If 'health is wealth' then sexual health is the basis for striking the emotional balance of a person. If sex is a natural urge, then maintaining sexual health is of utmost importance as it plays an important role in matters of the heart. When we say matters of the heart, it does not only refer to the emotional aspect of the heart i.e. love but also indicates the physical aspect. Elaborating on the matter, 35% of men in the world are found to be having a sexual disorder like erectile dysfunction or impotence - which is revealed to be a warning sign for heart diseases. But impotence is not an untreatable disease anymore. Erectile dysfunction or ED is a medical condition caused mainly due to the hardening of the arteries. This is a condition when there is the formation of deposits on the layers of the penile arteries causing the erectile tissues to restrict the flow of blood thus preventing an erection. But erectile dysfunction is not an untreatable disease anymore. Nor are treatments as painful as it used to be in the earlier days. And treatment for impotence has become more hassle-free with the introduction of drug therapy pioneered by Pfizer's Viagra. There are a number of ED pills in the market that are available including pills like Levitra and Cialis. These drugs can easily be procured from online pharmacies. 시알리스 is one of the most promising drugs in this category. Marketed by Eli Lilly and Co., Cialis has in very little span acquired the trust of the consumers. Cialis has been responsible for rejuvenating the lives of many men suffering from erectile dysfunction. But this has been possible due to the presence of its active ingredient Tadalafil. Tadalafil works by relaxing the hardened penile arteries which improve the flow of blood thus facilitating erection. Taken an hour before sexual activity, Cialis remains in the body for 4 hours. But it is strongly recommended to consult a medical practitioner regarding fitness to have active sex and its dosage. Earlier men suffering from impotence hesitated to come out in the open and even speak to their doctors. But in this age of internet and online information, someone seeking information can easily have Cialis information from the innumerable websites dedicated to it. Also, you can buy Cialis from online pharmacies by placing an order for the privacy of your homes and even have it delivered at your footstep. This procedure of online marketing of ED pills have not only brought business growth for the drug dealers but has also been a helpful proposition for all those men who faced embarrassment in buying ED pills like Cialis, Viagra, and Levitra from over-the-counter pharmacies.
