Moderate Interaction
Medically reviewed by · Updated September 2026

Interaction report

Tree Turmeric and Temazepam

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Tree Turmeric interacts with whole categories of medication. Temazepam falls into 2 of those categories, so it can interact with Tree Turmeric in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Temazepam

Temazepam falls under CNS DEPRESSANTS — the group Tree Turmeric interacts with.

Theoretically, use of tree turmeric along with CNS depressants might increase the risk of additive therapeutic and adverse effects.
Animal research suggests that berberine, a constituent of tree turmeric, can have sedative effects.
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: temazepam already calms your brain to help you fall asleep, and early research hints that berberine (the active part of tree turmeric) may have its own mild sedative effect. Put them together and the worry is that the two could add up, leaving you groggier than you bargained for. With temazepam, that might look like extra daytime drowsiness, dizziness, slower reactions, or feeling foggy the next morning.

I want to be honest about how shaky this evidence is, though. It comes from lab and animal studies, not real people, so we're talking about a theoretical concern, not something proven. Still, since both can make you sleepy, it's worth a quick chat with your pharmacist or doctor before combining them.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Temazepam also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, tree turmeric might increase the levels and clinical effects of drugs that are substrates of CYP3A4.
In vitro research and preliminary clinical evidence suggest that berberine, a constituent of tree turmeric, moderately inhibits CYP3A4.
Severity Moderate Likelihood Probable Evidence A

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the gist for Restoril (temazepam): your liver uses an enzyme called CYP3A4 to help clear it out. Berberine, the active part of tree turmeric, can mildly slow that enzyme down. When the enzyme works slower, temazepam may hang around a little longer than usual, which could make its effects stronger.

In real terms, that might mean feeling extra drowsy the next morning, groggy, dizzy, or unsteady on your feet. The good news is this concern is mostly theoretical and modest, but since temazepam already makes you sleepy, even a small bump can matter. I wouldn't panic, just don't pair them without checking first. Please talk with your pharmacist or doctor before combining the two.

See Every Supplement That Interacts With Temazepam

This page covers Tree Turmeric only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Temazepam page lists 197 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Grapefruit (major).

By severity: 9 major · 150 moderate · 38 minor.

From our pharmacist’s overview on the Temazepam page

“Alcohol is the interaction I would flag first for anyone taking temazepam (Restoril), a benzodiazepine sleep medicine. Beer and wine both carry major ratings because they layer their own sedation on top of a drug that already depresses the nervous system, and that additive drowsiness runs through 78 of the 197 supplements on file.”

Temazepam capsules — sold as Restoril and under the generic name Temazepam — are indicated for the short-term treatment of insomnia, generally 7 to 10 days. They help people fall asleep faster and stay asleep longer.
