Vervain, when prepared as a warm infusion, has a calming and soothing effect on the nervous system. Due to its extremely bitter taste, it is often blended with more palatable herbs and sweetened with honey. Its healing properties are largely attributed to its bitter and stimulating effects on the liver and other organs, aiding in liver repair and regeneration. Vervain serves as a natural pain reliever, tranquilizer, and expectorant, making it useful for conditions like chronic bronchitis, joint pain, and illnesses associated with chronic pain. It is particularly beneficial when depression is linked to long-term illness.
 
Also known as the "Herb of the Cross," vervain is tied to a legend that it was used to dress Jesus' wounds after his crucifixion. Additionally, it has a storied history in ancient druid traditions, where it was a key ingredient in love potions.
