Black Pepper: History and Traditional Use
No spice has moved more ships, or more money, than black pepper. The dried berry of Piper nigrum, a climbing vine from the rain-soaked hills of India’s Western Ghats, was packed into a pharaoh’s nostrils in 1213 BCE, priced by the pound by Pliny in first-century Rome, demanded by a Gothic king as ransom for the city, hoarded by a Tang chancellor, counted out as rent in medieval England, and chased around the Cape of Good Hope by the Portuguese. This article follows that documented trail from the Malabar Coast to the laboratory, where in 1819 a Danish scientist first crystallised the compound that gives pepper its bite, and where Indian pharmacologists later worked out why an ancient three-spice formula behaved as tradition said. Where the record is firm we say so; where a story is legend or tradition, we name it as such.

Origins, Botany and the Name
Black pepper is the fruit of Piper nigrum, a perennial woody vine of the pepper family, Piperaceae, that climbs trees and poles in the hot, wet forests of southwestern India. Its homeland is generally placed in the Western Ghats, the mountain range behind the Malabar Coast of what is now Kerala, where wild pepper still grows; the pepper cultivated across the tropics, from Sumatra to Brazil, descends from vines carried out of that region. The plant bears long hanging spikes of small round fruits (botanically drupes), which become peppercorns.
Black, white and green peppercorns all come from this one plant. Black pepper is the unripe fruit, scalded and dried until the skin wrinkles and darkens; white pepper is the ripe fruit with its outer layer soaked off; green pepper is the unripe fruit preserved fresh. None of them is related to the hot Capsicum “peppers” of the Americas, which Europeans named for their burn, or to pink and Sichuan “peppercorns,” which belong to other plant families.
One relative matters to the history. Long pepper (Piper longum), a catkin-shaped spike from the same genus, travelled the same trade routes and was for a long time the more prized of the two. The word itself preserves the confusion: English pepper descends from Old English pipor, from Latin piper, from Greek péperi, which in turn came from an Indian source related to Sanskrit pippali — the name not of black pepper but of long pepper. Black pepper’s own Sanskrit name is marica. Almost every European language took its word for the spice from the Latin, and the name settled on the round black berry as it displaced its longer cousin.
Maricha: Pepper in Ancient India and Ayurveda
India used pepper long before anyone abroad had heard of it. In Ayurveda, the classical medical system of the subcontinent, black pepper is maricha, and it appears in all three of the great foundational compendia — the Charaka Samhita, the Sushruta Samhita and the Ashtanga Hridaya — and in later drug glossaries (nighantus) such as the Bhavaprakasha. Dating these Sanskrit texts precisely is impossible; the surviving versions are conventionally placed in the centuries around the start of the common era. Within the Ayurvedic framework pepper is classed as pungent in taste and heating in potency, and it is prescribed above all as a deepana and pachana — a kindler of the digestive fire and an aid to digestion — and for coughs, breathing difficulty, colic and intestinal worms — the categories of that tradition, recorded here as history rather than proven mechanisms.
Pepper’s most enduring Ayurvedic role is as one third of trikatu, the “three pungents”: black pepper, long pepper and dried ginger in equal parts. It was used for sluggish digestion and respiratory complaints, and — a detail that would matter in the twentieth century — was routinely combined with other medicines in the belief that it helped them work.
The spice’s commercial home was the Malabar Coast, whose pepper gardens fed a string of ports, the most famous being Muziris, the emporium of the Chera kingdom near the mouth of the Periyar river. Its exact site was lost for centuries; excavations begun in 2007 at Pattanam in Kerala have produced the largest collection of Roman pottery yet found in India, and the site is now the leading — though still debated — candidate for the lost port.
Earliest Traces Abroad: A Pharaoh’s Nose and the Greeks
The oldest physical evidence of pepper outside India is also the strangest. Ramesses II, the great pharaoh of Egypt’s nineteenth dynasty, died in 1213 BCE. When his mummy was examined in Paris in 1976–77, botanists identified black peppercorns packed inside the nostrils, apparently placed there by the embalmers to preserve the shape of the famous nose. Because pepper then grew only in southern India, the find implies that a trickle of the spice was already crossing the Indian Ocean, by whatever chain of hands, more than three thousand years ago. Historians treat a single find in a single body with some caution, but it has not been overturned.
