Frequently Asked Questions

What It Actually Is

Goji berries are the dried fruit of Lycium barbarum, a deciduous shrub that grows wild across northern and central China and is now cultivated in Ningxia, Gansu and Xinjiang. The name people in China use is gou qi zi, and it is one of the very few herbs on this site that is eaten as an ordinary food rather than as a medicine, which is a large part of why it is so widely used. What you buy is a small, elongated, translucent red berry, roughly the size of a large raisin but flatter and more fragile. Good quality is bright scarlet and dry enough to snap rather than bend; dull brown, sticky fruit has been stored badly and has usually lost most of what was in it. The seeds are visible through the skin and are bitter, so the fruit is normally eaten whole rather than seeded, in small quantities, and without much fuss.

Where the Description Comes From

Goji appears in the Shennong Bencao Jing, the oldest surviving Chinese materia medica, in the upper class of substances — the same class as ginseng and rehmannia. The Shen Nong classification is not about safety, it is about how strongly the substance is held to act, and an herb in that class was expected to be capable of changing a person rather than adjusting them. The berry also appears in the Bencao Gang Mu, the 16th-century completion of the material, described in essentially the terms used today: it brightens the eyes, strengthens the waist and knees, and nourishes the liver and kidney. That the description has not shifted much in a thousand years tells you something about how stable the tradition is, and also how little it is a scientific claim — it is a consistent description of a consistent experience, not a measured mechanism.

What to Cook It With

An herb on its own does a fraction of what it does in company. These are the pairings the traditional material actually uses, and what each one is doing there.

• Red dates

  The standard combination, and the two almost always appear together. The dates build qi and warm slightly; the goji is neutral and only nourishes. Together they make a soup that is genuinely restorative rather than merely sweet, and the sweetness of one covers the bitterness of the other seed.

• Ginger

  A few slices, not a thumb-sized piece. Ginger moves what would otherwise stagnate, and because goji is sweet and slack, a formula built on it alone tends to sit heavy. Ginger is also what makes the difference between a dessert and a soup.

• Chicken or duck

  The animal protein carries the qi that goji alone cannot build. The classic use is a whole bird simmered for hours, and the goji goes in for the last twenty minutes rather than the first two hours, because long cooking destroys the polysaccharide fraction that the herb is used for.

• Black sesame

  For the same reason goji is used — both are sweet, neutral, liver and kidney nourishing foods, and together they are the standard answer to a person who is tired and wired at the same time.

Using It in a Kitchen

Who It Is For, and Who Should Not Use It

If You Cannot Get It, or Cannot Take It

• Wolfberry

  The same fruit. This is a naming difference, not a substitute, and if a product says wolfberry it is Lycium barbarum unless the label says otherwise.

• Red dates

  Weaker on the eyes and the liver, stronger on qi and blood. If you cannot find goji, dates in a soup will do a good deal of the same work with none of the anticoagulant concern.

• Blueberries or blackcurrants

  If the point is anthocyanin content rather than the traditional use, these are simply better and cheaper. This is the one case on the site where a supermarket fruit is the better answer.

What the Research Does and Does Not Show

The honest summary is that goji has been studied mostly in small trials with inconsistent quality, mostly in people who are not the people taking it casually in soup. There is genuine laboratory and some animal work on goji polysaccharides and on the carotenoid and betaine content, and a reasonable amount of work on antioxidant capacity. There are human trials in exercise tolerance and in some metabolic markers that are interesting and not conclusive. What has not been established is the traditional claim: nobody has shown that eating goji restores liver or kidney function in the sense the classical texts mean it, because those are not physiological categories with measurable endpoints. Trial quality in this herb literature is a genuine problem — the WHO and NCCIH both note that much of the published herbal research is at high risk of bias, usually small, usually single-centre, and rarely registered. If you take one thing from this page, take this: goji is a pleasant, sweet, mild food with a plausible antioxidant story behind it, and it is safe to eat. That is a lower and more reliable claim than the one usually made for it.

Questions This Ingredient Raises

Sources and Further Reading

Every claim on this page falls into one of two groups, and they are sourced differently. Statements about the traditional use of an ingredient are references to the classical and modern literature that describes it, and they are not claims that it works. Statements about research point at the published work, including the work that came back negative. Where a search link appears it goes to the current results for that query rather than to a single paper, so you can see the whole record for the ingredient instead of the most favourable part of it.
