Gypsywort (Lycopus europaeus Lamiaceae)

Other Names: Gipsywort, Bugleweed, European Bugleweed, Water Horehound

Gypsywort thrives in moist environments, often found along stream banks and other watercourses. It produces tiny white flowers with purple dots in inflorescences, blooming from July to September.

Parts for Use

Aboveground Parts

1. The plant can be used fresh or dried.
2. It is used to prepare infusions, powders, tinctures, or extracts.

Ingredients

Gypsywort contains flavonoids, tannins, and phenolic acid derivatives, notably caffeic and rosmarinic acid. It also includes a bitter essential oil, fluorine, and manganese. Its therapeutic effects stem from the synergistic action of these compounds, with reduced efficacy if components like manganese or tannins are removed.

Use in Treatment

Gypsywort is primarily used to treat hyperthyroidism by influencing iodine metabolism and thyroxine secretion. It is also effective for hormonal disorders, menstrual problems, and breast pain linked to thyroid overactivity. The plant may inhibit hormones related to sexuality, milk production, and glucagon, which regulates blood sugar. Its tannins help suppress dry cough and bleeding by tightening tissues. A 2000 study by Chinese scientists found that gypsywort leaf extract inhibits enzymes involved in uric acid production, suggesting potential for gout treatment.

Cultivation

Gypsywort grows well in moist soil in sunny or slightly shady locations. Seeds can be sown in fall or spring.
