The Daisy family (Asteraceae) is a large and varied family which can be loosely split into plants that looks like daisies, like dandelions or like thistles. Most are bitter with a range of culinary and medicinal uses. All the Asteraceae plants found here are daisy-like, with the exception is Salsify which looks like a large purple dandelion.
Tansy
Tansy (Tanacetum vulgare) is a tall perennial with aromatic toothed pinnate leaves and yellow-button flowers in clusters. Its strong scent is used as a flea repellent for pets – simply rub the leaves onto the fur – as well as a fly repellent if hung up in the house/placed under carpets. It will also deter ants and mice. A strong tea is used as a skin wash for scabies. Do not use internally, particularly in pregnancy, as the essential oil is too strong and overdoses can be fatal.
Feverfew
Feverfew (Tanacetum parthenium) has golden-green toothed leaves and daisy-like flowers. Despite its name, it is not traditionally used for treating fevers, being better for dispelling pain and inflammation in the head, joints or nervous system. Its bitterness helps improve mood and liver function. Taken daily over a six month period, chewing 3-5 leaves (no more) daily can reduce the incidence of migraines by 70%, while also improving sleep and reducing arthritic symptoms. Best eaten in bread, as it is very bitter.
