Edholm was appointed World's Superintendent of Press work, at the Boston Convention of the Woman's Christian Temperance Union (WCTU) in 1891.

For many years, her work averaged 250 columns of original material, in which every phase of the labors of the WCTU was depicted in thousands of papers in the English-speaking world.

Edholm became so interested in the plight of these betrayed and enslaved girls that she determined to make social purity work her specialty, and continued to speak and write on their behalf.

[5] In 1886, Edholm moved to Oakland, California and was unanimously elected official reporter for the WCTU; in 1891, she was named superintendent of press.

She served as secretary for the International Federation Women's Press League[6][4] and was editor of The Christian Home in Oakland.

[6] For years, Edholm was interested in the rescue of trafficked girls and she wrote hundreds of articles in defense of outraged womanhood, in such papers as the Woman's Journal, The Woman's Tribune, and the California Illustrated Magazine, where her articles depicted the horrors of the slave traffic in Chinese women for immoral purposes.

[5] In 1901, Edholm founded the Lucy Charlton Memorial, named after her mother, as a home for unfortunate women and children.
