problem with boosting testosterone with anything including herbs is that you will also increase your estrogen, this in effect will lower you T in the long run. I highly recommend D.I.M, Diindolylmethane. is a phytochemical found in vegetables and helps your body cleanse its self naturally of excess estrogen. Which in turn will keep your testosterone up in the long run. Eat broccoli cabbage sauerkraut and other cruciferous vegetables as they are an excellent source of Diindolylmethane. Zinc also is great for naturaly healthy T levels, good sources include red meat and oysters.
