Some other things. L-arginine tablets, an amino acid. Take 3 grams per day on an empty stomach with water, all at once, early in the day. Drink green tea, especially if you can sweeten it with raw honey. A multivitamin with minerals is good.

Ginseng is a good herb.

Also, you are probably low on zinc.
