Vervain contains over 20 beneficial plant compounds, including iridoid glycosides, flavonoids, and triterpenoids, which may be responsible for its purported benefits.

Some purported benefits include:*

• Calms Nerves and Mood Swings
• Headaches and Pain Relief
• Helps Improve Breastmilk Production
• Stimulated Digestion
• Supports Detoxification
• May possess antitumor effects
• May protect nerve cells

Vervain can be used to improve lactation, calm stress and anxiety, relieve a headache, and support your liver, kidneys, and digestion.*

  How to make your own herbal tea:

• Add 1-3 teaspoons of the dried herb to a heat-proof jar and pour 8-10 oz. of hot water over them.
• Cover the jar and let your tea steep for at least 15 minutes.
• Strain out the herbs and drink 1-3 cups per day. You can drink as needed or 1-2 hours before bedtime to help you relax before going to sleep.
• Blue vervain is bitter, so you may wish to add a little lemon and sweeten with honey before drinking.

Precautions: Vervains are very safe herbs that rarely have adverse side effects but should not usually be taken in large doses. Vervain is not recommended for use during pregnancy because it can stimulate the uterus. Blue vervain may interact with blood pressure medication and hormone therapy. Large doses may cause diarrhea or vomiting
