Huang Lian Su Tablets

This formula is essential for travel to areas of the world with primitive sanitation or questionable water quality. It is remarkably effective in killing the pathogens that cause the dreaded traveler's diarrhea.

The extract is prepared from the rhizome of Coptis chinensis (huang lian), and the active ingredient is berberine, a powerful constituent with strong antibiotic effects. Also found in North American goldenseal and Oregon grape, berberine gives these pills their beautiful golden color.
