Tree Turmeric and Eplerenone

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Eplerenone

Eplerenone falls under ANTIHYPERTENSIVE DRUGS — the group Tree Turmeric interacts with.

Theoretically, taking tree turmeric along with antihypertensive drugs might have additive effects and increase the risk of hypotension.
Animal research suggests that berberine, a constituent of tree turmeric, can have hypotensive effects. Also, a meta-analysis of clinical research suggests that taking berberine in combination with amlodipine (Norvasc) can lower systolic and diastolic blood pressure when compared with taking amlodipine alone.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: tree turmeric (its active ingredient berberine) seems to gently lower blood pressure on its own. Since you take eplerenone to bring your blood pressure down too, pairing the two could push it lower than you want. That might leave you feeling dizzy, lightheaded, or tired, especially when you stand up quickly.

I want to be honest about the strength of the evidence here. This concern comes mostly from animal studies, with some human data on berberine plus a different blood pressure pill. It's a possible, theoretical interaction, not a guaranteed one. If you'd like to try tree turmeric, check with your pharmacist or doctor first and keep an eye on your blood pressure readings at home.

About Eplerenone

What Is Eplerenone Used For?

Brand name: Inspra

Eplerenone treats two conditions. First, it is used to lower high blood pressure (hypertension) in adults. Lowering blood pressure reduces the risk of stroke and heart attack. It can be used alone or alongside other blood pressure medicines.

Second, eplerenone is used to improve survival in stable adults who have heart failure with reduced ejection fraction (HFrEF) — meaning the heart pumps less blood than normal — following an acute myocardial infarction (heart attack).
