In Mexico, it is distributed in warm, semi-warm, and temperate climates from sea level to , present in disturbed vegetation associated with dunes, mangrove edges, savannah, tropical forests deciduous, subdeciduous, subperennial, and perennial, xerophytic shrubland on plains or hills, spiny forest, on the edges of cloud forest, oak and pine forests.
Properties.
The yellow rose is commonly used against jaundice, also known as tiricia, yellow mal or infectious jaundice. As a remedy for this ailment, it is advised to soak the bark of this tree along with that of guázima ("Guazuma ulmifolia") and with this water bathe the sick person, it can also be taken as drinking water. On some occasions, it is recommended to pour water into a small canoe made with the wood of this tree and let it rest overnight to then drink it. In Quintana Roo and Oaxaca, an infusion is prepared with the leaves and/or bark. For the same purpose, it is used in Sonora and in the State of Mexico, where jaundice is recognized as "yellow spots by biliary infection."
However, the flower is also used, in the form of a potion to reduce fever and relieve the flu. Boiled it is used for baths against scabies and for washing burns, in which case the crushed leaves are also applied to them. In decoction, it is used as a rinse after bathing for urticaria or malaria, although in this case it can be drunk.
In Veracruz, its use is only mentioned in the bite of a snake or snake bite by spreading the powder over the affected area. Other medicinal uses given to this plant are against diarrhea, liver diseases, and generally to stop postpartum and nasal hemorrhages, against pimples, and ulcers. Additionally, they are used as a pectoral and for curative baths.
The only reference found corresponds to Maximino Martínez in the 20th century, where its use for jaundice and as a pectoral is mentioned.
Little is known about the chemistry of "C. vitifolium". In the whole plant, the flavonoids naringenin and quercetin have been found. In the leaf, coumarin, ellagic acid, and the phenolic component gentisic acid, and in the root, the carotenoid vitexin.
