Goji berries (枸杞) (scientific name: Lycium chinense and Lycium barbarum), aka wolfberries, aka lycium fruit, are known by many people as a superfood. It can nourish the blood, enrich the yin, tonify the kidney and liver, and moisten the lungs. It can also help treat diseases related to thirst such as early-onset diabetes, dizziness, poor vision, and chronic cough. Again, like many Chinese herbs, the goji berries are dried. However, they should still be moist enough to retain a bright, red colour. If they become too dry and start to deteriorate, their red colour will turn dull and look dirty.
In Traditional Chinese Medicine, a main property of goji berries is to nourish the yin of the kidney and that by doing so, the berries will also enrich the yin of the liver.
Goji berries are often used to make herbal tea, in combination with dried Chinese red dates (jujubes) and dried longan. However, they can also be used alone in hot water to make a simple goji berry tea.
