The Homeopathic Physician who novelized Clarín

In classic fiction literature, homeopathy is not very often mentioned, so it was curious to find in the novel "His only son", by Leopoldo Alas, Clarín, a character defined as a "Homeopathic Doctor". Could it be possible that, as in his other novel "La regenta", the book was based on real people and, consequently, a homeopathic doctor practiced in Oviedo at the end of the 19th century? This work is the summary of the search for this doctor, his discovery and his curious biography.
