Herbal lower bowel formulas draw on some of the oldest plant remedies for regularity. CHF #5LB 100 Capsules is Country Health’s herbal formula for occasional constipation, a separate product from the Fiber Plus line, built around classic botanicals. Here is what research says about each ingredient.
Full ingredient list (per 1 capsule): vitamin C (as calcium ascorbate) 8 mg; calcium (as calcium ascorbate) 0.8 mg; pantothenic acid (as d-calcium pantothenate) 4 mg; proprietary blend 475 mg of butternut (Juglans cinerea) bark, cascara sagrada (Rhamnus purshiana) bark, trace mineral blend, Chinese rhubarb (Rheum palmatum) root, psyllium seed, apple pectin, Irish moss (Chondrus), and kelp (Ascophyllum nodosum). Other ingredients: microcrystalline cellulose, magnesium stearate, silica, gelatin (capsule). The label suggests one capsule with each meal.
What does cascara sagrada do?
Cascara sagrada is the bark of the Rhamnus purshiana tree and one of the best-known herbal remedies for occasional constipation. A 2015 review of botanical medicines for constipation lists cascara, along with senna, frangula, aloe, and rhubarb, among the most commonly used herbal laxatives. Mayo Clinic explains that stimulant ingredients like cascara derivatives work by triggering rhythmic contractions of the intestinal muscles, which helps move stool through the colon.
What is butternut bark?
Butternut (Juglans cinerea) is a North American tree related to the walnut. Its bark has a traditional reputation as a mild laxative, and it is paired here with cascara and rhubarb in the same spirit. It has not been evaluated in modern clinical trials, so its inclusion reflects traditional herbal practice.
How does Chinese rhubarb root work?
Chinese rhubarb root has been used for constipation for centuries. The NIH LactMed database explains that the root contains anthraquinones such as emodin and rhein, natural compounds that stimulate the bowel, along with tannins, which are astringent. LactMed also notes that Chinese and garden rhubarb are generally recognized as safe as foods by FDA. In CHF #5LB, rhubarb works alongside cascara to encourage the bowel’s natural movement.
What do Irish moss and kelp add?
Kelp is a brown seaweed, and the NIH Office of Dietary Supplements (ODS) describes seaweed as one of the best food sources of iodine. Iodine is an essential part of the thyroid hormones that help regulate metabolism. Irish moss (sea moss) is a red seaweed that LactMed notes is used as both food and traditional medicine. It naturally contains carrageenan and other plant carbohydrates, along with minerals.
What about the psyllium, pectin, and vitamins?
Psyllium seed and apple pectin are two plant ingredients that research links with regularity; a 2022 meta-analysis found both significantly improved stool frequency in adults with chronic constipation. In CHF #5LB they are included in small amounts as supporting ingredients rather than as the main event. Each capsule also provides 8 mg of vitamin C and 4 mg of pantothenic acid, two water-soluble vitamins.
How do these ingredients work together?
CHF #5LB brings together three traditional stimulant botanicals (cascara sagrada, rhubarb, and butternut) with seaweeds and small amounts of psyllium and pectin. The herbs encourage the colon’s natural contractions, making the formula suited to occasional use when things slow down. Mayo Clinic recommends pairing any laxative with the basics: fiber-rich foods, about 8 to 10 glasses of fluids a day, and regular exercise.
Who might enjoy it: adults who prefer a traditional herbal approach for occasional constipation and want a formula taken with meals.
Who should check with a clinician first?
Stimulant herbs are meant for occasional use. Mayo Clinic notes that using stimulant laxatives for weeks or months can make the bowel less responsive and can upset electrolyte balance. FDA does not permit cascara in over-the-counter laxative drugs because the safety data it requested were never submitted, though it can be sold as a supplement ingredient. Please check with your clinician first if you:
- Are pregnant (Mayo Clinic says stimulant laxatives may be harmful in pregnancy) or breastfeeding (LactMed advises avoiding cascara, rhubarb, and sea moss).
- Have abdominal pain, a possible bowel blockage, inflammatory bowel disease, or thyroid disease (seaweeds naturally contain iodine and can pick up heavy metals from the water they grow in).
- Take heart medicines, diuretics, or other prescription drugs.
Call your healthcare team right away if you have severe cramps, rectal bleeding, severe diarrhea, dizziness, or constipation lasting more than seven days.
