This herb is an easily available and fairly potent remedy against spirits, its presence or regular digestion protects against vile spirits in general and vampires in particular, and it can also aid healing and exorcism.
Hypericum is a yellow-flowered growth that reaches near a yard in height, and smells vaguely of turpentine.
Hypericum is used to cure anxiety and depression, as well as to treat inflammation and infection, and cure wounds and burns. It may be prepared as an draught or an oil, depending on the use. When burned, the smoke of the plant drives away evil spirits.
Hypericum is also used as a taste additive in brandy (like wormewood), rendering it bitter and intensely red in colour. Such brandy is called Pericum brandy, and is used in the same medicinial compounds as hypericum.
Mandrake is the most potent herb. Used wisely it can bring riches, love and fertility, those less materially minded can glean insight from its juices. It grows only under gallows, and when picked its scream brings death.
