Mints and mint oils are common flavorings in candy, medicines, cookies, ice cream, and other oral products. In moderation, mint is harmless. But in large doses, it can reduce testosterone and libido and should be considered an anaphrodisiac or anti-aphrodisac. Menthol ('mint-oil') is a chemical that cools. It is an ingredient in some desensitizing lotions to slow a man's path to climax. And it can ~really~ cool a person if they consume too much over time.

A 2004 study in the journal Urology starts with doctors who received complaints from their patients that mint reduced sex drive. The doctors followed up by dosing rats with large amounts of peppermint or spearmint, which lowered their testosterone levels. The mint also caused an abnormality in the structures of the testicles - which were described as "segmental maturation arrest in the seminiferous tubules." (PMID:15302514)

So are the mints 'female herbs' that women should take in large doses to enhance their femininity? There's no herbalist tradition along those lines, and one study showed that large doses of mint can lead to abnormal changes in the uterus. (PMID:17120533)

Will using an Altoid ("curiously strong") mint to enhance oral sex make you impotent, or make your partner sexually listless? No. The men that suffered from peppermint poisoning were taking much larger doses. Enteric peppermint oil is used for a variety of digestive complaints, including IBS. Taking 3 to 6 peppermint concentrate capsules is equivalent to drinking 20 cups of mint tea a day.
