Chondrus, commonly referring to Chondrus crispus (Irish moss), has a history of traditional use primarily as a demulcent and mild laxative in herbal medicine, particularly in Irish and Caribbean folk remedies. Traditionally, it is used to soothe the mucous membranes of the digestive tract and to provide gentle bulk to stools, which can in theory help ease the passage of stool and thus reduce irritation for those with hemorrhoids. The gel-like polysaccharides (carrageenan) in Chondrus are thought to have mucilaginous properties, providing a protective coating that may soothe internal tissues, including those affected by hemorrhoids.

However, there is no strong scientific evidence supporting the efficacy of Chondrus for treating or supporting hemorrhoid symptoms specifically. While its bulk-forming and soothing actions are recognized in traditional systems, clinical trials or systematic reviews confirming its benefits for hemorrhoids are lacking. Most available references cite its general use as a demulcent or as a mild laxative rather than for targeted hemorrhoidal relief.

In conclusion, the use of Chondrus for hemorrhoids is primarily based on traditional practices with limited evidence, and it cannot be considered scientifically validated for this indication.
