The word "dokuzu" is not a standard Japanese word. It appears to be a combination of "doku" (毒), meaning "poison" or "toxicant," and "kuzu" (葛 or 屑), which can mean "arrowroot" or "trash/scum," according to a Japanese dictionary. Therefore, "dokuzu" doesn't have a direct, common meaning in Japanese. It's possible it's a misspelling, a slang term, or a word used in a specific context.
