The ingredients include basic herbal and vitamin remedies such as zinc and niacin. The “proprietary blend” is the bulk of the pills and include gingko biloba and ginseng extracts as well as something curiously called horny goat weed. Also known as epimedium or yin yang huo, the plant is from old Chinese medicine and consists of many species of the leafy plant. Touted for the ability to increase libido, what is known is that the plant contains flavonoids, sterols, complex sugars (polysaccharides), and magnaflorine. Flavonoids are antioxidants found in fruits and vegetables. What benefits the pills may deliver can actually be achieved by a good diet.
