Natural Cures for Impotence
NOTE:
4. Some people provide natural
cures for impotence by means of mixing such plants
as clover,
mint, tutsan and nettle.
Several websites suggest a "cure" includes adding "Mint" to ones diet

Bottom Line: Google is not research but a search of websites
If "Mint" causes impotence you can bet your favorite PV it would
be all over the news and many Mint flavored products would not
be on the market including Wrigley's Double Mint chewing gum.
Also ... Why is there "mint flavored" ...... ??
Suggest asking your pharmacist and your doctor if consuming
Mint flavored products cause impotence.
Let us know what they say.
