Lithium
Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.

Eastern hemlock might have an effect like a water pill or "diuretic." Taking eastern hemlock might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.



Medications taken by mouth (Oral drugs)
Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.

Eastern hemlock contains a large amount of chemicals called tannins. Tannins absorb substances in the stomach and intestines. Taking eastern hemlock 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 eastern hemlock at least one hour after medications you take by mouth.
