The kiwi originated in ancient China in the Yangtze River valley. In fact, the original name of the kiwi was the Chinese Gooseberry, as it is actually a berry. Khans prized it as an aphrodisiac.
Missionaries took the seeds to New Zealand at the turn of the 20th century where it came to be known as the kiwi, named after New Zealand's native bird. It became a popular plant there and was later sent to California. Those very vines are still growing in the Chico Plant Introduction Station. Kiwis are also grown in areas like Chile, South Africa and Italy.
The kiwi's long history as an aphrodisiac may be for several reasons. First, the kiwi looks to be a very fertile fruit, each containing about 1,500 seeds, every one needing to be pollinated. The pollen comes from male vines and only female vines produce fruit (this will definitely change the way I look at kiwi's when I buy them - is it male or female?). And once again, it seems to be a kiwi-man's world. In the vineyard each male plant is surrounded by a bevy of four females. One male vine is able to provide pollination services for all four. 30 beehives with around 30,000 bees in each one are brought into the vineyard at the appropriate time in summer when there are thousands of flowers on the male vines and the time is right for pollination.
Second, the kiwi is prized for its nutritional benefits. Kiwis contain natural seratonin. Serotonin, released in our bodies as a natural response to emotions, helps in calming the nerves thereby prolonging ejaculation. When the male body experiences the effects of serotonin, it has better lasting power as it improves the ability to handle the stimulation received during sex so as not to peak too soon. Most of the information I have come across talks about serotonin with regard to men but since serotonin also helps to receive sensory messages, things such as pain and pleasure are better experienced. I like that - well the pleasure part.
Kiwis contain zinc which helps improve testosterone levels and improve semen volume and sperm health.
Kiwis have more Vitamin C than an orange as well as being rich in vitamin E, vitamins key to sexual health.
The kiwi also has oral chelating agents that help clean the arteries to allow for better blood flow to genitalia in both sexes.
And speaking of genitalia, some foods are considered aphrodisiacs just by their appearance. This could be my number one reason the kiwi is considered an aphrodisiac. Just look at the picture above. (Blond or brunette I wonder.)
