Herbalism

Herbal medicine (or "herbalism") is the study and use of medicinal properties of plants. The scope of herbal medicine is sometimes extended to include fungal and bee products, as well as minerals, shells and certain animal parts.
Plants have the ability to synthesize a wide variety of chemical compounds that are used to perform important biological functions, and to defend against attack from predators such as insects, fungi and herbivorous mammals. Many of these phytochemicals have beneficial effects on long-term health when consumed by humans, and can be used to effectively treat human diseases.

Herbal (book of herbs)
A herbal is "a collection of descriptions of plants put together for medicinal purposes." Expressed more elaborately — it is a book containing the names and descriptions of plants, usually with information on their virtues (properties) — and in particular their medicinal, tonic, culinary, toxic, hallucinatory, aromatic, or magical powers, and the legends associated with them. A herbal may also classify the plants it describes, may give recipes for herbal extracts, tinctures, or potions, and sometimes include mineral and animal medicaments in addition to those obtained from plants.

Magical Uses Of Herbs
Anise
Fill a small pillowcase with anise seeds and sleep on it. This will ensure that you have no nightmares. Use in protection and meditation incenses. Fresh anise leaves placed in a room will drive off evil, and they are sometimes placed around the magic circle to protect the magician from evil spirits. It also averts the evil eye. Anise seed is also used in purification baths, especially with bay leaves. It is used to call forth spirits to aid in magical operations, and a sprig hung on the bedpost will restore lost youth.

Boneset
The plant wards off evil spirits. Make an infusion and sprinkle about the house to drive away evil.

Celery
Chew the seeds to aid in concentration, or use in spell pillows to induce sleep. Burned with orrisroot, celery seed increases psychic powers. The stalk, along with the seeds, induces lust when eaten. Witches supposedly ate celery seed before flying off on their brooms that they wouldn't become dizzy and fall.
