i enjoy taking damiana due to its effect on my libido it's a general stimulant too by that i mean taking gel caps with water produces a bit of anxiety in my lower digestive tract this is not unpleasant as an herbal tea damiana didn't offer me the same benefit i take damiana in conjunction with maca and perhaps yohimbine the may be a little too much stimulation so i maintain the dosage of maca and damiana then use yohimbe on a recreational basis i can say taking the jointly does increase sexual interest need
