Centaury + Brexanolone
Brexanolone brand name: Zulresso.
We found no known interaction between Centaury and Brexanolone 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.
Centaury and Brexanolone
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 Brexanolone and Centaury 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Centaury at all — not against Brexanolone, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.

From our pharmacist’s overview on the Brexanolone page
“Brexanolone (Zulresso) is an IV infusion for postpartum depression, and it already carries a boxed warning for excessive sedation and sudden loss of consciousness during treatment. That built-in risk is exactly what most of these 79 supplements press on, so treat this list with genuine care.”

About Centaury
What is Centaury?
- Poor appetite
- Indigestion and bloating
- Stimulating digestion (bitter tonic)
- Mild fever (traditional)
- Liver and gallbladder support (traditional)
Centaury is a bitter-tasting herb traditionally used to stimulate appetite and ease mild digestive complaints. Solid human studies are lacking, so its benefits remain largely unproven, and it is best used short-term with guidance from a pharmacist or doctor.
Centaurium erythraea · Gentianaceae · Aerial parts (flowering tops, leaves, and stems) · Tea (infusion), tincture, liquid extract, capsules, and as an ingredient in herbal bitters
An interaction check asks whether these two react with each other — it does not ask whether Centaury is a good idea for someone in your situation. Here is what our Centaury record says about it on its own.
Centaury: dosing
There is no officially established standard dose for centaury. Traditional use generally involves small amounts of the dried herb prepared as a tea or a few drops of tincture taken before meals.Because products differ widely in strength and form, the safest approach is to follow the directions on the product label and not exceed the recommended amount. It is meant for short-term, occasional use rather than long-term daily use.

Brexanolone Is Linked to Lower Levels of One Nutrient
Natural Medicines records Brexanolone as a medicine that can lower these. This is not an interaction with Centaury — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
