Helichrysum italicum is a species of flowering plant in the family Asteraceae. It is sometimes called the curry plant because of the strong smell of its leaves. Other common names include Italian strawflower and immortelle. It grows on dry, rocky or sandy ground around the Mediterranean. The stems are woody at the base and can reach 60 centimetres (24 in) or more in height. The clusters of yellow flowers are produced in summer, they retain their colour after picking and are used in dried flower arrangements.
Helichrysum Italicum Oil (aromatherapy)
Helichrysum Oil is a pale yellow, oily liquid of powerful and diffusive, but pleasant and rich, natural odor. The topnote has certain features in common with those of the extracted material (everlasting absolute), and these topnotes are not exactly attractive at high concentration. The sweetness is so rich and overwhelming, honeylike and deep, that it takes more than the average of imagination to appreciate the odor of this oil. However, the sweet-fruity and tealike, delicate undertone is unique, and the tenacity is quite outstanding.
