What is Ju Pi Zhu Ru Tang?

Ju Pi Zhu Ru Tang is a classical Chinese herbal formula taken for hiccups, nausea and vomiting. It is also known as Tangerine Peel and Bamboo Shavings Decoction. It is listed here as a single entry, but it is a multi-herb formula, not one plant.

The usual mix is tangerine peel (Chen Pi), bamboo shavings (Zhu Ru), ginseng (Ren Shen), licorice (Gan Cao), fresh ginger (Sheng Jiang) and jujube dates (Da Zao). Practitioners pick it for a queasy, hiccupping stomach in someone who is weak or run down after illness.

The evidence in one line: long, respected use in Chinese medicine, but no published human trials of the whole formula that we could identify. Long use in a tradition is not proof that something works.

It contains licorice, which can raise blood pressure and drop potassium (a mineral your heart and muscles need). That makes it a short-course remedy, not a daily tonic, and it clashes with several common medicines.

How does Ju Pi Zhu Ru Tang work?

No one has shown how this formula works in a modern, measurable way. The traditional explanation and the laboratory findings are two separate stories.

In Chinese medicine terms, it is said to settle "rebellious stomach qi" - the upward pushing that shows as hiccups and vomiting. At the same time it is meant to clear mild heat and support a tired digestion.

In the laboratory, ginger and citrus peel show antiemetic (anti-sickness) activity in animal studies. Licorice compounds soothe irritated stomach lining in similar lab models.

Whether those effects add up to anything useful at normal tea-cup doses has not been tested in people. Treat the mechanism as a theory, not a finding.

What forms does Ju Pi Zhu Ru Tang come in?

Most people meet it in one of three forms.

Raw herbs for decoction (a strong tea simmered at home) are the traditional form and the one classical texts describe. Concentrated granules or powders dissolve in hot water and are the most common modern form.

Pills and capsules of the dried extract also exist. Quality and strength vary a lot between makers, and the licorice content is rarely printed on the label.

Where it comes from:

The formula appears in the Jin Gui Yao Lue (Essential Prescriptions of the Golden Cabinet), attributed to Zhang Zhongjing around 200 CE. It has stayed in continuous use in Chinese herbal practice for roughly eighteen centuries and is taught in standard formula textbooks today. It is also used in Japanese Kampo practice, usually under a Japanese reading of the same name.

What does Ju Pi Zhu Ru Tang help with?

• Hiccups, especially persistent ones: This is the formula's signature use and the one classical texts name first. Practitioners use it for hiccups that drag on in someone tired, elderly or post-illness. We found no human trials testing it for hiccups, so the support here is traditional only.
• Nausea and vomiting in someone weak or recovering from illness: Traditionally chosen when sickness comes with fatigue, a dry mouth and slight warmth rather than chills. Ginger, one of its ingredients, does have human trial support for nausea on its own. That does not transfer automatically to the whole formula at the doses used here.
• Belching and reflux-type discomfort: Used traditionally for air and food that seem to push upward after meals. There is no trial evidence for this use. If you have heartburn more than twice a week, get it checked rather than self-treating.
• Poor appetite with a queasy stomach: The ginseng and jujube in the formula are traditionally there to rebuild strength while the other herbs settle the stomach. This is a supportive role, not a treatment for weight loss or malnutrition. Unexplained appetite loss needs a doctor, not a herb.
• Morning sickness (traditional use only, and not advised without supervision): Some classical sources mention it for sickness in pregnancy. We do not recommend it: it contains licorice and ginseng, both of which raise safety questions in pregnancy. Do not use it while pregnant unless a qualified practitioner and your maternity team both agree.

Which foods are rich in Ju Pi Zhu Ru Tang?

1. Dried tangerine peel - used as a flavouring in Chinese braises and soups
2. Fresh ginger - a everyday cooking spice
3. Jujube dates - eaten as a snack and added to soups and porridge
4. Licorice root - used in sweets and herbal teas

Practical Tips:

Eating these foods normally is not the same as taking the formula, but licorice sweets and teas add to your licorice load and count toward the risk.

What are the side effects of Ju Pi Zhu Ru Tang?

• Fluid retention and puffy ankles, from the licorice
• Rising blood pressure, from the licorice
• Low potassium, which can show as muscle weakness, cramps or an odd heartbeat
• Headache
• Trouble sleeping or feeling wired, usually linked to the ginseng
• Loose stools or stomach upset
• Heartburn or a warm feeling after ginger-containing doses
• Allergic reaction, including rash or itching

Good to know:

Most people taking a short course report nothing worse than mild stomach upset. The serious effects come from licorice and build up with dose and time, not with a single cup.

The licorice problem has a name: pseudoaldosteronism (a hormone-like effect that makes your body hold salt and water and lose potassium). It causes high blood pressure, swelling and, in bad cases, heart-rhythm problems.

Stop the formula and get medical advice if you notice swelling, unusual muscle weakness, cramps or a fluttering heartbeat.

How much Ju Pi Zhu Ru Tang should you take?

• Recommended daily: No dose has been established by human trials. What follows is traditional practice, not a tested amount. A typical decoction uses roughly: tangerine peel 9-12 g, bamboo shavings 9-12 g, ginseng 3-6 g, licorice 3-6 g, fresh ginger 9 g and five jujube dates. This is simmered and split into two or three servings across one day. Concentrated granules are usually 2-6 g per day in divided doses, depending on the maker. Follow the product label and a practitioner's advice rather than scaling up the raw-herb numbers.
• Best time of day: Traditionally taken warm, split into two or three doses spread through the day. Some practitioners suggest a dose shortly before the time of day your symptoms are usually worst.
• With or without food: Usually taken warm between meals, or shortly before eating if food triggers the nausea. If it upsets your stomach, take it with a little food.
• Time to effect: Traditional accounts describe relief of hiccups or nausea within hours to a couple of days. There is no trial data to confirm any timeframe.
• How long to take it: Keep it short. A few days to about two weeks is the usual traditional course for an acute bout of hiccups or sickness. The licorice in it is the limiting factor. Taking licorice-containing formulas for more than four to six weeks raises the risk of high blood pressure and low potassium. If your symptoms have not clearly improved within about a week, stop and see a doctor rather than continuing.
