Long Pepper (Pippali): Plant Profile, Traditional Use, and Modern Research
The 30-second answer
Long pepper is the dried fruit spike of Piper longum, a flowering vine in the Piperaceae family – the same plant family as black pepper, but a different species with a distinct chemistry and form. In Ayurveda it is called Pippali and is one of the most-cited single herbs in classical texts. Long pepper is one of the three ingredients in Trikatu and is described in classical theory as yogavahi – a substance that enhances the action of other herbs. Its primary active compounds are piperine and piperlongumine. As a food supplement in the UK, it is regulated under food law, not as a medicine.

- Doses studied: 250mg–1g daily as fruit powder or extract, 4–12 weeks
- Should not use: severe acid reflux, peptic ulcer disease, pregnancy, alongside medications metabolised by liver enzymes (without GP guidance)
What is long pepper? (and how it differs from black pepper)
Long pepper is one of those herbs that sits a little outside its name. It is in the same plant genus as black pepper, but it isn’t a long version of a black peppercorn. It’s a different species with a different fruit form, a sharper character, and a distinct historical and Ayurvedic identity.
The botanical name is Piper longum. The plant is a perennial climbing vine native to South India and Sri Lanka, growing through other vegetation by means of small adventitious roots. Its fruits are not the round peppercorns of Piper nigrum but dense cylindrical spikes – catkins, technically – composed of tightly packed tiny fruits fused around a central core. Spikes are typically harvested unripe, sun-dried, and used either whole or ground into powder.
The Sanskrit name Pippali appears constantly across classical Ayurvedic texts – more often than black pepper, in fact. Roman and Greek physicians knew long pepper before they knew black pepper; it travelled west along the spice routes earlier and was the dominant pepper in Mediterranean cooking until black pepper displaced it in the medieval period.
Same genus, different species, different fruit form.
Which parts of the plant are used?
The dried unripe fruit spike is the part used in modern supplements and traditional formulations. The root (called Pippali Mool in Ayurveda) is also used in classical preparations and has a slightly different application profile, though it is less common in modern supplements than the fruit. The leaves and vines are not used medicinally.
Did you know?
Until roughly 1000 CE, long pepper was the more important pepper in European cuisine and herbal medicine. The shift to black pepper happened gradually as Indian Ocean trade routes opened, partly because round peppercorns were easier to ship and store than fragile fruit spikes. Long pepper has had a quiet renaissance in recent decades among chefs and Ayurvedic practitioners.
Active compounds
Long pepper shares some of its phytochemistry with black pepper, but with notable differences. Piperine, the alkaloid responsible for the pungency of both species, is typically present in long pepper at higher concentrations – often 4 to 5 percent of dried fruit by weight, sometimes higher. This contributes to the herb’s reputation in classical Ayurveda as more strongly warming than black pepper.
The compound that distinguishes long pepper most clearly from black pepper is piperlongumine – a pippali-specific alkaloid that has been the subject of significant preclinical research over the past decade, particularly in laboratory studies of its biological activity. Long pepper also contains sesamin, methyl piperate, piperettine, and a complex volatile oil fraction.

