Tarchonanthus camphoratus (known as camphor bush for its scent, or leleshwa in Kenya), is a shrub or small tree, widespread in Africa south of the Sahel.
The camphor bush can reach up to 6 meters in height. The twigs and younger stems are white-felted, as are the undersides of the leaves. The upper leaf surface is dark olive-green. Bruised leaves smell strongly of camphor. Tarchonanthus camphoratus is dioecious. Flowers are usually present from December to May (in South Africa), with cream coloured panicles on a discoid head. Male flowering heads have several flowers whilst the female has only a few. The fruit is a dense and woolly achene. [3]
Tarchonanthus camphoratus wood is fragrant, close-grained, attractive, durable and rich in aromatic oils. It is used as wood fuel and a source of charcoal. [4] [5] It is also used as a traditional building material, in horticulture, and in tribal papermaking. Leleshwa is also a source of aromatic oils [6] [7] used as fragrances. Its leaves are used by the Maasai to scent their homes and persons.
Tarchonanthus camphoratus is used as a traditional remedy for respiratory illnesses. [8] The species has wide range of local uses, including dental hygiene.
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."
Sandalwood is a class of woods from trees in the genus Santalum. The woods are heavy, yellow, and fine-grained, and, unlike many other aromatic woods, they retain their fragrance for decades. Sandalwood oil is extracted from the woods. Sandalwood is often cited as one of the most expensive woods in the world. Both the wood and the oil produce a distinctive fragrance that has been highly valued for centuries. Consequently, some species of these slow-growing trees have suffered over-harvesting in the past.
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.
