 Moderate Interaction

Be cautious with this combination:


© Medications Taken by Mouth (Oral Drugs) Interacts with Bistort

Bistort contains a large amount of chemicals called tannins. Tannins absorb substances in the stomach and intestines. Taking Bistort along with medications taken by mouth can decrease how much medicine your body absorbs, and decrease the effectiveness of your medicine. To prevent this interaction, take Bistort at least 1 hour after medications you take by mouth.



The appropriate dose of Bistort depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for Bistort. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using
