Goldenseal

Antimicrobial for the GI Tract

Goldenseal (Hydrastis canadensis) root has potent antimicrobial properties. Because the active ingredient appears to be an alkaloid, most of these anti-microbial properties remain confined to the GI tract.

Goldenseal has been found to be an effective antimicrobial against:

• Chlamydia
• E. coli
• Salmonella typhi
• Entamoeba histolytica
• Staphylococcus aureus
• Streptococcus sanguis
• Pseudomonas aeruginosa
• Helicobacter pylori
• other Gram-positive bacteria and fungi

Some studies suggest that goldenseal may also be effective against viruses, fungi, protozoans and helminths (worms).

Look for goldenseal products with standardized berberine/hydrastine (alkaloid) content as these will have the highest potency.

Because goldenseal is becoming a threatened species, some conscientious formulas contain Goldthread (coptis chinensis) in addition to goldenseal to supplement the berberine content of the formula.

Goldenseal is a special order product - please call.
