The History of the Global Herbal Trade: Key Eras (2026)

The history of the global herbal trade is the long-distance movement of medicinal and aromatic plants, dried roots, bark, seeds, gums and prepared extracts between regions and cultures. It runs from Chinese and Egyptian materia medica through Silk Road and Indian Ocean caravans, colonial botanical transfer programmes, and today’s industrial supply of dried herbs and standardised extracts.

Six eras explain almost everything you see in that trade today:

• Ancient origins — written materia medica in China, Egypt, India and Greece, alongside early exchange of aromatic plants.
• The Silk Road and the spice routes — overland and maritime corridors built around pepper, cinnamon, cloves, nutmeg, resins and dyes.
• Medieval transmission — Arabic and Persian scholarship consolidating and extending Greek plant knowledge, then European monastic and apothecary practice.
• Printing and botanical naming — herbals that became trade documents, then Linnaean taxonomy giving every plant a stable name.
• Colonial botany — plantations, botanical gardens, forced cultivation and the extraction of indigenous plant knowledge without benefit sharing.
• The modern market — chemical standardisation, supplement and cosmetic demand, international regulation and a supply chain now measured in billions of dollars a year.

What Is the History of the Global Herbal Trade?

The global herbal trade is the exchange of medicinal and aromatic plant materials, and the knowledge needed to grow, identify and use them, across regions. It covers raw dried herbs, seeds, barks, roots, gums and resins, but also prepared products: oils, tinctures, standardised extracts and formulated remedies.

It overlaps with the spice trade without being the same thing. Spices were mostly valued for flavour, aroma, preservation and ritual use, and the famous spice commodities, pepper, cinnamon, cloves and nutmeg, are only a slice of what moved. Herbs moved for medicine, dyeing, perfumery, food preservation, tanning, incense and feed.

The main products and regions that carried the trade

Plant commodities fell into a handful of classes that stayed remarkably stable for centuries. Aromatics and spices came from South and Southeast Asia and the Moluccas. Resins and gums, frankincense, myrrh, gum arabic and benzoin, came from the Horn of Africa, Arabia and India. Medicinal barks and roots, cinchona, sassafras, ipecacuanha and sarsaparilla, moved out of the Andes, Central America and the Caribbean. Dyes and tanning materials came from India, the Mediterranean and later the American tropics.

The main regions are the Indian Ocean rim, the Mediterranean and Saharan corridors, Atlantic Europe and its plantations, East and Southeast Asia, West and Central Africa, and Latin America. Each supplied different materials, and each sat at a different point on the chain between wild or cultivated harvest and the consumer.

Why the topic matters: it explains how plants reached populations thousands of kilometres from where they grow, who profited from moving them, and why today’s debates over adulteration, wild-harvest pressure and benefit sharing sound the way they do.

How did herbs become international trade goods?

Plants became trade goods for practical reasons long before anyone wrote a pharmacopoeia. A dried root keeps for months when a fresh plant does not. A resin stays stable in heat and damp. A bark that is worthless as food can be worth a season’s labour as a dye, a medicine or a perfume base.

Why plant products travelled before medicine was standardised

Six product classes carried the early trade. Aromatics, pepper, cardamom, cloves and nutmeg, added flavour and slowed spoilage, so they paid for themselves in the kitchen as well as the apothecary. Medicinal simples, gums, barks, roots and seeds, were prescribed by weight and preparation with little standardisation, so traders sold reliable origin and freshness rather than a guaranteed active content. Resins and incenses, frankincense, myrrh, benzoin and labdanum, burned as offerings and used in perfume, and were lightweight and high-value. Dyes and tanning materials, madder, indigo, myrobalan and catechu, were urban manufacturing inputs. Perfume oils and balms, myrrh, rose water and attar of roses, followed elite demand across courts and caravans. Ritual and psychoactive plants, frankincense, coca, tobacco, opium and cannabis, crossed regions with worship and habit attached.

Preservation is the quiet reason behind most of this. Salt, sugar, drying and resinous aromatics were the four preservation technologies of the premodern kitchen, and every one of them is a plant product that travelled.

Which trade routes shaped the earliest herbal commerce?

Exchange was rarely direct between producer and buyer. Goods usually changed hands at several entrepots, each layer adding risk, tax and knowledge, which is why the same bark or root could be re-labelled three times before reaching a consumer.

