Reduces Effectiveness

  • Teas and Herbs with Tannin

    Tannins are a group of unrelated chemicals that give plants an astringent taste. Herbs containing high amounts of tannins, such as green tea (Camellia sinensis), black tea, uva ursi (Arctostaphylos uva-ursi), black walnut (Juglans nigra), red raspberry (Rubus idaeus), oak (Quercus spp.), and witch hazel (Hamamelis virginiana), may interfere with the absorption of atropine taken by mouth.1

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Potential Negative Interaction

  • Iron
    Absorption of ferrous citrate, an iron compound that is usually well absorbed, is reduced in individuals taking hyoscyamine;3 therefore, these two substances should not be taken at the same time.
  • Anisodus tanguticus

    The herb Anisodus tanguticus contains a chemical that has effects similar to atropine, a compound related to hyoscyamine.7 Though no human studies have investigated a possible adverse interaction between hyoscyamine and anisodus, individuals should avoid the combination until more is known.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Explanation Required 

  • none

The Drug-Nutrient Interactions table may not include every possible interaction. Taking medicines with meals, on an empty stomach, or with alcohol may influence their effects. For details, refer to the manufacturers’ package information as these are not covered in this table. If you take medications, always discuss the potential risks and benefits of adding a new supplement with your doctor or pharmacist.
