A systematic review of the pharmacokinetic and pharmacodynamic interactions of herbal medicine with warfarin.

PloS one · 2017 · PMID 28797065

Systematic ReviewHuman subjects

“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.”

Names Garlic Extract and Ginger Extract together in an interaction, co-administration, or pharmacokinetic context.

Clinical evidence of herb-drug interactions: a systematic review by the natural standard research collaboration.

Current drug metabolism · 2008 · PMID 19075623

Case ReportsReviewHuman subjects

“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.”

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Garlic Extract, Ginger Extract, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
