PU-ERH TEA: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

Pu-erh tea is made by parching and then fermenting the leaves of Camellia sinsensis, the same plant that is used for making green, oolong, and black teas.

Pu-erh tea is mainly made in southwestern China and Taiwan. It contains caffeine, which stimulates the central nervous system, heart, and muscles. Pu-erh tea also contains antioxidants that might help protect the heart and blood vessels.

People use pu-erh tea for improving mental alertness and thinking, high cholesterol, obesity, diabetes, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse pu-erh tea with other caffeine sources, such as coffee, green coffee, black tea, green tea, and oolong tea. These are not the same.

Uses & Effectiveness

We currently have no information for PU-ERH TEA overview.

Side Effects

When taken by mouth: Drinking pu-erh tea in moderate amounts (about 4 cups daily) is possibly safe for most people. Pu-erh tea extract is also possibly safe when used for up to 12 weeks.

Drinking more than 4 cups of pu-erh tea daily is possibly unsafe. Drinking large amounts might cause side effects due to the caffeine content. These side effects can range from mild to serious and include headache and irregular heartbeat.

Special Precautions and Warnings

Pregnancy: Drinking moderate amounts of pu-erh tea during pregnancy is possibly safe. Do not drink more than 3 cups of pu-erh tea daily. This provides about 300 mg of caffeine. Consuming more than this during pregnancy is possibly unsafe and has been linked to an increased risk of miscarriage, increased risk of sudden infant death syndrome (SIDS), and other negative effects, including symptoms of caffeine withdrawal in newborns and lower birth weight.

Breast-feeding: Drinking moderate amounts of pu-erh tea while breast-feeding is possibly safe. But drinking more than 3 cups of pu-erh tea daily is possibly unsafe. The caffeine in pu-erh tea is passed into breastmilk. It might cause irritability and increased bowel movements in nursing infants.

Children: Pu-erh tea is possibly safe in children when consumed in amounts found in food and beverages.

Anxiety disorders: The caffeine in pu-erh tea might make these conditions worse.

Bleeding disorders: Pu-erh tea contains caffeine. Caffeine might slow blood clotting. Use caffeine cautiously if you have a bleeding disorder.

Heart conditions: Pu-erh tea contains caffeine. Caffeine can cause irregular heartbeat in certain people. If you have a heart condition, use caffeine with caution.

Diabetes: Pu-erh tea contains caffeine. Caffeine might affect blood sugar levels. Use caffeine with caution if you have diabetes.

Diarrhea: Pu-erh tea contains caffeine. Caffeine, especially when taken in large amounts, can worsen diarrhea.

Seizures: Pu-erh tea contains caffeine. High doses of caffeine might cause seizures or decrease the effects of drugs used to prevent seizures. If you have ever had a seizure, don't take high doses of caffeine.

Glaucoma: Pu- tea contains caffeine. Caffeine can increase the pressure inside the eye. The increase occurs within 30 minutes and lasts for at least 90 minutes.

High blood pressure: Pu-erh tea contains caffeine. Caffeine might increase blood pressure. But this doesn't seem to happen in people who regularly drink pu-erh tea or other caffeinated products.

Irritable bowel syndrome (IBS): Pu-erh tea contains caffeine. Caffeine, especially when taken in large amounts, might worsen the diarrhea some people have with IBS.

Weak bones (osteoporosis): Drinking pu-erh tea can increase the amount of calcium that is flushed out in the urine. This might weaken bones. If you have osteoporosis, don't drink more than 4 cups of pu-erh tea daily. If you are generally healthy and get enough calcium from your food or supplements, drinking about 3 cups of pu-erh tea daily doesn't seem to increase the risk of getting osteoporosis.

Parkinson disease: The caffeine in pu-erh tea might make Parkinson disease worsen faster when taken with creatine. If you have Parkinson disease and take creatine, use caffeine with caution.

Schizophrenia: The caffeine in pu-erh tea might worsen symptoms of schizophrenia.
