Poppy seed - side effects
I appreciate the contribution, but I remove the following wiki contribution as poppy seed is not a flavour enhancer.
"Poppy Seed Powder, made from inactivated poppy seed. It is used as a secret ingredient in some restaurants. Although it cannot add any flavour to food, it would make the food addictive. Occasional intake of poppy seed powder is not as harmful as smoking Opium, but long-term intake of this flavory agent would probably make people addicted to the food that has been added poppy seed powder. Note that Opium is illegal in some countries."
