Few ingredients have been treasured for as long — or as widely — as the goji berry (枸杞, Gǒuqǐ). In Traditional Chinese Medicine (TCM), this small red berry has been used for over 2,000 years to nourish the liver and kidneys, brighten the eyes, and support the body's vitality. Today, goji berries are recognised globally as a superfood packed with antioxidants, vitamins, and minerals.
This article covers everything you need to know: the health benefits of goji berries, the recommended daily dosage, potential side effects, and practical recipes to incorporate them into your everyday diet.
What Are Goji Berries?
Goji berries (Lycium barbarum or Lycium chinense) are small, bright red berries native to China and parts of Central Asia. They grow on a shrub and are typically dried before being sold, giving them a chewy texture similar to raisins with a mildly sweet and slightly tangy flavour.
In Chinese, the berry is called 枸杞子 (Gǒuqǐzǐ) — literally "wolfberry fruit". The dried berry is one of the most commonly used herbs in the entire TCM pharmacopoeia, appearing in classic formulas to nourish Yin and support the eyes, liver, and kidneys.
Health Benefits of Goji Berries
1. Rich in Antioxidants
Goji berries contain exceptionally high levels of zeaxanthin, a carotenoid antioxidant linked to eye health, as well as polysaccharides unique to the Lycium plant. These compounds help neutralise free radicals, supporting healthy ageing and reducing oxidative stress at the cellular level.
2. Supports Eye Health
In TCM, goji berries have long been associated with "brightening the eyes". Modern research supports this: regular consumption of goji berries has been shown to increase macular zeaxanthin levels, which may help support long-term eye health and visual clarity.
3. Boosts Immune Function
The unique Lycium barbarum polysaccharides (LBP) found in goji berries have been studied for their immunomodulatory effects — meaning they help regulate and strengthen the immune system. Regular consumption may help support and maintain the body's natural defences.
4. Nourishes the Liver and Kidneys (TCM Perspective)
In TCM, goji berries tonify Liver Yin and Kidney Yin, making them especially valuable for symptoms such as blurred vision, dizziness, lower back aching, and fatigue — all considered signs of deficiency in these organs. They are a key ingredient in classic formulas like Qi Ju Di Huang Wan (杞菊地黄丸).
5. Stabilises Blood Sugar
Several studies suggest that goji berry polysaccharides may help support balanced blood glucose levels and improve insulin sensitivity. As always, consult a healthcare professional before making significant dietary changes.
6. Mood and Energy Support
Goji berries are a source of B vitamins, particularly thiamine (B1) and riboflavin (B2), which play roles in energy metabolism and nervous system function. Some studies report improvements in energy, sleep quality, and mood among regular goji berry consumers.

Recommended Dosage
There is no single universally agreed dose, but common recommendations and traditional usage suggest:
- Dried goji berries (as a food): 20–30 g per day (approximately 2–3 tablespoons), eaten directly or added to food and drinks.
- TCM dried herb (Gǒuqǐzǐ): 6–15 g per day, typically simmered in teas, soups, or congee.
- Goji berry juice or extracts: Follow product-specific instructions; standardised extracts vary widely.
💡 Tip: Start with a small amount (1 tablespoon / ~10 g) and gradually increase. Goji berries are generally very well tolerated, but sensitive individuals may experience mild digestive discomfort at higher quantities.
Who Should Be Cautious?
Goji berries are considered safe for most people when consumed in normal food amounts. However, keep in mind:
- Blood thinners (warfarin): Goji berries may interact with anticoagulant medications. Consult your doctor if you are taking warfarin.
- Diabetes medication: Due to potential blood-sugar-lowering effects, monitor your blood glucose if you are on medication.
- Pregnancy: TCM tradition advises moderation during pregnancy. The compound betaine in goji berries may stimulate the uterus; consult your midwife or doctor.
- Allergies to nightshade plants: Goji belongs to the Solanaceae family. Those with severe nightshade allergies should take care.
