Cascara sagrada (Rhamnus purshiana), traditionally known as “sacred bark,” has long been used in herbal medicine as a stimulant laxative and later adopted into homeopathic practice. This review provides a comprehensive overview of its botanical characteristics, phytochemical profile, homeopathic sphere of action, therapeutic indications, and safety considerations. In homeopathy, Cascara sagrada is valued particularly for its regulatory influence on the digestive tract, liver, and portal circulation. The remedy is characteristically indicated in chronic, habitual constipation with hard, dry stools, persistent straining, and a sensation of incomplete evacuation. Associated symptoms include abdominal fullness, sluggish digestion, hepatic congestion, dull headaches, mental and physical heaviness, and urinary hesitancy. Its action reflects a broader theme of “bowel inertia leading to systemic torpor.” Clinical applications extend to constipation with portal congestion, haemorrhoids, headaches linked to digestive stagnation, and rheumatic discomforts arising from impaired elimination. Differential remedies such as Nux vomica, Bryonia alba, and Rhamnus californica help refine remedy selection. Though homeopathic potencies are generally safe, the herbal form of Cascara carries significant risks such as electrolyte imbalance, dependency, and hepatotoxicity, prompting regulatory restrictions. Proper prescribing requires matching the totality of symptoms, choosing appropriate potency, and supporting lifestyle modifications to restore natural bowel rhythm and digestive balance. Cascara sagrada remains a useful homeopathic remedy when applied judiciously with awareness of its broader systemic indications.
