Goji Berry (Gou Qi Zi)

Overview

Goji berry, Gou Qi Zi, is the fruit of Lycium barbarum, a shrub grown widely in Ningxia, China. Sweet and neutral, it enters the liver, kidney and lung meridians. It is both a medicine and a food, eaten daily by millions of people, usually steeped in tea, soups or congee.

Traditional Uses in TCM

• Nourishing liver and kidney yin: for dizziness, sore lower back and knees, and age-related decline of essence.
• The eyes: goji is the classic remedy for blurred vision, dry tired eyes and poor night sight, often paired with chrysanthemum (Qi Ju Di Huang Wan).
• Gentle essence tonic: for fatigue and early graying, it builds without being cloying or heating.

How to Use

Typical amounts are 6 to 12 grams a day. The simplest way is to eat a small handful of dried berries, or steep a spoonful in warm (not boiling) water and drink both water and berries. Add them to congee, chicken soup, or steep with chrysanthemum flowers for a classic eye-friendly tea. They are mild enough for daily long-term use.

Safety and Cautions

Goji is very safe; it is a common food. People with loose stools or active digestive infection should pause, as its sweetness can be cloying. Because it can interact with warfarin and affect blood sugar, those on such medication should keep intake consistent and inform their doctor. Choose berries that are deep red and dry but not sticky; excessive sulfur fumigation is a known quality issue, so buy from a trusted source.
