Which herb is described as antimicrobial, anti-inflammatory, and astringent, with mucous membrane infection indications?

• A. Hydrastis canadensis
• B. Ginkgo biloba
• C. Geranium maculatum
• D. Grindelia robusta

Answer: (A)

Hydrastis canadensis (goldenseal) best fits this combination because it provides broad antimicrobial activity, supported by the plant’s berberine content, along with anti-inflammatory effects and astringent action that tightens and dries mucous membranes. This trifecta makes it useful for mucous membrane infections such as those of the oral, nasal, or GI mucosa, where you want to reduce microbial burden, quell inflammation, and dry secretions. The other herbs do not consistently offer all three properties together—one is mainly a strong astringent without notable antimicrobial action, another lacks the mucous-membrane antimicrobial profile, and the last is valued for inflammation but not primarily for mucous-m membrane infections.