Reading the history of the global herbal trade through its corridors makes one point clear: the routes were built for high-value, low-weight goods and for information as much as for cargo.

Overland corridors

The Silk Roads linked China, Central Asia, Persia, the Levant and the Mediterranean, carrying silk, paper, lacquer, tea, rhubarb, frankincense, precious stones and spices. The incense roads of Arabia and the Horn of Africa ran frankincense and myrrh north to Mediterranean ports and east to India. Trans-Saharan caravan trade carried gold, salt, gum arabic and khat between West Africa and North Africa. Central Asian routes moved rhubarb and medicinal gums into Persia and Ottoman markets.

Maritime corridors

The Indian Ocean monsoon system tied East Africa, Arabia, India and Southeast Asia into one network: dhows and lateen sails left with one monsoon and returned with the other. The South China Sea carried cloves, nutmeg, mace and camphor toward Malacca, which sat astride the Straits. Cape routes around Africa from the fifteenth century shifted European purchases from Levantine and Venetian brokers to Lisbon, then Amsterdam. The Manila galleon ran silver, porcelain and spices from Asia to Veracruz and American silver back to Manila. Atlantic plantation routes carried sugar, tobacco, cacao, indigo, sassafras and cinchona to European ports.

What changed during the ancient and medieval spice trade?

The spice trade grew because aromatic plants solved three problems at once. They preserved food in a world without refrigeration, they made bland staples palatable, and they carried medicinal and aromatic value, especially for camphor, cloves and nutmeg as drugs as well as condiments. On top of that, spices were taxed hard and imported from far away, which kept them scarce, which kept them valuable.

Pepper from the Malabar Coast supplied Europe, the Middle East and North Africa for roughly fifteen centuries. Cinnamon reached the Mediterranean from Sri Lanka and India through Arab and Venetian hands. Cloves and nutmeg moved from the Moluccas, the Banda Islands, across two seas to reach European markets, passing through Venice in its role as the great European entrepot of the fourteenth and fifteenth centuries before Lisbon and Amsterdam took over.

Saffron, the stigmas of Crocus sativus, was the most expensive of them by weight and moved from Iran and Kashmir through Persia and the Ottoman world to Europe. Frankincense and myrrh, resins tapped from Boswellia and Commiphora trees in the Horn of Africa, ran the incense roads to temple and church markets and then into perfumery and pharmacology.

Two things changed the map. Cumulative geographic knowledge, produced by Arab, Chinese, Greek and later Portuguese pilots, made voyages repeatable. And shipping capacity, from lateen-rigged dhows to multi-deck carracks and Dutch fluyts, cut freight cost per tonne sharply enough that spices stopped being luxuries reserved for courts.

Written records ran alongside commerce. Dioscorides’ De Materia Medica in the first century CE described hundreds of plants with their gathering sites and uses, and remained the reference for European apothecaries for well over a millennium. The Canon of Medicine compiled by the physician Ibn Sina, or Avicenna, in the eleventh century, organised Arabic, Persian and Greek materia medica into a systematic framework that later shaped both Unani medicine and European teaching. Monastic infirmaries kept physic gardens where herbs grew for the sick, and apothecaries in Italian and German cities stocked both locally grown simples and imported drugs.

How did African medicinal plants enter wider commercial networks?

African plants were early participants in long-distance trade, usually as raw materials for industries elsewhere rather than as finished medicines. Gum arabic tapped from Acacia senegal in the Sahel shipped from West African ports into European printing, textiles, confectionery and pharmacy. Frankincense and myrrh from Somalia, Ethiopia and southern Arabia fed incense, perfume and embalming trades spanning three continents. Shea butter and shea kernels moved from West and Central Africa into European soap and cosmetic manufacture. Khat from Ethiopia, Kenya and Somalia travelled the Horn of Africa as a daily stimulant, and in the twentieth century generated its own export economies and diplomatic disputes.

Three points are worth keeping straight when writing this history. First, most African plant exports were industrial raw materials, not packaged remedies, so a trade record showing sacks of gum says little about how local healers used the tree. Second, regional trade was older and larger than the export trade: kola nuts, shea, moringa and medicinal barks moved across the Sahara, the Sahel and the coast long before European buyers arrived. Third, forest and savannah products such as wild forest medicines, honey and gum arabic were often gathered opportunistically rather than cultivated, which made supply elastic and hard to regulate.

