Milagros Vrac̆  had showed interest in her father's, Thaddeus Vrac̆ (1215-1287), research from a young age and accompanied him in his studies and material gathering. At 14 she already joined him as an assistant in his studies of the Līmāx funginus. One of their earliest developments was a method to collect the Līmāx funginus highly poisonous spores, which were then carefully studied for potential use in various remedies. For example, they found that lightly roasted spores could be infused for an ointment that reduces inflammations.

Milagros is also known for developing efficient methods of storage, both for the components and the resulting concoctions, as well as the processing methods of ingredients. She developed a unique set of tools, utilizing various materials, which became a stamp of Vrac̆ potion making. Her keen observations of the effects materials had on each other were used in alchemical research centuries after her passing.

Note: at this point in history, surnames were not generally used, however, the moniker “Vrac̆”, meaning “healer”, was used for early members of this family line, and later members did adopt it as a surname. Therefore, while not entirly accurate historically, the 'surname, given name' convention has been kept for early members of this line for convenience.
