Nature's Sunshine Cascara Sagrada Review 2026: Worth the Price?
Checks out. — Mostly Legit

"Cascara sagrada is an effective natural laxative"
Cascara contains cascarosides, anthraquinone compounds that trigger colon muscle contractions. This mechanism is well established in pharmacology texts.
German Commission E monograph on Rhamnus purshiana -
"Product implies safe traditional remedy for a 'clean, healthy colon'"
FDA pulled cascara sagrada from its approved over-the-counter laxative list in 2002 for lack of safety data, though it's still sold as a supplement.
FDA Final Rule, 21 CFR Part 310 (2002) -
"No active compound dose listed on label"
The label states only 'cascara sagrada bark' with no hydroxyanthracene glycoside percentage, so buyers can't judge strength or compare potency.
Consumer advice
This is a real stimulant laxative, not a wellness gimmick - treat it like you would Senokot or ex-lax, not a daily supplement. Follow the label: short-term use only, don't take it if you have diarrhea or abdominal pain, and check with a doctor if you're pregnant, nursing, or on medication. If you need regular fiber support instead of a stimulant laxative, psyllium husk or a magnesium citrate supplement is gentler for long-term use. Chronic use of stimulant laxatives like this one can cause your colon to become dependent on them, so don't use it as a everyday habit.
