The ideal Valentine gift? 2-Phenylethylamine (2-PEA), the LOVE molecule.
Phenylethylamine and Its Role in Love.
If it could really make two hearts as one, the Arrow of Love may have been spiked with phenylethylamine (PEA), the same organic compound contained in chocolates that causes you to walk in Cloud 9 similar to the feeling when you are crazy in love.
The delightful intoxicating feeling that is accompanied by the accelerated pounding of the heart is not simply a sign of being mushy, after all. It is the response of your body to the increase of the concentration of this compound in parts of the brain responsible for sexual excitement. Thus, phenylethylamine, or PEA, in the body was nicknamed the "molecule of love" while its supplemental counterpart the "love drug."
