Pyrroloquinoline Quinone (PQQ) for Anxiety: What the Research Says About This Mitochondrial Compound and Your Mood

If you’ve been searching for a natural approach to calming an anxious mind, lemon verbena — a fragrant, lemon-scented herb native to South America — may be one of the most overlooked options in the entire natural wellness toolkit. While most people know it as a pleasant herbal tea ingredient, an emerging body of research suggests lemon verbena’s primary polyphenol, verbascoside (also called acteoside), may support a calmer stress response, promote antioxidant activity in the brain, and ease the kind of physical tension that so often accompanies daily anxiety.

Lemon verbena (Lippia citriodora) doesn’t get the same attention as lavender, ashwagandha, or lemon balm — but that may be about to change. As research into polyphenol-rich botanicals accelerates, this herb is quietly emerging as a legitimate candidate for nervous system support. If you enjoy exploring the full landscape of evidence-backed botanicals, our Natural Supplements for Anxiety hub is a great place to see how lemon verbena fits alongside the broader conversation.

🌿 What Is Lemon Verbena?

Lippia citriodora, commonly called lemon verbena, is a flowering shrub originally cultivated in Argentina, Chile, and Peru. Spanish colonizers brought it to Europe in the 17th century, where it became popular in herbal medicine traditions for its calming and digestive properties. Today, it’s widely consumed as an herbal infusion and increasingly available as a standardized extract.

The herb’s most studied active compound is verbascoside, a phenylpropanoid glycoside with notable antioxidant, anti-inflammatory, and neuroprotective properties. Secondary compounds include flavonoids like luteolin and apigenin — both of which have independent research trails connecting them to nervous system modulation. (We’ve previously explored apigenin’s role in anxiety in detail — it’s a fascinating compound in its own right.)

🧠 How Lemon Verbena May Support the Anxious Brain

🔬 Antioxidant Neuroprotection

Chronic anxiety is associated with elevated oxidative stress — a state in which free radicals outpace the body’s antioxidant defenses. Brain tissue is particularly vulnerable to oxidative damage, and emerging research suggests that antioxidant-rich botanicals may help buffer this effect.

Verbascoside is a potent scavenger of reactive oxygen species (ROS). A study published in Food Chemistry identified lemon verbena extract as having exceptionally high ORAC (oxygen radical absorbance capacity) values compared to many commonly cited antioxidant herbs. While antioxidant capacity in a test tube doesn’t automatically translate to brain benefits, the compound’s lipophilic nature — meaning it can cross the blood-brain barrier — makes it a credible candidate for neurological support.

💡 Anti-Inflammatory Pathways and Mood

There is a well-documented relationship between neuroinflammation and mood disturbances. Elevated inflammatory cytokines such as IL-6 and TNF-α have been linked to both anxiety and depression in numerous clinical studies. Verbascoside has shown meaningful anti-inflammatory activity in preclinical research, inhibiting NF-κB signaling — a central pathway in the body’s inflammatory cascade.

A 2016 study in Evidence-Based Complementary and Alternative Medicine found that verbascoside modulated pro-inflammatory markers in animal models, suggesting it may help support a less reactive neurological environment. While human trials specifically focused on anxiety are still limited, this mechanism is consistent with how other polyphenol-rich herbs support mood.

😴 The Sleep-Anxiety Connection

One area where lemon verbena has been more formally studied in humans is sleep quality — and sleep and anxiety are deeply intertwined. Poor sleep elevates cortisol, sharpens threat perception, and dysregulates the HPA (hypothalamic-pituitary-adrenal) axis, essentially priming the brain for anxious reactivity. (For a deeper look at this relationship, see our article on Sleep & Anxiety.)

A double-blind, placebo-controlled clinical trial published in the European Journal of Nutrition examined a standardized combination containing lemon verbena extract in adults reporting sleep disturbances. Participants using the herbal supplement reported significantly improved sleep quality scores compared to placebo, with notable reductions in nighttime awakenings and improvements in morning restfulness. Researchers attributed these effects in part to verbascoside’s capacity to modulate oxidative stress that disrupts normal sleep architecture.

❤️ Muscle Tension and Physical Symptoms of Anxiety

Anxiety doesn’t live only in the mind — it manifests physically through muscle tension, elevated heart rate, and somatic restlessness. Lemon verbena has a well-documented history as a traditional antispasmodic, and modern research has begun to examine whether this traditional use has a biological basis.

A peer-reviewed study in Journal of the International Society of Sports Nutrition found that lemon verbena extract supplementation was associated with reduced markers of oxidative muscle damage and improved post-exercise recovery in active adults. While this study focused on physical performance rather than anxiety, the underlying mechanism — reduced oxidative stress and inflammation in muscle tissue — is directly relevant to the kind of physical tension that accompanies chronic stress and anxiety.

✅ What the Clinical Picture Looks Like Today

To be transparent about where the science stands: most of the strongest mechanistic evidence for lemon verbena and the nervous system comes from preclinical (animal and in vitro) studies. Human clinical trials are emerging but remain limited in number and scale. The most robust human data currently relates to sleep quality, muscle recovery, and general antioxidant biomarker improvement — all of which connect meaningfully to anxiety reduction through secondary pathways.

This is not unusual for botanical compounds. Many well-regarded herbs — including Bacopa monnieri and lemon balm — built their reputations on a combination of traditional use, mechanistic research, and a smaller body of direct clinical trials before larger studies eventually followed. Lemon verbena appears to be on a similar trajectory.

What distinguishes it as particularly promising is the convergence of several supportive mechanisms: strong antioxidant activity, anti-inflammatory action, documented sleep support, and a safety profile built on centuries of traditional use in food and herbal medicine.

🌿 How to Use Lemon Verbena: Forms, Dosage, and Timing

💊 Supplement Forms

Lemon verbena is available in several forms:

• Standardized capsule extracts — the most researched form, typically standardized to verbascoside content. This is the preferred form when using it for nervous system or sleep support.
• Herbal tea — widely available and pleasant to drink, though variable in active compound concentration. Useful for mild, everyday calming support.
• Liquid tinctures — convenient and fast-absorbing; look for products standardized to verbascoside percentage.
• Essential oil (topical/aromatic) — used in aromatherapy traditions but not orally; the research on supplementation applies to ingested forms only.

🌙 Dosage and Timing Considerations

Most clinical studies have used doses in the range of 400–600 mg of standardized extract per day, often taken in the evening given its association with sleep quality improvement. As with any botanical supplement, starting at the lower end of the dosage range and assessing your individual response is a sensible approach.

Lemon verbena has a well-established safety record based on its long history as a food herb and herbal tea ingredient. It is generally considered safe for most healthy adults at typical supplement doses. However, as always, consult your healthcare provider if you are pregnant, nursing, taking medications, or managing a health condition before adding any new supplement to your routine.

🫁 How Lemon Verbena Compares to Related Calming Herbs

Lemon verbena shares some chemical similarities with lemon balm (Melissa officinalis) — both are lemon-scented herbs from the same broad botanical family — but they are distinctly different plants with different active compounds and mechanisms. Lemon balm works primarily through rosmarinic acid and GABA pathway modulation, while lemon verbena’s primary action appears to run through verbascoside-driven antioxidant and anti-inflammatory pathways.

This means they are potentially complementary rather than redundant — a distinction worth noting for anyone building a layered natural support protocol. Similarly, lemon verbena’s flavonoid content (including luteolin) overlaps in interesting ways with the mechanisms we’ve explored in our article on apigenin, suggesting these polyphenol-rich botanicals may work synergistically when combined thoughtfully.
