Tartary Buckwheat Chinese Herb

Tartary Buckwheat (Ku Qiao): A Bitter Herb for Digestion, Blood Pressure, and Cholesterol

Introduction

Tartary buckwheat, known as Ku Qiao (苦荞) in Traditional Chinese Medicine (TCM), is a slightly cold, bitter herb and food-medicine that supports digestion, clears heat, and benefits circulation. It is valued both as a grain substitute and a medicinal food for lowering blood pressure, reducing cholesterol, and aiding in metabolic disorders. Rich in flavonoids such as rutin, it is commonly used to strengthen vessels, improve digestion, and prevent damp-heat-related conditions.

What Is Tartary Buckwheat?

Ku Qiao refers to the seed of Fagopyrum tataricum, a species of buckwheat grown in mountainous regions of Asia. In TCM, it is classified as bitter and slightly cold, and it enters the Spleen, Stomach, and Large Intestine meridians. It is considered both a staple food and an herb, supporting digestive health while regulating blood and qi circulation.
