It has been studied for its effectiveness in both internal infections and topical wounds. Garlic’s broad-spectrum antimicrobial properties make it a staple in traditional medicine worldwide.
3. Oregano (Origanum vulgare)
Oregano oil is rich in carvacrol and thymol, compounds known for their antifungal effects against species such as Aspergillus and Candida, as well as antibacterial action against E. coli and S. aureus.

Its analgesic qualities also make it a common ingredient in dental care products to reduce pain and infection.
7. Goldenseal (Hydrastis canadensis)
Goldenseal contains berberine, an alkaloid with documented antibacterial and antifungal properties against pathogens like Candida albicans and MRSA strains.

It is traditionally used in South America for infections and inflammatory conditions, often taken as a tea or extract to support immune defense.
How to Choose
When selecting an antifungal herb with antibacterial properties, consider the specific infection type and location (skin, oral, systemic). The herb’s form (essential oil, tincture, capsule, or tea) affects potency and application method. Safety and potential allergies are important, especially with potent oils like tea tree or oregano, which require dilution. Also, look for standardized extracts to ensure consistent active compounds, and consult with healthcare professionals if combining herbs with conventional treatments.
