Did she spike your beer with Spanish Fly? Ya better hope not...

 There's little evidence to support the effectiveness of most substances thought of as natural aphrodisiacs - natural substances that may enhance sexual function,, but some of them can actually kill you.

Some foods and supplements are sometimes claimed to affect libido. These include chocolate, spicy food and saw palmetto. But research has found that they usually don't work to produce a sexual response in men or women. Some early evidence is a little more encouraging for a few natural supplements, but more research is needed. These include ginkgo, ginseng, maca and tribulus.

There's no harm in trying most foods to see if they're effective natural aphrodisiacs. Be aware that some supplements that have insect or plant extracts in them can be poisonous (toxic). For example, Spanish fly, a commonly advertised natural aphrodisiac, can cause kidney damage and bleeding in the digestive system.

 

Certain products sold as natural aphrodisiacs have also been found to include prescription drug ingredients that aren't listed on the label. For example, sildenafil, the active ingredient in Viagra, has been found in some products. These ingredients can be dangerous if you have certain medical conditions or take certain drugs.
