Kosbee Korean Rehmannia Root is prepared rehmannia — shu di huang (숙지황) — grown in Korea and traditionally steamed and dried again and again until it turns deep black, chewy, and naturally sweet, with no added sugar, dyes, or artificial flavoring. That long preparation is what sets it apart from raw root: it brews into a cup as dark as black coffee, with a deep, molasses-like sweetness and a soft, sticky-chewy slice. Each resealable pouch holds 5.25 oz (150 g). The finest herbs are born from time and care. To make shu di huang, raw rehmannia root is steamed and dried over and over in the traditional Korean way, until a plain root becomes a glossy "black diamond" — dark, dense, and richly sweet. Kosbee honors that same slow, patient method. From Steamed Root to Black Diamond Raw rehmannia is pale and sharp-tasting. Prepared rehmannia is made by steaming and drying it repeatedly — a traditional method sometimes called nine-steam, nine-dry — which deepens the color to glossy black and turns the flavor round and sweet. That craft is exactly what shoppers worry is missing from cheap versions. These slices are genuinely prepared, so you can see the deep-black color and feel the chewy texture for yourself.

How to Use Korean Rehmannia Root For tea, simmer 10 to 20 g of slices in 1 quart (about 1 liter) of water on low heat for at least 1 hour, then strain. On its own it brews into a cup as dark as black coffee, with a soft, natural sweetness. It is also a traditional base for classic herbal blends — for example, simmered with angelica (dang gui), cnidium (chuan xiong), and white peony for the well-known recipe Si Wu Tang (사물탕). The prepared root is rich and dense, so many people simmer it with a few slices of ginger to keep the brew light, or add a piece to bone broths and soups like samgyetang or galbitang for deeper flavor.
