These days, scientists are busy in developing ‘Love potion.’ Animal studies have shown that the hormone oxytocin can 'reinforce' emotional feelings and enhance monogamy.

Research team led by Prof. Larry Young of Emory University in Georgia are studying the brain chemistry responsible for the complex feelings that actually draw people to a particular member of the opposite sex as well as help in keeping humans monogamous.

Prof. Larry Young said that there is intriguing overlap between the brain areas involved in vole pair bonding and those associated with human love.

He added: "For one thing, drugs that manipulate brain systems at whim to enhance or diminish our love for another may not be far away."

Researchers said that the treatments could be used to aid marriage counselling or even help a person stay monogamous.
