Cascara sagrada is a natural laxative made from the bark of the buckthorn tree. It works by increasing the contractions of the large intestine to promote bowel movements.

What does Cascara sagrada help with?

• Constipation: Cascara is one of the most well-studied herbal laxatives. Its active compounds stimulate the colon to contract and move stool along, while also pulling water into the bowel to keep things soft. Most people see results within 6 to 12 hours.
• Chronic constipation: For people who struggle with ongoing constipation, cascara can provide reliable relief. It's best used short-term or cyclically rather than every day, since the colon can become dependent on stimulant laxatives over time.
• Bowel irregularity: When the digestive system is sluggish due to travel, dietary changes, or stress, cascara can help reset the rhythm. It works gently enough that it's been used across age groups in traditional settings.
• Sluggish digestion: Traditional herbalists used cascara not just for constipation but for a general sense of digestive heaviness or fullness. Its mild bitter properties were also thought to stimulate bile flow and support digestion more broadly.
• Hemorrhoid discomfort (by softening stool): Straining during bowel movements is a major driver of hemorrhoid pain and worsening. By softening stool and reducing the effort needed to go, cascara can take pressure off irritated hemorrhoidal tissue.
• Bowel prep before procedures: Cascara has historically been used as part of bowel preparation protocols. Its reliable stimulant effect makes it useful before colonoscopy or other procedures requiring a clean colon, though modern medical prep solutions are now more common.
• Occasional bloating from backed-up stool: When bloating is caused by slow transit and stool buildup rather than gas alone, moving things along with cascara can bring quick relief. It addresses the root cause — stool not moving — rather than just treating the sensation.
• Liver and gallbladder sluggishness (traditional use): Traditional herbalists in both Indigenous American and later Western herbal medicine used cascara as a tonic for the liver and gallbladder, believing it supported bile production and fat digestion. This use is not well-studied in modern clinical trials but has a long historical record.
