01 / Reading the record

One plant.
Many kinds of evidence.

Cannabis had a real place in several healing traditions and in nineteenth- and early twentieth-century pharmacy. Understanding that history requires keeping the type of evidence visible.

01 / THE OBJECT

A bottle establishes existence.

The 1933 Parke-Davis artifact shows that an established pharmaceutical manufacturer supplied a cannabis preparation. One surviving bottle cannot tell us how common prescribing was. [11]

02 / THE TEXT

A record establishes a reported use.

A materia medica entry, testimony or case report documents what people described, prescribed or believed. It must be read in its language, era and institutional context. [1] [6] [9]

03 / THE INFERENCE

Effectiveness is another question.

Traditional longevity and historical medical acceptance do not, on their own, establish clinical benefit, safety, or an appropriate present-day treatment.

Read “hemp” in its historical context. Hemp, cannabis, Indian hemp, bhang, ganja and charas refer to overlapping but differing plants, parts or preparations across these records. Historical names are not dependable guides to modern potency or legal categories. Seed remedies, fiber crops and resin-rich medicines are not interchangeable.

Living chemistry / An aromatic constellation

Beyond THC.
The terpene atlas.

Explore the small aromatic compounds that connect cannabis with citrus, forests, flowers and spice. Select a node to trace its research on mood, inflammation, pain or sleep.

8 terpene profiles · Connections show research topics, not proven benefits or effect sizes.

Aroma is a clue to chemistry. It does not predict a person's mood or a product's medical effect. Concentration, cannabinoids, route, dose and individual biology all matter.

Follow the evidence. Most profiles here describe laboratory or animal findings. Concentrated terpene oils are not instructions for ingestion, inhalation or DIY vape mixing.

Filter by historical strand or search a person, place or preparation. Dates identify the surviving evidence or publication; they do not claim a single origin of cannabis medicine.

13 historical records

8th century BCE

Archaeological evidence · Levant

Burning on an altar at Arad

Chemical residues on the smaller altar at the Judahite shrine at Tel Arad include cannabis compounds. The setting supports an interpretation of ritual burning. It does not establish a treatment, a medical dose, or a regional medical system. [4]

Around 500 BCE

Archaeological evidence · Pamirs

Cannabis at Jirzankal

Residues in wooden braziers from a burial ground in the eastern Pamirs provide evidence of cannabis burning in a funerary setting. This is a distinct line of evidence from a written medical prescription. [5]

5th century BCE

Historical text · Scythian customs

Herodotus describes hemp fumes

Herodotus describes a Scythian practice involving hemp and heated stones. Read the passage as an ancient observer’s account of a cultural practice, with its own context and limitations. [3]

Han-era tradition

Materia medica · China

Hemp enters the Chinese medical record

The Shennong Bencao Jing tradition is attributed to a legendary culture hero, while its compilation is much later. A Chinese medicine collection record distinguishes mafen, the young fruiting inflorescence, from hemp seed. Legendary dates such as 2700 BCE should not be treated as the date of a surviving prescription. [1]

Late 16th century

Materia medica · Li Shizhen

A differentiated botanical medicine

Li Shizhen’s Bencao Gangmu records a developed materia medica tradition. Plant-part distinctions matter: the seed-based remedies in this literature cannot simply be equated with resin-rich intoxicating preparations. [1] [2]

1839 / 1843

Clinical observations · Bengal

South Asian knowledge crosses into British journals

O’Shaughnessy’s 1843 account identifies an earlier 1839 report. He drew on Indian and Persian medical knowledge, collaborators and translators, and described animal experiments and clinical cases involving pain, spasms and convulsions. These observations are an influential historical record, with the limitations of their era. [6] [7]

1850 revision

Official pharmacy · United States

Cannabis appears in the U.S. Pharmacopeia

USP’s own historical account dates cannabis inclusion to the 1850 revision. Some historical references use 1851 as the publication year. Inclusion documents an official pharmaceutical place; it does not establish how often the drug was prescribed or validate every claimed use. [13]

1890

Medical appraisal · Britain

Reynolds weighs therapy and toxicity

J. Russell Reynolds’s Lancet paper discusses therapeutic uses alongside toxic effects. The title itself captures the period’s dual concern: medical promise and the difficulty of obtaining predictable effects. [8]

1893–94

Commission testimony · India

An extensive colonial inquiry

The Indian Hemp Drugs Commission assembled testimony about cultivation, preparations, consumption and perceived effects. Its conclusions distinguished moderate from excessive use. Its evidence is valuable for historical practice, while reflecting colonial institutions, selected witnesses and nineteenth-century methods. [9] [10]

1925 / 1928

Treaty · Signed 1925, in force 1928

International controls take shape

The convention introduced international trade controls for Indian hemp and resin, while restricting cannabis extracts and tinctures to medical and scientific purposes. It was not a single blanket worldwide ban on every use of the plant. [14]

1933

Surviving artifact · Detroit

The bottle on the pharmacy shelf

The National Library of Medicine displays a Parke, Davis & Co. Cannabis Fluid Extract, U.S.P., dated 1933. This authentic object answers a concrete historical question: such preparations were manufactured and bottled by established pharmaceutical firms. [11]

1937

Original statute · United States

The U.S. imposes a tax-and-record system

The Marihuana Tax Act imposed occupational and transfer taxes, registration and records. It included provisions concerning medical practice. Its restrictive effects should be described through the actual law rather than the shorthand that every medical use became illegal overnight. [12]

1942

Pharmaceutical transition · United States

Removal from the U.S. Pharmacopeia

USP records cannabis removal in 1942. Read this alongside changing pharmaceutical practice, formulation problems and legal constraints. No single milestone alone explains the plant’s retreat from official American medicine. [13]

03 / Regional histories

A traveled plant.
An uneven archive.

