(Hypericum perforatum)

At present, we focus on a medicinal plant useful for double wounds, on the one hand, for any external damage to the skin, and on the other for the “wounds of the nerve,” for modulation of the nervous system with predominant effect of calming and mood improving.

History and features

His English name “St. John ‘ s wort ‘ (the plant of St. John) relates to the tradition of its collection at the saint. Jan, 24. but the true origin of the label is only supposed to be (whether based on a legend by which it grew out of the blood of St. John the Baptist, or was named after the Knights of St. John of Jerusalem, often using the Yiddish for the treatment of wounded crusades). The name of the genus “Hypericum” comes from the Greek words “hyper” (above, above) and “eikon”, following the tradition of his hanging over the religious images in the house for the discouragement of evil during the day of St. John. The generic name “Perforatum” refers to the presence of small transparent oil glands in leaves that can be seen when viewing against light. Its use extends to ancient Greece when Dioskorides (a botanist, physician, 40-90 BC) recommended it outside for the treatment of burns, internally for the treatment of sciatica, repeated fever (malaria). At present, the Slovene is one of the best-selling natural products in the US (as an antidepressant, for an interest with an annual turnover of $ 550 million).
There are around 400 species within the genus Hypericum enlarged globally, therefore it is necessary to distinguish the plant from other species by characteristic dots on the leaves (white) and on the edge of the florets (black) and the cross section of the stem (round to slightly flattened, i.e. not A square belonging to an abundantly extended type of H. vulgaris). A confirmatory feature of the species is also red silk flowing out after the flower has been squeezed, commonly referred to as “the blood of St. John “.

After closing the bottle, leave for 2 weeks in a sunny place, respectively. In heat, occasionally shake, and after oil maceration, the oil is preceded (we push well from the flowers) into dark bottles. This red colored oil should not be missed in any canine or human medicine cabinet.
