# Senna or Psyllium Husk?

Senna (Senna alexandrina) stimulates bowel movements, while psyllium husk (Plantago ovata) holds water and adds bulk to stools. This difference shapes how long they can be used and their warnings. The table is built from the sourced cards of both herbs.

## Good to know

-   If a laxative is needed every day, the cause of constipation should be checked by a doctor.
-   Senna can cause potassium loss; people on heart medicines, diuretics or corticosteroids should ask a doctor first.
-   Psyllium taken with too little fluid can block the gullet or bowel; take it half an hour to an hour apart from other medicines.
