Key findings

What the studies concluded.

Reviews and human studies first. Each quote is the authors’ own conclusion about their study, not a NutriStack assessment, and a single study is not a consensus.

“It was difficult to determine whether ten herbal medicines had significant effects on the PK-PD parameters of warfarin. Low quality of evidence, different compounds within and different compositions of the herbs, and methodological limitations of the crossover study, which is a clinical study in which subjects receive a sequence of different interventions, made it difficult to form conclusions.”

“As herbal products (and dietary supplements in general) continue to grow in popularity, patients and health care providers should be vigilant of potential herb-drug interactions.”

Ulbricht et al. · 2008 · Review or meta-analysis · details

“In conclusion, garlic and ginger extracts modify pro-inflammatory cytokines. Alternative herbal remedies like garlic and ginger may be effective and safe colon cancer treatments.”

“As of writing, this was the first case report that may support an interaction between an oral anticoagulant and ginger together with a brief review of the literature on ginger and hemostasis. As this interaction was observed only by chance, this case highlights the importance of self-control of anticoagulation with coumarins particularly for the detection of unknown interactions.”
