Cascara Sagrada

Rhamnus purshiana

Laxative

Cascara sagrada is a stimulant laxative herb used for short-term constipation relief. It is NOT a daily ‘detox’ herb—overuse can cause dependency and electrolyte problems.

Key Benefits

Short-term constipation relief (stimulant laxative).
Can help trigger bowel movement when other gentle options fail.

Common Issues It May Help With

Occasional constipation (short-term only).

How To Use (Simple)

Use only short-term (typically a few days).
Follow label dosing strictly; start low.
Prefer gentler first-line options: magnesium citrate (if appropriate), prunes, psyllium, hydration, movement.

Taste / Notes

Very bitter if in tea form.

Evidence Level

Traditional use supported for laxative effect; safety limits long-term use.

Cautions

Do NOT use long-term. Avoid in pregnancy/breastfeeding, children, abdominal pain of unknown cause, IBS flares, or suspected obstruction. Overuse can cause cramping, diarrhea, dehydration, and electrolyte imbalance.

Interactions

Can lower potassium—use caution with diuretics, digoxin, steroids, or any meds affected by electrolytes.
