Herbal viagra is a name that can be given to any herbal
product advertised as treating erectile dysfunction.[1] The name
Herbal viagra is taken from the brand name Viagra, the name
under which drug company Pfizer sells Sildenafil citrate, a drug
that is used to treat erectile dysfunction.[2] There are many
different products being advertised as herbal viagra, all being
made with different ingredients. One product, Duro is known to
contain an extract of fungus extracted from the larval remains
of silkworms. Duro is also said to benefit sportsmen and women
through increased stamina.[3] Many of these herbal remedies
originate from ancient tribes, such as Mapuche Viagra which is
used by Chile's Mapuche people.[4] Herbal viagras, contrary to
what the name suggests, do not normally contain Sildenafil
Citrate. Viagra has become a generic term for many people
discussing drugs designed to treat erectile disfunction.[5]
Herbal viagras often carry a number of dangerous side effects,
primarily they often cause abnormally low blood pressure and can
restrict blood flow to vital organs. There is also evidence to
suggest some preparations may be toxic if taken in larger
doses.[1] Herbal viagra is predominantly sold through the
internet, and in 2003, around 4% or 1 in 25 of all e-mail
messages sent offered herbal viagra, genuine pharmaceuticals and
other herbal remedies.