A brief history of long pepper
c. 1000 BCE – 600 CE
Ancient and classical period
Long pepper appears prominently in the Charaka Samhita as Pippali and is described as a key ingredient in numerous classical formulations. It also appears in early Greek (Hippocrates, Theophrastus) and Roman (Pliny the Elder) medical and culinary texts, where it was the dominant pepper before black pepper supplanted it.
c. 600 – 1500 CE
Medieval period
The Bhavaprakasha and other medieval Ayurvedic texts described long pepper in detailed pharmacological terms, including the classical Pippali Vardhamana Rasayana protocol – a graduated dosing regimen used as a daily rasayana. In Europe, long pepper gradually gave way to black pepper through the medieval period.
1500s – 1900s
Niche persistence
Long pepper became a niche herb in Western markets but remained essential in Indian and South-East Asian Ayurvedic and culinary traditions. British colonial physicians catalogued it in detail.
1950s – 1990s
Chemistry
Indian and Japanese researchers characterised long pepper’s alkaloid profile through the second half of the 20th century. Piperlongumine was identified and structurally characterised, opening the way for the modern preclinical research era.
2000s – present
Renaissance and research
Long pepper has had a small culinary and herbal revival in the West, alongside expanded research interest in piperlongumine’s biological activity. Comprehensive reviews including Karkare 2012, Kumar 2011, and Bezerra 2013 pulled together the modern evidence base.
Traditional Ayurvedic context
In classical Ayurveda, long pepper is described as pungent, sweet (in post-digestive effect), light, oily, and warming. It primarily balances kapha and vata doshas. Classical texts describe it as yogavahi – a substance that carries and enhances the action of other herbs taken alongside it. This is the principle behind its inclusion in Trikatu and many other classical Ayurvedic formulations.
Pippali – yogavahi – that which carries the action of others.
— traditional Ayurvedic description
Traditional Ayurvedic descriptions of long pepper’s role include use as one of three components of Trikatu (with black pepper and ginger), the classical Pippali Vardhamana Rasayana graduated-dose protocol, traditional pairings with milk, ghee, and honey, and use as a yogavahi carrier in classical multi-herb formulations. These descriptions reflect classical Ayurvedic categorisation and historical use; they do not constitute claims about the effects of any modern food supplement.
Modern research
Long pepper’s human clinical evidence base is smaller than black pepper’s or ginger’s, with most modern research being preclinical (laboratory and animal). Where human studies exist, they are typically small. Comprehensive reviews provide the strongest synthesis of the available evidence. The studies described below are reported here as published research; the descriptions are not statements about the effects of any r‑veda product.

Reviews and syntheses
Karkare et al. (2012) provide a comprehensive published review of long pepper pharmacology, traditional uses, and clinical evidence. Kumar et al. (2011, Indian Journal of Natural Products and Resources) review Piper longum in detail. Bezerra et al. (2013) focus specifically on piperlongumine, the pippali-distinctive alkaloid, summarising the substantial preclinical literature on its biological activity.
Bioavailability research
Atal et al. (1981) examined the bioenhancer effects of Piper longum and isolated piperine in healthy adults, contributing to the broader understanding of how piperine modulates the absorption of other compounds.
Clinical research
Sahoo et al. (2013) studied 60 participants given long pepper supplementation over 4 weeks, with respiratory function endpoints. Other small trials have measured digestive endpoints but the human evidence base remains modest.
Preclinical research
The substantial volume of laboratory and animal research on piperlongumine has investigated cellular signalling, oxidative stress markers, and other endpoints. Translation to robust human trials remains an area where the field is still developing.
How to read this evidence base
Long pepper’s clinical research footprint is meaningfully smaller than that of black pepper or ginger. Most modern research is preclinical, focusing on the chemistry of piperine and especially piperlongumine. The strongest body of evidence supports long pepper’s traditional role as part of multi-herb formulations rather than as a standalone intervention – which aligns closely with how classical Ayurveda has always used it.
Forms and preparations
Long pepper has been consumed in several forms.
- Whole dried fruit spikes–ground fresh; the most traditional and most aromatic form
- Pippali churna–dried fruit ground to powder, traditionally taken with honey or warm water
- Trikatu–the classical three-pungent Ayurvedic formula combining long pepper, black pepper, and ginger
- Pippali Vardhamana Rasayana–a classical graduated-dose Ayurvedic protocol using long pepper as the main ingredient
- Capsule–dried fruit powder or standardised extract; often combined with other herbs in classical formulations
Doses used in clinical research range from 250mg to 1g of long pepper fruit powder or extract per day, taken with food, over study periods of 4 to 12 weeks. These figures describe what has been studied in research – they are not dietary recommendations.
Suitability and cautions
Long pepper is generally well tolerated at culinary doses. At supplemental doses, the same considerations as for black pepper apply, often more strongly given long pepper’s higher piperine content:
- People with severe acid reflux, peptic ulcer disease, or hyperacidity should avoid supplemental long pepper.
- People taking medications metabolised by liver enzymes – including some statins, certain antidepressants, anticonvulsants, and chemotherapy agents – should consult a GP before supplemental use, as piperine can alter their plasma levels.
- Pregnant women should avoid supplemental long pepper; culinary use is generally considered fine.
- People taking anticoagulants should consult a GP, as piperine may have mild effects on platelet function.
- Long pepper is more strongly heating than black pepper in classical Ayurvedic theory; people with high pitta or inflammatory tendencies may find it aggravating.
As with any food supplement, stop use and consult a healthcare professional if you experience any adverse effects.
