It is also known as Red Willow or Willow Creole. Salix humboldtiana is an arboreal species belonging to the Salicaceae family. In Colombia, it is found in a fairly diverse altitude range that goes from 100 meters above sea level to 2600 meters above sea level in the departments of Amazonas, Antioquia, Cauca, Cundinamarca, Magdalena, Putumayo, Santander and Valle. (UNAL, 2021).
S. humboldtiana is a large tree that can reach 25 m in height without any problem. It has simple, elongated leaves with serrated edges that hang pendularly from the branches, which is why it receives the name “weeping willow”. The flowers are arranged in yellowish white catkins and dark brown capsular fruits.
It is a very important species in the protection of bodies of water because it grows on the banks of rivers, lakes or streams, playing the role of a protective barrier and filter against impurities. It also helps soil recovery, which makes it an ideal species for ecological restoration because it fulfills all the purposes of restoration: recovering soil, protecting water bodies, and attracting birds.
An important chemical component known as Salicin is extracted from Salix humboldtiana , which is present in the bark and to a lesser extent in the leaves. This chemical component makes it a species of great value for naturopathic medicine for the treatment of fevers, rheumatic and menstrual pain and externally to wash wounds (MHT, 2021).
