Its members are characterized by the presence of resin ducts in the bark and feature compound leaves and unisexual flowers. Notes from the Eclectic Physicians. Cashew nuts should be planted at the beginning of the rainy season. The Sicilian sumac (Rhus coriaria ) of southern Italy is especially useful, as its leaves can have a tannin concentration of 2035%. It is now widely grown in tropical climates for its cashew "nuts" and cashew apples. The cashew family, Anacardiaceae, consists of about 80 genera and more than 700 species distributed primarily in tropical and subtropical areas of the world. Hartmann, H. T., et al. [1][3], Cashews are commonly used in South Asian cuisine, whole for garnishing sweets or curries, or ground into a paste that forms a base of sauces for curries (e.g., korma), or some sweets (e.g., kaju barfi). The oil is found on the outer shell (similar to mangos, where its found on the skin) and roasting the cashews at high temperatures can kill any remaining oil that makes its way through to the nut. It also is the name for the commercially important kidney-shaped, nut-like seed of this plant, which is edible when roasted or cooked. The leaves are spirally arranged, leathery textured, elliptic to obovate, four to 22 centimeters long, and two to 15 centimeters broad, with a smooth margin. The lacquer tree (Rhus verniciflua ) occurs in China and Japan, where the viscous, milky sap of this plant has long been collected and applied as a natural varnish to fine wood carvings and furniture. 1919: Ellingwood. Can fireworks be seen from several miles away? Each flower is small, pale green at first, then turning reddish, with five slender, acute petals seven to 15 millimeters long. [10], John Lindley described the "essential character" of the Anacardiace, the "Cashew Tribe" in 1831, adopting the order that was described by de Jussieu, but abandoning the name Terebintace.

The leaves are typically compound, with at least three if not more leaflets per leaf. The recommended soil media for cashew nut seedlings is in the ratio of 2:1:150 where: 2 is two buckets of soil, 1 is one bucket of well-decomposed farmyard manure, and 150gms of DAP. Its fruit is known as a mango, possessing a yellow-red skin with a large, flat seed surrounded by a tasty, juicy pulp, which can be yellow, red, or orange in color. What color does blue and green and pink make when mixed together? [4], The genus Pistacia has sometimes been separated into its own family, the Pistaciaceae, based on the reduced flower structure, differences in pollen, and the feathery style of the flowers.

Some members[which?] In Goa, India, the cashew apple is the source of juicy pulp used to prepare fenny, a locally popular distilled liquor. Cashew is an evergreen tree with deep tap roots, grown for its edible fruits (nuts).

The fruits are either a one-seeded drupe or a many-seeded berry, and are generally eaten and dispersed by birds or small mammals. Some people develop an increased sensitivity to this toxic oil with increased exposure; others appear to not have been initially affected by contact with poison ivy and its relatives, but subsequent exposures then elicit sensitive responses. The topsoil and sub-soil are kept separately and allowed to wither under the sun. The term false fruit (pseudocarp, accessory fruit) is sometimes applied to a plant structure that resembles a fruit, but is not derived from a flower or flowers.

The caustic, phenolic resin contained within the shell casing of the cashew, which also is known as Cashew Nut Shell Liquid (CNSL), has a variety of industrial uses, which were first developed in the 1930s. The seed kernal, cashew apple, wood, and caustic resin urushiol are utilized. These include polyols, which have recently seen increased demand for their biobased origin and key chemical attributes such as high reactivity, range of functionalities, reduction in blowing agents, and naturally occurring fire retardant properties in the field of rigid polyurethanes, aided by their inherent phenolic structure and larger number of reactive units per unit mass. Propagation through grafting starts by raising rootstock propagated from local cashew nut varieties. Externally it produces blisters, which are apt to be troublesome and difficult of cure. Andrea Thompson, Jeffery DelViscio and Elah Feder. Many species have foliage, fruits, or bark on the stems and roots that contain an acrid, often .
