It is difficult to prove or disprove that aphrodisiacs help libido. The fact that someone uses something that claims to be an aphrodisiac has a powerful impact on the mind. The consequences may be due to psychological effects or the brain releasing certain chemicals to stimulate the respective organs. The effects are so diverse and vague that at this point of time, they can't be proven scientifically. Plant aphrodisiacs include vegetables, fruits, nuts and grains.
Some vegetables have shapes which are suggestive to the imagination.
They have thus been attributed to contribute towards libido. The asparagus and artichoke are representatives of such type of vegetables which are eaten in the belief that they posses special properties as hinted by their appearances. Little is known about the chemical components which act as aphrodisiacs. This is a male hormone that is able to stimulate the sexual arousal of females. All other vegetables like carrot, fennel and onion are reputed to be good for libido but there is lack of scientific proof to back up their claims.
