3 Ways to Use Dokudami

What smells like fish, grows like a weed, and is consumed as tea? You guessed it–dokudami!

If you have ever had iced dokudami (どくだみ, Houttuynia cordata) tea on a sweltering hot Tokyo summer day, you know how refreshing a gulp of it feels as it slides down your throat. You also know that it has a funny smell, somewhere between citrus and cilantro. The story goes that this flowering herb was given its name when people smelled it and wondered what kind of poison it might contain (毒 poison 溜み storing). However, dokudami is far from poisonous, and another name for it is “jūyaku” (十薬, ten medicines). Here are a few of its health properties:

  • Supports immune health
  • Relieves seasonal allergies
  • Good for breakouts, rashes, and eczema
  • Relieves constipation
  • Anti-inflammatory, anti-bacterial, anti-microbial

Some of the dokudami’s names in English are rather unappealing: lizard tail, chameleon plant, fishwort, or fish mint, while others like heart leaf and bishop’s weed are more charming. Fish mint seems to be the common name among plant people. While dokudami tea goes for an extortionate price outside of Japan, you can buy live fish mint plants for a reasonable price. Do note, though, that fish mint is considered a weed and can be quite invasive.

That said, here are three ways to enjoy dokudami.

An old sock makes for a perfect sachet.

It so happens that “dokudami yu” (ドクダミ湯, dokudami bath) is the seasonal bath for the month of June! Here’s how to draw a dokudami bath.

  1. Fill the tub up to waist-level with hot water.
  2. Chop dokudami stems and leaves coarsely
  3. Tie them up in a handkerchief or old (clean) sock to form a simple sachet
  4. Put sachet in the bath
  5. While soaking in the tub, squeeze the dokudami sachet to extract the natural oils
