Fugu

There’s nothing like a near-death experience to get you and your partner in the mood. Handled improperly, fugu (or blowfish) has enough tetrodotoxin to poison you 30 times over! Many people have died from eating fugu, but if prepared the right way, it leaves adventurous eaters with a tingling sensation that is said to be one of the reasons it increases libido. You can safely help yourself to fugu in Japan, as long as the chef who prepares it has the special license and technique to handle it properly.
Ambergris

Secreted by a sperm whale, ambergris is used both as a food and as an ingredient in some luxury perfumes. Casanova apparently used ambergris-infused perfume to make the ladies swoon, and it has a history in the Middle East of being consumed to increase a man’s virility. One royal family in that region reportedly combines ambergris with milk and honey to create the passion-inducing dish.
Ambergris is banned in many countries however, including Australia and the US, because of the endangered status of the sperm whale. But in other countries, including the UK and those in the European Union (EU), it is legal to salvage a lump of ambergris from beaches and sell it. Although all whale and dolphin species are protected under EU law, ambergris is regarded as an excretion, and therefore a benign byproduct.
Spanish fly

Whale secretions aren’t the only kind on this list. The secretions of the Spanish fly (which is really a type of beetle) are thought to be nature’s Viagra. Consuming it can prepare a man’s body for sex (if you catch our drift), but it can also come with some pretty uncomfortable side effects. Blistering and urinary tract problems can occur as a result of consuming the Spanish fly’s secretions. Still, people buy it all over Europe.
