Cascara Sagrada or Sacred Bark (Rhamnus purshiana)



Cascara sagrada (Rhamnus purshiana) is a shrub native to western North America whose bark is processed for medicinal purposes. Cascara sagrada contains organic plant compounds called anthraquinones that have powerful laxative effects.



Since the 1890s, Cascara sagrada has been listed on the U.S. Pharmacopeia, which contains standards for medications and supplements.

Cascara sagrada is also known by the names California buckthorn, bearberry, yellow bark, and sacred bark. It's called chittem and chitticum in the Chinook language of the Pacific Northwest. 



  • Cáscara sagrada or cinchona
  • Wild collection, so it is considered organic.
  • Product of wild collection, so they are free of chemicals.
  • A dietary supplement.
  • Mexican plant of wild collection, collected in its best state of maturity and dehydrated in the shade to preserve all its qualities.
  • Ideal ingredient for several preparations.
  • 100% Pure

Cascara sagrada is primarily used to treat constipation. The anthraquinones contained in the bark slow down the absorption of water and electrolytes in the intestines.
Because of this, stool volume increases as it absorbs the excess water, which increases pressure within the intestine. This stimulates muscle contractions in the colon (peristalsis), speeding the clearance of the bowel.
Cascara sagrada is considered a stimulant laxative, causing intestinal muscle contractions. In this way, it's similar to other natural laxatives like aloe vera and senna. However, unlike these counterparts, the effect of cascara sagrada tends to be gentler, resulting in fewer loose or watery stools.
Cascara sagrada works differently than demulcent laxatives like psyllium. This laxative creates a gel-like substance that helps ease stool from the bowels.
Cascara sagrada is no longer an FDA-approved laxative, but it's still used by people who prefer "natural" laxatives.
Generally speaking, cascara sagrada will induce a bowel movement within eight to 12 hours of taking a dose.
Cascara sagrada is believed by some to prevent or treat gallstones, liver problems, hemorrhoids, fissures, and even cancer. However, there is little to no evidence to support these claims.
Possible Side Effects
Cascara sagrada is intended for short-term use only. If used to treat occasional constipation, it is generally safe and well-tolerated. In some cases, it may cause abdominal pain and cramping (most commonly when used to treat severe constipation).
The long-term use of cascara sagrada is another matter. The concerns stemmed primarily from the evidence that anthraquinones may be harmful if overconsumed. Cascara sagrada can also cause a condition known as melanosis coli, discoloration of the lining of the colon.
If taken for more than a week or two, cascara sagrada may cause severe dehydration and the rapid loss of electrolytes. Electrolytes are minerals your body needs like sodium, potassium, and chloride. This can trigger an array of potentially serious side effects, including:
  • Severe nausea
  • Loss of energy
  • Headaches
  • Muscle weakness, spasms, or cramps
  • Irregular heartbeat (arrhythmia)
  • Skipped heartbeats (palpitations)
  • Rapid heartbeat (tachycardia)
  • Numbness or tingling of the hands or feet (neuropathy)
  • Reduced urine output
  • Confusion
  • Depression
  • Return of constipation (rebound constipation)
Excessive doses of cascara sagrada can cause bloody diarrhea, vomiting, and the inability to urinate (acute urinary retention). Call your healthcare provider or seek urgent care if you experience any of these symptoms.
If used regularly, cascara sagrada can lead to laxative dependence. The intestines will begin to adapt to the anthraquinones and become less able to work on their own. The long-term use of anthraquinones has also been linked, albeit weakly, to the development of colorectal growths (adenomas).
Dosage and Preparation
When cascara sagrada bark is processed, it is typically removed, diced, and dried for up to one year. This reduces its potency and makes it easier for your body to digest.
Some manufacturers will heat the bark to speed up the process. The dried bark can then be powdered or boiled and distilled for herbal products.
There is no recommended dosage of cascara sagrada. The effects can differ depending on a person's age, weight, health, and co-existing medical conditions.
The herb also comes in a multitude of formulations, including capsules, powders, tinctures, and teas. This can make it difficult to know how much or little of a product you need to achieve the desired effect.
When using cascara sagrada, never exceed the dosage on the label, and don't use it for more than three days.
