; nothing is known for food amounts.

Lab or animal research only

Extracts blocked enzymes such as alpha-amylase and alpha-glucosidase in test-tube studies.

    Cell and rodent studies report anti-inflammatory effects of cubeb extracts. Nothing has been shown in people.

  • AntioxidantLab or animal research only

    Lab studies report antioxidant activity of extracts. This does not show a benefit in people.

Root causes (1)
  • Lab assays show compounds from cubeb block a liver enzyme that processes many medicines. It is not shown in people or at food amounts.

Documented risks and interactions (2)
  • Possible change in how medicines are processed (lab only). In test-tube assays, several compounds from cubeb blocked CYP3A4, a liver enzyme that processes many medicines, about as strongly as ketoconazole.
  • Cubebin may irritate mucous membranes. Wikipedia states that cubebin, a compound in the fruit, irritates mucous membranes.

Frequently asked questions

Is cubeb pepper sweet?

No. It is pungent, bitter and woody, with a warm, camphor-like smell. [1][2]

How much is normal?

We found no source for a usual recipe amount, and USDA has no entry. Start with a small pinch of crushed berries and taste.

Is it safe in pregnancy?

The sources we read do not describe pregnancy. A small pinch in food is unlikely to be the concern, but ask your midwife or doctor about anything stronger.

Can I take it with medicines?

Lab tests show compounds from cubeb block a liver enzyme that processes many medicines. [4] No human study has shown this, and food amounts were not tested. Ask a pharmacist if you plan to take extracts.

Is it the same as black pepper?

No. It is a relative in the same genus, with a more bitter, woody taste, and its heat may come from different compounds. [1][2]

Does it help with any disease?

Not that research has shown. The evidence is lab and animal work plus one case report. [3]

Safety note at a glance
Cubeb is a rare spice with almost no human safety research. In lab tests, compounds from it blocked a liver enzyme that processes many medicines. [4] This has not been shown in people, but if you take medicine and plan to use cubeb as a supplement or extract, ask a pharmacist first. Small amounts in cooking have no documented problem in the sources we read.
Safety in more detail
  • Medicines: in a 2005 lab study, several compounds from cubeb blocked CYP3A4, a liver enzyme that processes many medicines, about as strongly as the drug ketoconazole did. [4] This was in test-tube assays, not people, and it used an extract, not food. We found no study of food amounts.
  • Pregnancy: the sources we read do not describe pregnancy. Check with your midwife or doctor before using more than a food pinch.
  • Breastfeeding: the sources we read do not describe breastfeeding.
  • Children: the sources we read do not describe children.
  • Allergy: the sources we read do not describe allergy to cubeb.
  • Liver and kidney: the sources we read do not describe harm. The review mentions one kidney case report with no side effects noted, which is too little to show safety. [3] Because the enzyme finding above involves the liver, people with liver disease should ask first.
  • Surgery: the sources we read do not describe a surgery warning. Tell the surgical team about any supplement.
  • Quality and contamination: mix-ups with other Piper species are described. [1][2] We found no source on lead or other contamination.
  • Amounts that cause trouble: in rats, a fruit extract up to 2,000 mg per kg and an oil up to 3,000 mg per kg caused no deaths, and no lethal dose was reported. [3] This does not tell us what is safe for a person. Wikipedia says cubebin irritates mucous membranes. [1]
