Senegalia catechu, previously known as Acacia catechu, is a deciduous, thorny tree which grows up to 15 m (50 ft) in height. [4] The plant is called kachu in Malay; the Malay name was Latinized to "catechu" in Linnaean taxonomy, as the species from which the extracts cutch and catechu are derived. [5] Other common names for it include kher, [6] catechu, cachou, cutchtree, black cutch, and black catechu.
Senegalia catechu is native to South Asia and Southeast Asia, including the Indian subcontinent, Myanmar, Cambodia and China (Yunnan). [1]
Through derivatives of the flavanols in its extracts, the species has lent its name to the important catechins, catechols and catecholamines of chemistry and biology.
The tree's seeds are a good source of protein. [7] Kattha (catechu), an extract of its heartwood, gives a characteristic flavor and red color to paan, a traditional Indian and Southeast Asian method for chewing betel leaf (Piper betle) with areca nut and slaked lime paste.
Branches of the tree are quite often cut for goat fodder and are sometimes fed to cattle. [3] [7] [8]
The heartwood, bark, and wood extract (called catechu ) are used in traditional medicine. [4] [9] The concentrated aqueous extract, known as khayer gum or cutch, is astringent. [10]
The tree is often planted for use as firewood and charcoal and its wood is highly valued for furniture and tools. [4] The wood has a density of about 0.88 g/cm3. [11]
Its heartwood extract is used in dyeing and leather tanning, as a preservative for fishing nets, and as a viscosity regulator for oil drilling. [4] Its flowers are a good source of nectar and pollen for bees.
The tree can be propagated by planting its seeds, which are soaked in hot water first. After about six months in a nursery, the seedlings can be planted in the field. [4]
Acacia s.l., known commonly as mimosa, acacia, thorntree or wattle, is a polyphyletic genus of shrubs and trees belonging to the subfamily Mimosoideae of the family Fabaceae. It was described by the Swedish botanist Carl Linnaeus in 1773 based on the African species Acacia nilotica. Many non-Australian species tend to be thorny, whereas the majority of Australian acacias are not. All species are pod-bearing, with sap and leaves often bearing large amounts of tannins and condensed tannins that historically found use as pharmaceuticals and preservatives.
Senegalia greggii, formerly known as Acacia greggii, is a species of tree in the genus Senegalia native to the southwestern United States and northern Mexico, from the extreme south of Utah south through southern Nevada, southeast California, Arizona, New Mexico and western Texas to Baja California, Sinaloa and Nuevo León in Mexico. The population in Utah at 37°10' N is the northernmost naturally occurring Senegalia species anywhere in the world.
Catechu is an extract of acacia trees used variously as a food additive, astringent, tannin, and dye. It is extracted from several species of Acacia, but especially Senegalia catechu, by boiling the wood in water and evaporating the resulting brew. It is also known as cutch, black cutch, cachou, cashoo, terra Japonica, or Japan earth, and also katha in Hindi, kaat in Marathi, khaira in Odia, khoyer in Assamese and Bengali, and kachu in Malay.
Cassia fistula, also known as golden shower, purging cassia, Indian laburnum, kani konna, or pudding-pipe tree, is a flowering plant in the family Fabaceae. The species is native to the Indian subcontinent and adjacent regions of Southeast Asia. It is the official state flower of Kerala state and Delhi UT in India. It is also a popular ornamental plant and is also used in herbal medicine.
Senegalia senegal is a small thorny deciduous tree from the genus Senegalia, which is known by several common names, including gum acacia, gum arabic tree, Sudan gum and Sudan gum arabic. In parts of India, it is known as Kher or Khor. It is native to semi-desert regions of Sub-Saharan Africa, as well as Oman, Pakistan, and west coastal India. It grows to a height of 5–12 metres (16-40'), with a trunk up to 30 cm (1') in diameter. Sudan is the source of the world's highest quality gum arabic, known locally as hashab gum in contrast to the related, but inferior, gum arabic from Red acacia or talah gum.
Acacia, commonly known as wattles or acacias, is a genus of about 1,084 species of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia, but is now reserved for species mainly from Australia, with others from New Guinea, Southeast Asia, and the Indian Ocean. The genus name is Neo-Latin, borrowed from the Greek ἀκακία, a term used in antiquity to describe a preparation extracted from Vachellia nilotica, the original type species.
Acacia melanoxylon, commonly known as the Australian blackwood, is an Acacia species native to south-eastern Australia. The species is also known as blackwood, hickory, mudgerabah, Tasmanian blackwood, or blackwood acacia. The tree belongs to the Plurinerves section of Acacia and is one of the most wide-ranging tree species in eastern Australia and is quite variable mostly in the size and shape of the phyllodes.
Vachellia tortilis, widely known as Acacia tortilis but now attributed to the genus Vachellia, is the umbrella thorn acacia, also known as umbrella thorn and Israeli babool, a medium to large canopied tree native to most of Africa, primarily to the savanna and Sahel of Africa, but also occurring in the Middle East.
Senegalia rugata is a spiny climbing shrub native to China and tropical Asia, common in the warm plains of central and south India. It is renowned as a raw material for shampoo, and the leaves and young shoots are often eaten. Archaeobotanical evidence shows its use for hair care in the pre-Harrapan levels of Banawali, some 4500–4300 years ago.
Vachellia nilotica, more commonly known as Acacia nilotica, and by the vernacular names of gum arabic tree, babul, thorn mimosa, Egyptian acacia or thorny acacia, is a flowering tree in the family Fabaceae. It is native to Africa, the Middle East and the Indian subcontinent. It is also considered a 'weed of national significance' and an invasive species of concern in Australia, as well as a noxious weed by the federal government of the United States.
Vachellia nilotica subsp. adstringens is a perennial tree. It is not listed as being threatened. Some common names for it are cassie, piquants blancs and piquant lulu. Its geographic distribution includes Africa, Asia, the Indian Ocean area and the Middle East.
Senegalia chundra is a perennial, deciduous tree found in Asia, India and in the Indian Ocean area. It grows 12 to 15 metres in height.
