Preparation of St. John’s wort oil

Around the 24th of June, the name day of Saint John the Baptist, the delicate golden flowers of Hypericum perforatum are blooming at La Comba, like elsewhere in Provence.

It is this active substance which provides the healing function of the plant, which is both soothing in case of sunburn, and also has antidepressant properties.

In order to prepare Saint John’s wort oil, we collect the flowering tops and macerate them in olive oil for at least three weeks. We take a glass bowl and fill it with olive oil, and then add a maximum of Saint John’s wort flowers.


We let the bowl stay outside in the sun and thereby make a solar maceration.

Slowly the active principles in the flowers will be absorbed in the olive oil which will start turning beautifully red in color. After three weeks, we can press, filter and bottle the oil, so it can preserve its healing properties for years.
