Plant characteristics and classification of St John’s wort
Occurrence and origin of St. John’s wort
St. John’s wort can be found on many parts of the earth. They can be found in both extreme and hostile regions, such as deserts or arctic tundra, as well as in the tropics or subtropics. Above all, it grows on fallow land, nutrient-poor meadows, forest edges, forest clearings and paths.
Plant order of St. John’s Wort
The St. John’s wort belongs to the family of St. John’s wort family (Hypericaceae), which includes about 600 to 700 species.
In botany, the true St. John’s wort is subdivided into various subspecies, which differ slightly in each case in the development of the leaves and flowers. Known subspecies are:
Broad-leafed St. John’s Wort (Hypericum perforatum ssp. Latifolium)
Small-leaved St. John’s wort (Hypericum perforatum spp. Microphyllum)
Common St. John’s wort (Hypericum perforatum ssp. Perforatum)
Narrow-leaved St. John’s Wort (Hypericum perforatum ssp. Angustifolium)
Characteristics of St. John’s wort
St. John’s Wort is a perennial herbaceous plant that can reach heights of growth of 50 cm to one meter (20 to 40 in). Sometimes, the plant forms very deep and branched roots that can reach up to 60 cm (24 in) into the ground.
The leaves look elongated and slightly oval and are arranged opposite. The leaves contain numerous oil glands and are 2 to 4 cm (0.8 to 1.6 in) tall. The striking dark spots on the leaves are oil tanks, which storage the essential oils of St. John’s wort. Both the leaves and the stems are hairless.
Between June and September the heyday of St. John’s wort is expected. The small flowers are golden yellow and joined together to form so-called cymes. The St. John’s wort flowers contain like the leaves a variety of oil glands, which, however, look rather reddish here. Because of this property, the St. John’s wort was for a long time one of the most important dye plants. Legend has it that the sap does represent the blood of John the Baptist. Striking are the stamens, which protrude far above the calyx as rays. The flowers usually appear at the time of the summer solstice. St. John’s wort is pollinated by insects.
The fruit of St. John’s wort is an egg-shaped capsule fruit, which is about 10 mm (0.4 in) long and has three compartments.
St. John’s wort – cultivation and care
Due to the curative effect but also due to the unmistakable flower splendor, St. John’s wort is cultivated occasionally in the garden or on the balcony.
The plant thrives best in sunny locations in the garden, for example, at the top of the herb spiral.
Soil can be lean to fertile. However, it is important that the ground is well drained and well ventilated. If it is grown in loamy locations, it is recommended to loosen the soil with a few drops of sand, perlite or vermiculite. St. John’s Wort tolerates neutral to slightly acidic soils. If the soil is acidic (pH below 5.5) it is recommended to lime the places where the herb should grow.
Sowing and cultivation
The common St. John’s wort is a light germ. The sowing can be done as pre-cultivating in shells or directly outdoors, whereby the sowing in the field is usually preferred. Its seeds can be sown between March and April and are only pressed slightly in the soil. If the herb is pre-cultivated in trays, the plant can be prick out as soon as the first leaves become visible. It is recommended to sow the St. John’s wort seed already in late October or early March. When growing St. John’s wort, make sure to keep a planting distance between each plant of about 30 cm (12 in).
St. John’s wort is a typical low feeder, which makes only very small demands on the nutrient supply. If the herb grows in commercially available herbal soil or in a well-managed garden soil, usually no additional fertilizer inputs are required.
St. John’s wort does not need special attention in terms of water supply. Shorter dry phases with high temperatures are generally well tolerated. For longer periods of heat (more than a week), the area should be poured vigorously.
When the St. John’s wort is in full bloom, it can be harvested. Cut the flower crowns and, if necessary, the leaves and stems.
The flowers can be dried in a shady and airy place. If oil is to be made with the plant parts, it is important not to collect the flowers and leaves in humid weather, but only when they have had the opportunity to dry in the sun. Otherwise, they threaten to mold in the oil.
Preparation of St. John’s wort oil
For the preparation of St. John’s wort oil, put dried flowers in a screw-top jar, fill with olive oil and leave the mixture covered in a dark place for three weeks. Externally, the anti-inflammatory oil can then be used for minor burns and rheumatic complaints.

Since then St. John’s wort is not only a mood-brightener, but also the most important herbal antidepressant.
At high doses, it can relieve mild and moderate depression after 4 to 6 weeks of use.
However, the conventional medical dosage is so high that it can not be achieved with teas or commercially available agents. For the officially necessary dosage for the relief of depression daily 900 mg to 1800 mg ( 0.03 to 0.06 oz) of St. John’s wort extract are necessary. As a drug for the treatment of moderate depression, some preparations are only available by prescription.
Conventional medicine makes the active ingredients hypericin and hyperforin responsible for the antidepressant effect.
The classical herbal medicine and the modern anthroposophic medicine consider the St. John’s wort as a plant that can store the sunlight of summer, to give the joy of sunny summer then in the dull winter and to brighten and warm the minds.
From this point of view, you can drink a St. John’s wort tea instead of commercially available supplements. Or you put the St. John’s wort in corn schnapps and make a tincture out of it. From this tincture you can take 20-50 drops three times a day.

When buying plants care should be taken that the soil is not too humid. Inasmuch as St. John’s wort is also to be considered for use as a medicinal herb, it is recommended to pay close attention to the botanical name.

The price for a plant is between 3 and 5 EUR/$. A package of seeds can be purchased for about 1.50 to 2.50 EUR/$.
