28 Powerful Medicinal Plants to Plant in Your Garden (1)

Medicinal Plants

28 Powerful Medicinal Plants to Plant in Your Garden (3)

Consisting of little button flowers that resemble daisies, feverfew is easy to germinate and grow from seed.

Hardiness: Feverfew is perennial in zones 5-9.

Use: There’s some evidence that supplementing with feverfew can reduce migraine attack frequency. As a migraine sufferer myself, I’m always skeptical of so-called natural remedies, but there’s evidence that parthenolide, which feverfew contains, is an effective preventative. Of course, results vary widely. As any migraine sufferer knows, what works for one person may not work for another, unfortunately.
