Meadow sage

Meadow Sage (Salvia pratensis L.): A Comprehensive Reference

1. Identity and Botanical Characterization

Nomenclature and Taxonomy

Meadow sage — formally Salvia pratensis L. — is also known as meadow clary, and belongs to the family Lamiaceae. The Latin specific epithet pratensis means "of meadows," referring to its preferred habitat. A recognized botanical synonym is Salvia tenorii Spreng. The species also grows in scrub edges and woodland borders. It is distinct from Salvia officinalis (common sage), Salvia sclarea (clary sage), and Salvia nemorosa (woodland sage), though these species are frequently confused in folk and commercial contexts.

Morphological Description

This herbaceous perennial forms a basal clump 1 to 1.5 m (3.3 to 4.9 ft) tall, with rich green rugose leaves that are slightly ruffled and toothed on the edges. The stems have four edges and are clad in glandular and soft hairs. The leaves are arranged in opposite pairs, with those on the lower part of the stem up to 15 cm (6 in) long, decreasing in size higher up the stem. The inflorescences are dense spikes, with each flower possessing a two-lipped corolla that attracts pollinators such as bees and butterflies.

S. pratensis is distinguishable from the closely related S. nemorosa in having leaves basally disposed, a stem with 1–3 leaf-bearing nodes, pubescence with glandular hairs in the apical portion, and a corolla mostly 20–30 mm long.

Geographic Distribution and Natural Habitat

Salvia pratensis is native to Europe, western Asia, and northern Africa. It is native to Europe and introduced in North America, where it is widely grown as an ornamental. Meadow sage — sometimes called livadna žalfija or wild sage — is the most widespread of all native Salvia species in parts of continental Europe. It grows on meadows and fields, along roadsides, preferring warm, limestone-rich soils, and is readily identified because its tall stems overtop the surrounding grassland vegetation.

Common Preparations and Commercial Forms

The large leaves of S. pratensis were considered much more aromatic than cultivated Salvia officinalis and, for this reason, S. pratensis has been traditionally used for meat cooking. Essentially, meadow sage can be used as a substitute for common sage or as an additive. As a supplement or herbal preparation, the plant is found in the following forms:

• Dried leaf and flowering top tea (infusion or decoction): The leaves and flowers of meadow sage have been traditionally used as tea to treat abdominal pains, skin diseases, and ulcers.
• Hydroethanolic extracts: Dried hydroethanolic extracts obtained from aerial parts have been used in phytochemical and biological investigations of the species.
• Essential oil: Obtained by hydrodistillation of aerial parts, though yields are low (see Section 3).
• Methanol extracts (aerial part and root): Used in laboratory research for phenolic profiling and bioactivity evaluation.

Many wild-growing Salvia species, including S. pratensis, are sometimes used in traditional medicine of different nations instead of sage, or as an adulteration, because of the very similar surface and shape of leaves. This overlap in vernacular naming and commercial supply creates risk of substitution and misidentification.

2. Traditional and Historical Use

European Folk Medicine: Western and Central Europe

In Western Europe and the Balkans, S. pratensis shows versatile applications in folk medicine, being a remedy for wounds and eye-related, digestive, and oral issues (sore throat, toothache, gingivitis, aphthae), as well as for feet pain and weakness. The leaves and flowers were traditionally prepared as tea to treat abdominal pains, skin diseases, and ulcers.

Although S. pratensis is not especially noted for its medicinal properties relative to S. officinalis, the common name "Meadow Clary" is indicative of its traditional use as a treatment for eye maladies; the mucilage from wetted seeds was used to rinse eyes. The name of the plant "clary" is derived from "clear-eye," and the plant seeds were historically ground to a paste and used to clear irritations in the eye.

Culinary History

The use of S. pratensis in cookery reaches ancient times. The large leaves were considered much more aromatic than cultivated Salvia officinalis and, for this reason, S. pratensis has been traditionally used for meat cooking.

Oral and Throat Applications

The seeds were used in the past to remove particles from eyes and to reduce inflammation or redness. The plant was also used as a gargle for sore throats, and to clean teeth.

