Maca (Lepidium meyenii) is a legendary aphrodisiac. And like many aphrodisiacs, its primary action is to nourish the body and rebuild depleted nutritional stores so that the neurotransmitters and hormones necessary for arousal can be more easily manufactured by the body. Just eat a few of these truffles and you’ll see what I mean. After all, our sexuality is simply an extension of our vital force.