The written record begins with the Greeks. Theophrastus (about 371–287 BCE), Aristotle’s pupil and the father of botany, described pepper in his Enquiry into Plants (Book IX, chapter 20): “Pepper is a fruit, and there are two kinds: one is round like bitter vetch … the other is elongated and black and has seeds like those of poppy; and this kind is much stronger than the other.” He had already told black pepper and long pepper apart, and he recorded the Greek medical view that both were warming and were given with frankincense as an antidote to hemlock. Pepper was known in Greece by the fourth century BCE, but it was rare and costly — a physician’s drug rather than a cook’s seasoning.
Rome’s Pepper Habit: The Periplus, Pliny and the Pepper Warehouses
Everything changed when Rome took Egypt in 30 BCE and shipmasters learned to ride the monsoon straight across the Arabian Sea. A Greek merchant’s handbook of the mid-first century CE, the Periplus of the Erythraean Sea, describes the run from Egypt’s Red Sea ports to Muziris and Nelkynda on the Malabar Coast and names the cargo that made it worthwhile: “There is exported pepper, which is produced in only one region near these markets, a district called Cottonara.” The ships went out laden with coin, wine and glass and came back with pepper by the shipload.
Archaeology confirms the scale. At Berenike, Rome’s harbour on Egypt’s Red Sea coast, excavators have recovered black peppercorns by the thousand from more than 180 soil samples, and beside the town’s great temple they found a large Indian-made storage jar still holding about 7.5 kilograms of peppercorns, buried around the turn of the first century CE. The spice reached the far edge of the empire almost at once: peppercorns have been identified at Oberaden in north-west Germany, a legionary fortress of Drusus’s campaigns that tree-ring dating places in 11 BCE.
The Romans knew exactly what this cost them. Pliny the Elder, in his Natural History (about 77 CE), priced the three kinds of pepper at Rome — long pepper at 15 denarii a pound, white at 7 and black at 4 — and could not understand the fashion: “pepper has nothing to recommend it in either fruit or berry. To think that its only pleasing quality is pungency and that we go all the way to India to get this!” Elsewhere in the same book he reckoned that “by the lowest reckoning India, China and the Arabian peninsula take from our empire 100 million sesterces every year.” Yet the fashion held. In the Roman cookbook that goes under the name of Apicius, roughly four recipes in five call for pepper, and under Domitian (81–96 CE) the state built dedicated pepper warehouses, the Horrea Piperataria, beside the Sacred Way; their remains, beneath the later Basilica of Maxentius, were rediscovered in 1915 and opened to visitors in December 2024.
Dioscorides, in Book II of De Materia Medica (first century CE), classed pepper as warming and noted that the black kind was the more pleasant-tasting and the better for sauces; Celsus and, later, Galen listed it for coughs, for the eyes, for provoking sneezing and for its “warming and drying” qualities in the humoral framework of the day. Pepper was at once a food, a drug and a store of value, which is why, when the Visigothic king Alaric blockaded Rome in 408 CE, the historian Zosimus records that the city bought him off with 5,000 pounds of gold, 30,000 of silver, 4,000 silk robes, 3,000 hides dyed scarlet and 3,000 pounds of pepper.
Hu Jiao: Pepper Reaches China
Pepper reached China from the west and was named accordingly: hujiao, “foreign pepper,” the prefix hu marking goods that came in from the western regions. It first definitely appears in Chinese texts in the third century CE, and in 659 CE it was entered in the Xinxiu bencao, the Tang state materia medica, among drugs of foreign origin. It long remained a luxury. When the chancellor Yuan Zai was executed for corruption in 777, the confiscation of his estate is reported to have turned up, alongside the gold and silver, an enormous store of pepper — then an exceedingly expensive spice.
