The blue vervain plant ($Verbena hastata$) has been a staple in traditional herbal medicine for centuries, particularly valued for its calming and nervine properties. Knowing which part of blue vervain is used for tea is the first step to making a soothing infusion. The aerial parts—stems, leaves, and flowers—are used. Harvesting these components at the right time ensures maximum potency. While the roots and seeds have other uses, they are not used for tea.
The Ideal Parts to Harvest for Tea
The parts of the plant that grow above ground are the focus when preparing blue vervain tea. These are known as the 'aerial parts.'
- Leaves: The leaves of the blue vervain plant are a primary component for making tea. They contain many of the beneficial compounds. The flavor is notably bitter, a characteristic of many therapeutic herbs.
- Flowers: The small, purplish-blue flowers that grow in delicate spikes are also used. Harvesting the plant when it is just beginning to flower is often recommended, as this is when the concentration of aromatic oils and beneficial compounds is believed to be at its peak.
- Stems: The upper, more tender parts of the stems are also included in the harvest for tea. They contribute to the bulk of the herb used and contain many of the same compounds found in the leaves.
Best Practices for Harvesting Blue Vervain
To ensure the highest quality tea, follow these best practices for harvesting:
- Timing: Harvest the blue vervain just before or at the start of its flowering period, which typically occurs during the summer months.
- Technique: Use sharp scissors or shears to cut the upper third of the plant, including the flowers, leaves, and smaller stems.
- Timing of Day: For the highest concentration of volatile oils, harvest in the morning after the dew has evaporated but before the sun is at its most intense.
- Drying: Dry the harvested parts quickly. Hanging bunches upside down in a well-ventilated, dark area or using a dehydrator on a low setting are effective methods. Properly dried herbs can be stored for an extended period in an airtight container.
Preparation Methods for Blue Vervain Tea
Blue vervain can be prepared as a tea from either fresh or dried herbs. The preparation method is simple, but the bitter taste may be surprising for first-time drinkers.
- Standard Infusion: Add 1-2 teaspoons of dried blue vervain leaves and flowers to a cup of boiling water. Let it steep for 5-10 minutes, then strain. You can increase the steeping time for a stronger infusion, but this will also intensify the bitterness.
- For Fresh Herbs: If using fresh blue vervain, use a slightly larger amount—approximately 1-3 teaspoons per cup. The same steeping method applies, but the flavor profile may differ slightly.
- Adding Flavor: Many people prefer to mitigate the intense bitterness by adding natural sweeteners like honey or combining the vervain with other, less bitter herbs such as peppermint, lemon balm, or rose.
