How long till the plant [winter-flowering heather], is on the dangerous drug list due to the fact that the sex pill is the best money maker that the drug industry has ever came up with.
A chance discovery by a Berkshire allotment-holder that a plant widely available in garden centres has the same effect on men as Viagra has been confirmed by experts at one of the world's leading botanical institutions.
The plant is winter-flowering heather, and botanists at the Royal Botanic Gardens, Edinburgh, many of them heather experts who have recognised the source of its active ingredient, now expect it to be the next must-have plant in British gardens. Demand is already high. Nurseries and garden centres in some areas are having trouble finding sufficient supplies as word spreads of the plant's unexpected properties.