By the twelfth century pepper had become a fixture of wealthy Chinese kitchens, and when Marco Polo described Hangzhou (his “Kinsay”) in the late thirteenth century he reported being told by an officer of the Great Khan’s customs that the city took in 43 loads of pepper a day, each of 223 pounds — over four tonnes daily, for one city. In traditional Chinese medicine black pepper was, and is, classed as acrid and hot, a herb that “warms the interior and expels cold” and acts on the stomach and large intestine — the categories of a tradition, not modern pharmacology, and one more medical culture reaching independently for pepper as a warming digestive.
Black Gold: Pepper in Medieval Europe
When Rome fell, Europe’s pepper did not stop arriving; it simply passed through more hands. By the early Middle Ages the sea lanes from India were in Muslim hands, the spice moved up the Red Sea or the Persian Gulf to Alexandria and the Levant, and from there Venice and Genoa carried it into Europe at a handsome mark-up. Few Europeans had any idea where it came from. Isidore of Seville, compiling his Etymologies in the early seventh century, repeated the ancient tale that the pepper forests of India were guarded by serpents, that the harvesters set the woods alight to drive them off, and that ex flamma nigrum piper efficitur — the pepper turned black in the fire.
Scarcity made pepper into money. It changed hands as rent, dowry and tax, and medieval writers called it black gold. In England, the London trading laws attributed to King Æthelred (about 1000 CE, though possibly compiled later) required the “men of the Emperor” — German merchants — to hand over at Christmas and Easter two lengths of grey cloth and one of brown, ten pounds of pepper, five pairs of gloves and two saddle-kegs of vinegar. London’s pepper dealers were organised early enough to be fined for it: the Pipe Roll of 1180 lists the Gilda Piperariorum, the Guild of Pepperers, among eighteen “adulterine” guilds operating without royal licence, fined sixteen marks. That guild became the fraternity of St Antonin in 1345, charged with policing the purity of spices and drugs, and by 1373 was calling itself the Grocers — today’s Worshipful Company of Grocers.
The most durable relic of all this is a phrase. A “peppercorn rent” is still, in English law, a nominal payment that keeps a contract valid; it dates from a time when a few peppercorns were real consideration, and survived precisely because pepper later became too cheap to matter. The medieval historian Paul Freedman has argued that spices were valued as much for their scarcity and their remote, half-imagined origins as for their flavour.
Around the Cape: Portugal, the Dutch, the English and Salem
The price of pepper, and Venice’s grip on it, were among the chief reasons the Portuguese spent the fifteenth century feeling their way down the coast of Africa. On 20 May 1498 Vasco da Gama anchored off Calicut on the Malabar Coast, having sailed around the Cape of Good Hope; his dealings with the city’s ruler, the Zamorin, were difficult, but he got home to Lisbon in 1499 with pepper and cinnamon aboard and the route proven. For roughly 150 years the Portuguese crown ran the Cape route as a monopoly, with a fortified base at Cochin, and Lisbon rather than Venice became Europe’s pepper market.
The monopoly could not last, because pepper itself had already escaped India. Before the sixteenth century the vine was being grown in Sumatra, Java and the Malay peninsula, and the Dutch, whose first fleet under Cornelis de Houtman reached Indonesia in 1595, went straight for those sources. By 1605 the Dutch East India Company controlled the pepper centres of Sumatra and Java; in 1663 it took Cochin from the Portuguese and bound the rulers of Malabar by treaty to deliver their pepper to the Company alone. Dutch Malabar lasted until 1795, when it passed to the English East India Company, and all the while cultivation kept spreading through the archipelago, each new plantation weakening whoever held the old ones.
Even the young United States had a pepper age. In December 1795 the schooner Rajah sailed from Salem, Massachusetts, under Jonathan Carnes; he returned in 1797 from the north-west coast of Sumatra with about 140,000 pounds of pepper, kept the source secret for one more voyage, and set off a trade that made Salem the pepper capital of the world into the 1840s. The cumulative effect of all these routes was the one thing medieval merchants never faced: abundance. Pepper fell from black gold to an everyday grocery, and the peppercorn from a store of value to a figure of speech.
