Korean Eucommia Bark | Dried Du Zhong Chunks (Eucommia ulmoides) | 3.5 oz
Kosbee Korean Eucommia Bark is 100% pure dried du zhong (두충, Eucommia ulmoides) from Korea — thick, square-cut bark chunks rather than powder or capsules, with no additives, ready to simmer into a woody, lightly sweet-bitter tea.
Break a piece and you'll see fine white threads stretch inside — the natural sign of real eucommia bark, and an easy way to know you're brewing the genuine root-and-bark, not a mystery powder. Each resealable pouch holds 3.5 oz (100 g).
Across East Asia, the bark of the eucommia tree — du zhong — has been one of the most treasured barks, simmered low and slow into a deep, woody tea. Kosbee selects thick Korean eucommia bark and cuts it into even squares, so you can brew the real, whole bark at home.
Thick Korean Bark, Not Powder or Capsules
Most eucommia in North America is sold as a powder or capsule, often imported from China, with no way to tell if it's even the real bark. Kosbee gives you thick, authentic Korean bark — with the telltale white threads — that you brew yourself.
The bark is famously tough to cut, so Kosbee squares it off into even, ready-to-brew chunks — a Product of Korea with a clear origin.

How to Brew Korean Eucommia Bark
Rinse 0.35 oz (about 10 g) of bark chunks, add to 1.5 quarts (about 1.5 liters) of water, bring to a boil, then simmer on low for 40 minutes to an hour. It has a woody, lightly sweet-bitter flavor.
For a blend, simmer it with Kosbee achyranthes root (uslseul) for a deeper, rounder herbal cup or broth.
The bark is hard and tough, so don't chew it — simmer it for tea, then strain out and discard the chunks.
How to Enjoy It Safely
If you take prescription medication, especially for blood pressure or your heart, talk to your doctor before drinking it regularly.
If you are pregnant or nursing, talk to your doctor before drinking it.
It has a warm, woody character, but if you have a sensitive stomach, start with a weaker brew and enjoy it in moderation.
