Multiple studies demonstrate that natural plant extracts, such as those from yam, red spinach, and purple sweet potato, can successfully serve as acceptable and safer substitutes for crystal violet in bacterial staining procedures.

The analysis

The claim states that certain chemical substitutions are acceptable in Gram staining procedures. The retrieved literature includes multiple recent experimental studies (papers 9, 10, and 11) evaluating and validating the use of alternative natural extracts (yam extract, red spinach leaf extract, and purple sweet potato juice) to replace toxic crystal violet in staining bacterial morphologies. These papers directly support the claim. No papers refute it.
