Vervain was first brought from Europe to North America, but it's also abundant in North Africa, China and Japan.3 It's a perennial plant that can reach 1 to 3 feet, and has oblong-shaped leaves and thin, stiff stems.4 The plant produces pink, purple, white or blue flowers that appear during summer.5
Other vervain plant varieties like blue vervain (Verbena hastata), white vervain (Verbena urticifolia), hoary vervain (Verbena stricta)6 or MacDougal verbena (Verbena macdougalii) can be used for herbal remedies, too.7
Many powerful civilizations considered vervain a sacred plant. In fact, Egyptian legend tells us that the vervain plant sprung out when the goddess Isis shed tears to mourn the death of another god, Osiris. Vervain was called "herba sacra" by the Romans, and "hierobotane" or "holy plant" by the Greeks, with these groups both using vervain to brush temple altars. This practice may be a reason why Verbena, vervain's generic name, means "leafy branch."8
Lastly, vervain is connected to a very important chapter in Christian faith. The herb was said to have stopped the bleeding of Jesus' wounds when he was crucified.9 This is probably why vervain is also called the "herb-of-the-cross."10
Vervain may seem visually appealing, but there's definitely more to it than meets the eye. Continue reading to learn more about vervain's positive impacts on your health and the various uses this plant is known for.

Common Uses of Vervain
Vervain leaves and flowers are often collected during mid- to late summer when the plant is in full bloom.26 These can be incorporated into an infusion, tincture, poultice or ointment, which can then be used to help address these conditions:27
Scrofula (a form of tuberculosis28
Traditionally, vervain was used to treat snake bites, nervous disorders, headaches, pain in certain parts of the reproductive system and throat tumors. Mother Earth Living notes that the Chinese utilized vervain as an experimental treatment to potentially combat malaria, blood flukes, coughs and inflammation.30
Vervain may help heal bruises, insect bites, eczema and other skin disorders when used as a poultice or ointment. Some people also believed that chewing the plant's roots helped strengthen teeth and gums. It also has aphrodisiac properties to help stimulate sexual arousal.31
How to Grow Vervain
You may find vervain growing along the edges of roads and in meadows. Planting good vervain requires well-drained soil and full sun.32 Although this plant may also grow under partial sun,33 there's a higher risk for powdery mildew disease and fungi and insect attacks.34
Growing Vervain From Seeds or Cuttings
- Germinating mix
- Garden hose with nozzle
- Rooting medium containing sand and perlite
- Seedling tray
- Pruning shears
• Seed Propagation
- Get some site-appropriate vervain seeds from your local garden or nursery. Refrain from buying seeds from out-of-area or online retailers, since these may not be suitable to conditions at your current location.
- Choose a planting area that's in full sun or appropriate for your specific vervain specie. Check the seed supplier's instructions if available, or consult an expert at your local nursery about the appropriate site for your chosen seeds.
- Combine two parts germinating mix with one part sand. Make enough mixture to cover your planting bed for up to 3 inches deep.
- Till the existing soil, working the germinating material and sand mix with it. Soak your plant bed with water.
- Ensure first that temperatures will fall between 60 and 80 degrees Fahrenheit for the few weeks after planting. Once you're sure, plant the seeds at the particular spacing and depth for your vervain variety, as instructed by your supplier.
- After seeding, lightly water your plant bed. This area should be well-watered until vervain seedlings appear.
• Cutting Propagation
- Take a seedling tray and fill it with rooting medium, ideally a combination of sand and perlite.
- During the early spring, carefully cut 4-inch-long strips from stems of established vervain plants by using pruning shears. Remove leaves that are closest to the cut end, and push the end of each stem into your rooting medium.
- Soak the seedling tray in water, and place it in an area with full sun. Water for the next few weeks until you notice that the roots have been well-established.
- Once the cuttings have taken root, transfer them onto a planting bed that's already been prepared for seed propagation.
- Water the seedlings to maintain soil moisture.
Vervain requires application of additional fertilizer for around a month.37 Do not forget to deadhead, or discard seed heads you may find, as it's a way to ensure that plants remain where they are.38 According to the book "Secrets of Bach Flower Remedies," vervain is best harvested young, typically when it blooms during the middle to late portions of summer.39 Afterward, they should be air-dried and kept in airtight containers.40
How to Make Vervain Tea
A good way to reap some of vervain's health benefits is by making vervain tea. The tea-making process is similar to that of making an infusion:41
Vervain Tea Infusion Recipe
- 1 to 3 teaspoons of dried vervain or 1 to 3 tablespoons of freshly crushed herb per cup of boiling water
- Steep the herbs in boiling water for 20 to 30 minutes.
- Once the drink is finished and poured into a mug, make sure to sip the drink slowly.
Before drinking vervain tea, or any form of vervain, be cautious as it can trigger allergic reactions and side effects.42 If taken in excess, vervain can cause vomiting.43 The book, "The Complete Guide to Herbal Medicines," explains that large doses of vervain may cause problems in your central nervous system and trigger stupor and seizures. Avoid taking vervain if you're using blood thinners like Coumadin, since it can prompt side effects or change the medicine's effect.44
Pregnant women must avoid vervain because it can stimulate uterine contractions. Nursing and pregnant women, and children under 2 years old must avoid this herb as much as possible, while older children must use the correct dosage, which must be based on their weight.
People over 65 years old who want to take vervain must begin with a low dose, and only increase it when necessary.45 Ideally, talk to your doctor regarding the correct amounts of vervain you should be taking, and to see if this herb might be helpful for your condition.