Mediterranean and Balkan Ethnobotanical Context

In Western Europe and the Balkans, S. pratensis shows versatile applications, being a remedy for wounds and eye-related, digestion, and oral issues (sore throat, toothache, gingivitis, aphthae), as well as for feet pain and weakness. Ethnobotanical scholarship documents citations in Romanian (Butură, 1979), Italian (Leporatti et al., 1985; Vitalini et al., 2013, 2015), and British (Moughan et al., 2021) sources, demonstrating that the plant's folk medical use was distributed across a broad geographic and cultural range in Europe.

Several Salvia species, commonly known as sage plants, are an integral part of various culinary and folklore preparations for the perceived wide range of effects from organoleptic to psychological. Within this broader genus context, S. pratensis occupies a specifically European niche distinct from the more globally documented S. officinalis.

3. Key Constituents and Active Compounds

Phenolic Acids

Existing phytochemical studies have reported the presence of phenolic acids — including rosmarinic acid, methylrosmarinate, caffeic acid, salvianolic acid A, B and H, carnosic acid, hydroxybenzoic acid, and caffeoylthreonic acid — as well as flavonoids (luteolin, apigenin, cirsimaritin, genkwanin), diterpenoids (rosmadial, rosmanol III, abietane diterpenes), triterpenoids, fatty acids, sugars, and organic acids in the aerial parts and roots of the plant.

Rosmarinic acid is the dominant phenolic compound. Analyzed S. pratensis extracts showed that rosmarinic acid is the dominant phenolic compound, with significant amounts of caffeic acid and salvianolic acid A and B. The root extract was particularly rich in rosmarinic acid (11,065.56 µg/g) and caffeic acid (509.00 µg/g), as well as salvianolic acid A (519.22 µg/g) and B (291.60 µg/g), as quantified by UHPLC-DAD/(−)HESI-MS/MS analysis.

HPLC–PDA analysis revealed distinct phenolic acid profiles; in particular, S. pratensis contained greater amounts of hydroxycinnamic acids such as caffeic, p-coumaric, and ferulic acids. Furthermore, salvianolic acid H was annotated specifically in S. pratensis, while caffeoylthreonic acid was distributed specifically in S. nemorosa and S. pratensis.

Flavonoids

Identified flavonoids include luteolin, apigenin, cirsimaritin, genkwanin, and their derivatives. Total flavonoid content in Salvia leaves, including S. pratensis, ranges from 0.37–0.90%.

Essential Oil Composition

The quantity of essential oil extracted from S. pratensis is quite low, approximately 0.073% in air-dried inflorescences. A total of 42 components were identified in this essential oil; the sesquiterpene hydrocarbons represented the major chemical group (50%). The dominant compound was thymol (30%), followed by caryophyllene (25–28%) and p-cymene (9%).

The major compound in the essential oil of S. pratensis identified in a separate study was E-caryophyllene (26.4%). GC–MS analysis of essential oil from aerial parts showed that S. pratensis exhibited a linalool-rich profile accompanied by sesquiterpene derivatives. The variability in dominant compounds across published studies likely reflects differences in geographic origin, harvesting time, and extraction method.

Total Phenolic Content

The total phenolic content was higher in S. pratensis (79.22 mg GAE/g dry extract) than in S. sclarea (52.50 mg GAE/g). The choice of extraction method significantly influenced the concentration of phenolic compounds in the extracts; extracts obtained using the Soxhlet apparatus, particularly those utilizing higher ethanol concentrations (30% and 70%), exhibited elevated levels of total phenolic content, total flavonoid content, and rosmarinic acid.

Terpene and Diterpene Content

Monoterpenes, triterpenoids, and flavonoids are characteristic compounds found in the aerial part of Salvia species, while diterpenoids and phenolic acids are found in roots. In S. pratensis specifically, abietane-type diterpenoids including rosmadial and rosmanol III have been chemically characterized in phytochemical profiling studies.

4. Established Mechanisms of Action

Antioxidant Activity

The primary mechanism underlying S. pratensis's antioxidant potential is the radical-scavenging capacity of its polyphenolic constituents, particularly rosmarinic acid. Rosmarinic acid has antimicrobial, antioxidant, and anti-inflammatory activity, contributing to its effects in medical conditions because of its significant ability to limit inflammatory and toxic processes. Rosmarinic acid modulates multiple signaling pathways mediated by PPARγ, AMPK, NRF2, and/or NF-κB in cells.

