Decoction — Root

Where to find it

Obtaining the plant

Sea holly is found wild on dunes and beaches along the Atlantic and Mediterranean coasts, where its harvesting is sometimes regulated due to its ecological fragility; it is preferable to obtain it dried from an herbalist rather than harvesting it yourself.

Harvest season

When to harvest it

The root is traditionally harvested in autumn or early spring, when the plant concentrates its reserves, while the aerial parts are gathered in summer.
