Will Berberine Raise Blood Pressure?

Berberine does not raise blood pressure. Some studies suggest it may even lower it.

Berberine, a compound found in plants like Coptis chinensis and Berberis species, has been used in traditional Chinese medicine for thousands of years. Known for its potential benefits in treating cardiovascular diseases, diabetes, and hyperlipidemia, berberine has garnered significant interest. This article explores whether berberine raises blood pressure, drawing from the latest research and clinical studies.

Pharmacological Properties of Berberine

Berberine has multiple pharmacological activities. It lowers blood glucose levels, improves insulin resistance, and reduces hyperlipidemia. According to a study, berberine also shows cardiovascular protective effects. These include antiarrhythmic properties and the ability to lower blood lipids and blood pressure.

Berberine’s ability to affect various bodily functions makes it a subject of interest. Its impact on blood pressure is particularly noteworthy. Researchers have conducted numerous studies to understand this effect better.

Effects on Blood Pressure

Several clinical trials and meta-analyses have examined berberine’s effects on blood pressure. A systematic review by Suadoni et al. in 2021 found insufficient evidence to report significant effects on blood pressure (PMC9614282). Another meta-analysis by Lan et al. in 2015 also found non-significant results for berberine’s impact on blood pressure in type 2 diabetes patients.

However, some studies show promising results. A 2021 meta-analysis of 12 randomized controlled trials (RCTs) indicated that Armolipid Plus, which includes berberine, was not effective in changing systolic and diastolic blood pressure (PMC9614282). Conversely, another study found that berberine combined with amlodipine was not significantly better than amlodipine alone at reducing blood pressure (PubMed).

Specific Findings

  1. Berberine vs. Metformin: Compared to metformin, berberine provided a statistically significant moderate reduction effect on systolic blood pressure (-11.87 mmHg) (PubMed).
  2. Proprietary Nutraceutical: A proprietary nutraceutical containing berberine was significantly effective at reducing blood pressure compared to placebo (-11.80 mmHg systolic and -11.10 mmHg diastolic) (PubMed).
  3. Chunghyul-dan: The herbal extract Chunghyul-dan, which contains berberine, showed a significant beneficial moderate effect on systolic 24-hour ambulatory blood pressure (-7.34 mmHg) in one study, but no effects were detected in another study with a higher dose and longer treatment duration (PubMed).

Limitations and Quality of Evidence

The quality of evidence regarding berberine’s effect on blood pressure is generally low. Many studies suffer from high heterogeneity, lack of trial design details, and outcome reporting bias (PubMed). For example, trials in various meta-analyses have varying dosages (from 0.9 to 1.5 g daily), intervention periods (from 1 month to 2 years), and quality (PMC8401658).

Safety and Adverse Effects

Berberine is generally considered safe. Most trials report no serious adverse events (PMC8401658). However, some studies note digestive complications like constipation, diarrhea, and flatulence. These typically clear up within four weeks.

Berberine’s blood pressure-lowering effects could potentially cause blood pressure to drop too low in some individuals. This can be dangerous. Therefore, monitoring is essential when using berberine, especially for those already on blood pressure medications.

Key Takeaways

  • Berberine does not raise blood pressure.
  • Some studies suggest it may lower blood pressure.
  • Evidence quality is generally low and inconsistent.
  • Berberine is generally safe but can cause digestive issues.
  • Monitoring is essential for those on blood pressure medications.


Berberine does not appear to raise blood pressure. In fact, several studies and meta-analyses suggest that berberine may have a modest blood pressure-lowering effect. This is particularly true when used in combination with other treatments or lifestyle changes. However, the quality of the evidence is generally low, and the results are often inconsistent due to high heterogeneity among studies.

Clinicians should be cautious when recommending berberine for blood pressure management. The limited and inconclusive evidence warrants careful consideration. Patients interested in using berberine should consult their healthcare provider. This ensures it is appropriate for their specific health conditions and helps avoid potential interactions with other medications.
