Senna Leaf
Senna leaf is a stimulant laxative herb used for short-term relief of occasional constipation. It works by stimulating bowel movement rather than gently softening stool, which is why it’s effective—but also why it shouldn’t be used daily or long-term.
Key Benefits
- Effective short-term support for occasional constipation
- Typically works within 6–12 hours (often taken at night)
- Useful for temporary situations (travel, short-term sluggishness)
Common Issues It May Help With
- Occasional constipation
- Temporary sluggish bowels
How To Use (Simple)
- Tea: use the smallest effective amount
- steep briefly (5–10 minutes) and take at night. Capsules: follow label directions. Use short-term only (generally a few days) unless a clinician directs otherwise. Pair with water intake and dietary fiber when appropriate.
Taste / Notes
Bitter, earthy; often blended with mint or fennel to improve flavor.
Evidence Level
Good evidence as a short-term stimulant laxative; not a general wellness herb and not intended for ongoing daily use.
Cautions
HIGH CAUTION: Do not use long-term or daily—can cause dependency, worsening constipation, electrolyte imbalance (especially low potassium), abdominal cramping, and dehydration. Avoid during pregnancy/breastfeeding unless clinician-approved. Avoid if you have inflammatory bowel disease, intestinal obstruction, unexplained abdominal pain, or severe dehydration. Stop if you have severe cramps, diarrhea, or signs of dehydration.
Interactions
Diuretics and corticosteroids can increase risk of low potassium when combined with senna Digoxin risk increases with low potassium—avoid combining unless clinician-supervised May reduce absorption of oral medications—separate by at least 2 hours Use caution with warfarin if diarrhea occurs (can affect INR indirectly)
