It is able to live in all types of soils, although it tolerates to a lesser degree those clays that retain a large amount of moisture. The lack of drainage impairs their root development.

  • Pyrogallic tannins
  • Alkaloid (leunucardin and stachydrin)

Antioxidant and anti-inflammatory effect

The content in triterpenoids (Ursanus type) of leonurus cardiac they are strong inhibitors of superoxides produced in cellular activity. Therefore, they have a great antioxidant activity and even anti-inflammatory power.

Different studies corroborate this antioxidant capacity, both by these triterpenoids and by the flavonoids present in different parts of the plant.
