Infused oil of St. John’s Wort, commonly known as red oil (or l’ugghiu ciuriddu, sciuriddu) is a healing oily solution, a popular traditional ointment. It can be bought in herbal shops or pharmacies, but making it at home is very easy, following grandmother Benedetta’s recipe.
The perennial plant of St. John’s Wort (Hypericum perforatum) or St. John’s Herb can reach up to a meter in height. It is easily found on roadsides, in uncultivated meadows, and at the edge of cultivated fields.
Traditionally, the collection of these small, intensely yellow flowers is done during the Summer Solstice (between June 20 and June 22) at noon, or on St. John’s Day (June 24) but in reality, these little flowers can be picked anytime when they are fully opened. It is best to collect them away from roads or other pollution sources. The best time for harvesting this wild herb is during the waxing or full moon, in the morning when the dew has evaporated and the sun has not yet burned, so before noon. This is to take advantage of their full energetic and healing power.
BLOOMING SEASON of #StJohnsWort: from April to September.
Tradition recommends harvesting around the summer solstice..

St. John’s Wort Infused Oil
First, collect the flowers.
Do not wash them, at most, leave them in the open air on a tray to allow the insects to fly away. Use the flowers within a few hours of picking.
Place the fresh tops in a suitably sized jar without pressing too much, add the oil until they are all covered.
Leave the lid unscrewed for 7 – 10 days to allow the moisture from the flowers to evaporate, or cover with a net secured with an elastic band.
After the time has elapsed, you can close the jar hermetically.
Leave to macerate for 30 – 40 days, shaking occasionally, ideally daily. Expose the glass container to the sun to speed up the extraction process of its active ingredients (the Hyperforin must evaporate, while the Hypericin makes the oil red).
It is said that the oil in preparation should not be exposed to the moon, so it should be left in the sun during the day and taken indoors at night.
The St. John’s Wort oil is ready when it has a beautiful deep red color, usually, one month is enough.
Filter with a strainer (or funnel) and a cotton gauze. Press the flowers well with a spoon or inside a potato masher to recover all the infused oil.
Pour it into a dark glass bottle to protect it from the sun and store it in the medicine cabinet in the dark.
Better to use fresh or dried flowers?

FRESH FLOWERS: it is better not to seal the oil with fresh tops immediately, but to leave it for at least a week with the lid just resting or with a cotton gauze over it secured with an elastic band, to avoid most risks and side effects.
DRIED FLOWERS: they no longer contain aqueous parts and allow immediate and hermetic sealing of the jar exposed to the sun.
