MugwortMugwort is a hardy perennial plant that is native to Europe and Asia but now is also present as a weed in North America (especially the eastern United States). It can grow up to 6ft high, is reddish-brown in color, and prefers full or partial sun in moist to dry soils. Mugwort can be found growing wild along streams, on rocky soil, and in rough terrain. Mugwort is part of the Asteraceae family that also includes: daisies, sunflowers, dandelions, and ragweed.

Mugwort has been used for decades by various cultures for medicinal purposes such as treating:

  • Vomiting
  • Irregular menstrual cycles
  • Anxiety
  • Depression
  • Epilepsy
  • Arthritis
  • Warts
  • Pinworms
  • Breech pregnancy
  • Stomach ulcers
  • Malaria
  • Cancer

Currently, there is little to no scientific evidence that mugwort is effective in treating any medical conditions.

When is mugwort pollen season?

Mugwort pollen is released in the late summer or early fall in North America and year-round in some locations in Europe. Mugwort flowers, also known as flowerheads, are located at the tips of their stem turning from whitish-green buds to yellow or purple-green flowers when bloomed. Once the flowerheads blossom the mugwort pollen is carried by the wind to fertilize its female flowers for reproduction.  Unfortunately, the wind also blows mugwort pollen into your home, on your clothes, and into the air where it will enter your nose, throat, and lungs. For this reason, many people experience allergies to mugwort pollen.
