Normally, the Candelilla plant is pulled out by hand from the roots, although ve a sharpened stick may be used to facilitate digging out the plant. In any of these vessels, the hot foam wax is separated by decanting from a brown liquor which precipitates to the bottom of the vessel and is later recycled to a removal bucket.
Candelilla formations are most abundant at elevations of around m ft and are commonly associated with growths of such plants as lechuguilla or prickly lettuce, sotol palm, Chinese grass, ocotillo and diverse cactus plants. The batch of Candelilla immersed in acid-water is heated over a direct fire until the solution comes to a boil, at which time the wax is separated candelillw the plant and fuses with the liquid.

In this way, about tons are produced annually. It is also used for making varnish.

Unfortunately, the manufacturing of Candelilla wax is still carried out using old and inefficient techniques which remain virtually unchanged since this activity first began. Manufacturing The commercial exploitation of the Candelilla plant for producing wax dates back to the beginning of the 20th century, and has since become one of the main economic activities of the Mexican region of the Chihuahuan Desert.

The plants root is relatively small, although a plant of moderate size can develop more than stalks of a grayish-green color, with typical dimensions of cm in long and 0. This is evidenced by the low yields and high costs in producing the wax.
It is mostly used mixed with other waxes to harden them without raising their melting point.
During the rainy cra the Candelilla plant becomes covered with small pink-colored flowers. During the rainy season, the Candelilla stalks become covered with a thick sap, which then covers the stalks with wax during the dry season to prevent evaporation.

The plants are then brought to collection centers where the process for extracting the wax is carried out. With a melting point of Using this technique, wax from the Candelilla plant floats to the surface in the form of foam.
Inthe botanist J. Candellla is yellowish-brown, hard, brittle, aromatic, and opaque to translucent.
The plants, scalded by the boiling process, are used as fuel for the cauldrons, once they have been put out to by sun-dried. Today, the Candelilla plant is considered useful xandelilla the treatment of a variety of illnesses.
