1. Origin and description

This medicinal herb comes from Curcuma longa L., a perennial plant in the Zingiberaceae family. The medicinal part is the mature rhizome, commonly known as turmeric root. After harvesting, the rhizomes are washed, sliced, and dried.

The dried material has a distinctive yellow-orange color, a mild aromatic scent, and a pungent, slightly bitter taste. Good-quality material should be clean and dry, free from mold or unusual odor, and retain its natural color.

In TCM, this herb is frequently used in formulas related to Qi and Blood circulation, pain caused by stasis, abdominal discomfort, and digestive weakness associated with Qi stagnation.

2. Related names of Turmeric Root

Other names: Khương hoàng, Nghệ vàng thân rễ, Nghệ nhà, turmeric root, yellow turmeric, dried turmeric rhizome.

Scientific name: Rhizoma Curcumae Longae.

Pinyin name: Jiang Huang.

Chinese name: 姜黄.

The name Khương hoàng refers to the prepared rhizome of the yellow turmeric plant used medicinally. Different parts of Curcuma plants may be processed into different TCM herbs, so correct identification is important. Culinary turmeric and Jiang Huang share the same botanical source, but medicinal material is prepared specifically for herbal use.

3. Flavors, Nature – Meridian

According to TCM theory, this herb is Pungent and Bitter in flavor, Warm in nature, and enters the Liver and Spleen Meridians.

The Pungent flavor is associated with promoting the movement of Qi and Blood, while the Bitter flavor helps disperse stagnation. Its Warm nature makes it suitable for patterns involving poor circulation, cold, or stagnation.

Its relationship with the Liver Meridian reflects its traditional role in regulating Qi and Blood. The Spleen Meridian is related to digestion, explaining why this herb may also appear in formulas for abdominal fullness, poor appetite, and digestive discomfort.

9. Difference between Jiang Huang and Yu Jin

Jiang Huang and Yu Jin both come from plants in the Curcuma group, but they are distinct TCM herbs. Jiang Huang primarily uses the rhizome and is described as Pungent, Bitter, and Warm, entering the Liver and Spleen Meridians. Its traditional actions focus on moving Qi, invigorating Blood, dispelling stasis, and relieving pain.

Yu Jin is prepared from a different medicinal portion and is generally considered cooler in nature. In TCM, it is more often associated with clearing heat, relieving constraint, promoting Qi movement, and supporting Gallbladder function. Because their properties and uses differ, the two herbs should not be substituted without professional guidance.