A global history is not a claim that every culture used the same medicine. The surviving sources differ in date, purpose, language and reliability.

East Asia / materia medica

China: distinguish the plant parts.

The Chinese tradition includes separate descriptions of inflorescences and seeds. Hemp seed appears in a bowel-related medicinal tradition; that record cannot be treated as evidence for every claim made about psychoactive flowers.

The Shennong attribution is legendary, and precise early compilation dates remain a historical question. Li Shizhen is the author associated with Bencao Gangmu. [1] [2]

South Asia / medicine and exchange

India: knowledge before translation.

The nineteenth-century European medical story was built in dialogue with South Asian practices, not from an untouched botanical discovery. O’Shaughnessy acknowledged local medical knowledge and Persian sources in his account.

References to bhanga in early Sanskrit material require careful identification and dating. The linked nineteenth-century clinical and commission records provide firmer ground for the preparations and practices described here. [6] [7] [9]

Levant and Central Asia / archaeology

Ritual evidence has its own value.

Arad’s altar and Jirzankal’s burial braziers extend the material record of cannabis use into antiquity. Their ritual contexts should remain visible.

Herodotus provides another ancient account of hemp fumes. None of these sources alone demonstrates a medical prescription, successful treatment, or continuous therapeutic tradition. [3] [4] [5]

Europe and North America / pharmacy

From imported knowledge to manufactured extracts.

Clinical publications, an official pharmacopoeial place and commercial artifacts show cannabis within parts of nineteenth- and early twentieth-century medicine.

The record is geographically uneven. These sources do not support projecting the same prevalence onto Africa, the Americas before European introduction, or every European herbal tradition. Region-specific evidence is needed for region-specific claims. [8] [11] [13]

04 / Inside the apothecary

What was actually
in the medicine?

A name on a bottle tells only part of the story. Plant part, solvent, preparation, storage and the methods used to assess strength all affected the product.

Historical preparation families · Descriptions, not recipes or dosing instructions
PreparationWhat the record describesWhat to keep distinct
Hemp seed remediesSeed-based materia medica entries, including bowel-related uses in Chinese records. [1]These are not the same material as resin-rich flowers or concentrated extracts.
Bhang, ganja and charasRegional South Asian names associated with differing plant materials and preparations, documented in the commission inquiry. [9]Local terminology, plant parts and preparation practices vary; one label does not define one uniform medicine.
Extracts and tincturesPharmaceutical preparations discussed in nineteenth-century accounts and named in later international controls. [6] [14]Formulas evolved. Historical alcohol percentages or old apothecary units cannot safely be transferred between editions or products.
Commercial fluid extractThe 1933 Parke-Davis bottle provides a surviving example of a labeled U.S.P. preparation. [11]Commercial manufacture is documented; modern cannabinoid assays and consistency cannot be assumed.
Burned plant materialCannabis residues survive in specific ancient ritual settings. [4] [5]Evidence for burning is not automatically evidence for a prescribed inhaled treatment.

What did historical physicians try to treat?

O’Shaughnessy described cases involving pain, spasms and convulsions; Reynolds later reviewed therapeutic claims alongside toxic effects. These records help explain the plant’s appeal to physicians seeking relief for difficult symptoms. [6] [7] [8]

They are historical observations, often without modern controls, standardized formulations or reliable outcome measurement. The exhibit does not translate their claims into present-day prescriptions.

05 / A changing medical system

How does a medicine
leave the shelf?

The historical transition involves pharmaceutical practice, legal controls and public narratives. A single-cause story loses the differences between these forces.

PHARMACEUTICAL

The problem of predictable effects.

Historical physicians confronted variability in preparations and responses. Appraisals such as Reynolds’s placed therapeutic uses beside toxic effects. Pharmacopoeial inclusion and later removal mark changing official practice. [8] [13]

REGULATORY

Restrictions accumulated.

The 1925 treaty regulated trade and medical preparations. The 1937 U.S. act added taxation, registration and records. Their scopes differ; neither should be flattened into a single worldwide prohibition date. [12] [14]

CULTURAL

The label also changed.

NLM’s exhibition places medicinal artifacts alongside later public messaging about marijuana. Studying that shift invites questions about how professional authority, stigma and regulation shape which substances are seen as medicines. [11]

Were the old cannabis medicine bottles real?

Yes. A dated museum artifact establishes that Parke, Davis & Co. sold a Cannabis Fluid Extract, U.S.P., in 1933. It is stronger evidence for a specific manufactured preparation than an unattributed image circulating online. [11]

Was cannabis a universal medicine?

The sources support a wide range of recorded uses across several traditions, with substantial variation. They do not establish use by all cultures, consistent effectiveness across conditions, or universal acceptance among practitioners.

Did the 1937 law instantly prohibit every medical use?

The original statute is a tax, registration and recordkeeping law with medical-practice provisions. Describing its restrictive consequences accurately requires reading those provisions rather than replacing the law with a slogan. [12]

How was the Deep Research document adapted?

This exhibit is a curated adaptation of Cannabis sativa: Global Medical History (Ancient to Early 20th Century), prepared October 23, 2026. Dates, attributions and examples were checked against linked sources. Legendary dates are separated from compilation history; ritual finds are labeled as ritual evidence; USP inclusion uses the 1850 revision; unsupported formulations and historical dosage conversions are omitted. The original research document is preserved.
