Corydalis Yanhusuo and Omeprazole, Sodium Bicarbonate

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

Why Are There 2 Interactions?

Corydalis Yanhusuo interacts with whole categories of medication. Omeprazole, Sodium Bicarbonate falls into 2 of those categories, so it can interact with Corydalis Yanhusuo 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 2C9 (CYP2C9) SUBSTRATES

1 of 2

Why this applies to Omeprazole, Sodium Bicarbonate

Omeprazole, Sodium Bicarbonate falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Corydalis Yanhusuo interacts with.

Theoretically, Corydalis yanhusuo might increase serum levels of drugs metabolized by CYP2C9.
Corydalis yanhusuo contains berberine. Preliminary clinical research shows that berberine can inhibit CYP2C9. Theoretically, Corydalis yanhusuo might also inhibit CYP2C9.
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.

Here's the gist with Konvomep (omeprazole plus sodium bicarbonate). Corydalis yanhusuo may contain berberine, which lab and early human research suggests can slow down a liver enzyme called CYP2C9. Omeprazole is cleared partly through that pathway (and partly through CYP2C19), so in theory the herb could let omeprazole linger a bit longer in your body and nudge its levels up.

If that happened, you might notice more of omeprazole's usual mild effects, things like headache, nausea, gas, or loose stools. Honestly, this is a theoretical concern based on how these compounds behave, not something proven in real patients, so I wouldn't lose sleep over it. Still, it's worth a quick chat with your pharmacist or doctor before pairing them, especially with concentrated supplement doses.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Omeprazole, Sodium Bicarbonate also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, Corydalis yanhusuo might increase serum levels of drugs metabolized by CYP3A4.
Corydalis yanhusuo contains berberine. In vitro research and preliminary clinical research show that berberine moderately inhibits CYP3A4. Theoretically, Corydalis yanhusuo might also inhibit CYP3A4.
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 gist: Corydalis yanhusuo may gently slow down a liver enzyme called CYP3A4, and your omeprazole (the heartburn part of Konvomep) is partly broken down by that same enzyme. If the herb blocks it a little, slightly more omeprazole could linger in your body. In plain terms, that might mean a touch more of the usual omeprazole effects or side effects, like headache, nausea, gas, or loose stools. The sodium bicarbonate (the antacid buffer) isn't really affected here.

Honestly, this concern is theoretical, based on lab work and the berberine in the herb, not on solid human studies. For most people it's unlikely to cause real trouble. Still, since omeprazole is meant for long-term comfort, run this combo past your pharmacist or doctor before adding the supplement.
