In 1971, a Chinese pharmacologist read a 4th-century Daoist text, found a reference to sweet wormwood for fever, isolated artemisinin, and won the Nobel Prize. The answers to medicine's most urgent questions are sitting in these books.

Methodology
Sources. Plantacopia draws on 23 primary traditions spanning 4,000 years — from the Papyrus Ebers (c.1550 BCE) through the WHO Monographs on Selected Medicinal Plants (1999–2009). All primary source texts are in the public domain.
Translation. Source texts in Classical Chinese, Sanskrit, Classical Greek, Arabic, 17th-century Spanish, Korean, Classical Japanese, Ancient Egyptian, Tibetan, and other languages were translated using Claude (Anthropic) with scholarly source descriptions drawn from established pharmacobotanical literature. All translations are AI-assisted and have not been peer reviewed.
Cross-references. Plant name matching across traditions uses normalized common names and botanical synonyms. A plant appearing in multiple traditions is flagged as a cross-book match.
Copyright. Original source texts (1552–1653) are in the public domain. Translations, cross-source analysis, and database curation © 2026 Noel Wiggins. AI-assisted translation (Claude, Anthropic); human-reviewed and curated.
Limitations. This is a scholarly resource, not medical advice. Do not use plant medicine information from historical sources without consulting a qualified healthcare provider. Many historical remedies are toxic, contraindicated, or ineffective by modern standards.
Cross-Cultural Cannabis Terminology Protocol
Cannabis presents a specific methodological problem that most plants in this corpus don't: its historical names arose from several unrelated linguistic roots, not one term that spread and got translated. Searching only for "cannabis" or "marijuana" -- both comparatively recent words -- would miss nearly the entire historical record. A real cross-cultural evaluation has to search by root family, not by a single English word, and has to hold two further distinctions apart at every step.
Fiber vs. psychoactive use. Most historical cannabis cultivation, especially in East Asia and Europe, was for fiber and seed oil, not intoxication -- plants selectively bred to have almost no psychoactive effect. Many source texts name the fiber-type and drug-type plants differently within the same language (Chinese distinguishes huo ma, fire hemp, from the female flowering heads called ma fen; Sanskrit distinguishes fiber-type śaṇa from psychoactive bhaṅga). Conflating a hemp-rope reference with a drug reference produces a false positive.
Preparation vs. plant. Several major terms name a specific preparation, not the plant itself -- Sanskrit distinguishes gañjā (the resinous flowering tops), charas (hand-rubbed resin), and bhang (a ground leaf-and-seed paste, often drunk as a milk beverage) as three different products of the same plant, each with different potency and different ritual context. Arabic hashish likewise names a resin preparation, not the plant. Search results should be read for which product is being described, not just whether cannabis is mentioned at all.
A deeper trap: some root terms are semantically generic, not cannabis-specific. Testing this search against the actual corpus surfaced something the sources above don't emphasize enough: Arabic ḥashīsh literally just means "dried grass/herb" -- classical Arabic medical texts use "ḥashīshat al-[X]" as a naming convention for various unrelated plants (e.g., ḥashīshat al-zuqāq, "herb of the alley," is a classical name for wild thyme, not cannabis). Southern African dagga has the identical problem -- it names both true cannabis and several Leonotis species with superficially similar leaves. A keyword match on either term is a candidate for review, not a confirmed cannabis reference, and needs the surrounding text read before it's trusted.
Glossary of root terms used in this corpus's search protocol:
| Term | Tradition / language | Notes |
|---|---|---|
| bhaṅga / bhang | Sanskrit / Ayurveda | Leaf-and-seed preparation; named in the Atharvaveda (c. 1500–1000 BCE) as one of five sacred plants |
| gañjā / ganja | Sanskrit → Hindi → later Caribbean | The resinous flowering tops specifically, not the whole plant |
| charas | Sanskrit / Hindi | Hand-rubbed resin, the most concentrated traditional preparation |
| śaṇa | Sanskrit | The fiber-type plant specifically -- excludes this from a drug-use search |
| ḥashīsh / hashish | Arabic | Literally "dry grass/herb"; names a resin preparation, first securely attested 12th c. |
| qunnab | Arabic | The plant itself in classical medical/botanical Arabic (Ibn al-Bayṭār and others) |
| kannabis | Ancient Greek | Root of the modern scientific name; possibly a Scythian/Thracian loanword -- Herodotus describes Scythian vapor-bath use directly |
| 大麻 dà má | Classical & Traditional Chinese | "Great hemp," the general term; named in the Shennong Bencaojing (c. 100 CE) |
| 麻蕡 má fén | Classical & Traditional Chinese | The female flowering heads specifically -- the part associated with visionary effects in the Bencaojing itself |
| dagga | Afrikaans, from Khoekhoe daxa/daxab | South African term; note the same word is also applied to unrelated Leonotis species -- read context carefully |
| insangu / matekwane | Zulu / Sotho | Southern African Bantu-language terms distinct from the Khoekhoe-derived "dagga" |
| kanap / bang | Persian & Avestan | Likely source of both the Germanic "hemp" line and, via Arabic and Greek intermediaries, "cannabis" itself |
Practical effect on search. The "Cannabis Across Traditions" query on the home tab searches this full root-term set together, rather than the single word "cannabis" -- which by itself would return almost nothing from the pre-20th-century corpus, since none of the historical source texts used that Latin name in ordinary usage.
