Chamomile and Ginkgo Biloba: what the published research says

PubMed indexes 2 records that name Chamomile and Ginkgo Biloba together, either in the title or in an interaction, co-administration, or pharmacokinetic context.

It does not tell you whether to combine them.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

Track what you actually take.

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 Chamomile, Ginkgo Biloba, 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.
