Purple nutsedge, also known as Cyperus rotundus, is a perennial herb of damp places, long known to herbalists for its fragrant tuberous root. Traditionally used in Asia and the Mediterranean basin, it holds a discreet but ancient place in the herbal records concerning digestive and women's ailments.
The dried root was traditionally brewed as a tea to ease digestive discomfort, bloating, and heaviness after meals.
In certain Asian traditions, the tuber was used to help with irregularities in the menstrual cycle and associated discomfort.
The roots were sometimes used as a decoction to help with mild feverish states, according to old folk uses.
Root powder, mixed with water or an oil, was applied as a poultice to certain skin irritations in folk tradition.
Not advised during pregnancy due to a traditional use linked to the menstrual cycle, which suggests a possible action on the uterus. To be avoided during breastfeeding as a precaution, for lack of sufficient data. Do not use without the advice of a healthcare professional if taking medication, particularly anticoagulants. Prolonged or high-dose use is not documented as safe; favor occasional, moderate use.
