Key Ingredients

Bismuth

鉍

Active Ingredient

Bismuth is one of the earliest known metals. In medical use, its radioactivity is below human background levels and behaves like stable elements, posing no biological impact.

Owing to its favorable safety and environmental profile, many bismuth compounds are used in medicines, cosmetics, and personal-care products.

Historically used in the treatment of syphilis, bismuth compounds have been widely used for nearly a century in oral gastrointestinal preparations with a favorable safety profile.

Bismuth is also a focus in advanced technologies (e.g., bismuth-based catalysis, solar cells, wearables, theranostics, and lead-free piping).

Ingredient overview

1

33.3

mg

Bismuth Subnitrate

It interacts with necrotic proteins at the site of gastrointestinal ulcers, forming a protective barrier over the ulcer wounds. This barrier prevents gastric acid, digested food, and other irritants from adhering to the intestinal wall, thereby alleviating abdominal pain and diarrhea.

2

44.4

mg

Bismuth Subgallate

It has an astringent effect, binding with secreted proteins in the gastrointestinal mucosa to form insoluble precipitates that protect the mucosa and reduce inflammation. Additionally, by reacting with hydrogen sulfide produced during abnormal fermentation in the intestine, it alleviates gas irritation of the digestive wall, decreases intestinal peristalsis, mitigates pain reflexes, and promotes the repair of intestinal cells.

3

44.4

mg

Albumin Tannate

Once in the intestine, albumin tannate is converted into tannate alkali by pancreatic juice, producing an astringent effect that helps stop diarrhea. In addition, tannic acid coagulates proteins to form a protective film that inhibits intestinal secretions, further contributing to its anti-diarrheal properties.
