We have recently informed you that, aside from the benefic effects on the sex life, Viagra is also good for people with high blood pressure.

But it seems that the drug has also other positive effects.
The Saarland University researchers have discovered that Viagra may ease symptoms of a circulatory disorder called Raynaud's phenomenon.

Raynaud's phenomenon, which affects 3 million to 5 million people worldwide, occurs when cold temperatures or stress cause small blood vessels in the skin to constrict, resulting in numbness, tingling and pain in toes and fingers. In severe cases, there's a risk of ulcerations.

The study compared outcomes in 16 patients (mostly women) with severe Raynaud's, who did not respond to standard treatment with drugs used to help dilate blood vessels.

The patients received either Viagra or a placebo for four weeks, and were then switched to the opposite treatment for another four weeks.

The conclusion was that Viagra had reduced the frequency and duration of Raynaud's attacks, improved capillary blood flow and helped heal chronic toe and finger ulcerations.
