Stachys officinalis
Also known as: Betony, Wood Betony, Bishop's Wort, Stachys officinalis (L.) Trevis., Stachys officinalis
Overview
Stachys officinalis, commonly known as Betony or Wood Betony, is a perennial herb belonging to the Lamiaceae (mint) family, native to temperate regions of Europe and parts of Asia. It has a long history of traditional use in herbal medicine for a variety of ailments, including stress, anxiety, headaches, gastrointestinal disorders, respiratory conditions, skin inflammations, and wound healing. The plant is rich in diverse bioactive phytochemicals, such as diterpenoids, flavonoids, phenolic acids, and essential oils, which are believed to contribute to its therapeutic properties. Research indicates that Stachys officinalis possesses antioxidant, anti-inflammatory, analgesic, antibacterial, and neuroprotective activities. While its ethnomedicinal uses and phytochemical composition are well-documented, the scientific evidence supporting its efficacy in humans is primarily based on preclinical studies (in vitro and in vivo models) and ethnobotanical surveys. High-quality randomized controlled trials are currently limited, indicating a moderate level of research maturity for this herb.
Benefits
Stachys officinalis exhibits several potential benefits, primarily supported by preclinical research. It shows promise for its anxiolytic and neuroprotective effects, aligning with its traditional use for stress and anxiety. While clinical data are sparse, some studies suggest it may influence the central nervous system. The herb also demonstrates significant anti-inflammatory and antioxidant activities, with extracts reducing inflammation markers and exhibiting strong antioxidant capacity in laboratory and animal models. Furthermore, its essential oils and extracts have shown antibacterial activity, particularly against Gram-positive bacteria, with efficacy comparable to other medicinal plants in the genus. Secondary benefits, inferred from traditional use and some pharmacological studies on related species, include potential improvements in gastrointestinal health and support for wound healing. Due to the lack of robust clinical trials, specific population benefits, effect sizes, and the time course of benefits are not well quantified. Most evidence points to general adult populations as potential beneficiaries, but more research is needed to confirm these effects in humans.
How it works
The therapeutic actions of Stachys officinalis are attributed to its rich phytochemical profile, including diterpenoids, flavonoids, and phenolic acids. Its anti-inflammatory effects are likely mediated through the inhibition of pro-inflammatory cytokines and modulation of oxidative stress pathways. The neuroactive properties, which contribute to its traditional use for anxiety, may involve the modulation of GABAergic and serotonergic systems, similar to mechanisms observed in other Lamiaceae species. The antibacterial activity is thought to be due to compounds within its essential oils and extracts that disrupt bacterial cell integrity or metabolic processes. While specific molecular targets are still being elucidated, these compounds interact with various biological pathways within the central nervous system, immune system, and microbial environments. Absorption and bioavailability data are limited, but flavonoids and diterpenoids generally exhibit moderate bioavailability, which can be influenced by the preparation method.
Side effects
Stachys officinalis is traditionally considered safe for use in herbal preparations, with no major toxicity reported in the available literature. Common side effects are not well documented, but mild gastrointestinal discomfort is a possibility. Uncommon side effects, such as allergic reactions, are possible but appear to be rare. There have been no reports of serious adverse events. Specific drug interactions have not been documented; however, caution is advised when combining Stachys officinalis with central nervous system (CNS) depressants due to the potential for additive sedative effects. Due to insufficient evidence, prudence is recommended for pregnant and lactating individuals, as well as for other special populations. Overall, the safety profile appears favorable, but more comprehensive clinical data are needed to fully assess potential risks and interactions.
Dosage
Due to the limited number of clinical trials, the minimum effective dose and optimal dosage ranges for Stachys officinalis have not been definitively established. Traditional herbal preparations vary widely, and standardized extracts are not well defined. The maximum safe dose is currently unknown. Traditionally, the aerial parts of the plant are used to make teas or tinctures, often consumed multiple times daily. While roots contain diterpenoids, they are less commonly used in traditional preparations. The bioavailability of the active compounds can be influenced by the preparation method. There are no identified required cofactors for its efficacy. Users should exercise caution and consult with a healthcare professional, especially given the lack of established clinical dosing guidelines and safety thresholds.
FAQs
Is Stachys officinalis safe for anxiety?
Traditional use suggests anxiolytic effects, but clinical evidence is insufficient to confirm its safety and efficacy for anxiety. Most supporting data come from preclinical studies.
Can it be combined with other supplements?
No specific interactions are documented with other supplements. However, caution is advised when combining it with CNS-active drugs due to potential additive effects.
How soon do effects appear?
The onset of effects is unknown due to a lack of clinical studies. Traditional use suggests variable onset depending on the condition and individual.
Is it effective as an antibacterial?
In vitro studies show antibacterial activity, particularly against Gram-positive bacteria. However, its clinical relevance as an antibacterial agent in humans is currently unclear.
Is it well studied clinically?
No, Stachys officinalis is not well studied clinically. Most research consists of preclinical studies and ethnobotanical surveys. More rigorous human trials are needed.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC7601302/ – This systematic review by Tomou et al. (2020) covered 60 Stachys species, including S. officinalis, identifying 254 chemical compounds and documenting traditional uses. It highlighted pharmacological activities like anti-inflammatory and neuroprotective effects, but noted the significant lack of clinical trials, emphasizing the need for further research despite comprehensive ethnopharmacological and phytochemical data.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC11597018/ – Pashova et al. (2024) conducted a systematic review of 171 studies on the Stachys genus, focusing on its drug discovery potential, particularly for species like S. officinalis known for their diterpenoid content. The review reported antioxidant, analgesic, antibacterial, and CNS effects, but acknowledged that the evidence is predominantly preclinical, with few clinical studies available.
- https://www.frontiersin.org/journals/pharmacology/articles/10.3389/fphar.2020.586548/full – Chassagne et al. (2021) performed a systematic review on plant antibacterials, including Stachys pubescens, which demonstrated low Minimum Inhibitory Concentration (MIC) values against Gram-positive bacteria. While S. officinalis was not specifically highlighted, this meta-analysis of MIC data suggests the genus's potential in antibacterial applications, though species-specific data for S. officinalis remain limited.
