Yerbabuena is an annex of the Jalca Grande district, in the province of Chachapoyas, Amazonas. According to the testimony of many elderly people, its name is due to the medicinal plant “mint” that was abundant in this part of the Utcubamba river valley. The writing of the name using the letter “Y” has become widespread among the área.

It is located on the banks of the Utcubamba River. Geopolitically, it is the largest and most important annex, due to its evident importance in commercial, agricultural and labor development. Ancestral traditions such as barter are still maintained up to this day.

Every Sunday the inhabitants of more than 16 districts of the different provinces of our Amazon region gather indistinctly. Many arrive by foot from villages located in the heights and others do so by road. Also, people from other regions such as San Martín, Cajamarca, and Lambayeque come to form part of this great agricultural and commercial fair.
