Concentrated extracts may not be suitable for individuals with ulcers or very sensitive digestion.
Traditional sources commonly advise caution during pregnancy with concentrated internal use.
Sweetened horehound syrups and candies may contain substantial added sugar depending on the product.
Individuals with known plant sensitivities should introduce the herb carefully.
Always consult a qualified professional before using herbs for health purposes.
