How does it work?
Eastern hemlock contains tannins. Astringent chemicals, such as tannins, can cause the mouth, throat, and digestive tract linings to shrink and form a protective surface coating.
Insufficient Evidence to Rate Effectiveness for...
- Digestive disorders.
- Diseases of the mouth and throat.
- Severe lack of vitamin C (scurvy).
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
LithiumInteraction 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.
The appropriate dose of eastern hemlock 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 eastern hemlock. 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.
