I find the best way to understand the possible risks associated with a chemical is to search for the MSDS (Materials Safety Data Sheet) for that substance or product. Search on Google chemical name MSDS and you will get a ton of info. You really should familiarize yourself with any chemical and its potential hazards before using. The Merck Index is also a decent source, if you have access to a copy. Cupric sulfate is a mild corrosive and is orally toxic if you take too much, to answer the question.
