Recent studies have shown that many of the drugs, natural chemicals, and herbs that are claimed to be aphrodisiacs are actually ineffective. There are very limited food or medicine that can definitively boost a person's drive for sexual activity, but they are not fully effective in all subjects. 

According to a report from the Seeker, for the last thousand years that mankind has searched for a substance that can increase a person's desire for sexual activity, there has been no compelling evidence that any of it is truly effective.

There may be a chance that the wondrous effects of these super drugs can be attributed to how much a person "believes" it to be effective. The Placebo effect may be one of the considerations that need to be factored in, in which a person can physically show desirable effects of a "drug" in the event that a person is unaware that a "false" pill or treatment has been provided.

According to a report from HellaWella, substances and food such as chocolate, honey, and oysters may contain certain naturally produced chemicals such as serotonin, a chemical believed to play an important role in a person's emotions, particularly pleasure. The ingestion of these foods does not have any significant effect on people who suffer from erectile and sexual dysfunctions, even if they contain the "pleasure" chemical.

Other substances such as ginkgo biloba and ginseng may seem to be "promising," as Time reported. However, scientists are quick to point that no statistics can fully support their effectiveness. It is important to understand that the chemical process and system of love making simply cannot be stimulated by any drug.

On a positive note, there are performance-enhancing drugs that are effective to prevent premature ejaculation and improve erection quality. Some of these are used to reverse what is known as temporary erectile dysfunction. Nonetheless, they are not ingested to improve a person's "sexual drive," and performance-enhancing drugs cannot be considered as aphrodisiacs.