What did not travel was the documentation. Much African plant knowledge was oral, held by healers and families, and it left little written record that a later archive could catalogue. That asymmetry is one reason African contributions sit lower in most accounts of the global herbal trade than their economic weight would suggest.

How did colonialism reshape the global herbal trade?

Colonial rule turned plants into state-controlled commodities, and it did so on three fronts at once: production, science and knowledge.

On plantations, colonial administrations forced cash crops and medicinal plants into monoculture, with land, labour and yield managed for export rather than local use. Indentured and coerced labour moved people to those plantations. In British India, cinchona was moved from the Andes to Kew and then to Java in a bid to break the Andean monopoly on quinine bark. Conversely, rubber, cinchona, sarsaparilla, sassafras, ipecacuanha and cacao were carried from the Americas into Asian and African colonial economies.

Botanical gardens were the working infrastructure. Gardens at Kew, Calcutta, Peradeniya, Buitenzorg and elsewhere received seeds and specimens from colonies, grew them, and shipped both living material and dried herbarium material back to metropolitan laboratories. They were built for imperial advantage, yet they produced the botanical science of the modern world, and the plant records they created still back modern identification work.

Indigenous knowledge was the raw material of that science. Local healers’ knowledge of which plant treated which complaint was recorded, classified and patented by colonial institutions, with credit and compensation rarely flowing back. Convincing cases include rubber, chaulmoogra oil for leprosy, and the documentation that turned cinchona and ipecacuanha into pharmaceutical commodities. Those cases pushed the international benefit-sharing debate that eventually produced the Convention on Biological Diversity in 1992 and the Nagoya Protocol on Access and Benefit-Sharing, adopted in 2010 and in force since 2014.

The trade also shifted geography. Once voyages could bypass the Levantine brokers and sail around Africa or across the Atlantic, the profit centre moved from Alexandria and Venice to Lisbon, then Amsterdam and London, and the producing regions were pushed further into plantation monoculture rather than diversified local economies.

What drove the nineteenth- and twentieth-century expansion of herbal commodities?

Nineteenth-century industry turned herbs into measured inputs. Chemistry isolated active constituents such as morphine from opium, quinine from cinchona and caffeine from coffee, and pharmacy began buying botanical raw material by assay rather than by reputation. Standardised extracts, fluid extracts and later high-performance liquid chromatography fingerprinting let manufacturers guarantee a dose from a variable plant.

Patent medicines turned that into volume. Bottled preparations, pills and elixirs shipped through colonial and domestic retail networks, and firms built global brands on a few species. Cinchona, senna, cascara, ipecacuanha and sarsaparilla became industrial ingredients. Agricultural chemistry, refrigeration and rail and steamship freight cut spoilage and cost, and wartime supply pressure pushed governments to secure sources of quinine, opium substitutes and gaultheria oil.

The decline of plant material in the official pharmacopeia

Plant material lost official ground fast even as consumer demand held. Crude plant extracts were roughly 40 percent of official United States Pharmacopeia preparations in 1916, around 9 percent by 1950, and about 1 percent by 1990. The Flexner Report of 1910 reshaped medical education around laboratory science, antibiotics from the 1940s onwards supplied cheap and reliable substitutes, and synthetic chemistry gave formulators compounds no plant could supply at scale.

The twentieth century then rebuilt demand through new channels rather than through pharmacies. Food supplements, cosmetic botanicals, traditional medicine reforms and, later, e-commerce made raw dried herbs and standardised extracts international consumer products. Published estimates put herbal medicine use near 60 percent in most countries and between 70 and 80 percent in China, India, Africa and Germany, which keeps demand high even where prescription authority moved to chemistry.

How is the modern global herbal trade regulated?

Regulation today runs through four separate systems at once, and the difference matters more than most buyers realise. Food use, cosmetic use, traditional use and medicinal use each carry different rules for the same jar of dried leaves.

Botanical identification is the first gate. Trade names vary by country and by clinic, and a substitution error between closely related species can turn a standard preparation into an unrelated one. Quality testing then checks identity, potency, moisture, microbial load, pesticide residues, heavy metals and adulteration with cheaper lookalike material, often against a pharmacopoeial monograph. Protected species matter commercially as well as ecologically: international wildlife trade rules restrict unsourced collection of threatened plants, and buyers increasingly ask for collection permits and chain-of-custody documentation.

