Oakmoss (scientific name Evernia prunastri) is a species of lichen. It can be found in many mountainous temperate forests throughout the Northern Hemisphere. Oakmoss grows primarily on the trunk and branches of oak trees, but is also commonly found on the bark of other deciduous trees and conifers such as fir and pine. The thalli of oakmoss are short (3–4 cm in length) and bushy, and grow together on bark to form large clumps. Oakmoss thallus is flat and strap-like. They are also highly branched, resembling the form of antlers. The colour of oakmoss ranges from green to a greenish-white when dry, and dark olive-green to yellow-green when wet. The texture of the thalli is rough when dry and rubbery when wet. It is used extensively in modern perfumery.

Commercial uses

Oakmoss is commercially harvested in countries of South-Central Europe and usually exported to the Grasse region of France where its fragrant compounds are extracted as oakmoss absolutes and extracts. These raw materials are often used as perfume fixatives and form the base notes of many fragrances. [1] They are also key components of Fougère and Chypre class perfumes. The lichen has a distinct and complex odor and can be described as woody, sharp and slightly sweet. Oakmoss growing on pines have a pronounced turpentine odor that is valued in certain perfume compositions.

In parts of Central Italy, oakmoss has been used as for biomonitoring the deposition of heavy metals at urban, rural, and industrial sites. Studies of bioaccumulation for zinc, lead, chromium, cadmium, and copper in lichen samples were performed five times at regular intervals between November 2000 and December 2001. As expected, the rural areas showed smaller impact of those five heavy metals when compared to urban and industrial areas. [2]

Health and safety information

Oakmoss should be avoided by people with known skin sensitization issues. [3] Its use in perfumes is now highly restricted by International Fragrance Association regulations, and many scents have been reformulated in recent years with other chemicals substituted for oakmoss. [4]

Conservation status

Evernia prunastri is listed as critically endangered (CR) in Iceland, where it is found in only one location. [5] As of April 2021, it has not been evaluated by the IUCN.

Perfume is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. Perfumes can be defined as substances that emit and diffuse a pleasant and fragrant odor. They consist of manmade mixtures of aromatic chemicals and essential oils. The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory."

<span class="mw-page-title-main">Lichen</span> Symbiosis of fungi with algae or cyanobacteria

A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship. Lichens are important actors in nutrient cycling and act as producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches (fruticose); flat leaf-like structures (foliose); grow crust-like, adhering tightly to a surface (substrate) like a thick coat of paint (crustose); have a powder-like appearance (leprose); or other growth forms.

<span class="mw-page-title-main">Musk</span> Class of aromatic substances used in perfumes

Musk is a class of aromatic substances commonly used as base notes in perfumery. They include glandular secretions from animals such as the musk deer, numerous plants emitting similar fragrances, and artificial substances with similar odors. Musk was a name originally given to a substance with a strong odor obtained from a gland of the musk deer. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world. The name originates from the Late Greek μόσχος 'moskhos', from Persian mushk and Sanskrit मुष्क muṣka derived from Proto-Indo-European noun múh₂s meaning "mouse". The deer gland was thought to resemble a scrotum. It is applied to various plants and animals of similar smell and has come to encompass a wide variety of aromatic substances with similar odors, despite their often differing chemical structures and molecular shapes.

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

Cananga odorata, known as ylang-ylang or cananga tree, is a tropical tree that is native to and originated in the Philippines and spread to Malaysia, Indonesia, New Guinea, the Solomon Islands, and Queensland, Australia. It is also native to parts of Cambodia, Thailand, India 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".

<span class="mw-page-title-main">History of perfume</span>

The word perfume is used today to describe scented mixtures and is derived from the Latin word, "per fumus," meaning through smoke. The word perfumery refers to the art of making perfumes. Perfume was refined by the Romans, the Persians and the Arabs. Although perfume and perfumery also existed in East Asia, much of its fragrances were incense based. The basic ingredients and methods of making perfumes are described by Pliny the Elder in his Naturalis Historia.

<i>Lobaria pulmonaria</i> Species of lichen

Lobaria pulmonaria is a large epiphytic lichen consisting of an ascomycete fungus and a green algal partner living together in a symbiotic relationship with a cyanobacterium—a symbiosis involving members of three kingdoms of organisms. Commonly known by various names like tree lungwort, lung lichen, lung moss, lungwort lichen, oak lungs or oak lungwort, it is sensitive to air pollution and is also harmed by habitat loss and changes in forestry practices. Its population has declined across Europe and L. pulmonaria is considered endangered in many lowland areas. The species has a history of use in herbal medicines, and recent research has corroborated some medicinal properties of lichen extracts.
