Diuretics

Diuretics help the body get rid of excess fluid and increase the amount of urine your body makes. Elderberry may also act as a diuretic, so taking it along with a diuretic could make that drug stronger and raise your risk of dehydration. European elder (also called black elder), is the one used most often for medicinal purposes. Avoid dwarf elder (Sambucus ebulus), which can be toxic. Use a trusted preparation of elder because raw or unripe fruit as well as the leaves, seeds, and bark contain a chemical related to cyanide, which is poisonous.