Customs classification decides whether a plant is a food, a pharmaceutical, a spice or a controlled substance, and that single decision sets duty, documentation and market access. Labelling rules differ again, with the United States treating most botanical products as dietary supplements under the 1994 supplement framework, and the European Union running a traditional herbal registration route based on traditional use alongside the stricter marketing-authorisation route.

Regulatory milestones in the herbal trade

Milestone	Year	Effect on the herbal trade
Convention on International Trade in Endangered Species	1973	Restricts international trade in threatened plant species and their products
WHO good manufacturing practice for herbal medicines	2003	Sets common manufacturing, documentation and quality expectations
WHO global strategy on traditional medicine	2003	Puts traditional medicine into health policy and regulation frameworks
EU traditional herbal registration	2004, applied from 2015	Creates a national listing route based on traditional use
Dietary Supplement Health and Education Act	1994	US framework that keeps most botanical products on the supplement market
Convention on Biological Diversity	1992	Sets national sovereignty over genetic resources
Nagoya Protocol on benefit sharing	Adopted 2010, in force 2014	Requires fair terms for use of indigenous and local knowledge

Harmonisation is still incomplete. A Chinese pharmacopoeia monograph, an Ayurvedic pharmacopoeial standard and a European monograph for the same species can specify different markers and limits, which means exporters often build to the strictest standard they can reach.

What are the main forces changing the herbal trade today?

Supply pressure is the first one. Wild collection of slow-growing species, including ginseng, arnica and some gentians, takes longer than the plants need to recover, and quotas and CITES listings now sit on the same species that international buyers want most. Climate change moves growing zones, shortens harvest windows and raises the failure rate for a crop that buyers expect on schedule.

Adulteration and misidentification run the other way, as substitution with cheaper plant material, undisclosed pharmaceutical additives and false certificate-of-analysis documents circulate through the same supply chains. Third-party testing and traceability records are becoming entry conditions rather than advantages.

Cultivation is the structural response. Many traded species are now farmed rather than wild harvested, which makes volumes predictable but reduces genetic variety if a narrow set of clones dominates. Fair-trade and regenerative-harvesting schemes exist but cover a small share of tonnage. Biopiracy and benefit sharing are the political edge of all this: the Nagoya Protocol asks access to genetic resources and associated knowledge to come with fair terms, and enforcement varies widely.

And demand keeps moving. Cosmetics, functional foods and supplements pull in botanical extracts, direct-to-consumer e-commerce shortens the chain from grower to buyer, and a buyer in Europe or North America can now order a single origin lot that a pharmacy counter would never have stocked.

The plants that dominate the world herb market today

Published reviews of world herb trade repeatedly name the same short list of species. These are the plants that carry the most traded volume, and each has a distinct path into commerce.

Most traded medicinal plants and their trade forms

Species	Common name	Main growing region	Principal trade form
Panax ginseng	Asian ginseng	China, Korea	Dried root, sliced, priced by age
Curcuma longa	Turmeric	India, Southeast Asia	Rhizome, dried and powdered, oleoresin
Zingiber officinale	Ginger	India, China, Southeast Asia	Dried rhizome, oil, oleoresin
Glycyrrhiza glabra	Liquorice root	Central Asia, Mediterranean	Dried root and root extract
Allium sativum	Garlic	China, Central Asia, Mediterranean	Dried bulb, aged extract, oil
Ginkgo biloba	Ginkgo	Cultivated in China and Japan	Leaf extract, standardised
Echinacea	Purple coneflower	North America, cultivated in Europe	Dried root and leaf, aerial parts
Hypericum perforatum	St John’s wort	Europe, cultivated worldwide	Dried herb, standardised extract
Silybum marianum	Milk thistle	Mediterranean, Eastern Europe	Seed extract, silymarin standardised
Rhodiola rosea	Roseroot, arctic root	Arctic and alpine Eurasia	Root extract

Published market estimates put the global herbal medicine market at roughly 165 billion US dollars, growing toward 350 billion by the end of the decade. Those figures cover finished herbal products rather than raw dried herb tonnage, and the two are not the same trade.

Conclusion

If you only read one part of this history, read the routes and the colonial section. Together they explain why the plants you buy were grown where they were, why their names vary so much between countries, and why questions about wild-harvest limits, adulteration and benefit sharing dominate the trade now.

Start with the timeline table for the shape of the whole story, then use the corridor table to trace a single material, such as frankincense or cinchona, from source region to end market. That end market part is where today’s labelling rules, pharmacopoeial monographs and supplement frameworks finally come into the picture.