Anti-inflammatory Mechanisms

Nuclear factor-κB (NF-κB) and tumor necrosis factor (TNF)-α are agents at the top of the inflammatory cascade that activate T cells, and rosmarinic acid inhibits their expression. Rosmarinic acid's effects on T cells and the release of inflammatory cytokines benefit chronic inflammatory disease, acute and chronic allergic phenomena, and autoimmune diseases.

Several studies reported that rosmarinic acid exerted anti-inflammatory effects by inhibiting complement activation and cyclooxygenase (COX) activity. The inhibition of COX-2 expression by rosmarinic acid has been mechanistically linked to antagonism of activator protein-1 (AP-1)-dependent gene transcription, as demonstrated in vitro.

Antimicrobial Mechanisms

The binding affinity of rosmarinic acid was found to be very strong against both dihydrofolate reductase (DHFR) and dihydropteroate synthase (DHPS), which are key enzymes in bacterial folate biosynthesis. These findings suggest that rosmarinic acid may play a central role in observed antibacterial activity. Other compounds such as caffeic acid, fumaric acid, and salvianolic acid B also exhibit favorable binding affinities and interactions, supporting their potential as multi-target inhibitors.

5. Scientific Evidence by Health Area

5.1 Antioxidant Activity

Evidence level: In vitro (preclinical); no human trials specific to S. pratensis.

In a 2026 comparative study (published in Plants, PMC), hydroethanolic extracts of S. pratensis and S. sclarea showed strong antioxidant activity; DPPH IC₅₀ values were 3.16 µg/mL for S. pratensis and 6.67 µg/mL for S. sclarea, indicating S. pratensis was the stronger radical scavenger in this assay.

In another study, S. pratensis extracts demonstrated considerable antioxidant activity, particularly radical scavenger activity with IC₅₀ values ranging between 24 and 90 µg/mL. S. pratensis extracts also showed high DNA protection alongside antioxidant potential.

In a comparative study of seven wild-growing Mediterranean Salvia species, all studied ethanolic leaf extracts including S. pratensis exhibited significant DPPH and nitric oxide (NO) radical scavenging ability, lipid peroxidation inhibition, and reducing power, as well as moderate iron-chelating properties. Rosmarinic acid was the predominant hydroxycinnamic acid in all studied sage plants, ranging from 9,400 to 38,800 µg/g.

All antioxidant data for S. pratensis currently derive from in vitro assay systems (DPPH, ABTS, FRAP). No controlled human clinical trials on the antioxidant effects of S. pratensis specifically have been published in the indexed literature.

5.2 Antimicrobial Activity

Evidence level: In vitro only; no clinical trials specific to S. pratensis.

Extracts of S. pratensis showed moderate broad-spectrum antimicrobial activity, with minimum inhibitory concentration (MIC) values of 312.5–2,500 µg/mL against tested strains. S. pratensis root extract possessed higher antimicrobial and cytotoxic activity compared to the aerial part extract.

Some of the essential oils and phenolic compounds of plants belonging to the Salvia genus have shown excellent antimicrobial activity as well as antioxidant capacity, and consequently, the corresponding extracts have been widely used to stabilize fat and fat-containing foods.

It is important to note that MIC values in the 312.5–2,500 µg/mL range are considered moderate in the context of in vitro antimicrobial research, and translation of these findings to clinical use requires further investigation.

5.3 Cytotoxic and Antiproliferative Activity

Evidence level: In vitro only.

In vitro assays on HEK 293 (human embryonic kidney) and HaCaT (human keratinocyte) cells confirmed low cytotoxicity of S. pratensis extracts, with no evidence of membrane damage or pro-inflammatory effects. More specifically, in HEK 293 cells, S. pratensis showed minimal effects on cell viability even at the highest tested concentrations. In HaCaT keratinocytes, the extract produced no significant changes in viability.

These biocompatibility data are preliminary and derived from transformed or non-malignant cell lines. No human data on cytotoxicity or antiproliferative activity of S. pratensis preparations exist in the indexed literature.

5.4 DNA Protection

Evidence level: In vitro only.

S. pratensis extracts showed high DNA protection potential in in vitro assay systems. The mechanism is likely attributable to the radical-scavenging and anti-oxidative properties of rosmarinic acid and associated polyphenols. No human or animal in vivo studies have directly examined DNA-protective effects of S. pratensis.

5.5 Digestive and Gastrointestinal Use

Evidence level: Traditional use only; no controlled clinical evidence.

