Be cautious of trying anything "natural", as that can mean a lot of things, and quite often there is no scientific proof that the "natural" remedies work other than anecdotal responses by certain individuals. I would suggest that you go in for a general checkup with your personal physician, internist, or other medical professional, including a blood workup that would be recommended--all depending upon your health insurance level. It would be interesting to know if you've had a sex drive in the past, if that drive went away slowly or suddenly, if you are taking medications, if you are under undo stress, and so on. Do you see a need for a sex drive or can you enjoy life without that, at this time, as not everyone is required to have the same needs all through one's life? But first, rule out any medical problems that would be revealed by a checkup.
yeah I also heard DHEA helps. Maybe you need to have your hormones checked by your doctor. You may be defficient in testosterone or something
First you need to decide if it happening from type of medication you are taking or some physical problem you are having. If not, there are supplements such a ginko bolabu (sp) that could help.
