What the Science Says
Wild Geranium Rhizome comes from Geranium maculatum, a North American wildflower. Its root is exceptionally rich in tannins — plant compounds with astringent properties — and was historically used by Native Americans and early settlers as a remedy for diarrhea, wounds, and mouth sores. There is no published clinical trial data to confirm these traditional uses work in humans at supplement doses.
What It Doesn't Do
No proven cardiovascular benefits — that claim comes from social media posts, not studies. Won't treat infections or serious digestive disease. No evidence it does anything beyond what tannins generally do. Don't confuse it with Pelargonium sidoides (Umcka), a different plant with its own separate research.
Absorption & Bioavailability
Unknown — no pharmacokinetic or absorption studies found in the provided data
Red Flags to Watch For
- Zero published clinical trials found on PubMed — all health claims are based on traditional use or unverified web sources
- High tannin content may interfere with iron absorption and reduce absorption of certain medications if taken together
- Often confused with Pelargonium sidoides (Umcka geranium), a completely different plant with different evidence
- Appears in over 1,000 registered supplement products despite having no clinical trial backing
- Social media sources are being used to spread cardiovascular benefit claims with no scientific support