The leaves and flowers of meadow sage have been traditionally used as tea to treat abdominal pains. In Western Europe and the Balkans, S. pratensis was a folk remedy for digestive complaints. No clinical trials or animal studies have systematically examined the gastrointestinal effects of S. pratensis preparations.

5.6 Oral Health (Sore Throat, Gingivitis, Toothache)

Evidence level: Traditional use only; no controlled clinical evidence.

In Western Europe and the Balkans, S. pratensis was used as a remedy for oral issues including sore throat, toothache, gingivitis, and aphthae. The plant was also used as a gargle for sore throats and to clean teeth. These traditional uses have not been validated by controlled clinical trials for S. pratensis specifically.

5.7 Wound Healing and Skin Applications

Evidence level: Traditional use; limited in vitro biocompatibility data.

In Western Europe and the Balkans, S. pratensis was recorded as a folk remedy for wounds. The biocompatibility assay data referenced above — showing low cytotoxicity and no pro-inflammatory responses in human keratinocyte (HaCaT) cells — suggests that topical preparations would not be expected to cause cellular irritation, but this cannot be extrapolated to clinical wound-healing efficacy without direct studies.

5.8 Eye Conditions

Evidence level: Historical/ethnobotanical use only.

The plant seeds were historically ground to a paste and used to clear irritations in the eye. The mucilage from wetted seeds was used to rinse eyes, and the word "clary" originates from the term "clear-eye." No modern pharmacological or clinical studies on ocular applications of S. pratensis preparations appear in indexed scientific literature.

5.9 Rosmarinic Acid and Inflammation: Mechanistic Studies

Since rosmarinic acid is the principal bioactive constituent of S. pratensis, mechanistic data on rosmarinic acid from Lamiaceae sources are directly relevant to understanding how meadow sage extracts may act biologically. Rosmarinic acid can remove reactive oxygen species (ROS) and suppress cell activation, epithelial–mesenchymal transition (EMT), and fibrogenic gene expression by inhibiting the stress-induced expression of TGF-β, CTGF, and Wnt and their signaling pathways. These mechanisms have been demonstrated predominantly in in vitro and animal model systems, not in human clinical trials of S. pratensis itself.

5.10 Herbicidal and Agricultural Activity

Extracts of S. pratensis prepared by hot water at two temperatures (60°C and 100°C) and Soxhlet extraction by three different ethanol concentrations (10%, 30%, and 70%) have been investigated for phytotoxic and antioxidant potential. This research direction explores eco-friendly herbicidal applications based on the plant's secondary metabolite content, and is not directly relevant to human dietary supplementation use.

6. Body Systems and Health Areas of Association

Based on the documented traditional uses and in vitro scientific evidence, Salvia pratensis is associated with the following body systems and health areas:

• Gastrointestinal system: Traditionally used as tea for abdominal pains and ulcers.
• Immune and inflammatory system: Studies suggest that plants of the Salvia genus, including S. pratensis, possess antioxidant, anti-inflammatory, antinociceptive, antimicrobial, and immune-stimulating effects.
• Integumentary system (skin and wound healing): Ethnobotanically recorded as a remedy for wounds and skin diseases across Western Europe and the Balkans.
• Oral cavity and throat: Folk remedy for sore throat, toothache, gingivitis, and aphthae.
• Ocular (eye) health: Traditional use via seed mucilage for rinsing and clearing eye irritations.
• Antioxidant defense: Studies suggest Salvia plants possess antioxidant, anti-inflammatory, antinociceptive, anticancer, antimicrobial, antidiabetic, antiangiogenic, hepatoprotective, and cognitive memory-enhancing effects — though for S. pratensis specifically, evidence exists only at the in vitro level for most of these.

