Fo-ti, also known as Polygonum multiflorum or “He Shou Wu” in Chinese, is a valuable medicinal herb that has been used for centuries in traditional Vietnamese medicine and other Eastern practices. With its remarkable nutritional value and diverse applications, Vietnamese Fo-ti is increasingly asserting its position in both domestic and international markets.

Northern mountainous provinces such as Cao Bang, Ha Giang, Lao Cai, Yen Bai, and Lai Chau are the primary regions for cultivating Fo-ti, yielding the highest quality. Additionally, Fo-ti can be found in some central and Central Highlands provinces, though the production volume and quality may vary.
