Boswellia Serrata and Zuclopenthizol

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

Why Are There 2 Interactions?

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

Moderate

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

1 of 2

Why this applies to Zuclopenthizol

Zuclopenthizol falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Boswellia Serrata interacts with.

Theoretically, Boswellia serrata might increase the levels of CYP2D6 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2D6 enzymes.
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 explains PharmD, Clinical Pharmacist

Here's the gist for zuclopenthixol (Clopixol), which is an antipsychotic your liver clears partly through an enzyme called CYP2D6. In lab dish studies, boswellic acids from Boswellia serrata appear to slow that same enzyme down. If that happened in real life, your body might clear zuclopenthixol a bit slower, letting levels creep up. That could mean more of the usual side effects, like drowsiness, dizziness, dry mouth, low blood pressure when standing, or muscle stiffness and restlessness.

The important part: this is only a theoretical concern based on test-tube data, not real patients, so I don't want to alarm you. Still, since this is an active medication, it's worth a quick chat with your pharmacist or doctor before you combine them. Please don't change your dose on your own.

Moderate

IMMUNOSUPPRESSANTS

2 of 2

Zuclopenthizol also falls under IMMUNOSUPPRESSANTS.

Theoretically, Boswellia serrata might alter the effects of immunosuppressive drugs.
Some in vitro research suggests that Boswellia serrata extracts might inhibit mediators of autoimmune disorders such as leukotrienes and reduce production of antibodies and cell-mediated immunity. However, other in vitro research suggests that, when coupled with calcium ions, boswellic acids containing the keto group have immunostimulant properties within specific cell signaling pathways.
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

I want to be upfront with you: the interaction we have on file pairs Boswellia with immunosuppressant medications, but Zuclopenthixol (Clopixol) isn't actually one of those. It's an antipsychotic used to treat conditions like schizophrenia, and it works on dopamine signaling in the brain, not on the immune system. So the immune-related concern in the database doesn't really map onto how this medicine works.

On top of that, the evidence here is purely from lab and animal studies, and even those results pointed in conflicting directions. That makes any real-world effect with Zuclopenthixol very uncertain. I wouldn't expect a meaningful problem, but since I can't confirm a clear mechanism for this exact pair, please run it by your pharmacist or doctor before combining them.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

From our pharmacist’s overview on the Zuclopenthizol page

“Zuclopenthizol (Clopixol) is a sedating antipsychotic, and most of the 205 supplement interactions on record push in that same direction. Seventy-eight ingredients, including everyday alcohol and kava, deepen drowsiness, and the worst of them can dangerously slow breathing.”
