Rhodiola and Opium Tincture

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

Minor

CNS DEPRESSANTS

Why this applies to Opium Tincture

Opium Tincture falls under CNS DEPRESSANTS — the group Rhodiola interacts with.

Theoretically, rhodiola might increase the risk of adverse effects when taken with CNS depressants.
A review of adverse event reports in Poland identified cases of excessive sedation, myoclonus, hypotension, and hallucinations when rhodiola was taken with haloperidol, diazepam, or alprazolam.
Severity Minor 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: paregoric (opium tincture) is an opioid, so it naturally slows things down. It calms the gut to stop diarrhea, but it can also make you drowsy and relaxed. Rhodiola is thought to nudge some of the same calming chemicals in the brain, so stacking the two could, in theory, add up to more sedation than you'd expect.

To be honest, the evidence here is thin. It's mostly a handful of anecdotal reports, and those involved stronger sedatives, not paregoric specifically. So I wouldn't panic. Just keep an eye out for extra sleepiness, lightheadedness, or feeling foggy, and avoid driving until you know how the combo affects you. Run it by your pharmacist or doctor first before adding rhodiola.

From our pharmacist’s overview on the Opium Tincture page

“Opium tincture (Paregoric) is an opioid, prescribed mainly for severe diarrhea, and like any opioid it slows the brain and breathing. That is why 78 of the 100 supplement ingredients on this page interact by adding sedation, and why the seven rated major, alcohol and kava among them, deserve your attention before the rest.”
