The words corruption and poison are not something anyone wants to associate with, let alone experience. So, when we combine them to form "poison of corruption", it creates a concept that is not only harmful but also difficult to eradicate. However, there are different synonyms that could be used to convey the same idea. Words like rot, decay, contamination, taint, and pollution could be appropriate depending on the context. These words convey the idea that something or someone is contaminated and is spreading a harmful effect, just like a poison. It is vital to identify the root cause of corruption and address it before it results in further harm.
