Valerian root (Valeriana officinalis) has been valued since classical antiquity as a gentle aid for sleeplessness and nervous tension. Medieval monastic texts preserved and refined these early preparations, while Renaissance pharmacopoeias codified them into formal herbal practice. Modern monographs still list valerian for promoting restful sleep and calm, showing remarkable continuity across two thousand years. The sections that follow trace this enduring history step-by-step, highlighting how ancient decoctions evolved into today’s teas, tinctures and standardized extracts.
Ancient Greece and the “Phu” Herb
The U.S. National Institutes of Health records that valerian was already in routine medical use during the classical period, when Hippocratic physicians referred to the root as phu because of its strong odour. It was prescribed for women’s health complaints and to quiet “an unquiet mind.” (

Greek texts describe macerating the dried root in warm wine or water to produce a nerve-calming draft—a preparation method very close to today’s teas and tinctures. Modern researchers continue to explore the same pathways; see our
science-backed benefits of valerian root article for contemporary data on sleep latency and GABA modulation.
Roman Expansion and Mediterranean Dissemination
Roman medical writers adopted the Greek practice and exported the herb across the empire. Galenic formularies list valerian for insomnia, digestive discomfort, and palpitations—indications that map closely to its present-day use as a mild sedative. (

Archaeobotanical surveys of villa gardens from Hispania to Asia Minor confirm the root’s cultivation alongside other “nervine” species, underscoring its commercial value in ancient herbal markets.

Valerian in Monastic Herbals and “Sleep Drafts”
Benedictine infirmarers catalogued valerian—often under the Anglo-Saxon name setwall—as a chief ingredient in tonics for “night restlessness”. Hildegard of Bingen praised the root for easing “stormy thoughts,” reflecting a shift toward spiritual well-being alongside physical relief. (

Scribes standardised recipes: one typical sleep draft combined grated valerian, warm ale, and honey—an early forerunner of the modern valerian-hops bedtime tea discussed in our comparison of
Valerian Tea vs Extract vs Capsules.
Everyday Preparations in Village Life
Beyond cloisters, country healers boiled the root with garden mint to offset bitterness, then dried the mixture into portable “herb cakes.” This simple preservation mirrors today’s capsule technology, explored in our
complete guide to benefits, uses & safety.
Community records from the 14ᵗʰ-16ᵗʰ centuries cite valerian for headaches, trembling, and convulsions, suggesting broad acceptance well before pharmacopoeias codified dosage. (

Renaissance → Industrial Era: How Printed Herbals and National Pharmacopoeias Standardised Valerian
Print Revolution: Herbals, Dispensatories and the First National Pharmacopoeias
Movable-type printing triggered a surge of vernacular herbals in the 1500s. These books fixed plant names and unified recipes. By 1618, the Pharmacopoeia Londinensis listed Valeriana officinalis as an “official” sedative ingredient, marking one of the earliest state-endorsed monographs for the root. (

Official drug books soon spread across Europe and later North America, ensuring that valerian infusions, powders and macerations followed identical strength and purity rules. This transition from hand-copied manuscripts to regulated formularies is a key reason the herb remained consistently available for sleep and “nervous unrest.” For modern, evidence-based outcomes of these same indications, see our
science-backed benefits of valerian root.
19th-Century Tinctures and the Rise of Patent Sleep Mixtures
Industrial-scale distilleries refined alcohol extraction. Fluid extracts, ammoniated tinctures and concentrated “compound drops” appeared in medical compendia on both sides of the Atlantic. Civil-War-era formularies documented doses ranging from ½ to 4 fluidrachms, taken up to four times daily for hysteria, restlessness and sleeplessness. (

Manufacturers promoted these ready-to-use liquids as faster and more palatable than traditional teas. Yet official texts still required the crude root to meet pharmacopoeial identity and strength tests, underscoring continuity between folk practice and industrial medicine.

Late-Industrial Quality Controls Set the Stage for Modern Research
Toward the end of the 19th century, European and United States pharmacopeias began assaying valerenic acids and related sesquiterpenes as marker compounds. These chemical benchmarks provided the analytical framework that 20th-century laboratories later used to link valerian with GABA-modulating activity. (
ods.od.nih.gov)
Standardisation also clarified dosing. Most texts converged on 2–3 g of dried root per day or the tincture equivalent. Those figures remain in contemporary guidelines and form the basis of the dosage ranges summarised in our Valerian Root Dosage Guide.
20ᵗʰ-Century Science Meets Tradition: Laboratory Bench to Controlled Trials
Isolation of Valerenic Acids Provided a Reliable Chemical Signature
Investigators separated valerenic acid, acetoxyvalerenic acid and hydrovalerenic acid from dried root extracts in the mid-20ᵗʰ century. These sesquiterpenes were adopted as quantitative markers for authenticity and strength.(

The ability to track these compounds allowed pharmacologists to compare historical teas with modern tinctures and capsules, setting the stage for dose-controlled research.
GABAergic Modulation Explains Traditional Calming Effects
Controlled Trials Reported Shorter Sleep Latency and Reduced Anxiety
A double-blind study in 1982 found that 400 mg of aqueous valerian extract reduced subjective sleep latency and improved perceived sleep quality without next-day grogginess.(

Subsequent meta-analysis of more than 1,300 participants supported modest benefits, though authors called for larger, methodologically robust trials.(

Global Monographs Standardised Quality and Dosage Ranges
The World Health Organization and multiple pharmacopoeias now list valerian root monographs that specify minimum valerenic-acid content and acceptable daily intakes (2–3 g dried root or equivalent extract).(

Modern Perspectives — Why Historical Uses Still Matter
Continuity of Core Benefits: Sleep, Calm and Gentle Muscle Relaxation
Current monographs from the World Health Organization and the European Medicines Agency still list Valeriana officinalis for relief of mild nervous tension and for improving sleep latency.

Ancient Decoction vs Today’s Tea, Dry Extract and Capsule Forms
Medieval “sleep drafts” steeped 2–3 g of grated root in ale or water. Modern pharmacopoeias set the same crude-root weight as the baseline adult dose but allow delivery by:
|
Preparation
|
Typical Dose
|
Quality Standard
|
|
Water infusion (“herbal tea”)
|
2-3 g root, 10 min steep
|
WHO monograph, EMA
|
|
Dry ethanol extract (standardised ≥ 0.4 % valerenic acids)
|
300-600 mg
|
EMA Herbal Medicinal Product
|
|
Soft-gel or powder capsule
|
Equivalent to 2-3 g root
|
USP, PhEur
|
Laboratory assays verify that dry extracts preserve valerenic-acid content better than prolonged boiling, explaining their growing share of the market.(
