St. John's Wort
No plant embodies the SUN like St. John's Wort (Sint-Janskruid / Hypericum perforate). From how it looks, to where it grows (open fieds, exposed to the sun), to how it acts on us, everything about it is solar.
The name "perforatum" refers to the leaves that have tiny wholes, but also refers to "perforated" skin - puncture wounds with nerve damage - and a "perforated" aura/energy field. Those who's aura is no longer intact experience fatigue and a lack of vitality and optimism. Life force is seeping out, causing melancholy. St. John's Wort will seal these wounds and provide an influx of light, life force and vitality, thereby gently lifting the spirit. It strengthens and resets the enteric brain (nervous system in the gut), which is also the seat of instincts. In this way, the person is less sensitive to outside influences that might cause damage to the aura.
St. John's Wort is a powerful liver cleanser and can undo the effects of some forms of medication.
St. John's Wort also creates photosensitivity (the skin becomes sensitive to the sun - be careful), but when macerated in oil, it can be used as after-sun lotion.
