Feverfew is a medicinal herb commonly found in North American and Europe. Its unusual name is derived from the Latin word febrifugia, or "fever reducer," and while feverfew is often used for treating headaches, asthma, arthritis, and nausea, whether or not it actually reduces a fever seems to be debatable. This daisy-like perennial does, however, provide calming relief to red, irritated skin.
Extracts from its citrus-scented leaves can be used to treat everything from acne to insect bites to psoriasis. Also known for its skin-protecting antioxidant properties, feverfew also makes a decent insect repellant. Some products that include this natural ingredient include: Aveeno's Active Naturals Ultra-Calming Foaming Cleanser ($7), Neutrogena's Anti-Oxidant Age Reverse Day Lotion ($20), and First Aid Beauty Face Cleanser ($18).
