Medicinal Properties and Health Benefits

Verbena officinalis has been traditionally used for its calming and anti-inflammatory properties, offering benefits to the nervous, respiratory, and circulatory systems.

It is known to alleviate symptoms of anxiety and insomnia by promoting relaxation and balancing mood, making it a valuable herb for stress-related disorders. Compared to similar herbs like valerian root or passionflower, verbena officinalis is often noted for its more subtle and longer-lasting calming effects, with a potentially higher potency in reducing mild to moderate anxiety. Its anti-inflammatory properties also support respiratory health, helping to ease conditions such as bronchitis and asthma by reducing mucus production and soothing airway irritation.

Additionally, verbena officinalis may support cardiovascular health by improving blood circulation and lowering blood pressure, setting it apart from other herbs that focus more on specific systems rather than offering a broader range of therapeutic benefits.

Forms, Preparation and Usage

Verbena officinalis has been traditionally used for its medicinal properties, and it is available in various forms including fresh plant, dried tincture, powder, essential oil, and capsule.

The most common preparation methods involve making a tea by steeping the dried herb in hot water, creating a decoction by boiling the plant parts, or using an infusion for specific applications. For topical use, the essential oil can be diluted with a carrier oil and applied to the skin, while the powder can be used in poultices or as a supplement. The recommended dosage for adults is typically 1-2 grams of dried herb per cup of water for tea, and it should not exceed three cups per day.

Children should only use verbena officinalis under medical supervision, and treatment should be short-term and conservative, generally not exceeding two weeks without professional guidance.

Safety, Side Effects and Contraindications

Verbena officinalis can be used as a medicinal plant for its calming and anti-inflammatory properties, but it should be used with caution due to its potential side effects and interactions.

Common side effects may include gastrointestinal upset, drowsiness, and in some cases, allergic reactions. It may interact with certain medications, such as sedatives or antidepressants, potentially increasing their effects or causing adverse reactions. Pregnant and breastfeeding women should avoid verbena officinalis due to insufficient safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is advisable to consult a qualified healthcare professional, start with low doses, and monitor for any adverse effects.

Growing, Harvesting and Storage

Verbena officinalis grows best in well-drained, loamy soil with a slightly acidic to neutral pH, thriving in full sun to partial shade, though it prefers full sun for optimal flowering.

It requires regular watering during its growing season, but it is drought-tolerant once established, making it suitable for xeriscaping. To ensure healthy growth, it should be pruned regularly to encourage branching and prevent legginess, and it benefits from occasional fertilization in early spring. The best time to harvest verbena officinalis is during the flowering stage, typically in late summer to early fall, using sharp scissors to cut the flower spikes just above the leaves to preserve the plant for future blooms.

For maximum potency, the harvested plant should be dried in a cool, shaded area with good air circulation, then stored in airtight containers in a cool, dark place or refrigerated to maintain its medicinal properties.
