Panax Notoginseng and Caffeine , Sodium Benzoate

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

Why Are There 2 Interactions?

Panax Notoginseng interacts with whole categories of medication. Caffeine , Sodium Benzoate falls into 2 of those categories, so it can interact with Panax Notoginseng 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 1A2 (CYP1A2) SUBSTRATES

1 of 2

Why this applies to Caffeine , Sodium Benzoate

Caffeine , Sodium Benzoate falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Panax Notoginseng interacts with.

Theoretically, taking Panax notoginseng might reduce the levels and clinical effects of CYP1A2 substrates.
Animal research shows that administering Panax notoginseng intravenously for 7 days before intraperitoneal injection of caffeine can decrease maximal blood levels of caffeine by 37%. This interaction was attributed to the ability of Panax notoginseng to increase the activity of CYP1A2.
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 caffeine with sodium benzoate, which is just caffeine paired with a solubilizer so it can be given as a medicine. Your liver clears caffeine mostly through an enzyme called CYP1A2. The thought here is that Panax notoginseng may speed up that enzyme, so your body could break caffeine down faster than usual. In practice that means the caffeine might not work as strongly or last as long, so you may notice less of the alertness or stimulant effect you're counting on.

Honestly, this comes from animal research only, where caffeine levels dropped by about a third. We don't have solid human data, so treat it as a theoretical heads-up rather than a real alarm. If you take this regularly, just mention it to your pharmacist or doctor.

Here's the gist for your caffeine and sodium benzoate product: your body clears caffeine mainly through a liver enzyme called CYP1A2. Panax notoginseng appears to speed that enzyme up, which would push caffeine out of your system faster and make it a bit weaker. So instead of more jitters, you'd more likely notice less of caffeine's usual pick-me-up, perhaps feeling tired or less alert sooner than expected.

That said, this comes from animal research only, where notoginseng dropped peak caffeine levels by about 37%. We don't have solid human data, so it's more of a theoretical heads-up than a proven problem. If you use both regularly, just mention it to your pharmacist or doctor so they can keep an eye on things.

From our pharmacist’s overview on the Caffeine , Sodium Benzoate page

“Caffeine and sodium benzoate is itself a stimulant medication, so the supplements most likely to cause trouble are the ones doing the same job. Seven of the 208 ingredients on file rate major, several of them stimulant herbs such as ephedra that can pile extra blood pressure and heart strain onto a drug already revving the nervous system.”
