About Cascara Sagrada

In pet food and supplements, cascara sagrada is dried bark from the buckthorn tree Rhamnus purshiana, added for its laxative action rather than nutrition.

Cascara sagrada is an herbal bark used as a stimulant laxative in some pet supplements rather than a nutrient or protein source, and it is sometimes included for short-term relief of constipation in dogs and occasionally cats. It can be effective for brief use but may cause abdominal cramping, diarrhea, dehydration and electrolyte imbalances, can interact with medications, and should not be used long-term or in pregnant, dehydrated animals or those with bowel obstruction or inflammatory bowel disease—always consult your veterinarian before use.

Why it's used

The bark's active compounds, anthraquinones known as cascarosides, draw fluid into the colon and stimulate peristalsis, which is why formulators reach for it when a product targets short-term constipation relief. It contributes no protein, fat, or micronutrient value to a diet.

Common concerns

  • GI and electrolyte effects Anthraquinone laxatives like cascara sagrada can cause intestinal cramping and diarrhea, and overuse is associated with fluid loss and electrolyte imbalance.
  • Regulatory status in humans The FDA reclassified cascara sagrada laxative products in 2002 into a category no longer recognized as effective for over-the-counter human use, reflecting broader concerns about the ingredient's risk-benefit profile.
  • Long-term or chronic use Extended use of anthraquinone laxatives has been associated with colon atony and dilatation rather than sustained laxative benefit.
  • Cats Some veterinary-facing poison resources list cascara sagrada as a substance that can produce vomiting and weakness in cats if ingested outside directed use.

Also relevant

Because its effect is pharmacological rather than nutritional, cascara sagrada is typically found in supplement or remedy-style products rather than everyday complete-and-balanced pet foods.
