Feverfew

Feverfew has been used in medicinal applications for centuries. As the name suggests, it can be used to treat fevers, but there is some question as to the effectiveness of this practice. Instead, it's become popular for use in the treatment of migraines. A decoction sweetened with honey or sugar is sometimes used to relieve light coughing or wheezing.

It's a great herb to use externally as well - make a tincture or ointment to apply onto insect bites to relieve itching or swelling.

Feverfew is also used to treat issues with menstrual cramping and difficult childbirth, when brewed into a tea. If you are experiencing either of these things, consult a medical professional before using feverfew as treatment.
