Tarragon and Indiplon

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

Moderate

CNS DEPRESSANTS

Why this applies to Indiplon

Indiplon falls under CNS DEPRESSANTS — the group Tarragon interacts with.

Evidence from animal research suggests that tarragon essential oil can cause sedation and motor impairment when administered intraperitoneally at a dose of 1 mL/kg. Theoretically, concomitant use of tarragon with CNS depressants, including antihistamines, barbiturates, benzodiazepines, and tricyclic antidepressants, may increase sedative and other adverse 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

Indiplon is a sleep medicine in the same family as drugs like zolpidem, so it already works by calming your central nervous system to help you fall asleep. The concern here is simply additive: tarragon's essential oil has shown sedative effects in animal studies, so layering it on top of Indiplon could theoretically deepen that drowsy, sluggish feeling. That might mean more next-morning grogginess, dizziness, trouble with coordination, or feeling unusually out of it.

Keep this in perspective, though. This is a theoretical caution based only on animal research using concentrated tarragon oil, not real human cases. A little tarragon in your cooking is very unlikely to matter. Concentrated extracts or the essential oil are where I'd be more careful. Before combining them, just check with your pharmacist or doctor.

About Tarragon

What is Tarragon?

Tarragon
  • Digestive upset
  • Appetite stimulation
  • Sleep and mild restlessness
  • Toothache and oral discomfort
  • Blood sugar support (preliminary)
  • Culinary flavoring

Tarragon is a flavorful culinary herb that has been used in traditional medicine for digestion, sleep, and other complaints, but solid human evidence for any health benefit is lacking. Amounts used in cooking are generally considered safe, while concentrated extracts and the essential oil should be used cautiously because tarragon contains estragole, a compound studied for possible safety concerns. Talk to your pharmacist or doctor before using tarragon as a supplement.