7. Dosage Forms and Reported Dosages

No standardized clinical dosage for Salvia pratensis has been established, as no Phase II or Phase III human clinical trials have been conducted with this specific species. The following dosages appear only in traditional or preliminary contexts:

• Herbal infusion (tea): Traditional use calls for 1 tsp (2 g) of dried flowering tops per 200 mL of boiling water, steeped for 5–10 minutes, taken 1–2 cups daily. This dose is reported in one Ayurveda-oriented herbal source; it does not derive from a controlled clinical trial.
• Hydroethanolic (standardized) dry extract: In the comparative phytochemical characterization study, dried hydroethanolic extracts obtained from aerial parts were analysed. Extract concentrations used in cell-based assays ranged from approximately 3.16 µg/mL (DPPH IC₅₀) to upper tested concentrations in cell viability studies; these are laboratory-scale concentrations, not human supplementation doses.
• Soxhlet ethanol extract (30–70%): Extracts obtained using the Soxhlet apparatus, particularly those utilizing higher ethanol concentrations (30% and 70%), exhibited elevated levels of total phenolic content, total flavonoid content, and rosmarinic acid. Again, these are research-scale preparations.
• Gargle preparation: Historically used as a gargle for sore throats — no specific concentration or volume is reported in primary ethnobotanical literature identified.

The absence of clinical trial data means that no safe or effective human dosage can be formally recommended on the basis of current evidence.

8. Safety Considerations

In Vitro Biocompatibility Data

In HEK 293 cells, S. pratensis showed minimal effects on cell viability at all tested concentrations; in HaCaT keratinocytes, the extract produced no significant changes in viability. The absence of increased LDH release and nitric oxide production further indicated that the extracts did not induce detectable membrane damage or pro-inflammatory responses under the tested conditions.

Chemical Contaminants

Chemical safety assessment of S. pratensis aerial parts indicated minimal contamination, with pesticide residues detected only in S. sclarea at levels below regulatory limits, and low concentrations of cadmium and lead in both S. pratensis and S. sclarea samples. This is reassuring for wild-harvested material in the tested populations, but cannot be generalized to all geographic sources.

Bioaccessibility of Rosmarinic Acid

In vitro digestion of S. pratensis extract showed low bioaccessibility of rosmarinic acid. This suggests that the biologically active phenolics may not be efficiently absorbed from the gastrointestinal tract under standard digestive conditions, which would attenuate in vivo effectiveness relative to in vitro assay results.

Risks of Species Confusion and Adulteration

Many Salvia species are an integral part of botanical drug applications, highlighting the need for accurate identification and quality control for consumer safety. Essential oils isolated from 50 specimens of S. pratensis were studied to identify compounds potentially used as adulterants in commercial S. officinalis-based medicines, underscoring the dual concern of S. pratensis both being adulterated with other species and being used to adulterate products intended to contain S. officinalis.

Potential Uterine Effects

Within the broader genus Salvia, certain species with significant thujone content (notably S. officinalis) are contraindicated in pregnancy due to abortifacient and emmenagogic effects. Salvia officinalis oil and extract consumption is contraindicated during pregnancy due to its abortifacient and emmenagogic properties. S. pratensis has a chemically distinct essential oil profile (dominated by sesquiterpenes and linalool rather than thujone or camphor as in S. officinalis), and direct evidence of these effects in S. pratensis has not been established in the indexed scientific literature. Nevertheless, pregnant women are traditionally advised to avoid concentrated preparations of meadow sage pending specific safety data.

Evidence Gaps and Limitations

Salvia pratensis is among the many species of the Salvia genus that have not been sufficiently tested and whose potential use has not been fully exploited. Despite belonging to the same genus, S. pratensis has received considerably less scientific attention compared with cultivated Salvia species. The consequence is that the safety profile for human supplementation use is based almost entirely on in vitro cell studies, traditional use records, and inference from related species — not on dedicated human pharmacokinetic, toxicological, or clinical studies.

9. Position Within the Salvia Genus and Research Context

Numerous Salvia species have significant commercial value on the herbal market and are of great interest to the food and pharmaceutical industry. With wide use in traditional medicine and the inclusion of several species in pharmacopoeias, species from the genus Salvia are known for the broad spectrum of their biological activities. Within this context, S. pratensis is specifically characterized as "neglected" and "underexplored" relative to S. officinalis, S. miltiorrhiza, and S. sclarea in multiple recent phytochemical reviews.

Results from recent comparative studies highlight the significant bioactive potential of the less studied S. pratensis, demonstrating that this wild species represents a promising alternative source of natural antioxidant and antimicrobial compounds comparable to the widely cultivated S. sclarea. However, research to date remains largely confined to in vitro phytochemistry, and clinical translation has not yet occurred. Human pharmacokinetic, toxicological, and efficacy trials are necessary before S. pratensis can be recommended for specific health indications.
