Botanical Information
Botanical Name: Alisma orientale
Family: Alismataceae
Ze Xie is derived from the rhizome of an aquatic perennial plant native to China and other parts of East Asia. The plant grows in marshy or watery environments and produces a tuber-like underground stem that is harvested for herbal use.
After harvesting, the rhizome is cleaned, sliced, and dried. Its pale color and starchy texture reflect the part of the plant traditionally used in Chinese herbal practice.
Because it comes from a water-loving plant, Ze Xie has long been associated in traditional herbal systems with the regulation and movement of fluids.
Historical Use of Ze Xie Herb
Ze Xie has been used in Chinese medicine for many centuries and is recorded in traditional materia medica texts as an herb that drains dampness and promotes urination.
Historically, it has been valued for its role in formulas intended to support proper water metabolism and clear damp-heat or deficient heat patterns that involve fluid imbalance. It is also well known for its inclusion in classical kidney and fluid-regulating formulas.
