How often can I drink red bean and tangerine peel tea?

Traditionally, one to two cups a day, a few days per week, is considered a reasonable rhythm for most people. It is best enjoyed warm, rather than iced, and you can pause on days when you feel very dry or dehydrated.

Can I use fresh tangerine peel instead of dried chen pi?

Fresh tangerine peel is more fragrant but much less drying, and it lacks the aged character of chen pi. In TCM, dried peel that has been aged for at least one year is traditionally preferred for draining dampness and supporting digestion.

Is this tea good for losing weight?

TCM food therapy does not frame this tea as a weight-loss product. However, it is traditionally used to reduce a heavy, bloated feeling and support digestion, which some people find helpful alongside a balanced diet and regular activity.

Can pregnant women drink red bean and tangerine peel tea?

Some TCM sources advise caution with chen pi during early pregnancy, so it is best to consult a qualified healthcare practitioner before drinking this tea while pregnant or nursing.

Red Bean and Tangerine Peel Tea — Draining…

Why Red Bean and Tangerine Peel?

Some of the most beloved drinks in Chinese food therapy come from the simplest pantry staples. Red bean and tangerine peel tea — hong dou chen pi cha (红豆陈皮茶) — is one of them. A handful of small red beans, a few strips of aged tangerine peel, and water are all you need to brew a gently aromatic tea that has been enjoyed for generations to help the body feel lighter and less "stuck."

In Traditional Chinese Medicine (TCM), this pairing is not random. Red bean is traditionally associated with draining dampness through the urinary system, while tangerine peel (chen pi) is known for warming the middle and moving stagnant qi. Together, they are believed to support the spleen's job of transforming fluids — which is why the tea has become a go-to drink for damp, humid seasons and heavy, sluggish days.

If you are new to the idea of dampness, it may help to think of it as the TCM word for that heavy, swollen, foggy feeling — like a wet blanket over the body. Our guide to dampness explained walks through the concept in detail.

TCM Properties of Red Bean (Adzuki Bean)

In TCM food therapy, red bean — the small reddish-brown adzuki bean (Vigna angularis), known as hong dou (红豆) or chi xiao dou (赤小豆) — is classified as:

Nature: neutral to slightly cool
Flavor: sweet and sour
Meridians: heart, small intestine (and, in many sources, spleen and kidney)

Because of these properties, red bean is traditionally used to promote urination, drain dampness, and reduce swelling. Classical texts describe it as a food that helps the body move water downward and out, which is why it appears in so many summer congees, soups, and teas. It is also rich in plant protein, fiber, and B vitamins, making it a nourishing everyday legume beyond its role in TCM theory.

TCM Properties of Tangerine Peel (Chen Pi)

Tangerine peel, or chen pi (陈皮), is not just dried orange skin — it is peel that has been aged, traditionally for at least one to three years. The aging process softens the harshness of the fresh peel and deepens its aromatic, warming character. In TCM, chen pi is classified as:

Nature: warm
Flavor: bitter, pungent, and aromatic
Meridians: spleen and lung

Chen pi is one of the most frequently used qi-regulating ingredients in Chinese kitchens. It is traditionally believed to strengthen the spleen, dry dampness, regulate qi, and transform phlegm. It also helps settle the stomach, which is why a piece of chen pi often appears in rich soups and slow-braised dishes — it lightens them and makes them easier to digest. Our tangerine peel ingredient guide covers its history and uses in more depth.

Why the Combination Works

The genius of this tea is the way the two ingredients support each other. Red bean works on the lower part of the body — draining dampness through urine and easing any swelling or heaviness. Chen pi works in the middle — warming the spleen and stomach, moving qi, and drying dampness at its source. In TCM terms, one drains downward while the other transforms and moves; together they are considered a gentle but effective dampness-draining team.

This is also why the tea feels so different from simply drinking more water when you are bloated. It is not about flushing — it is about supporting the body's own ability to transform fluids, which is a core idea in TCM dampness theory.

The Classic Recipe

This is a forgiving, everyday recipe. You can adjust the amounts to your taste, and the tea works equally well hot or at room temperature.

Ingredients

30 g (about 1/3 cup) dried red beans (adzuki beans)
1–2 strips dried tangerine peel (chen pi, about 3–5 g)
1.2 L (about 5 cups) water
3–4 red dates (jujube), optional
Rock sugar or honey, to taste (optional)

How to Brew

Rinse and soak the beans. Rinse the red beans, then soak them in water for 2–4 hours (or overnight) so they soften and cook more evenly.
Prepare the peel. Rinse the chen pi briefly and soak it in warm water for 10 minutes. You can scrape away the white pith if you find it too bitter.
Simmer. Drain the beans and place them in a pot with the chen pi and 1.2 L of water. Bring to a boil, then lower the heat and simmer gently for 60–90 minutes, until the beans are tender and the liquid has a soft, reddish tint.
Add optional extras. If using red dates, add them in the last 20 minutes. Sweeten with rock sugar or honey only after the tea has cooled slightly.
Strain and serve. Drink the liquid warm. You can also eat the beans — they are soft and nourishing on their own.

Variations

With barley: Swap half the red beans for pearl barley for a stronger dampness-draining brew — similar in spirit to barley tea.
With lotus seeds: Add a handful of lotus seeds to calm the mind and support the spleen.
As a congee: Use less water and cook until the beans fall apart, then enjoy it as a thick, warming red bean porridge.

When to Drink It

This tea is traditionally most appreciated in humid seasons — late spring and early summer, or during rainy spells — when dampness tends to build up. It is also a pleasant after-meal drink when you feel heavy, bloated, or sluggish. In TCM, common signs of dampness include a feeling of heaviness in the limbs, a foggy head, bloating, loose stools, and a sticky coating on the tongue. If that sounds familiar, this tea may be worth trying alongside the seasonal eating advice in our autumn diet guide — or simply as a daily ritual during wet weather.

Precautions

Pregnancy and nursing: Some TCM sources advise caution with chen pi, especially in early pregnancy. Consult a qualified practitioner before drinking this tea.
Dry or yin-deficient constitution: Chen pi is a drying ingredient. People who often feel very dry (thirsty, dry skin, scanty urine) may prefer to use less peel or drink this tea less frequently.
Kidney conditions: Because red bean is traditionally used to promote urination, anyone with kidney disease or on a fluid-restricted diet should check with their doctor first.
Blood sugar concerns: Skip the rock sugar and honey if you are managing blood sugar, or sweeten with a small amount of a suitable alternative.

As with any food therapy, this tea is a complement — not a substitute — for professional medical care. If you have an underlying condition, talk to your healthcare provider before adding it to your routine.
