Some men – and a good few women – are not averse to taking Viagra to give their sex lives a little extra spice even though they don’t really need it. Personally I’ve always been wary of buying prescription drugs over the net, as this can be very dangerous. Here’s a smart alternative. Holland and Barrett have a range of natural products created to enhance your libido. These include Horny Goat Weed (available in male and female varieties) which is believed to naturally improve libido; Damiana Leaves which were originally used by indigenous cultures of Central America to improve libido and stimulate oxygen flow to the genitals to improve potency; and Muira Puama, known as ‘potency wood’ which was used by Brazil’s indigenous tribes as an aphrodisiac, to treat erectile dysfunction and to help maintain an erection.
