He was also invited to be an auditor and associate of the La Revista Internacional de Farmacografia.

He was named professor of Pharmacy of the Universidad Literaria de Filipinas, which was founded by the Philippine Revolutionary Government on October 19, 1898. He was a member of the Malolos Congress and the Malolos Constitution. This gave birth to the First Philippine Republic.[6] While serving as professor at the literary university which was then based in Bulacan and Tarlac provinces, he also contributed to La Independencia, the official organ of the revolutionary movement, edited by revolutionary general Antonio Luna. When President Emilio Aguinaldo formed his cabinet in 1899, he named Guerrero secretary of agriculture, industry and commerce.

He was among those who founded the Liceo de Manila and became its president until May 1903. He became chairman of the board of the Pharmaceutical Union and member of the American Pharmaceutical Society.[4] In 1907, he was elected delegate to the First Philippine Assembly and named president of the committee on public instruction which entitled him to a seat in the board of regents of the University of the Philippines, which would be established the following year.

He also served as assistant director of the Bureau of Census and an official of the Bureau of Science. ResearchDuring the American occupation, he compiled data on Philippine medicinal plants.[7] In 1903, he published his paper, Medicinal Plants of the Philippine Islands which made pharmacology a basic medical science in the Philippines.[8] He also authored a study on "Medicinal Plants" in 1918. It contains 174 types of plants with medicinal properties.[6] His work was prepared for publication by Dr. W. H. Brown for the Bureau of Forestry.[9] Some of his important works are Notas Preliminares Sobre Las Materiales Colorantes Vegetales de Filipinas, Drogas Vegetales de Filipinas, and Medicinal Uses of Philippine Plants. HonorsIn recognition of his work in botany, taxonomists named a genus of plants, Guerreroia monocephala, and a species of orchids, Dendrobium guerreroi, in his honor. In 1921, the University of the Philippines conferred on Guerrero a degree of Doctor of Science honoris causa. Guerrero died on April 13, 1935, at the age of 82.
