The Helichrysum flower was well-known in ancient Greece for its beauty, as well as its medicinal properties. It is thought that these flowers were once dried and arranged as an offering to the Greek Gods.
The name we use for it now comes from Greek, helios or Sun, from the Titan of myth, Helios, that drove the shining golden chariot of the sun, and chrysos for gold, or golden, which refers to the bright sunny flowers that are a trademark of this plant. This sunny little plant, which is a relative of the daisy, got it’s other common names of Immortelle and Everlasting from the flower’s retention of their bright yellow color when dried, and this might be why the dried flowers were used as offerings by the Greeks. The Romans used it to treat word cuts, and was also used traditionally in the Mediterranean to treat colds and chest ailments. Used as a strewing herb in the Middle Ages, it was also used in folk healing for skin conditions and healing scars. In Africa it has a traditional use of treating rheumatism, since it is a wonderful anti-inflammatory, and was known as Geelsewejaartjie which translates roughly to “bright yellow flowers that last seven years in the house.” It is also said it is one of the herbs used by Moses to help protect the Israelites from the plagues in the Old Testament.
Later on in Italy its curry-like flavor made it a widely used culinary addition, it does have a curry like smell, but the taste is more bitter like sage or wormwood. Different parts of the plants such as the young shoots and leaves are stewed with meat or vegetables to impart their flavor. It also is a fairly powerful cat repellent, but since it is poisonous to felines (and will take over any where it is planted) it should be planted with caution, and mindfulness of where kitties tend to venture.
Here is a great article I found with some quick and recipes with this versiatile flower.
