Some herbal teas are made to wake you up. Goji and longan tea is the opposite — a sweet, gently warming cup that, in Traditional Chinese Medicine (TCM), is associated with nourishing heart blood and calming the spirit. It is the kind of drink you brew when the day has been loud and you want to settle back into yourself.

The pairing is an old one. Goji berries (gou qi zi, 枸杞子) and dried longan (long yan rou, 龙眼肉) are both famous in Chinese food therapy, and they appear together in countless homes and tea shops across China. Each brings something different: goji is known for supporting the liver and kidneys, while longan is traditionally linked to the heart and the quality of sleep.

In this guide, we will look at the TCM properties of both ingredients, how this tea is traditionally prepared, who may enjoy it, and who should be more careful. As always with food therapy, the idea is not to treat a condition but to support the body's natural balance — one warm cup at a time.

What Is Goji and Longan Tea?

Goji and longan tea is a caffeine-free infusion made by steeping dried goji berries and dried longan flesh in hot water, often with a few red dates (hong zao, 红枣) or a touch of rock sugar. The finished cup is naturally sweet, with a honey-like aroma from the longan and a mild, berry-like note from the goji.

Unlike green tea or oolong, there are no tea leaves involved — the "tea" is simply the water that carries the goodness of the fruit. That makes it a gentle choice for the evening, for children, and for anyone who wants to avoid caffeine before bed.

In TCM terms, this brew is classed as a blood-nourishing and spirit-calming tonic. It is traditionally recommended for people who describe themselves as tired but wired: exhausted in the body, yet unable to switch the mind off at night.

TCM Properties of the Ingredients

Goji Berries (枸杞子, Gou Qi Zi)

Goji berries are one of the most famous ingredients in Chinese food therapy. The classic text Shennong Bencao Jing (《神农本草经》) lists them as a superior-grade herb, meaning it was regarded as gentle enough for long-term use. In TCM theory, goji is said to nourish the blood and yin, which is why it is often paired with the idea of healthy eyes, lustrous hair, and steady energy.

Longan (龙眼肉, Long Yan Rou)

Dried longan — the flesh of the longan fruit, also called dragon eye — is traditionally considered one of the sweetest ways to support the heart. Li Shizhen's Bencao Gangmu (《本草纲目》) praises it for nourishing the heart and spleen. In TCM, the heart is not only the organ that pumps blood; it is also considered the residence of the shen (spirit). When heart blood is sufficient, the theory holds, the mind is calmer, memory feels sharper, and sleep comes more easily.

Why They Work as a Pair

Goji nourishes the lower part of the body's energetic map — liver and kidney — while longan works on the upper-middle: heart and spleen. Together, they are traditionally seen as covering both the root and the branch: supporting the deeper stores of blood and yin while gently calming the spirit. This complementary pairing is a common pattern in TCM formula design, where two mild ingredients are combined so their strengths balance each other.

Traditional Uses of This Tea

In Chinese households, goji and longan tea is often brewed during the cooler months or during periods of busy, stressful work. Grandmothers and mothers across China have long simmered it for family members who are studying hard, recovering from illness, or simply not sleeping well.

It is also a traditional drink for the transition seasons — especially autumn, when the weather turns dry and the body is believed to need extra moisture and nourishment. In TCM thinking, dryness can disturb both the lungs and the spirit, and sweet, nourishing drinks are thought to help the body feel less brittle.

The tea is closely related to a well-known TCM formula called Gui Pi Tang (归脾汤), a classical combination that nourishes the heart and spleen. Goji and longan tea can be seen as its gentle, everyday cousin: a simplified, food-grade version that anyone can make at home.

How to Make Goji and Longan Tea

Basic Recipe

Ingredients:

Steps:

  1. Rinse the goji berries and longan briefly under cold water to remove dust.
  2. If using jujube, slice the dates and remove the pits — cutting them helps release their sweetness.
  3. Bring the water to a gentle boil in a small pot or kettle.
  4. Add the goji, longan, and jujube. Reduce to a low simmer and let it steep for 10–15 minutes, until the water turns golden and lightly sweet.
  5. Pour into a cup, leaving the fruit in the pot or straining if you prefer. You can eat the softened fruit — it is traditionally not wasted.
  6. Add rock sugar or honey only if you want extra sweetness. Many people find the longan sweet enough on its own.

    7. Variations

    • With chrysanthemum: Add a few dried chrysanthemum flowers for a cooler, more floral cup — a good choice if you find longan too warming.
    • With astragalus: A small slice of astragalus root adds a gentle, earthy note that, in TCM, is traditionally associated with qi support. Simmer it with the water from the start.
    • Longan egg tea: In some regions, a poached egg is added to the hot, sweet broth to make a nourishing snack traditionally given to new mothers and people recovering from illness.
    • Overnight steep: For a cold version, steep the fruit in warm water, chill overnight, and drink the next day as a mild, refreshing tonic.

    When to Drink

    In TCM food therapy, timing matters. This tea is traditionally enjoyed in the late afternoon or early evening, when its heart-calming qualities may support the winding-down process before sleep. It is generally not recommended as a morning drink on an empty stomach — the natural sweetness and warming nature are thought to sit better after food.

    A common rhythm is 1 cup per day, 3–5 days per week, for a few weeks at a time, then a pause. Food therapy favors cycles rather than constant consumption.

    Who May Benefit (and Who Should Be Careful)

    People Who May Enjoy This Tea

    • Restless sleepers: Those who fall asleep but wake frequently may find the heart-nourishing quality supportive.
    • Tired-but-wired types: People who feel mentally exhausted yet struggle to relax in the evening.
    • After illness or long work: In TCM, recovery periods are when blood and qi are considered depleted, and sweet nourishing foods are traditionally favored.
    • Anyone avoiding caffeine: This brew is naturally caffeine-free.

    Who Should Be More Careful

    • People managing blood sugar: Longan and goji are naturally sweet and contain sugars. Drink in small amounts and monitor how your body responds.
    • People with excess heat signs: Mouth sores, sore throat, red eyes, or irritability may indicate internal heat in TCM terms. The warming nature of longan may not suit this pattern — chrysanthemum tea is a cooler alternative.
    • Pregnant or nursing women: Always check with a healthcare provider before adding herbal tonics to your routine.
    • Anyone on medication: Goji berries can interact with blood-thinning medications in some cases. Discuss with your doctor or pharmacist.

    Frequently Asked Questions

    Can I drink goji and longan tea every day?

    For most people, 1 cup per day, 3–5 days per week, is a reasonable rhythm in TCM food therapy. Because longan is warming and sweet, people who tend to feel hot should drink it less often or in smaller amounts.

    When is the best time to drink it?

    Late afternoon or evening is traditional, when the spirit-calming qualities may be most helpful before sleep. It is usually not recommended first thing in the morning on an empty stomach.

    Who should avoid it?

    People managing blood sugar, those with excess heat symptoms, and pregnant or nursing women should be cautious. Anyone on medication should ask their healthcare provider first.

    Can I add other ingredients?

    Yes — red jujube is a classic addition, chrysanthemum balances the warmth, and astragalus adds a gentle qi-supporting note. Keep additions modest.

    The Bottom Line

    Goji and longan tea is a sweet, simple, caffeine-free tonic with deep roots in Chinese food therapy. In TCM tradition, it nourishes heart blood, supports the spirit, and offers a gentle way to end a busy day. It is not a treatment for any condition, and it will not replace good sleep habits — but as part of a balanced routine, it is a comforting and time-honored way to care for yourself.

    Brew it slowly, drink it warm, and let the sweetness do its quiet work.
