St. John’s wort oil: St. John’s Wort is a plant known since ancient times: let’s discover the properties of the precious hypericum oil, also known as St. John’s Wort oil, red.


Which of you has never heard of St. John’s wort, the Anglo-Saxon name of Hypericum (Hypericum Perforatum)?

Hypericum is a herbaceous plant that grows wild in the fields and along the country roads of Europe and North America. Its flowers, with five yellow petals and numerous long stamens, appear from June to August and can be collected for herbalist use in autumn. A curiosity about hypericum: the Anglo-Saxon name of the plant (St. John’s wort) is attributed to the fact that the plant flowers at the feast of St. John (June 24th). In herbal medicine the leaves and flowering tops are used.

St. John’s wort oil: what it is and how it is prepared

As already discussed in a last post, oleolites (or “macerated oils“) are extracts obtainable by maceration (30-90 days) in an oily vehicle and they are filtered by squeezing the vegetable well. The oleolite of St. John’s wortand a few others is effective only if obtained from a fresh plant.

St. John’s wort oil is prepared by soaking fresh Hypericum flowers in virgin olive oil (25-30 grams of flowers in 100 ml of olive oil) for 6 weeks in tightly closed bottles, at room temperature, then expose to sun until the preparation takes on a ruby ​​red color (caused by hypericin but also by other naphthodiantronic derivatives). Filter and store in dark glass bottles (1,2). Although virgin olive oil is usually recommended and used, sunflower oil also seems to ensure good extraction of the active ingredients, adding less greasiness and better flowability of the finished product.
