Male enhancement products such as herbal dietary aids have bombarded many supermarkets and corner stores. But do these products really do sexual enhancement or are these used merely as placebo effect?Out of curiosity, I began reading the ingredients of some common libido enhancers. True enough, there are many herbs in the products which claim to do sexual enhancement such as sexual arousal through raising the levels of the sexual hormone called testosterone.Testosterone is a hormone secreted in the testes of men. It is responsible for sexual characteristics and sexual enhancements such as facial hair growth deepen of voice, enlargement of penis size, augment in muscular strength etc. Testosterone is also responsible for sexual aggression and desire, thus it is the main focus of products that promote male enhancement. Taking testosterone directly is a form of steroid use so manufacturers that trade products for male enhancement make use of herbal supplements in increasing testosterone levels naturally.The three main herbs used for sexual enhancements are the following: horny goat weed, ashwaganda and passionflower. Among the main herbs used, horny goat weed is by far the most beneficial for sexual enhancements. It increases the circulation of blood in the extremities. It lessens high blood pressure as well. However, too much horny goat weed may cause over aggressiveness and irritability.Passionflower is another herb used for male enhancement. It has been used to cure anxiety. The Native American attests to the positive effects of this herb. Passionflower lessens the levels of estrogen and maintains testosterone levels, therefore giving the user positive increase in levels of testosterone. Lessening of anxiety is beneficial for those with erectile dysfunction because it is the main reason for the existence of the dysfunction.Ashwaganda is also known as Indian Ginseng. It is another herb used to encourage sexual enhancement but has other benefits as well. It calms the nervous centers of the brain, therefore giving aid from constant exertion and stress. As aforementioned, decreasing stress is the main treatment for sexual dysfunctions and promote sexual enhancement. Athletes also benefit from Ashwaganda because it helps the body to recover from strenuous activities such as exercise. In addition, relief from sexual exertion is also another effect of the product.As with most medications, consultations with medical professionals are essential before using these male enhancement products. Medical advice along with enhancers may prove to be effective. However, self-medication and over use may worsen the sexual dysfunctions.
