Korean Achyranthes Root | Cleaned Ox Knee Root (Niu Xi) | 2.8 oz
Kosbee Korean Achyranthes Root is cleaned, dried achyranthes — niu xi (우슬, Achyranthes japonica), the herb known as "ox knee" — grown in Korea, washed free of grit and ready to simmer, with no additives, into a woody, lightly nutty-earthy tea.
This is a fine-rooted herb that traps soil easily, so the most common complaint is that bulk root arrives dusty. Kosbee washes it clean, so there's no scrubbing — just rinse and brew. Each resealable pouch holds 2.8 oz (80 g).
Asian herbal tradition noticed that the swollen nodes along this plant's stem look like the knee of an ox — and named it accordingly, ox knee, or niu xi. It has long been a familiar root in Korean tea. Kosbee washes the fine-rooted herb free of grit and dries it clean, so you can brew the real, ready-to-use root at home.
Cleaned Korean Root, Not Dusty Bulk
Most achyranthes online is bulk Chinese niu xi, and because the herb has so many fine roots, it often arrives dusty and gritty, with worries about what's clinging to it. Kosbee uses Korean-grown root, washed clean under strict handling.
It is a Product of Korea, cleaned and ready to brew, with nothing added.

How to Brew Korean Achyranthes Root
