Lower Bowel Stimulator (NEW Formula)

Lower Bowel Stimulator is an updated version of Nature's Sunshine's longtime favorite formerly known as LBS II. It's a blend of seven herbs — including cascara sagrada bark, buckthorn bark, licorice root, ginger, turkey rhubarb root, fennel seed, and cardamom — formulated to support healthy bowel regularity and comfortable elimination. The new formula comes in a vegetarian hypromellose capsule, reflecting a move toward clean-label ingredients.

Cascara sagrada bark works on the peristaltic muscles of the bowel and encourages the normal flow of bile and digestive secretions. Buckthorn bark is a well-known herb for loosening the bowels, while licorice root gently supports peristalsis and general digestion. Ginger root aids digestion and soothes the digestive tract, turkey rhubarb root provides traditional support for healthy bowel function, and fennel seed and cardamom have been added to promote digestive comfort and help ease occasional cramping.

Take 2–4 capsules daily with a meal. This product contains cascara sagrada, buckthorn, and turkey rhubarb, so it's not intended for prolonged use. Do not use if diarrhea, loose stools, or abdominal pain are present or develop, and please see your healthcare provider before use if you are pregnant, nursing, have any medical condition, or are taking medication.

It's designed for adults looking for support with healthy bowel regularity and occasional constipation. It may also appeal to those interested in gentle colon or whole-body cleansing. Anyone who is pregnant, nursing, taking medication, or managing a medical condition should consult their healthcare provider before use.

The original Lower Bowel Stimulator (LBS II) remains available while supplies last and uses the classic formula with couch grass, Oregon grape, and capsicum. This new version replaces those with fennel seed and cardamom for a gentler experience with less occasional cramping. For broader cleansing goals, Nature's Sunshine also offers CleanStart 14-Day Cleanse, Liquid Cleanse, Bowel Detox, and Tiao He Cleanse, each taking a different approach to digestive and whole-body cleansing support.
