Calendula has been given internally for jaundice and fever where there is associated irritability and nervousness and acute hearing.
Calendula is one of the safest of culinary herbs, but if you are allergic to the pollen of species of the daisy family, such as ragweed, you may experience an allergic reaction to calendula, although it's not very likely.
Calendula is perhaps best known for its effectiveness in healing skin problems such as wounds, burns, insect bites, eczema, skin ulcers, and rashes.
