#4 Mint induced saliva

As per the rules and regulations laid down by the ICC in regard to ball tampering, a cricketer is allowed to use saliva and sweat to make the ball shine. However, if you mix your natural saliva with another added substance, it becomes an offence.
One such case was of former England batsman Marcus Trescothick. He himself revealed in his autobiography that he used mint-induced saliva to make the ball shine, which in turn aided swing and helped England record their first Ashes victory in 18 years.
"It had been common knowledge in county cricket for some time that certain sweets produced saliva which, when applied to the ball for cleaning purposes, enabled it to keep its shine for longer and therefore its swing,” Trescothick wrote in his autobiography.
