Thunder God Vine and Temsirolimus

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

Why Are There 2 Interactions?

Thunder God Vine interacts with whole categories of medication. Temsirolimus falls into 2 of those categories, so it can interact with Thunder God Vine 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 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Temsirolimus

Temsirolimus falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Thunder God Vine interacts with.

Theoretically, thunder god vine might increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that triptolide, a constituent of thunder god vine, inhibits CYP3A4 enzymes in human microsomes. This interaction has not been reported in humans.
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 Temsirolimus (Torisel). Your body relies on a liver enzyme called CYP3A4 to help clear this cancer drug from your system. Lab studies suggest a compound in Thunder God Vine called triptolide may slow that enzyme down. If it does, temsirolimus could build up a bit higher than expected, which might mean stronger side effects like mouth sores, rash, fatigue, low blood counts, or raised blood sugar and cholesterol.

I want to be honest about the evidence though. This is theoretical, based on test-tube work, and hasn't actually been reported in people. Still, since temsirolimus is a serious chemo drug and Thunder God Vine can be toxic on its own, please don't combine them without first checking with your oncologist or pharmacist.

IMMUNOSUPPRESSANTS

2 of 2

Temsirolimus also falls under IMMUNOSUPPRESSANTS.

Theoretically, thunder god vine might enhance the effects of immunosuppressant drugs.
Large doses of thunder god vine may suppress immune function.
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 thing about pairing Thunder God Vine with Temsirolimus (Torisel). Temsirolimus already calms down the immune system as part of how it fights kidney cancer, and Thunder God Vine appears to do something similar, especially in larger or concentrated doses. So the concern is additive: stacking two immune-quieting agents could push your immune system down further than intended, which may raise the risk of infections or worsen the low blood counts and fatigue that already come with this medication.

I'll be honest, this warning is theoretical, based on how the herb behaves rather than hard studies in people on Temsirolimus. Still, since this is serious cancer therapy and Thunder God Vine itself can be toxic if dosed wrong, please run it by your oncologist or pharmacist before combining them.

From our pharmacist’s overview on the Temsirolimus page

“Temsirolimus (Torisel), an infusion for advanced kidney cancer, deserves genuine wariness around supplements. Most interactions on record involve herbs that alter CYP3A4, the liver enzyme that clears the drug, so a capsule can quietly raise its levels and side effects or thin out its anticancer effect.”
