Betony

In the middle ages, much value was placed on the betony plant due to its vast medicinal qualities, and was considered to be able to cure all diseases.

Said to have originated in Spain, it grows about 40 - 50 cm, has a woody stem, with rough, 5 - 10cm long leaves which produce a bitter oil.

Dried leaves can be smoked (to relieve headaches) or infused as a weak tea. The fresh leaves are said to have an intoxicating effect, and can also be used for dyeing fabrics yellow.

Also known as Bishopswort.
