What is Jing Jie?

Jing Jie is a dried herb used in Chinese medicine. It is the stem and flower bud of a mint-family plant, Schizonepeta tenuifolia. People take it at the first sign of a cold, and for itchy skin rashes.

It is a single herb, but it is rarely taken alone. A practitioner almost always mixes it with other herbs in a formula. A charred form, called Jing Jie Tan, is used in tradition to slow light bleeding.

Here is the short verdict. Jing Jie has been used for many hundreds of years in one tradition, but good human studies of the herb itself are missing. A long history of use is not proof that something works, and that gap applies to everything on this page.

How does Jing Jie work?

In Chinese medicine, Jing Jie is said to be acrid and slightly warm. The old texts say it opens the surface of the body, makes you sweat a little, and drives out "wind". "Wind" here is a traditional idea, not a germ or a nerve.

In plain terms, healers used it to bring on a light sweat early in a cold. They also used it to help a rash come out and settle down.

Lab and animal work suggests the plant oil may calm swelling and ease itch. That work is early. It does not tell us what a dose does in a person.

What forms does Jing Jie come in?

Jing Jie comes in a few basic forms. The most common is the plain dried herb, cut for brewing as a tea.

You may also see the herb as a granule or powder that you stir into hot water. Bottled tinctures and capsules exist, but they are less common in Chinese practice.

The charred form, Jing Jie Tan, is the same herb toasted until dark. It is used for a different purpose and should not be swapped for the plain herb.

Where it comes from:

Jing Jie appears in Chinese herbal writing from at least the Tang era, over a thousand years ago. It was later listed in the Ming-era Ben Cao Gang Mu.

It is a staple of Chinese herbal practice, best known in the classic formula Jing Fang Bai Du San. It is not part of Western herbal tradition or Ayurveda.

What does Jing Jie help with?

• Early common cold with chills: This is the main traditional use. Herbalists give it in the first day or two, when you feel chilly, achy and stiff in the neck. There are no good human trials of Jing Jie alone for colds, so treat this as tradition only.
• Itchy skin rashes, such as hives: Chinese practice uses Jing Jie for red, itchy skin that moves around the body. Lab and animal studies hint that the plant may damp down itch and swelling. That work has not been repeated in proper human trials of this herb.
• Measles rash that is slow to come out: Old texts use Jing Jie to help a measles rash surface. This is a historical use only. Measles is a serious illness today, and you should see a doctor rather than treat it with herbs.
• Sore throat at the start of a cold: Jing Jie is often paired with other herbs for a scratchy throat in a new cold. The support is traditional. No human trial has tested the single herb for throat pain.
• Light bleeding (charred form): The charred form, Jing Jie Tan, is used in tradition for light bleeding, such as blood in the stool or heavy periods. We found no human trials testing this. Any bleeding that is new, heavy or unexplained needs a doctor, not a herb.

Which foods are rich in Jing Jie?

1. Not found in foods: Jing Jie is a medicinal herb, not a kitchen ingredient

Practical Tips:

Do not confuse it with culinary mint or catnip, which are different plants.

What are the side effects of Jing Jie?

• Light sweating, which is the expected effect
• Feeling too warm or flushed
• Dry mouth or thirst
• Mild stomach upset or nausea
• Dizziness, usually if you sweat a lot
• Skin rash or itching from an allergy to the herb

Good to know:

Side effects are uncommon at normal food-style doses and are usually mild. The most likely problem is sweating too much, which can leave you weak, thirsty and dizzy. Allergy is rare, but it is possible if you react to mint-family plants such as mint, basil or sage.

How much Jing Jie should you take?

• Recommended daily: There is no dose proven by research. Chinese practice most often uses 4.5 to 9 grams of the dried herb per day, brewed as a tea. The charred form is used at about 3 to 9 grams per day. If you use a granule or capsule, follow the label, as strengths differ a lot between makers. Because this herb is nearly always part of a mixed formula, a trained practitioner should set your dose.
• Best time of day: Usually taken warm, twice a day, morning and evening. For a cold, tradition says to take it warm and then rest under a blanket so you sweat lightly.
• With or without food: Best taken between meals, on a fairly empty stomach. If it upsets your stomach, take it with a little food.
• Time to effect: For a fresh cold, tradition expects some change within a day or two. For itchy skin, any benefit would build over one to two weeks. None of these timings come from human trials.
• How long to take it: For a cold, Jing Jie is a short-term herb. Traditional use runs a few days at most, stopping once the chills and aches ease. For itchy skin, practitioners may use it for a week or two, then check how you are doing. Stop and see a doctor if nothing has changed after two weeks.