From Kitchen to Laboratory: Piperine, 1819 Onward
Nobody knew what made pepper hot until the age of chemistry. In 1819 the Danish scientist Hans Christian Ørsted — better remembered for discovering electromagnetism the following year — extracted a yellow crystalline substance from pepper and named it piperine, after the plant’s Latin name. It turned out to be the principal source of pepper’s bite, making up roughly 5 to 9 per cent of a black peppercorn by weight.
Working out its structure took another generation. In 1850 the Scottish chemist Thomas Anderson, and independently in 1852 the French chemist Auguste Cahours, broke piperine apart with nitric acid and obtained a simple ring-shaped base that Cahours named piperidine; piperine proved to be that ring joined to an acid, piperic acid. In 1882 Leopold Rügheimer closed the circle by putting the two halves back together, publishing his “artificial piperine” (Künstliches Piperin) in the journal of the German Chemical Society — the first synthesis of the compound.
Two further facts explain kitchen experience. Piperine is unstable in light, rearranging into tasteless isomers, which is one reason ground pepper in a clear jar goes flat while whole peppercorns keep their fire. And the plant’s own recipe for the molecule was read in 2019, when a chromosome-scale genome of Piper nigrum published in Nature Communications shed light on how the vine assembles piperine — two centuries after Ørsted first crystallised it.
Trikatu Revisited: The Bioenhancer Story (1929–2002)
The most interesting modern chapter of pepper’s history is the one that runs back to trikatu. In 1929 a researcher named Bose recorded that vasaka leaves (Adhatoda vasica), a traditional asthma remedy, worked better when pepper was added — an observation nobody followed up for half a century. In 1979 C. K. Atal, director of the Regional Research Laboratory at Jammu, took the old formula seriously and coined a new term, bioavailability enhancer (or “bioenhancer”): a substance that does little by itself but increases how much of a co-administered drug reaches the bloodstream. His group’s 1981 paper set out the evidence that piperine, the pungent principle of the trikatu peppers, did exactly that; a 1985 study in tuberculosis patients reported higher blood levels of the antibiotic rifampicin when piperine was given with it, and another paper that year showed why — piperine is a potent inhibitor of the enzymes that break drugs down.
The finding that carried the idea around the world came in 1998, when Shoba and colleagues, in Planta Medica, gave healthy volunteers two grams of curcumin — the poorly absorbed pigment of turmeric — with or without 20 milligrams of piperine, and found that the pepper compound raised curcumin’s bioavailability by about 2,000 per cent. That single result is why most turmeric supplements now contain black pepper extract, and it gave a scientific footing to a pairing South Asian cooks had used for millennia. In 2002 Bhardwaj and colleagues showed how it works: piperine inhibits both CYP3A4, a major drug-metabolising enzyme, and P-glycoprotein, the pump that ejects foreign molecules from intestinal cells.
That mechanism is also the modern caution: what helps curcumin across the gut wall can do the same for prescription medicines, so concentrated piperine supplements deserve more respect than the pepper mill does (see the companion Absorption and Bioavailability article). The historical point stands on its own: an Ayurvedic practice of combining pepper with other remedies, recorded some two thousand years ago, turned out to describe a real, measurable pharmacological effect.
Black Pepper Today
Pepper is still the most traded spice on earth, but its map has moved. World production was about 855,000 tonnes in 2023; the largest producer by far is Vietnam, with roughly 30 per cent of the total and an even larger share of exports, followed by Brazil, Indonesia and India. Kerala, where it all began, is now one producer among many, though Malabar pepper keeps its reputation as a premium origin. In the United States black and white pepper are listed by the Food and Drug Administration among the spices generally recognised as safe (21 CFR 182.10) — a regulatory footnote for something humans have eaten for three thousand years.
Where the science stands is set out in the Black Pepper hub and its Benefits pages: as a food, pepper is about as safe as anything in the human diet; piperine’s antioxidant and anti-inflammatory activities are real in the laboratory and largely untested in people; and its one well-proven effect in humans is the absorption boost described above, which cuts both ways. A berry that drained Roman treasuries, ransomed a city, helped launch the age of European exploration and named a legal doctrine owes its lasting medical interest not to anything it cures, but to what it does for other things. Tradition noticed first; chemistry explained it; and the vine goes on climbing in the Western Ghats, as it did before anyone wrote a word about it.
