Mugwort Leaves

Mugwort Leaves


  • Beginning in the Iron Age, mugwort was used to flavor beverages (including beer before hops). It’s thought the name mugwort is derived from this use (drinks with this plant served in mugs). Wort is an old term for plant.

  • It’s often considered a weed and an invasive plant.
  • The plants attract butterflies and moths.


  • Mugwort was used in Europe to induce abortions, help expel the afterbirth, and regulate the menstrual cycle. Conversely, mugwort was used in China to prevent miscarriage. I suspect they are different mugwort varieties.
  • In traditional Chinese, Japanese, and Korean medicine, Chinese mugwort (Artemisia argyi) is used for moxibustion (a form of heat therapy), and for a large variety of health issues. I mention this because it shows up in a lot of mugwort searches and the plant variety is the distinction.

  1. Hi Holly – fascinating history about the plant and associates of mugwort …I knew some of it – but as it is H day – I'm glad it means happiness and good luck – we all need these now … cheers and have a good week – Hilary


    1. There is even more history and lore on mugwort. I didn't know just how much until I started researching it.

  2. Thanks for clearing up the source of mugwort's common name. I've always wondered how a beautiful name like Artemisia could devolve into mugwort!

  3. I have wormwood in my fridge. Didn't know it was the same thing. Neato.

    1. They are and they aren't in the sense that there are so many varieties.

  4. This is going to sound crazy but I've wanted to grow mugwort ever since I first watched Practical Magic. I love growing unusual herbs, as well as the common ones.

  5. At first I thought this was going to be something about Harry Potter.

    Sounds like a potentially useful plant.

  6. Funny how it ended up with such a name. Thanks for the details. I had no idea!

  7. Interesting folklore on mugworts–thanks for sharing. Does it have anything to do with the inevitable squirrel uprising or the sudden outbreak of werehermitcrabs?

  8. A fascinating post. I do like saying its name. I do wonder how it would taste in beer. One of my friends works at a local brewery, and they're always brainstorming about different things to try in their beers.

  9. That is one freaky-bleaky plant. It's like it does everything and then some. I can't help wonder if JK Rowling used it to come up with the names Hogworts and Muggles. Very cool info. Thanks & have a great Easter!

  10. mugwart is such a great fantasy name! and i'll be tossing some on a firepit if I can find some!

    ps – I added my answer to the "character" question – I had the hardest time wording it, so I'm sure it confused others too!
    Thanks for playing =)

  11. The botanical name has much more oomph to it, like Artemis–goddess of the hunt. 🙂 Like a few other people here, I too thought of Harry Potter when I saw the name. I like the lore of keeping the baddies away.
