    Drug interactions: Potassium depletion from long term use/misuse may intensify the action of cardiac glycosides. May antagonize antidiarrheal drugs. Interferes with the absorption of iron and other minerals when taken internally.

    Side Effects: (Possible adverse effects and/or overdose effects) With long term use or abuse: electrolyte losses, especially of potassium; pigmentation in the intestinal mucosa (melanosis coli). Abdominal cramps, diarrhea.

    Warning: Not for long-term use. Do not use in excess of 8-10 days. In sufficient quantities, potassium or sodium oxalate (soluble forms) can cause the precipitation of calcium into calcium oxalate (insoluble form) in the blood causing hypocalcemia and acute kidney failure due to calcium oxalate crystals in the renal tubules. Tannins are incompatible with alkalies, gelatin, heavy metals, iron, lime water, metallic salts, strong oxidizing agents and zinc sulfate. Tannins precipitate proteins. Tannins may cause bowel irritation, kidney irritation, liver damage, irritation of the stomach and gastrointestinal pain. Long-term and/or excessive use of herbs containing high concentrations of tannins is not recommended. A correlation has been made between esophogeal or nasal cancer in humans and regular consumption of certain herbs with high tannin concentrations (Lewis, W.H. and M.P.F. Elvin-Lewis. 1977.
