Helichrysum gymnocephalum

Helichrysum gymnocephalum is a species of flowering plant in the family Asteraceae found in Madagascar. [1] It is used locally for its alleged aphrodisiac, antiseptic, and stimulant properties, and also as a treatment for bronchitis. [1] The essential oil is sold internationally for these same purposes. [2] This oil mostly consists of 1,8-Cineole, the organic compound Eucalyptol, which may account for these properties. [3]

In 1999, the non-profit organization Seacology helped to preserve this and other plants by creating a national park around Mt. Angavokely, near Antananarivo in Madagascar. [1]

Madagascar Island country in the Indian Ocean

Madagascar, officially the Republic of Madagascar, and previously known as the Malagasy Republic, is an island country in the Indian Ocean, approximately 400 kilometres off the coast of East Africa across the Mozambique Channel. At 592,800 square kilometres (228,900 sq mi) Madagascar is the world's second-largest island country, after Indonesia. The nation consists of the island of Madagascar and numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is endemic.

Peppermint Hybrid flowering plant in the family Lamiaceae

Peppermint is a hybrid mint, a cross between watermint and spearmint. Indigenous to Europe and the Middle East, the plant is now widely spread and cultivated in many regions of the world. It is occasionally found in the wild with its parent species.

Essential oil Hydrophobic liquid containing volatile aroma compounds from plants

An essential oil is a concentrated hydrophobic liquid containing volatile chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does not mean indispensable or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism.

Basil Important culinary herb

Basil, also called great basil, is a culinary herb of the family Lamiaceae (mints). It is a tender plant, and is used in cuisines worldwide. In Western cuisine, the generic term "basil" refers to the variety also known as sweet basil or Genovese basil. Basil is native to tropical regions from Central Africa to Southeast Asia. In temperate climates basil is treated as an annual plant, however, basil can be grown as a short-lived perennial or biennial in warmer horticultural zones with tropical or Mediterranean climates.

<i>Helichrysum</i> Genus of flowering plants

The genus Helichrysum consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is Helichrysum orientale. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Greek words ἑλίσσω and χρῡσός.

<i>Cananga odorata</i> Species of tree

Cananga odorata, known as ylang-ylang or cananga tree, is a tropical tree that is native to the Philippines, Malaysia, Indonesia, New Guinea, the Solomon Islands, and Queensland, Australia. It is also native to parts of Thailand and Vietnam. It is valued for the essential oils extracted from its flowers, which has a strong floral fragrance. Ylang-ylang is one of the most extensively used natural materials in the perfume industry, earning it the name "Queen of Perfumes".

Thymol Chemical compound found in plants including thyme

Thymol, C10H14O, is a natural monoterpenoid phenol derivative of p-Cymene, isomeric with carvacrol, found in oil of thyme, and extracted from Thymus vulgaris, ajwain, and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. Thymol also provides the distinctive, strong flavor of the culinary herb thyme, also produced from T. vulgaris.

Citronella oil

Citronella oil is an essential oil obtained from the leaves and stems of different species of Cymbopogon (lemongrass). The oil is used extensively as a source of perfumery chemicals such as citronellal, citronellol, and geraniol. These chemicals find extensive use in soap, candles and incense, perfumery, cosmetic, and flavouring industries throughout the world. Citronella oil is also a plant-based insect repellent and has been registered for this use in the United States since 1948. The United States Environmental Protection Agency considers oil of citronella as a biopesticide with a non-toxic mode of action.

<i>Chrysopogon zizanioides</i> Species of plant

Chrysopogon zizanioides, commonly known as vetiver and khus, is a perennial bunchgrass of the family Poaceae.

<i>Helichrysum petiolare</i> Species of flowering plant

Helichrysum petiolare, the licorice-plant or liquorice plant, is a species of flowering plant in the family Asteraceae, native to South Africa — where it is known as imphepho — and naturalized in parts of Portugal and the United States. Growing to about 45 cm (18 in) high and 150 cm (59 in) broad, it is a trailing evergreen subshrub with furry grey-green leaves and small white flowers. Other common names include silver-bush everlastingflower, trailing dusty miller and kooigoed. The foliage has a faint licorice aroma, but Helichrysum petiolare is not closely related to the true liquorice plant, Glycyrrhiza glabra.

Eucalyptol Chemical compound

Eucalyptol is a monoterpenoid. A colorless liquid, it is a bicyclic ether. Eucalyptol has a fresh mint-like smell and a spicy, cooling taste. It is insoluble in water, but miscible with organic solvents. Eucalyptol makes up 90% of eucalyptus oil. Eucalyptol forms crystalline adducts with hydrohalic acids, o-cresol, resorcinol, and phosphoric acid. Formation of these adducts is useful for purification.

Caryophyllene Chemical compound

Caryophyllene, more formally (−)-β-caryophyllene, (BCP), is a natural bicyclic sesquiterpene that is a constituent of many essential oils, especially clove oil, the oil from the stems and flowers of Syzygium aromaticum (cloves), the essential oil of Cannabis sativa, rosemary, and hops. It is usually found as a mixture with isocaryophyllene and α-humulene, a ring-opened isomer. Caryophyllene is notable for having a cyclobutane ring, as well as a trans-double bond in a 9-membered ring, both rarities in nature.

<i>Helichrysum italicum</i> Species of flowering plant

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.

Eucalyptus oil is the generic name for distilled oil from the leaf of Eucalyptus, a genus of the plant family Myrtaceae native to Australia and cultivated worldwide. Eucalyptus oil has a history of wide application, as a pharmaceutical, antiseptic, repellent, flavouring, fragrance and industrial uses.

Seacology Nonprofit organization in the United States

Seacology is a nonprofit 501(c)(3) charitable organization headquartered in Berkeley, California, that works to preserve island ecosystems and cultures around the world. Founded in 1991, it began with the work of ethnobotanist Paul Alan Cox, who researched tropical plants and their medicinal value in the village of Falealupo in Samoa during the mid-1980s. When the villagers were pressured into selling logging rights to their rainforest in 1988 to build a new school, Cox and his wife offered to help secure funds for the new school in return for an agreement with the villagers to protect their forest. With the help of his friends and family, Cox secured the funds within six months, later earning him and the village chief, Fuiono Senio, the Goldman Environmental Prize for their efforts. Word spread throughout the islands, and with increasing demand for similar projects, Cox, along with Bill Marré and Ken Murdock, decided to form Seacology and expand their work internationally. For the first few years, the organization operated on a volunteer basis.
