Long-term senna tea intake may lead to laxative dependence, electrolyte disturbances, and liver damage.

Furthermore, senna may negatively interact with certain types of medications, such as:

  • blood thinners
  • diuretics
  • steroids
  • licorice root
  • heart rhythm medications

If you have heart disease, inflammatory bowel disease (IBD), or liver disease, you should consult your healthcare provider prior to taking any senna product, as it may exacerbate these conditions.

Senna is not generally recommended for women who are pregnant or breastfeeding.
