Drug & supplement interaction

Pu-erh Tea + Rosuvastatin

Rosuvastatin brand names: Crestor, Ezallor.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Pu-erh Tea and Rosuvastatin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Pu-erh Tea and Rosuvastatin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Rosuvastatin and Pu-erh Tea in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Rosuvastatin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rosuvastatin is filed under 4 classifications — including hmg-coa reductase inhibitors ("statins"), hepatotoxic drugs, oral drugs. Pu-erh Tea has documented interactions with 42 drug classes — the most serious being cimetidine (tagamet) (major), ephedrine (major) and adenosine (adenocard) (moderate) — and none of Rosuvastatin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

No Interaction Found — But Data Suggests Pu-erh Tea and Rosuvastatin May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 4 of them are worth acting on rather than waiting out — marked below.

Effects for Rosuvastatin come from the ADVERSE REACTIONS section of its FDA label; effects for Pu-erh Tea come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 223,851 voluntary FDA FAERS reports for Rosuvastatin that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Special populations

Pu-erh Tea in Pregnancy & Breastfeeding

Pregnancy Possibly Safe

When used orally in moderate amounts. Due to the caffeine content of pu-erh tea, intake should be closely monitored during pregnancy to ensure moderate consumption. Fetal blood concentrations of caffeine approximate maternal concentrations. Use of caffeine in pregnancy is controversial; however, moderate consumption has not been associated with clinically important adverse fetal effects. In some studies, consuming caffeine in amounts over 200 mg daily is associated with a significantly increased risk of miscarriage. This increased risk may be most likely to occur in those with genotypes that confer a slow rate of caffeine metabolism. According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, most healthy pregnant adults can safely consume caffeine doses up to 300 mg daily without an increased risk of spontaneous abortion, stillbirth, preterm birth, fetal growth retardation, or congenital malformations. Advise keeping caffeine consumption below 300 mg daily during pregnancy. This is similar to the amount of caffeine found in about 3 cups of tea.

Pregnancy Possibly Unsafe

When used orally in large amounts. Caffeine from pu-erh tea crosses the placenta, producing fetal blood concentrations similar to maternal levels. Consumption of caffeine in amounts over 300 mg daily is associated with a significantly increased risk of miscarriage in some studies. Advise keeping caffeine consumption from all sources below 300 mg daily during pregnancy. This is similar to the amount of caffeine in about 3 cups of tea. High intake of caffeine throughout pregnancy has resulted in symptoms of caffeine withdrawal in newborn infants. High doses of caffeine have also been associated with spontaneous abortion, premature delivery, and low birth weight. In a study that included 2 large cohorts of mother/infant pairs, the first cohort with a median maternal plasma caffeine level of 168.5 ng/mL (range 29.5-650.5 ng/mL) during pregnancy, suggests birth weights and lengths were lower in the 4th quartile of caffeine intake compared with the 1st. By age 7, heights and weights were lower by 1.5 cm and 1.1 kg respectively. In the second cohort of mother/infant pairs with higher maternal pregnancy plasma caffeine levels, median 625.5 ng/mL (range 86.2 to 1994.7 ng/mL), heights at age 8 were 2.2 cm lower, but there was no difference in weights.

Lactation Possibly Safe

When used orally in moderate amounts. Due to the caffeine content of pu-erh tea, caffeine intake should be closely monitored. Breast milk concentrations of caffeine are thought to be approximately 50% of maternal serum concentrations and caffeine peaks in milk approximately 1-2 hours after consumption. POSSIBLY UNSAFE...when used orally in large amounts. Consumption of pu-erh tea might cause irritability and increased bowel activity in nursing infants. Large doses or excessive intake of pu-erh tea should be avoided during lactation.

From our pharmacist’s overview on the Rosuvastatin page

“Rosuvastatin (Crestor, Ezallor) is a statin taken daily for years to lower cholesterol, and its supplement list deserves real scrutiny, not a quick skim. Five of the 63 ingredients on file carry a major rating, headed by grapefruit, which can raise statin blood levels, and by heavy drinking, since beer and wine compound the strain this…”

About Pu-erh Tea

What is Pu-erh Tea?

  • Weight management
  • Cholesterol and heart health
  • Digestion after meals
  • Mental alertness
  • General antioxidant support

Pu-erh tea is a fermented, aged form of tea made from the same plant as green and black tea. It is enjoyed worldwide as a beverage and is sometimes promoted for weight loss, cholesterol, and digestion, but human evidence for these uses is limited. As a normal drink it is generally well tolerated, though it does contain caffeine.

Camellia sinensis · Theaceae · Leaves (fermented/aged) · Loose-leaf tea, compressed tea cakes, tea bags, capsules, extracts

An interaction check asks whether these two react with each other — it does not ask whether Pu-erh Tea is a good idea for someone in your situation. Here is what our Pu-erh Tea record says about it on its own.

Pu-erh Tea: dosing

There is no official or standardized dose of pu-erh tea for any health condition. Most people simply drink it as a brewed beverage, often one to several cups per day.For supplement capsules or extracts, follow the directions on the product label, since strength varies between products.

About Rosuvastatin

What Is Rosuvastatin Used For?

Brand names: Crestor, Ezallor

Rosuvastatin tablets are used alongside diet changes to lower LDL-C ("bad" cholesterol), total cholesterol, and triglycerides (blood fats), and to raise HDL-C ("good" cholesterol) in adults with high cholesterol or mixed cholesterol problems. They are also used in adults with very high triglycerides, a condition called primary dysbetalipoproteinemia (Type III, a genetic fat-metabolism disorder), and to slow the buildup of plaque in arteries (atherosclerosis).

In people without established heart disease but with multiple risk factors, rosuvastatin tablets can reduce the risk of heart attack, stroke, and procedures to open blocked arteries. For children and teens aged 8 and older with heterozygous familial hypercholesterolemia (HeFH, an inherited high-cholesterol condition), the tablet form is used to lower LDL-C after diet alone has not worked. Crestor tablets are also approved to treat homozygous familial hypercholesterolemia (HoFH, a more severe inherited form) in adults and in children aged 7 and older.

Most-Reported Side Effects for Rosuvastatin

Taking Pu-erh Tea and Rosuvastatin Together: Common Questions

Is it safe to take Pu-erh Tea with Rosuvastatin?
We do not list a known interaction between Pu-erh Tea and Rosuvastatin. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Pu-erh Tea and Rosuvastatin have any of the same side effects?
Yes — our sources link each of them separately to 8 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Pu-erh Tea and Rosuvastatin combination checked?
Interactions in our licensed database are recorded against drug classes. Rosuvastatin is filed under 4 classifications, and Pu-erh Tea has documented interactions with 42 drug classes — none of Rosuvastatin's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Pu-erh Tea interact with any other medications?
Yes. Pu-erh Tea has 667 documented drug interactions in our database — Rosuvastatin is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Rosuvastatin interact with any supplements?
Yes. Rosuvastatin has documented interactions with 63 supplements in our database — Pu-erh Tea is not one of them. The Rosuvastatin interaction page linked on this page lists every one, ranked by severity.
